Abstract: This research identified profiles characterized by distinct levels of overcommitment, rumination, psychological detachment (Studies 1 and 2), and need for recovery (Study 2). This research also considers the role of hindrance demands and resources in the prediction of profile membership, and the outcomes of these profiles. These objectives were addressed in two empirical cross-sectional studies relying on self-reported questionnaires. Study 1 relies on a convenience s le of French workers from a variety of occupations. Study 2 relies on a convenience s le of French nurses and nursing assistants. Latent profile analyses revealed four identical profiles in both studies ( Theoretical contributions and implications for practice are discussed.

Abstract: Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), path analysis, and structural equation modeling (SEM) have long histories in clinical research. Although CFA has largely superseded EFA, CFAs of multidimensional constructs typically fail to meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differentiated factors in support of discriminant validity. Part of the problem is undue reliance on overly restrictive CFAs in which each item loads on only one factor. Exploratory SEM (ESEM), an overarching integration of the best aspects of CFA/SEM and traditional EFA, provides confirmatory tests of a priori factor structures, relations between latent factors and multigroup/multioccasion tests of full (mean structure) measurement invariance. It incorporates all combinations of CFA factors, ESEM factors, covariates, grouping/multiple-indicator multiple-cause (MIMIC) variables, latent growth, and complex structures that typically have required CFA/SEM. ESEM has broad applicability to clinical studies that are not appropriately addressed either by traditional EFA or CFA/SEM.

Abstract: This research relies on complementary variable‐ and person‐centred approaches to investigate the underlying dimensionality of the workaholism construct. In three studies (Study 1: N = 343 workers Study 2: N = 654 firefighters in S le 1 and N = 247 administrative and technical employees in S le 2 and Study 3: N = 153 nurses in S le 1 and N = 359 educators in S le 2), the results showed that employees' workaholism ratings simultaneously reflected a global overarching workaholism construct, which co‐existed with two specific dimensions (working excessively and compulsively). In Study 1, global levels of self‐determined motivation were associated with higher global levels of workaholism, whereas perceived supervisor support was negatively related to global levels of workaholism. We then examined the distinct configurations, or profiles, taken by workaholism dimensions (global workaholism, and specific working excessively and compulsively Studies 2 and 3) and psychological detachment (Study 3). Studies 2 and 3 also documented the associations between these workaholism profiles, and correlated predictor (e.g. supervisor support, workload) and outcome (e.g. emotional exhaustion, work performance) variables. Three of the four profiles identified were similar across studies ( Low Global and Average Specific Workaholism , Average Global and Specific Workaholism and High Global and Average Specific Workaholism ), whereas one profile was different across studies and s les. In both studies, the High Global and Average Specific Workaholism profile was associated with the worst correlated outcome variables (e.g. high levels of emotional exhaustion, low levels of job satisfaction).

Abstract: The purpose of this paper is to investigate the possibility of curvilinear patterns of relationships between workplace affective commitment and in‐role performance, organizational citizenship behaviors and burnout. As most commitment theories assume strictly linear relations with these outcomes, demonstrating that these positive associations do not hold above some ceiling point in the commitment continuum is potentially important for research and practice. The possibility of nonlinear relations was examined in a s le of 273 hospital employees. The results yielded strong support for the authors' hypotheses. Indeed, most of the relations observed (ten of 15) between affective commitment foci and work outcomes were curvilinear, revealing a ceiling to the positive association between commitment and outcomes. Although these results vary in strength across work outcomes and commitment targets, they reveal that affective commitment has negative associations with employee productivity and psychological health at extreme levels. Methodologically, these results illustrate the need to systematically explore the true nature of relations among constructs, even in areas where it is assumed to be well known. Practically, these results suggest that, ultimately, moderate levels of commitment may be more beneficial than extremely high levels.

Abstract: This study aims to investigate the direct and indirect associations between physical self-subdomains, physical self-worth, global self-worth, and disturbed eating attitudes and behaviors among French non-elite athlete and non-athlete adolescent girls. A s le of adolescent girls including 50 ballet dancers, 41 basketball players, and 47 non-athletes was used in this study. Data obtained from the ballet dancer and basketball player subs les revealed significant, s le-specific as well as common, direct relations between global and physical self-perceptions and disturbed eating attitudes and behaviors, as well as significant indirect relations (via global self-worth and physical self-worth) between specific physical self-perceptions and disturbed eating attitudes and behaviors. In contrast, no association was found between global and physical self-perceptions in the s le of non-athlete adolescent girls.

Abstract: Youth with intellectual disability (ID) are at an increased risk of displaying fewer prosocial behaviors and more numerous aggressive behaviors in various environments. This study proposes a new multi-informant (youth, teachers, and parents) measure of social behaviors for youth with ID. The s le includes 348 youth with mild (51.41%) and moderate (48.59%) levels of ID, aged 11-22 years old (M = 15.73, SD = 2.14 including 138 females), enrolled in secondary schools in Canada (French-speaking N = 116 33.33%) and Australia (English-speaking N = 232 66.67%). Measures were completed by the participants, their teachers, and their parents. Results support the reliability, factor validity, discriminant validity (in relation to sex, ID level, and country), concurrent validity (with measures of victimization, depression, hyperactivity-inattention), and one-year test-retest stability of the measure. Youth, teachers, and parents all provided a complementary perspective on youth social behaviors, consistent with youth adjusting their behaviors to the various environments in which they share social interactions.

Abstract: The most popular measures of multidimensional constructs typically fail to meet standards of good measurement: goodness of fit, measurement invariance, lack of differential item functioning, and well-differentiated factors that are not so highly correlated as to detract from their discriminant validity. Part of the problem, the authors argue, is undue reliance on overly restrictive independent cluster models of confirmatory factor analysis (ICM-CFA) in which each item loads on one, and only one, factor. Here the authors demonstrate exploratory structural equation modeling (ESEM), an integration of the best aspects of CFA and traditional exploratory factor analyses (EFA). On the basis of responses to the 11-factor Motivation and Engagement Scale ( n = 7,420, M age = 14.22), we demonstrate that ESEM fits the data much better and results in substantially more differentiated (less correlated) factors than corresponding CFA models. Guided by a 13-model taxonomy of ESEM full-measurement (mean structure) invariance, the authors then demonstrate invariance of factor loadings, item intercepts, item uniquenesses, and factor variancescovariances, across gender and over time. ESEM has broad applicability to other areas of research that cannot be appropriately addressed with either traditional EFA or CFA and should become a standard tool for use in psychometric tests of psychological assessment instruments.

Abstract: Elite athletes and nonathletes ( N = 1,268) attending the same selective sport high school (4 high school age cohorts, grades 7–10, mean ages varying from 10.9 to 14.1) completed the same physical self-concept instrument 4 times over a 2-year period (multiple waves). We introduce a latent cohort-sequence analysis that provides a stronger basis for assessing developmental stability/change than either cross-sectional (multicohort, single occasion) or longitudinal (single-cohort, multiple occasion) designs, allowing us to evaluate latent means across 10 waves spanning a 5-year period (grades 7–11), although each participant contributed data for only 4 waves, spanning 2 of the 5 years. Consistent with the frame-of-reference effects embodied in the big-fish-little-pond effect (BFLPE), physical self-concepts at the start of high school were much higher for elite athletes than for nonathlete classmates, but the differences declined over time so that by the end of high school there were no differences in the 2 groups. Gender differences in favor of males had a negative linear and quadratic trajectory over time, but the consistently smaller gender differences for athletes than for nonathletes did not vary with time.

Abstract: The main objective of the present series of studies was to test the construct validity (i.e., content, factorial, and convergent validities) of the Fear of Negative Appearance Evaluation Scale (FNAES) in a community s le of French adolescents. A total s le of 683 adolescents was involved in three studies. The factorial validity and the measurement invariance of the FNAES were verified through a series of confirmatory factor analyses. The convergent validity of the FNAES was then verified through correlational analyses. The first study showed that the content and formulation of the French FNAES items were adequate for children and adolescents. The following two studies (Studies 2 to 3) provided (a) support for the factor validity, reliability, and convergent validity of a five-item French version of the FNAES, and (b) partial support for the measurement invariance of the resulting FNAES across genders. However, the latent mean structure of the FNAES did not prove to be invariant across genders, revealing a significantly higher latent mean score of FNAES in girls relative to boys. The present results, thus, provide preliminary evidence regarding the construct validity of the FNAES in a community s le of French adolescents. Recommendations for future practice and research regarding this instrument are outlined.

Abstract: This study investigates associations between initial levels and change in the quality of the relationships youth with intellectual disabilities (ID) share with their parents and teachers, and changes in their levels of depression over time. A s le of 395 youth with mild (48.3%) and moderate (51.7%) ID, aged between 11 and 22 (M = 15.69), were recruited in Canada (n = 142) and Australia (n = 253). Youth completed self-report measures of relationship quality and depression twice over a one-year period. Initial levels of warmth (β = - .109) and conflict (β = - .302) predicted decreases in depression. Increases in warmth predicted decreases in depression (β = - .179), while increases in conflict predicted increases in depression (β = .268). Discrepancies between youth relationships with their parents and teachers predicted decreases in depression (β

Abstract: In planar magnetic resonance imaging (MRI) systems, gradient coils are usually placed within a very limited space owing to the physical constraints of the small gap size (pole-pole) distance of the permanent magnet. Typically, the unshielded or partially shielded design scheme is adopted to generate required magnetic fields with reduced system costs. However, non-fully shielded coils can induce large eddy currents on the surrounding metal structures, including magnet poles, that significantly impact the imaging performance. This paper elaborates a new design strategy to resolve the limited space problem. Using the peripheral sections of the MRI system, a set of actively shielded gradient coils are purposefully designed. Between the two magnet poles, the actively shielded gradient coils occupy merely four coil layers (six coil layers are usually required), which offers an excellent shielding effect, thus reducing the image distortions. The saved space can be used to integrate a high-efficient cooling system. Moreover, the design scheme does not significantly increase the fabricating complexity.

Abstract: Previous research on the Center for Epidemiologic Studies Depression Scale (CES-D) has five main limitations. First, no study provided evidence of the factorial equivalence of this instrument across s les of depressive and community participants. Second, only one study included systematic tests of measurement invariance based on confirmatory factor analyses (CFA), and this study did not consider the higher-order factor structure of depression, although it is the CES-D global scale score that is most often used in the context of epidemiological studies. Third, few studies investigated the screening properties of the CES-D in non-English-language s les and their results were inconsistent. Fourth, although the French version of the CES-D has been used in several previous studies, it has never been systematically validated among community and/or depressed adults. Finally, very few studies have taken into account the ordered-categorical nature of the CES-D answer scale. The purpose of the study reported herein was therefore to examine the construct validity (i.e., factorial, reliability, measurement invariance, latent mean invariance, convergence, and screening properties) of the CES-D in a French s le of depressed patients and community adults. A total s le of 469 participants, comprising 163 clinically depressed patients and 306 community adults, was involved in this study. The factorial validity, and the measurement and latent mean invariance of the CES-D across gender and clinical status, were verified through CFAs based on ordered-categorical items. Correlation and receiver operator characteristic curves were also used to test the convergent validity and screening properties of the CES-D. The present results: (i) provided support for the factor validity and reliability of a second-order measurement model of depression based on responses to the CES-D items (ii) revealed the full measurement invariance of the first- and second-order measurement models across gender (iii) showed the partial strict measurement invariance (four uniquenesses had to be freely estimated, but the factor variance-covariance matrix also proved fully invariant) of the first-order factor model and the complete measurement invariance of the second-order model across patients and community adults (iv) revealed a lack of latent mean invariance across gender and across clinical and community subs les (with women and patients reporting higher scores on all subscales and on the full scale) (v) confirmed the convergent validity of the CES-D with measures of depression, self-esteem, anxiety, and hopelessness and (vi) demonstrated the efficacy of the screening properties of this instrument among clinical and nonclinical adults. This instrument may be useful for assessing depressive symptoms or for the screening of depressive disorders in the context of epidemiological studies targeting French patients and community men and women with a background similar to those from the present study.

Abstract: In this study, we investigated the role of psychological empowerment as a protective factor for burnout among workers exposed to work-related stressors (e.g. daily hassles, overload, job changes). A cross-sectional questionnaire study was conducted, with a convenience s le of 401 healthcare workers. Hierarchical multiple regressions were performed to test main and moderating effects of empowerment cognitions. Results revealed partial support for the hypotheses. Only the job meaningfulness cognition exerts a beneficent main effect on all burnout symptoms beyond the effect of stressors. Some moderating effects differing according to burnout dimensions were also found. Most interestingly, high levels of empowerment cognitions accentuate the effect of change-related resources in the reduction of emotional exhaustion. Because psychological empowerment has beneficial effects, organizations could rely on different strategies to enhance it.

Abstract: Latent curve models (LCMs) have been used extensively to analyze longitudinal data. However, little is known about the power of LCMs to detect nonlinear trends when they are present in the data. For this study, we utilized simulated data to investigate the power of LCMs to detect the mean of the quadratic slope, Type I error rates, and rates of nonconvergence during the estimation of quadratic LCMs. Five factors were examined: the number of time points, growth magnitude, interin idual variability, s le size, and the R (2)s of the measured variables. The results showed that the empirical Type I error rates were close to the nominal value of 5 %. The empirical power to detect the mean of the quadratic slope was affected by the simulation factors. Finally, a substantial proportion of s les failed to converge under conditions of no to small variation in the quadratic factor, small s le sizes, and small R (2) of the repeated measures. In general, we recommended that quadratic LCMs be based on s les of (a) at least 250 but ideally 400, when four measurement points are available (b) at least 100 but ideally 150, when six measurement points are available (c) at least 50 but ideally 100, when ten measurement points are available.

Abstract: Given the detrimental effects associated with problematic internet use (PIU) and the need to better understand its nature and evolution, the present study examined the development of PIU in a s le of 1,750 adolescents (aged 16–19) from Finland over a 3‐year period. We documented the social (loneliness, perceived maternal and paternal behaviors) and in idual (sex) antecedents, as well as the outcome implications (depressive symptoms, substance use, academic achievement) of PIU trajectories. Outcomes also predicted PIU trajectories. Latent curve modeling revealed an initially moderate, and subsequently decreasing trajectory of PIU. PIU was predicted by loneliness, paternal neglect, maternal care, depressive symptoms, and being male. In turn, PIU trajectories predicted increases in depressive symptoms and substance use, but decreases in academic achievement.

The, first study provided support for the item content of the preliminary version of the French SPAS for adolescents. Then, the second study supported the convergent validity of the English and French version of the SPAS. Finally, Studies 3 to 6 provided support for the factor validity, measurement invariance (across genders, age groups and s les), latent mean structure invariance (across age category and s les), reliability, convergent validity, and criterion-related validity of a 7-item version of the SPAS.

Abstract: The purpose of the present four‐wave longitudinal study was to examine the differentiation and reciprocal associations between burnout and depression, and their associations with a series of correlates related to employees’ physical and psychological health (sleep disturbances, somatic symptoms, self‐rated subjective health, and life satisfaction). A total of 542 early career Finnish workers filled out questionnaires four times over a period of 8 years. First, our results supported the superiority of a bifactor exploratory structural equation modeling (bifactor‐ESEM) representation of employees’ burnout ratings, and the empirical differentiation between burnout and depression ratings over each measurement occasion. These results further revealed moderate cross‐sectional associations between burnout and depression, supporting their inter‐related character but also their empirical distinctiveness. Second, autoregressive cross‐lagged analyses revealed that both constructs presented a moderate level of stability over time and reciprocal associations that generalized to all time intervals considered. Finally, relations between depression and all correlates measures during the last wave of the study were in the expected direction, whereas burnout was found to be more weakly related to only a subset of these correlates. Taken together, these results thus support the distinctiveness of burnout and depression, and the presence of mutually reinforcing relations between them.

Abstract: Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8-10) in matched s les of 138 adolescents (34.78 % girls) with low levels of cognitive abilities and 556 adolescents (44.88 % girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within s les of adolescents with low, and average-to-high levels of cognitive ability.

Abstract: The present investigation has a dual focus: to evaluate problematic practice in the use of item parcels and to suggest exploratory structural equation models (ESEMs) as a viable alternative to the traditional independent clusters confirmatory factor analysis (ICM-CFA) model (with no cross-loadings, subsidiary factors, or correlated uniquenesses). Typically, it is ill-advised to (a) use item parcels when ICM-CFA models do not fit the data, and (b) retain ICM-CFA models when items cross-load on multiple factors. However, the combined use of (a) and (b) is widespread and often provides such misleadingly good fit indexes that applied researchers might believe that misspecification problems are resolved--that 2 wrongs really do make a right. Taking a pragmatist perspective, in 4 studies we demonstrate with responses to the Rosenberg Self-Esteem Inventory (Rosenberg, 1965), Big Five personality factors, and simulated data that even small cross-loadings seriously distort relations among ICM-CFA constructs or even decisions on the number of factors although obvious in item-level analyses, this is camouflaged by the use of parcels. ESEMs provide a viable alternative to ICM-CFAs and a test for the appropriateness of parcels. The use of parcels with an ICM-CFA model is most justifiable when the fit of both ICM-CFA and ESEM models is acceptable and equally good, and when substantively important interpretations are similar. However, if the ESEM model fits the data better than the ICM-CFA model, then the use of parcels with an ICM-CFA model typically is ill-advised--particularly in studies that are also interested in scale development, latent means, and measurement invariance.

Abstract: The in idually importance-weighted average (IIWA) model posits that the contribution of specific areas of self-concept to global self-esteem varies systematically with the in idual importance placed on each specific component. Although intuitively appealing, this model has weak empirical support thus, within the framework of a substantive-methodological synergy, we propose a multiple-item latent approach to the IIWA model as applied to a range of self-concept domains (physical, academic, spiritual self-concepts) and subdomains (appearance, math, verbal self-concepts) in young adolescents from two countries. Tests considering simultaneously the effects of self-concept domains on trait self-esteem did not support the IIWA model. On the contrary, support for a normative group importance model was found, in which importance varied as a function of domains but not in iduals. In iduals differentially weight the various components of self-concept however, the weights are largely determined by normative processes, so that little additional information is gained from in idual weightings.

Abstract: The authors adopt a person-centered approach to the investigation of the dimensionality of the union commitment construct by capitalizing on a 10-year longitudinal study (from 1992 to 2002) of 637 union members in their first year of employment measured again 1 and 10 years later. Results reveal four distinct profiles of union commitment, presenting a stable structure over time. These profiles demonstrate consistency in commitment level across the three most common union commitment dimensions, thus questioning the necessity of adopting a multidimensional approach. Results show that union members became more similar to other members of their profiles over time, and that their union commitment became slightly less extreme as union tenure increased. Finally, results show that union commitment profiles predict union participation, in accordance with our expectations, and suggest that endorsing positive attitudes toward unions and their instrumentality was a stronger predictor of profile membership than was satisfaction with the actions of one’s own union.

Abstract: Most previous studies have failed to replicate the original factor structure of the 26-item version of the Eating Attitudes Test (EAT-26) among community s les of adolescents. The main objective of the present series of four studies (n = 2178) was to revisit the factor structure of this instrument among mixed gender community s les of adolescents using both exploratory structural equation modeling (ESEM) and confirmatory factor analysis (CFA). First, results from the ESEM analyses provided satisfactory goodness-of-fit statistics and reliability coefficients for a six-factor model of the EAT with 18 items (EAT-18) closely corresponding to the original seven-factor structure proposed for the 40-item version of the EAT. Second, these analyses were satisfactorily replicated among a new s le of community adolescents using CFA. The results confirmed the factor loading and intercept invariance of this model across gender and age groups (i.e., early and late adolescence), as well as the complete invariance of the EAT-18 measurement model between ethnicities (i.e., European versus African origins) and across weight categories (i.e., underweight, normal weight and overweight). Finally, the last study provided support for convergent validity of the EAT-18 with the Eating Disorder Inventory and with instruments measuring global self-esteem, physical appearance, social physique anxiety and fear of negative appearance evaluation.

Abstract: Recently, Marsh, Martin, and Jackson (2010) developed a short form of the Physical Self-Description Questionnaire (PSDQ-S). The objective of this study was to examine the construct validity and reliability of the PSDQ-S in a French adolescent s le. The s le used in this study included 587 adolescents (247 boys, 340 girls, Mage=14.62). Confirmatory factor analyses (CFA) provided support for the factor validity, reliability, and convergent validity of the French version of the PSDQ-S, and the strict measurement invariance of PSDQ-S across sex, age, body mass index, and involvement or not in sport practice. However, the latent means of the PSDQ-S did not prove to be invariant across sex, body mass index, and involvement or not in sport practice. Our findings suggest that the French version of the PSDQ-S presents acceptable psychometric properties and may be confidently used in research or practice to assess the physical self-conceptions of French adolescents.

Abstract: This study proposes a multi-informant (youth, teachers, and parents) measure of relationship quality with adults for youth with intellectual disabilities (ID). A s le of 395 youth with mild (49.15%) and moderate (50.85%) ID, aged 11-22 (M = 15.82) was recruited in Canada (French-speaking, N = 142), and Australia (English-speaking, N = 253). Results support the reliability, factor validity, discriminant validity (in relation to sex, ID level, country, and comorbidity), convergent validity (depression, anxiety, aggressiveness, and prosocial behaviors), and one-year longitudinal stability of the measure. Youth self-reports provide a complementary perspective on relationship quality with adults relative to teachers' or parents' reports, whereas teachers and parents seem unable to differentiate their own perspective from that of the target youth.

Abstract: Drawing on the expectancy-value model, the present study explored in idual and gender differences in university entry and selection of educational pathway (e.g., science, technology, engineering, and mathematics [STEM] course selection). In particular, we examined the multiplicative effects of expectancy and task values on educational outcomes during the transition into early adulthood. Participants were from a nationally representative longitudinal s le of 15-year-old Australian youths (N = 10,370). The results suggest that (a) both math self-concept and intrinsic value interact in predicting advanced math course selection, matriculation results, entrance into university, and STEM fields of study (b) prior reading achievement has negative effects on advanced math course selection and STEM fields through math motivational beliefs and (c) gender differences in educational outcomes are mediated by gender differences in motivational beliefs and prior academic achievement, while the processes underlying choice of educational pathway were similar for males and females.

Abstract: The purpose of this study was to test the factor validity and reliability of the Very Short Form of the Physical Self-Inventory- (PSI-VSF) within a s le of adolescents with mild to moderate Intellectual Disability (ID). A total of 362 ID adolescents were involved in two studies. In Study 1, the content and format scale response of the PSI-VSF were adapted for adolescents with ID. This instrument was thus renamed PSI-VSF-ID and two versions with two alternative responses scales format, were developed: Likert and graphical. In Study 2, results provided support for: (1) the factorial validity and reliability and (2) factorial invariance across gender, age, type of school placement and ID level of the PSI-VSF-ID associated with a graphical response scale format.

Abstract: Motives underlying sport and exercise involvement have recently been hypothesized as potential factors influencing the positive association between sports/exercises involvement and disturbed eating attitudes and behaviours (DEAB) among adolescents. Nevertheless, very few studies have examined this hypothesis or the moderating role of gender, context of practice, performance levels and sport type on these relationships. In this study, these questions were addressed among 168 male and 167 female French adolescents involved in various types, contexts and performance levels of sport and exercise. Participants were asked to indicate their main motives for involvement in sport practice and to self-report DEAB (generic DEAB, vomiting-purging behaviours, and eating-related control) on a French adaptation of the Eating Attitudes Test-26. The results shared positive associations between body-related sport and exercise motives and most of the DEAB subscales. Furthermore, they show that the relationship between body-related sport and exercise motives and Vomiting-Purging Behaviours differs according to involvement in in idual and competitive sports and exercises.

Abstract: This study investigates the nature of the social interaction profiles observed among youth with intellectual disabilities (ID), defined while considering their relationships with their parents, peers, and teachers, as well as the implication of these profiles for self-esteem, aggressive behaviors, and prosocial behaviors. A s le of 393 youth with mild (48.2%) to moderate (51.8%) levels of ID, aged between 11 and 22 (M = 15.70), was recruited in Canada (n = 141) and Australia (n = 253). Our results revealed four profiles, corresponding to Socially Isolated (23.24%), Socially Integrated (39.83%), Socially Rejected (28.37%) and Socially Connected (8.57%) youth with ID. The socially integrated and connected profiles both presented higher self-esteem, more prosocial behaviors, and less aggressive behaviors than the socially isolated and rejected profiles.

Abstract: The purpose of this meta-analytic study was to determine the pooled prevalence estimates of anxiety and depressive disorders among children and adolescents with intellectual disabilities (ID) and to assess the extent to which these pooled prevalence rates differed according to studies' characteristics. A systematic literature search was performed in nine databases and 21 studies, published between 1975 and 2015, met the inclusion criteria. The resulting pooled prevalence estimates of combined subtypes of anxiety and depressive disorders were respectively (a) 5.4% and 2.8% across s les (b) 1.2% and 0.03% among children and (c) 7.9% and 1.4% among adolescents. Pooled prevalence estimates for specific subtypes of anxiety disorders ranged from (a) 0.2% to 11.5% across s les (b) 0.7% to 17.6% among children and (c) 0.6% to 19.8% among adolescents. Pooled prevalence estimates of dysthymic disorder and major depressive disorder were respectively (a) 3.4% and 2.5% across s les (b) 2.1% and 3.2% among children and (c) 6.9% and 5.7% among adolescents. Finally, subgroup analyses showed significant variations in the pooled prevalence estimates of combined subtypes of anxiety disorders, obsessive-compulsive disorder, and generalized anxiety disorder and combined subtypes of depressive disorders. The present findings of this meta-analysis should be interpreted with caution given several limitations related to the characteristics of the populations, diagnostic method and s ling method. Findings provide recommendations for future studies investigating psychological disorders among youth with ID, as well as how clinicians and policy makers can improve diagnostic practices and support for youth with ID.

Abstract: This research addresses recent calls for an alternative integrative framework to apprehend leaders' behaviors and examines the validity ofaquestionnaire anchored in this theoretical approach. Building upon Self‐Determination Theory, we examined a tripartite approach of supervisors' behaviors (supportive, thwarting, and indifferent toward subordinates' psychological needs). The psychometric properties of this Tripartite Measure of Interpersonal Behaviors‐Supervisor (TMIB‐S) were tested through three studies. Results from bifactor exploratory structural equation modeling supported a solution including one global factor and three specific factors reflecting need supportive, thwarting, and indifferent behaviors. This solution was fully invariant across distinct s les of French‐ and English‐speaking employees. Results also supported the criterion‐related and discriminant validity of the TMIB‐S. More specifically, results supported the added‐value of the TMIB‐S, when compared to well‐established measures of leadership (passive leadership, abusive supervision, LMX, and tranformational leadership) in predicting well‐ and ill‐being. Results also highlighted well‐differentiated effects of the different components of supervisory behaviors and showed that supervisors' need indifferent behaviors constitute a key piece in the prediction of employees' health‐related consequences.

Abstract: The Strengths and Difficulties Questionnaire (SDQ) is used to measure psychopathological symptoms in children and adolescents from 4 to 17 years old, but its underlying structure is still a matter of debate. Indeed, on the basis of a systematic review of English and non-English articles conducted using multiple databases, 54 studies reporting on the factor structure of the SDQ were located. The original 5 first-order factor structure is generally supported by exploratory procedures, but support based on confirmatory factor analyses is not clear. We analysed data from 889 youths from the general French population, rated on the SDQ by their teachers. We tested the original model, hierarchical models and bifactor models. The best-fitting model is a bifactor model with the five a priori factors grouped in two global factors (Externalizing Disorders-Hyperactivity and Conduct-and Internalizing Disorders-Peer relationships and Emotions) and one Strength/Prosocial factor. However, we show that the Conduct-Specific factor should not be used in practice in its current state, that the Hyperactivity-Specific factor mainly covers hyperactivity rather than inattention, and that the Peer Problems-Specific factor mainly reflects a preference for solitude. Nevertheless, the measurement model proved to be fully invariant across gender and school levels (kindergarten, primary and secondary schools), with statistically significant differences in latent means between genders only. Beyond computing the five a priori scores when using the teacher ratings of the SDQ, our results prove the usefulness of computing Externalizing Disorders and Internalizing Disorders global scores.

Abstract: Recently Maïano, Bégarie, Morin, and Ninot (2009) developed and validated an intellectual disability (ID) version of the very short form of the physical self-inventory (PSI-VS-ID). In a recent review of the various physical self-concept instruments Marsh and Cheng (in press) noted that the short and very short versions of the French PSI represent an important contribution to applied research but that further research was needed to investigate the robustness of their psychometric properties in new and ersified s les. Thus, this study is specifically designed to investigate the robustness of the PSI-VS-ID psychometric properties in a new independent s le of 248 adolescents and young adults with ID. In particular, tests of measurement invariance were conducted across the present s le and the original s le from Maïano et al. (2009) study in order to more precisely assess the degree of replication of the results. Overall, results from a series of confirmatory factor analyses of the PSI-VS-ID provided support for its: (i) factorial validity and reliability (ii) factorial invariance across gender and weight status (iii) partial (strict or strong) factorial invariance across age, ID level and s les and (iv) latent mean differences across gender, weight status and ID level groups.

Abstract: Students with intellectual disabilities (ID) are at increased risk of peer victimization and depressive symptoms. Little is known about the protective and aggravating factors that influence the association between peer victimization and depressive symptoms among students with ID. This study assesses the moderating role of two facets of teacher-student relationships (TSR)-warmth and conflict-on the association between peer victimization and depressive symptoms. A s le of 395 students (aged 11-22) with mild and moderate ID was recruited in Canada and Australia. Hierarchical multiple regressions indicated that victimization and TSR conflict were both associated with higher levels of depressive symptoms, and that TSR conflict moderated the associations between both TSR warmth and victimization, and depressive symptoms. TSR warmth was related to lower levels of depression only for students who also reported a low level of TSR conflict. Similarly, associations between victimization and depression were weaker among students exposed to more conflictual TSR. Students with ID are at increased risk of developing depressive symptoms when exposed to negative social relationships (i.e., peer victimization or TSR conflict). For these students, the benefits of TSR warmth were far less important than the consequences of conflict.

Abstract: The current study aims to explore the usefulness of a person-centered perspective to the study of workplace affective commitment (WAC). Five distinct profiles of employees were hypothesized based on their levels of WAC directed toward seven foci (organization, workgroup, supervisor, customers, job, work, and career). This study applied latent profile analyses and factor mixture analyses to a s le of 404 Canadian workers. The construct validity of the extracted latent profiles was verified by their associations with multiple predictors (gender, age, tenure, social relationships at work, workplace satisfaction, and organizational justice perceptions) and outcomes (in-role performance, organizational citizenship behaviors, and intent to quit). The analyses confirmed that a model with five latent profiles adequately represented the data: (a) highly committed toward all foci (b) weakly committed toward all foci (c) committed to their supervisor and moderately committed to the other foci and (d) committed to their career and moderately uncommitted to the other foci (e) committed mostly to their proximal work environment. These latent profiles present theoretically coherent patterns of associations with the predictors and outcomes, which suggests their adequate construct validity.

Abstract: Little research has looked at the associations between sex, weight status and culture, and the physical self-perceptions and body dissatisfaction of in iduals with intellectual disabilities (ID) involved in Special Olympics (SO) sports. To examine sex- (male vs female), weight status- (non-overweight/obese vs. overweight/obese), and culture-based (North American vs. Asian) differences in physical self-concept and body dissatisfaction among SO athletes. A total of 139 SO athletes (aged 12-30 years) with ID participated in this study and completed measures of physical self-perceptions and body dissatisfaction. Differences according to sex, weight status, culture, and their interactions were examined. Males SO athletes presented higher levels of self-perceived physical strength and ideal body shape than females. Additionally, non-overweight/obese SO athletes presented higher levels of self-perceived physical appearance and physical condition than their overweight/obese counterparts, as well as lower actual body shape perceptions and body dissatisfaction. Moreover, North-American SO athletes presented higher levels of self-perceived physical appearance and sport competence than their Asians counterparts, as well as lower actual body shapes perceptions and body dissatisfaction. This study reveals substantial sex-, weight status-, and culture-based differences in the physical self-concept and body dissatisfaction of SO athletes.

Abstract: The internal/external frame of reference (I/E) model and dimensional comparison theory posit paradoxical relations between achievement (ACH) and self-concept (SC) in mathematics (M) and verbal (V) domains ACH in each domain positively affects SC in the matching domain (e.g., MACH to MSC) but negatively in the nonmatching domain (e.g., MACH to VSC). This substantive-methodological synergy based on latent variable models of Trends in International Mathematics and Science Study (TIMSS) data supports the generalizability of these predictions in relation to: mathematics and science domains, intrinsic motivation as well as self-concept, and age and nationality, based on nationally representative matched s les of fourth- and eighth-grade students from three Middle Eastern Islamic, five Western, and four Asian countries ( N=117,321 students) with important theoretical, developmental, cross-cultural, and methodological implications.

Abstract: We prospectively tested the extent to which witnessing school violence predicts psychosocial and school adjustment in students while accounting for their prior psychosocial characteristics and peer victimization. We also explored the role of feelings of insecurity in explaining this relationship. Questionnaires were administered to 1104 students (52% boys) from five high schools from the Montreal area (Quebec, Canada) at the beginning, middle, and end of seventh grade. Self report measures included sociodemographic characteristics, victimization, witnessing violence, feelings of insecurity, internalizing and externalizing behavior problems, and measures of engagement, achievement, and truancy as indicators of school adjustment. Witnessing school violence was a comparatively better predictor of subsequent externalizing problems and school adjustment than actual victimization. Conversely, relative to having experienced violence as a witness, actual victimization more reliably estimated later internalizing problems. Feelings of insecurity partially explained the development of school engagement and truancy. Our findings underscore the implications of school violence as a public health and safety issue, the consideration of witnessing as important in estimating its impact, and a comprehensive approach when developing and implementing strategies that aim to prevent this form of community violence.

Abstract: This paper seeks to examine the relationships between affective commitment and organizational citizenship behaviors (OCBs) across four foci: organizations, supervisors, coworkers, and customers. Further, it aims to determine whether relationships among commitments and OCBs involve mediated linkages. This study relies on matched employee‐supervisor data ( n =216). The relative fit of different models representing relationships among commitments and OCBs was examined using structural equations modeling. Results revealed that commitments to coworkers, customers and supervisors displayed positive relationships with OCBs directed at parallel foci. In addition, commitment to the global organization partially and negatively mediated the relationship of commitments to coworkers and customers to parallel OCBs dimensions. Results also revealed cross‐foci relationships between local commitments and OCBs. Finally, no commitment target was significantly associated with organization‐directed OCBs but the latter were positively related to local OCBs. The paper demonstrates that multiple commitments and OCBs are involved in a complex net of relationships among which local foci play a critical, and positive, role.

Abstract: This study aims to: (i) explore the relations between smoking initiation and different profiles of academic achievement trajectories in early to mid-adolescence and (ii) to investigate whether background characteristics (gender, ethnicity, grade repetition, parental education) and proximal processes (parental practices, extra-curricular involvement) predicted class membership and smoking initiation. Four-year longitudinal cohort study (7th-10th grade). Adolescents completed the questionnaires during school hours. At total of 741 adolescents with no history of smoking in grade 7 participating in the Montreal Adolescent Depression Development Project. Self-report questionnaires were used to assess predictors and previous smoking in year 1, and smoking initiation by the end of the study. Grade point average (GPA) was obtained twice yearly from school records. Three academic achievement trajectories were identified and found to differ significantly in rates of smoking initiation: persistently high achievers (7.1% smoking), average achievers (15.1% smokers) and unstable low achievers (49.1% smoking). Further, results showed that general parenting practices and parental education indirectly reduced the likelihood of smoking by reducing the risk of membership in classes with lower GPA. Adolescents who do well in school are less likely to smoke and it may be cost-effective for smoking prevention to focus on the few (12%) easy to identify unstable low achievers who form 35% of smoking onsets. In addition, as parental support and democratic control reduced the likelihood of poor academic performance, promoting essential generic parenting skills from a young age may also prevent future onsets of smoking in adolescence.

Abstract: The involvement of adolescents presenting high levels of social physique anxiety (SPA) in sport practice has been hypothesized as potentially problematic in terms of being associated with disturbed eating attitudes and behaviors (DEAB). Indeed, sport practice itself has been reported to be associated with higher levels of SPA and DEAB, and sport settings may sometimes promote unhealthy life habits. Nevertheless, current studies are few and present several limitations. The objective of the present study was to examine these relationships among adolescents involved or not in various types (i.e., leanness and in idual) and contexts (i.e., organized and competitive) of sport practice. The s le included 766 French adolescents (337 boys and 429 girls), aged between 11 and 18 years, involved (n = 335) or not (n = 431) in sport practice. SPA and DEAB were assessed using French adaptations of the SPA scale and the Eating Attitudes Test-26. The results reveal a significant and positive association between SPA and the DEAB scales. Furthermore, they show a positive relationship between SPA and (a) vomiting-purging behaviors in adolescents involved in in idual sports and (b) generic DEAB (i.e., a subscale covering fear of getting fat, food preoccupation, and eating-related guilt), particularly in adolescents involved in in idual sports. The relationship between SPA and DEAB does not differ according to adolescents' involvement in sport practice or according to their involvement in organized, competitive, or leanness sport practice more specifically. However, higher levels of SPA and DEAB were observed in adolescents involved in in idual sports.

Abstract: The experience s ling method, also referred to as ecological momentary assessment (ESM-EMA) has recently gained popularity in the study of depression. However, no psychometrically sound multidimensional depression questionnaires specifically designed for the ESM-EMA context are currently available. The main objective of the present study was to develop and validate a very short visual analog scale of the Center for Epidemiologic Studies Depression Scales (CES-D-VAS-VS) specifically designed for the ESM-EMA context. To this end, the full French version of the CES-D was adapted for the ESM-EMA context. From this full-length adapted version a very short version was then extracted from this longer instrument and validated. A s le comprising 163 patients with a major depressive episode (MDE) and 306 participants without mental disorders was involved in this study. The obtained results provided support for the factor validity, strong measurement invariance (invariance of the loadings and intercepts of the measurement model) across sex and clinical status groups, reliability and convergent validity of the CES-D-VAS-VS. This instrument comprises 4 items measuring positive affect, depressive affect, somatic complaints and disturbed interpersonal relationships. The present results provide preliminary evidence regarding the construct validity of the CES-D-VAS-VS among patients and community adults s le but also underline the need to rely on latent variables methods in the use of this instrument to account for the differential levels of measurement errors (uniquenessess) that were observed across groups.

Abstract: Very few studies examined the prevalence and sport-related predictors of disturbed eating attitudes and behaviors (DEABs) among adolescents involved in sport practice, and their results are mixed and inconclusive. These inconsistencies are most likely due to their methodological heterogeneity and to the fact that none of these studies took into consideration the potentially relevant characteristics of the sport practice context. This study attempts to answer this limitation among French adolescents not involved or involved in various sports contexts defined based on their organization, leanness-centration, and competitive level. Participants were 335 adolescents involved in sport practice, and 435 adolescents not involved in any form of regular sport practice. The DEABs were measured using the Eating Attitudes Test-26. Global results do not showed any significant association between the status of the participants and DEAB. However, these results drastically changed when we considered the potential moderating role of sex and age on these relations. Indeed, sports involvement in general, and involvement in leanness and competitive sports were found to exert sex- and age-differentiated effects on the risks of presenting clinically significant levels of DEAB. This study suggests the importance of monitoring, preventive, and early intervention mechanisms within the context of practice, particularly for adolescent girls.

Abstract: This substantive-methodological synergy applies evolving approaches to factor analysis to substantively important developmental issues of how five-factor-approach (FFA) personality measures vary with gender, age, and their interaction. Confirmatory factor analyses (CFAs) conducted at the item level often do not support a priori FFA structures, due in part to the overly restrictive assumptions of CFA models. Here we demonstrate that exploratory structural equation modeling (ESEM), an integration of CFA and exploratory factor analysis, overcomes these problems with the 15-item Big Five Inventory administered as part of the nationally representative British Household Panel Study (N = 14,021 age: 15-99 years, Mage = 47.1). ESEM fitted the data substantially better and resulted in much more differentiated (less correlated) factors than did CFA. Methodologically, we extended ESEM (introducing ESEM-within-CFA models and a hybrid of multiple groups and multiple indicators multiple causes models), evaluating full measurement invariance and latent mean differences over age, gender, and their interaction. Substantively the results showed that women had higher latent scores for all Big Five factors except for Openness and that these gender differences were consistent over the entire life span. Substantial nonlinear age effects led to the rejection of the plaster hypothesis and the maturity principle but did support a newly proposed la dolce vita effect in old age. In later years, in iduals become happier (more agreeable and less neurotic), more self-content and self-centered (less extroverted and open), more laid back and satisfied with what they have (less conscientious, open, outgoing and extroverted), and less preoccupied with productivity.

Abstract: The purpose of this study was to test the reliability (i.e. internal consistency and test-retest reliability) and construct validity (i.e. content validity, factor validity, measurement invariance, and latent mean invariance) of the Nutrition and Activity Knowledge Scale (NAKS) in a s le of French adolescents with mild to moderate Intellectual Disability (ID). A total s le of 260 adolescents (144 boys and 116 girls), aged between 12 and 18 years old, with mild to moderate ID was involved in two studies. In the first study, analysis of items' content reveals that many words from the original version were not understood or induced confusion. These items were reworded and simplified while retaining their original meaning. In the second study, results provided support for: (i) the factor validity and reliability of a 15-item French version of the NAKS (ii) the measurement invariance of the resulting NAKS across genders and ID levels (iii) the partial measurement invariance of the resulting NAKS across age groups and type of school placement. In addition, the latent means of the 15-item French version of the NAKS proved to be invariant across gender, age categories, and ID levels, but to vary across type of school placement (with adolescents schooled in self-contained classes from regular schools presenting higher levels of NAK than adolescents placed in specialized establishments). The present results thus provide preliminary evidence regarding the construct validity of a 15-item French version of the NAKS in a s le of adolescents with ID.

Abstract: Research suggests that supervisor expectations regarding the need to respond quickly to work-related messages (SE) tend to be positively related to employees' levels of emotional exhaustion. In the present research paper, the authors examine the indirect – through emotional exhaustion – effects of these expectations on employees' levels of family satisfaction, life satisfaction and sleep quality. They also explore whether and how these associations differ between employees working on-site ( n = 158) or remotely ( n = 284). A total of 442 employees completed an online survey that covered measures on SE, emotional exhaustion, family and life satisfaction and sleep quality. As hypothesized, the results of the study revealed that the indirect effects of SE on family satisfaction, life satisfaction and sleep quality were significantly mediated by emotional exhaustion. Finally, the relations between SE and the mediator (emotional exhaustion) were stronger among employees working on-site than among employees working remotely. SE prevention could be encouraged to decrease employees' emotional exhaustion, in turn increasing their sleep quality, family satisfaction and life satisfaction. These results revealed that working remotely helped buffer the undesirable effects of SE on emotional exhaustion.

Abstract: The Internal-External frame of reference (IE) model suggests that as self-concept in one domain goes up (e.g., English) self-concept in other domains (e.g., mathematics) should go down (ipsative self-concept hypothesis). To our knowledge this assumption has not been tested. Testing this effect also provides a context for illustrating different approaches to the study of growth with longitudinal data. We use cohort sequential data from 2,781 of Year 7 to Year 11 Australian high school students followed across a total of 10 time waves 6 months apart. Three different approaches to testing the ipsative self-concept hypothesis were used: Autoregressive cross-lagged models, latent growth curve models, and autoregressive latent trajectory models (ALT) using achievement as a time varying covariate. Cross-lagged and growth curve models provided little evidence of ipsative relationships between English and math self-concept. However, ALT models suggested that a rise above trend in one self-concept domain resulted in a decline from trend in self-concept in another domain. Implications for self-concept theory, interventions, and statistical methods for the study of growth are discussed.

Abstract: This study proposes a revision (R) of the Center for Epidemiologic Studies Depression Scale for youth with ID (CESD-ID) in English and French. 346 youth (36.02% girls) with mild (51.26%) and moderate (48.78%) ID (11-22 years M = 15.69), enrolled in secondary schools in Canada (French-speaking n = 115), and Australia (English-speaking n = 231), as well as their parents and teachers, participated in this study. Results support the reliability, factor validity, equivalence (sex, ID level, comorbidities, and country), and convergent validity (with youth-, parent-, and teacher-rated measures of depression, anxiety, and loneliness/social isolation) of the CESD-ID-R. The CESD-ID-R allows youth with ID to provide a reliable and valid assessment of their depressive mood and happiness suitable for epidemiological studies.

Abstract: This study investigates heterogeneity in adolescents' trajectories of global self-esteem (GSE) and the relations between these trajectories and facets of the interpersonal, organizational, and instructional components of students' school life. Methodologically, this study illustrates the use of growth mixture analyses, and how to obtain proper student-level effects when there are multiple schools, but not enough to support multilevel analyses. This study is based on a 4-year, six-measurement-point, follow-up of 1,008 adolescents (M(age) = 12.6 years, SD = 0.6 at Time 1.) The results show four latent classes presenting elevated, moderate, increasing, and low trajectories defined based on GSE levels and fluctuations. The results show that GSE becomes trait-like as it increases and that school life effects, moderated by gender, played an important role in predicting membership in these trajectories.

Puis, une seconde étude a été réalisée auprès de deux échantillons distincts (N = 222, N = 248) afin de confirmer la structure factorielle de l’instrument et de vérifier sa validité nomologique. Les résultats indiquent que l’instrument francophone présente une structure factorielle conforme à la conceptualisation de Spreitzer (1995 ) et que la mesure est liée à des antécédents et des conséquences faisant partie de son réseau nomologique.

Abstract: This study evaluated the nature of the life satisfaction construct with an emphasis on the comparison between a global or domain-specific operationalization during the transition from adolescence to adulthood. A combination of person-centered and variable-centered methods were used to analyze 7 waves of data covering the postschool transition from a s le of 24,721 youth participating in Longitudinal Study of Australian Youth (LSAY) between 1998 and 2010. Evidence for the increasing importance of a domain-specific approach as adolescents entered adulthood was provided by: (1) factor analyses identifying a 3-factor model covering achievement, family, and leisure satisfaction that proved invariant across time waves (2) factor mixture analyses showing shape-related differences between profiles (i.e., within-profile differences between domains) that increased as young people moved into adulthood.

Abstract: The present research proposes an improved understanding of work motivation by identifying employees’ motivational profiles while taking into account the dual global and specific nature of work motivation proposed by self‐determination theory (SDT). To document the construct validity of these latent profiles, we relied on the circumplex model of employees’ well‐being to investigate whether they differed in terms of burnout, work satisfaction, and work addiction. Results from analyses conducted among a s le of 955 employees revealed five distinct profiles characterized by differing levels of global and specific forms of motivation: Intrinsically Motivated, Poorly Motivated, Driven, Conflicted, and Self‐Determined. Lower levels of burnout and work satisfaction were associated with profiles characterized by higher global levels of self‐determination and more autonomous forms of motivation, matching theoretical expectations. Interestingly, work addiction was highest in the Driven profile and lowest in the Self‐Determined profile, suggesting that autonomous forms of motivation are not always able to buffer the adverse effects of controlled forms of motivation. Our results also suggest that the specific qualities of work motivations are just as important as the global levels of self‐determination in the identification of work motivation profiles.

Abstract: To develop and validate a fast dynamic MR imaging scheme. A novel approach termed K-T ARTificial Sparsity enhanced GROWL (K-T ARTS-GROWL) is proposed that integrates dynamic artificial sparsity and GROWL-based parallel imaging (PI). Golden-angle radial k-space data are acquired with the free-breathing s ling scheme and then sorted into a time series by grouping consecutive spokes into temporal frames. The reconstruction framework sequentially applies PI and dynamic artificial sparsity. In the implementation, GROWL is taken as a special PI instance for its high computational efficiency and the K-T sparse is exploited to improve the PI reconstruction performance, because the dynamic MR images are often sparse in the x-f domain. In the final reconstruction procedure, artificial sparsity is constructed and fed back to the previous reconstruction. The K-T ARTS-GROWL results in high spatial and temporal resolution reconstructions. By exploiting dynamic artificial sparsity, the acceleration capability is further improved compared to the PI alone. The experimental results demonstrate that K-T ARTS-GROWL leads to significantly better image quality (P < 0.05) than the frame-by-frame GROWL and frame-by-frame ARTS-GROWL for in vivo liver imaging. Compared with the tested K-T reconstruction algorithms, the K-T ARTS-GROWL results in a better or comparable image quality and temporal resolution with greatly decreased computational costs. The proposed technique enables sparse, fast imaging of high spatial, high temporal resolutions for dynamic MRI.

Abstract: The present study examined the configurations, or profiles, taken by distinct global and specific facets of job engagement and burnout (by relying on a bifactor operationalization of these constructs) among a nationally representative s le of Canadian Defence employees ( n = 13,088 nested within 65 work units). The present study also adopted a multilevel perspective to investigate the role of job demands (work overload and role ambiguity), as well as in idual (psychological empowerment), workgroup (interpersonal justice), supervisor (transformational leadership), and organizational (organizational support) resources in the prediction of profile membership. Latent profile analyses revealed five profiles of employees: Burned-Out/Disengaged (7.13%) , Burned-Out/Involved (12.13%), Engaged (18.14%), Engaged/Exhausted (15.50%), and Normative (47.10%). The highest turnover intentions were observed in the Burned-Out/Disengaged profile, and the lowest in the Engaged profile. Employees’ perceptions of job demands and resources were also associated with profile membership across both levels, although the effects of psychological empowerment were more pronounced than the effects of job demands and resources related to the workgroup, supervisor, and organization. In idual-level effects were also more pronounced than effects occurring at the work unit level, where shared perceptions of work overload and organizational support proved to be the key shared drivers of profile membership.

Abstract: Among the few instruments used to measure the behavioral component of body image disturbances, the Body Image Avoidance Questionnaire (BIAQ) is the most widely used. Despite the wide utilization of this instrument, it is currently unknown whether it is appropriate for male and female adolescents from middle and junior high schools. The main objective of the present series of studies was to test the construct validity of the BIAQ in a community s le of French adolescents. The content, factor, and convergent validity of the BIAQ were verified in the context of four independent studies conducted on a total s le of 945 adolescents. The first study showed that the content and formulation of the French BIAQ items were adequate for children and adolescents. The following three studies provided support for the factor validity, measurement invariance (across sex), reliability, and convergent validity of the French BIAQ. Regarding the measurement invariance tests, the results revealed that the models were invariant up to the levels of the latent means structures. Post hoc probing of these differences showed a significant higher latent mean score of the global BIAQ scale in females (in s les 2 and 3). The present results provide preliminary evidence regarding the construct validity of the BIAQ in a community s le of French adolescents.

Abstract: The purpose of this paper is to extend past research by investigating the relationships between supervisors' empowering management practices (SEMP), employees' psychological empowerment (PE), and a new measure of employees' behavioral empowerment (BE). A mediation model is hypothesized. A questionnaire study is conducted among 359 non‐managerial employees. Because BE is both self‐reported and externally assessed, relationships are verified with single‐source and multi‐source data. SEMP are quite strongly related to PE, but more weakly related to BE. Structural equation analyses tend to support a model where PE completely mediates the relationship between supervisors' managerial practices and employees' BE. This cross‐sectional study does not provide indication of causality among the variables. First, this paper suggests that feeling empowered is a pivotal mindset that needs to be created by supervisors to generate proactive behaviors. Second, the moderate correlation found between PE and BE measures suggests that they capture different facets of empowerment. Given management concern for bottom line results, behavioral measures should not be ignored in assessing employee empowerment. This paper used a behavioral criterion to assess employee empowerment rather than relying solely on a psychological measure.

Abstract: The passion scale, based on the dualistic model of passion, measures 2 distinct types of passion: Harmonious and obsessive passions are predictive of adaptive and less adaptive outcomes, respectively. In a substantive-methodological synergy, we evaluate the construct validity (factor structure, reliability, convergent and discriminant validity) of Passion Scale responses (N = 3,571). The exploratory structural equation model fit to the data was substantially better than the confirmatory factor analysis solution, and resulted in better differentiated (less correlated) factors. Results from a 13-model taxonomy of measurement invariance supported complete invariance (factor loadings, factor correlations, item uniquenesses, item intercepts, and latent means) over language (French vs. English the instrument was originally devised in French, then translated into English) and gender. Strong measurement partial invariance over 5 passion activity groups (leisure, sport, social, work, education) indicates that the same set of items is appropriate for assessing passion across a wide variety of activities--a previously untested, implicit assumption that greatly enhances practical utility. Support was found for the convergent and discriminant validity of the harmonious and obsessive passion scales, based on a set of validity correlates: life satisfaction, rumination, conflict, time investment, activity liking and valuation, and perceiving the activity as a passion.

Abstract: Self-esteem and body image are central to coping successfully with the developmental challenges of adolescence. However, the current knowledge surrounding self-esteem and body image is fraught with controversy. This study attempts to clarify some of them by addressing three questions: (1) Are the intrain idual developmental trajectories of self-esteem and body image stable across adolescence? (2) What is the direction of the relations between body image and self-esteem over time? (3) What is the role of gender, ethnicity, and pubertal development on those trajectories? This study relies on Autoregressive Latent Trajectory analyses based on data from a 4-year, 6-wave, prospective longitudinal study of 1,001 adolescents. Self-esteem and body image levels remained high and stable over time, although body image levels also tended to increase slightly. The results show that levels of self-esteem were positively influenced by levels of body image. However, these effects remained small and most of the observed associations were cross-sectional. Finally, the effects of pubertal development on body image and self-esteem levels were mostly limited to non-Caucasian females who appeared to benefit from more advanced pubertal development. Conversely, Caucasian females presented the lowest self-esteem and body image levels of all, although for them more advanced pubertal development levels were associated with a slight rise in body image over time.

Abstract: This research relies on a combination of variable‐ and person‐centered approaches to improve our understanding of the dimensionality of work engagement and burnout. Among 1004 teachers who completed a questionnaire twice over an eight‐month period, our results first revealed that work engagement and burnout ratings simultaneously reflected two global overarching constructs co‐existing with six specific dimensions (vigor, dedication, and absorption as well as emotional exhaustion, cynicism, and professional efficacy). We then examined the profiles taken by these global and specific dimensions, documented their stability and interrelations over time, and tested their associations with theoretically relevant predictors. Three work engagement (Vigorously Engaged, Disengaged, Engaged) and three burnout (Burned‐Out, Adapted, Normative) profiles were identified. Most Disengaged teachers at Time 1 corresponded to the Burned‐Out profile at Time 2, and most Burned‐Out teachers at Time 1 corresponded to the Disengaged profile at Time 2. Workload perceptions increased teachers' likelihood of membership into the Disengaged profile relative to the Engaged one. In contrast, most job resources perceptions (control, rewards, and values) predicted an increased likelihood of membership into the Engaged profile relative to the Disengaged one.

Abstract: The present study examined (a) whether groups of children can be empirically identified with distinct longitudinal profiles of depressed mood from late childhood through early adolescence, (b) to what extent these different longitudinal depression profiles are predicted by problematic relations with parents, same-sex peers, and other-sex peers, and (c) what role in iduals' temperamental characteristics play in this context. Based on a s le of 414 early adolescents (197 girls), four groups were identified with distinct longitudinal profiles of depressed mood between ages 11 and 14: One group with consistently low levels of depressed mood, another with consistently moderate levels of depressed mood, a third group whose depressed mood increased sharply from late childhood through early adolescence, and a fourth group who already showed clinical-range levels of depressed mood during late childhood and whose depressive feelings increased even slightly more thereafter. Subsequent analyses revealed that rejection by same-sex peers was related to the odds of following an increasing trajectory of depressed mood, but only for girls with a highly reactive temperament. A problematic relationship with parents increased the odds of an elevated trajectory of depressed mood regardless of in idual temperament. The theoretical and practical implications of these findings are discussed.

Abstract: The association between cognitive training and exercise motivation remains unclear, particularly when the training is not explicitly focused on modifying goal content. Our study investigated the impact of such training on exercise-related decision-making skills among a s le of low-active adults (N = 233 Mage = 46.7 years) who completed the Exercise Motivation Inventory-2 (EMI2) at baseline and one-month follow-up. Latent profile analyses (LPA) were used to identify participants’ motivational profiles at each time point, and longitudinal tests of profile similarity and latent transition analyses (LTA) assessed the replicability of these profiles and the stability of participants’ profile membership over time. Our results revealed four profiles, which were replicated over time: Weakly Motivated, Moderately Motivated with Fitness Orientation, Moderately Motivated with Psychological Well-being Orientation, and Strongly Motivated. Membership to these profiles was not influenced by participants demographic characteristics, and only minimally by baseline Fitbit steps and cardiorespiratory fitness. The first two profiles displayed fewer months (over a period of 12 months post-intervention) meeting physical activity guidelines, whereas the latter two showed higher levels of adherence. The Strongly Motivated profile was the least stable but most influenced by the cognitive training intervention, whereas the Moderately Motivated with Fitness Orientation was more stable but similarly influenced by the intervention. These findings highlight the potential of a multimodal cognitive training in influencing exercise motivation and behavior, providing practical implications for tailoring interventions to specific motivational profiles. Future research should investigate the specific types of cognitive training most effective for enhancing exercise motivation and adherence.

Abstract: Although one of the central premises of authentic leadership theory is that authentic leaders mobilize their followers, the underlying motivational mechanisms of this process remain poorly understood. Drawing on self-determination theory, this study aims to fill that gap by examining authentic leadership practices (ALP) as theoretical antecedents of employees' motivation profiles. Latent profile analyses conducted on a s le of 501 employees revealed four profiles: self-determined, unmotivated, highly motivated and moderately motivated. ALP were associated with a higher likelihood of membership into the most adaptive motivation profiles. Employees in these profiles displayed more optimal job functioning: higher organizational commitment and performance, and lower intentions to leave their organization. These findings underscore the predictive power of autonomous motivation for employee functioning and provide new insights into how ALP can improve work motivation, and hence job functioning. Our results account not only for how ALP affects the complete range of behavioral regulations at work but also the different patterns in which these regulations combine within employees.

Abstract: Although le research has documented the implications, and organizational drivers, of leadership behaviors, very little research has considered these associations, and their consequences, from the perspective of managers. The present four‐wave longitudinal study addresses this limitation by focusing, using the Job Demands‐Resources model, on the work‐related drivers (job control, recognition, and workload) of transformational, transactional and laissez‐faire leadership behaviors, and the associations between these behaviors and manifestations of managers' psychological well‐being at work (job satisfaction, burnout, and turnover intentions). Analyzing data from 691 high‐level managers (i.e. school principals) using novel random intercept cross‐lagged panel model analyses, our results revealed that higher levels of job control and recognition, and lower levels of workload, predicted higher levels of transformational and transactional leadership behaviors. In contrast, laissez‐faire leadership behaviors were only negatively predicted by recognition. Transformational leadership was associated with the most desirable outcome levels (higher levels of job satisfaction, lower levels of turnover intentions and burnout), followed by transactional and laissez‐faire leadership. Most of these associations were limited to the between‐person‐level, reflecting stable mechanisms of influence, rather than at the within‐person level, suggesting the presence of homeostatic mechanism helping high levels managers to maintain a stable level of functioning over time.

Abstract: To validate a version of the Motives for Physical Activity Measure (MPAM) adapted for youth with intellectual disabilities (ID). A s le of 359 youth with mild to moderate ID from Australia and Canada respectively completed English and French versions of the MPAM-ID. Exploratory structural equation models supported the validity and reliability of the five-factor structure of the MPAM-ID, as well as the weak, latent variance-covariance, and latent mean invariance across linguistic versions. Additional results supported the partial strong and strict invariance of most MPAM-ID items across linguistic versions. The results also supported the complete measurement invariance of the MPAM-ID over time and revealed a lack of differential item functioning (DIF) as a function of youth's age, body-mass index (BMI), ID level, and frequency of sport involvement (FSI). However, partial DIF was found as a function of youth's sex. Additionally, latent mean differences in MPAM-ID's factors were found as a function of youth's ID level, sex, and FSI. Finally, results supported the convergent validity of the MPAM-ID factors with a measure of perceived physical abilities. The MPAM-ID can be used among English- and French-speaking youth with ID irrespective of their age, BMI, ID level, sex, and FSI.IMPLICATIONS FOR REHABILITATIONWe propose English and French adaptations of the Motives for Physical Activity Measure for Youth with Intellectual Disabilities (MPAM-ID).The MPAM-ID was able to identify the same motives as the original measure.The MPAM-ID will facilitate the assessment of motives for physical Activity in cross-sectional and longitudinal studies.The MPAM-ID will facilitate the assessment of motives for physical Activity among English- and French-speaking youth with ID.The MPAM-ID could be used to compare youth motives for physical Activity as a function of their age, body-mass index, ID level, and frequency of sport involvement.

Abstract: (This study examines the directionality of the associations among cognitive assets (IQ, academic achievement), motivational beliefs (academic self-concept, task values), and educational and occupational aspirations over time from late adolescence (Grade 10) into early adulthood (5 years post high school). Participants were from a nationally representative s le of U.S. boys N = 2,213). The results suggest that (a) self-concept and intrinsic value have reciprocal effects with academic achievement and predict educational attainment, (b) self-concept is consistently found to predict occupational aspirations, (c) the associations between achievement and aspirations are partially mediated by motivational beliefs, and (d) academic self-concept in high school had stronger long-term indirect effects on future occupational aspirations and educational attainment than task values and IQ.

Abstract: To improve the performance of non-Cartesian partially parallel imaging (PPI) by exploiting artificial sparsity, the generalized autocalibrating partially parallel acquisitions (GRAPPA) operator for wider band lines (GROWL) is taken as a specific ex le for explanation. This work is based on the GRAPPA-like PPI having an improved performance when the to-be-reconstructed image is sparse in the image domain. A systematic scheme is proposed to artificially generate the sparse image for non-Cartesian trajectory. Using GROWL as a specific non-Cartesian PPI method, artificial sparsity-enhanced GROWL (ARTS-GROWL) is used to demonstrate the efficiency of the proposed scheme. The ARTS-GROWL consists of three steps: 1) generating synthetic k-space data corresponding to an image with smaller support, that is, artificial sparsity 2) applying GROWL to the synthetic k-space data from previous step and 3) recovering the final image from the reconstruction with the processed data. For simulation and in vivo data, the experiments demonstrate that the proposed ARTS-GROWL significantly reduces the reconstruction errors compared with the conventional GROWL technique for the tested acceleration factors. Taking ARTS-GROWL, for instance, experimental results indicate that artificial sparsity improved the signal-to-noise ratio and normalized root-mean-square error of non-Cartesian PPI.

This instrument was renamed CES-D for ID (CES-D-ID) and two different versions based on two alternative answer scales (Likert and Likert-graphical) were developed and their psychometric properties were verified in study 2. The results provided support for the factor validity, reliability and invariance across gender and age of a 14-item version of the CES-D-ID based on a Likert-graphical answer scale.

Abstract: In a recent review of various physical self-concept instruments, Marsh and Cheng (in press) noted that the very short 12-item version of the French Physical Self-Inventory (PSI-VS) represents an important contribution to applied research but that further research was needed to investigate the robustness of its psychometric properties in new and ersified s les. The present study was designed to answer these questions based on a s le of 1103 normally achieving French adolescents. The results show that the PSI-VS measurement model is quite robust and fully invariant across subgroups of students formed according to gender, weight, age and ethnicity. The results also confirm the convergent validity and scale score reliability of the PSI-VS subscales.

Abstract: The fear of childbirth, a central aspect of tokophobia, recently started to capture the attention of the scientific community as a potential determinant of obstetric and post-natal complications. However, studies on this subject are still few and this can be partly explained by the lack of validated instruments, especially in French. This paper presents the results from two studies designed to develop and evaluate the psychometric properties of a French version of the Traumatic Event Scale (TES), adapted to assess fear of childbirth (Söderquist et al., 2004 [21]). The first study presents details regarding the development of this scale and checks the quality of the resulting items as well as their internal consistency, convergent validity and factorial validity. This study relied on a s le of 65 mothers with at least one child under the age of 36 months. In the second study, the psychometric properties of the instrument developed in Study 1 were tested more systematically on a s le of 204 women who were at the time experiencing their first pregnancy. The results from the first study show adequate psychometric properties, strong correlations with measurements assessing worry, and support a five factor model. Results from this second study replicated the results from the first one on the basis of confirmatory factor analyses. Findings presented in these studies confirm that this instrument presents very good psychometric properties as a measurement of the fear of childbirth in pregnant women.

Abstract: This research examines how employee’s perceptions of three sources of support in the workplace (i.e., organization, supervisor, and colleagues) combine within specific profiles and the nature of the relations between these profiles and indicators of employees’ psychological health (i.e., stress, sleep problems, psychosomatic strains, and depression). Furthermore, this research examines the within-s le and within-person stability of the identified support profiles over the course of an 8-month time interval. Latent profile and latent transition analyses conducted on a s le of 729 workers indicated six identical profiles across the two measurement occasions: 1, moderately supported 2, weakly supported 3, isolated 4, well-supported 5, supervisor supported and 6, highly supported. Profile membership was very stable over time for most profiles, with the exception of the isolated profile which was only moderately stable. Furthermore, the isolated and supervisor-supported profiles presented the lowest levels of psychological health, while the well-supported and moderately supported profiles presented the highest levels of psychological health. Of particular interest, results suggested that some risks might be associated with the highly supported profile, although this result could be a simple reflection of the women-dominant composition of this profile. This research has implications for theory and practice, which will be discussed in the article.

Abstract: NEO instruments are widely used to assess Big Five personality factors, but confirmatory factor analyses (CFAs) conducted at the item level do not support their a priori structure due, in part, to the overly restrictive CFA assumptions. We demonstrate that exploratory structural equation modeling (ESEM), an integration of CFA and exploratory factor analysis (EFA), overcomes these problems with responses (N = 3,390) to the 60-item NEO-Five-Factor Inventory: (a) ESEM fits the data better and results in substantially more differentiated (less correlated) factors than does CFA (b) tests of gender invariance with the 13-model ESEM taxonomy of full measurement invariance of factor loadings, factor variances-covariances, item uniquenesses, correlated uniquenesses, item intercepts, differential item functioning, and latent means show that women score higher on all NEO Big Five factors (c) longitudinal analyses support measurement invariance over time and the maturity principle (decreases in Neuroticism and increases in Agreeableness, Openness, and Conscientiousness). Using ESEM, we addressed substantively important questions with broad applicability to personality research that could not be appropriately addressed with the traditional approaches of either EFA or CFA.

Abstract: This substantive-methodological synergy applies mixture modeling to verify whether the elusive, yet widely endorsed, actual-ideal discrepancy (AID) model might be verified in specific subgroups. Relations between Actual and Ideal Appearance, Physical Self-Concept (PSC), and Global Self-Esteem (GSE) were assessed with Mixture Structural Equation Models in a large s le of youth (N = 1,693). The results revealed three profiles, one of which (25.7%) supported the predicted negative effect of Ideal Appearance on PSC. The relations seem to be more complex than assumed, such that the effects of Actual Appearance on PSC/GSE increase as ideal standards increase, and that the negative effects of ideal standards on PSC are only apparent when these standards are lower. These results suggest the need for a revised AID model where ideals play a weighting role in the relations between Actual Appearance, PSC, and GSE.

Abstract: This substantive-methodological synergy demonstrates evolving multilevel latent-variable models for cross-cultural data. Using Trends in International Mathematics and Science Study (TIMSS) 2007 data for U.S. and Saudi Arabian eighth grade students, we evaluate the psychometric properties (measurement invariance, method effects, and gender differences) of math self-concept, positive affect, coursework aspirations, and achievement. Extending the studies of the “paradoxical cross-cultural self-concept effect” largely based on U.S.-Asian comparisons, country-level differences strongly favored the United States for achievement test scores, but favored Saudi Arabia for self-concept and aspirations. Latent mean gender differences, of particular interest because of Saudi Arabia’s single-sex school system, interacted with country for all constructs. The largest interaction was for achievement test scores there were no significant gender differences for U.S. students (in coed schools), but in single-sex Saudi schools, Saudi girls performed substantially better than Saudi boys. Consistently with previous (mostly Western) research, but not previously evaluated with TIMSS, in each of the four (2 gender × 2 country) groups all three outcomes (self-concept, affect, and aspiration) were positively influenced by in idual student achievement but negatively influenced by class-average achievement (the Big-Fish-Little-Pond Effect: BFLPE). BFLPEs were similar in size for boys and girls in coeducational (United States) and in single-sex (Saudi) classrooms.

Abstract: This study examined the profiles taken by global and specific facets of work engagement and burnout among a s le of novice ( M tenure = 3.77 years) nurses ( n = 570 88.4% females M age = 29.3 years). This study also investigated the role of psychological need satisfaction in the prediction of profile membership, and the implications of these profiles for attitudinal (job satisfaction), behavioral (in-role and extra-role performance, absenteeism, and presenteeism) and health (perceived health difficulties) outcomes. Latent profile analyses revealed six profiles: High Global Engagement and Low Global Burnout, Moderately High Global Engagement and Moderately Low Global Burnout, Low Dedication and Efficacy and Highly Cynical, Dedicated but Exhausted Burned-Out, Low Efficacy Burned-Out, and Very Low Global Engagement and Very High Global Burnout. Although these profiles were replicated over a 1-year period, profile membership was only weakly stable. The most beneficial outcomes were observed in the High Global Engagement and Low Global Burnout profile, and the most detrimental in the Very Low Global Engagement and Very High Global Burnout profile. Need satisfaction was also associated with profile membership, although associations were stronger for global levels of need satisfaction than for specific levels of autonomy, competence, and relatedness need satisfaction.

Abstract: This research relies on a combination of variable- and person-centered approaches to help improve our understanding of the dimensionality of the workaholism construct. Our results showed that employees’ workaholism ratings simultaneously reflected a global overarching construct co-existing with four specific dimensions (behavioral, motivational, emotional, and cognitive workaholism) among a s le of 432 workers who completed a questionnaire twice over a three-month period. We also examined the profiles taken by workaholism dimensions, and documented their stability over time as well as the associations between these profiles and theoretically-relevant predictors and outcomes. Furthermore, we examined whether these associations differ as a function of working remotely or onsite. Four profiles were identified and found to be highly stable over time: Unplugged, Plugged In, Moderately Unplugged with Externalized Workaholism, and Moderately Unplugged with Cognitive Workaholism. Personal life orientation, telepressure, and interpersonal norms regarding work-related messages were related to the likelihood of profile membership. Remote working also reinforced the positive effects of personal life orientation and the negative effects of interpersonal norms regarding work-related messages. Finally, employees’ work-to-family guilt, job satisfaction, family satisfaction, and life satisfaction also differed as a function of their profile.

Abstract: The 2011 Organizational Research Methods Feature Topic on latent class procedures has helped to establish person-centered analyses as a method of choice in the organizational sciences. This establishment has contributed to the generation of substantive-methodological synergies leading to a better understanding of a variety of organizational phenomena and to an improvement in research methodologies. The present Feature Topic aims to provide a user-friendly introduction to these new methodological developments for applied organizational researchers. Organized around a presentation of the typological, prototypical, and methodologically exploratory nature of person-centered analyses, this introductory article introduces seven contributions aiming to: (a) clarify the meaning, advantages, and applications of person-centered analyses (b) illustrate emerging prototypical and longitudinal cluster analytic approaches (c) introduce researchers to multilevel person-centered analyses as well as to auxiliary approaches that will drastically increase the scope of application of these methods and (d) describe the application of these methods for confirmatory purposes.

Abstract: The management of COPD aims to improve integrated indices such as health-related quality of life (HRQoL). Experts recommend repeated and methodical assessment of HRQoL, particularly by the use of questionnaires. Though these tools give pertinent information for groups of patients, they have limitations in describing the progress in one patient or indicating the prognosis. The purpose of this study is to validate a brief, self-administered HRQoL questionnaire, designed for the in idual follow-up of COPD patients over a period of 3-6 months. Following an initial validation of the contents and a review of the literature, 166 COPD patients completed an experimental version of a questionnaire including 24 items, three theoretical components (functional, psychological and relational) and 11 sub-dimensions. Confirmative factor analyses show a hierarchical model in respect of the current criteria (chi(2)=62.042 dl=41 ratio chi(2)/ddl=1.51 p<0.02 CFI=0.955 TLI=0.939 RMSEA=0.056 SRMR=0.054) composed of 11 items (one by a theoretical sub-dimension) distributed in three components (functional=3 psychological=4 relational=4). The questionnaire obtained, named VQ11, possesses an internal validation which satisfies international psychometric standards. It remains necessary to demonstrate whether the questionnaire satisfies the criteria of external validation and that it reveals thresholds of clinical change.

Abstract: Universities faced important and sudden changes following the lockdown measures imposed during the COVID‐19 pandemic. Traditional educational practices were disrupted as c uses were closed while distance learning was hastily adopted. This study documents the evolution of university students' autonomous and controlled motivation for their studies following c us closures by relying on a person‐centred perspective. More specifically, it examines motivation profiles and their temporal stability across two time points taken before and during the pandemic, while also considering the role of educational climate, trait self‐control and control variables (sex and age) as predictors of profile membership. A total of 1940 university students participated in this study by responding to online questionnaires at two time points, before (Time 1) and after (Time 2) the pandemic. We relied on latent profile and latent transition analyses to estimate motivation profiles, their temporal stability and their predictors. A four‐profile solution ( Self‐Determined, Moderately Motivated , Extrinsically Motivated , Amotivated ) was selected and replicated at both time points. We observed a low degree of variability in profile membership over time, especially for the Amotivated profile. A need‐supportive educational climate and trait self‐control consistently predicted a greater likelihood of membership into more adaptative profiles ( Self‐Determined, Moderately Motivated ). The COVID‐19 pandemic did not drastically change the motivational profiles of university students. Nevertheless, educational climate and self‐control appeared to ‘protect’ students against the endorsement of more problematic motivation profiles both before and during the pandemic, making them important targets for intervention.
