Abstract: Early interventions for depression among youth are greatly needed. Although Youth Mental Health First Aid (YMHFA) program has been developed to teach the public how to help young people with mental disorders, including depression, it has assumed human altruism and overlooked the possibility that participants would experience conflict between the costs and benefits of helping behaviors. The present qualitative study, therefore, initially explored content of the costs and benefits perceived by youth in terms of helping their peers with depression. A total of 56 Japanese undergraduates (32 female, 24 male M age = 20.20, SD = 1.09) participated in the face-to-face survey. They were provided with basic knowledge about helping behaviors and were presented with a vignette describing an undergraduate with depression. Then, they left free descriptive comments on their views of the costs/benefits of helping/not helping the person in the vignette. As supplemental quantitative analyses, we statistically compared numbers of labels ( n = 624), which were obtained from participants’ comments, across two (costs/benefits) × two (helping/not helping) domains. Finally, we conducted a qualitative content analysis that combined inductive and deductive methods to categorize these labels. The supplemental quantitative analyses (i.e., ANOVA and post hoc analyses) on the numbers of labels highlighted that the participants perceived suppressors (i.e., costs of helping , benefits of not helping ) as well as motivators (i.e., costs of not helping ) in making decision to help peers with depression. The qualitative content analysis mainly showed that: (i) the categories in each domain covered multiple facets of costs and benefits, including negative ositive effects on the participants themselves, the person in the vignette, and interpersonal relationships and that (ii) the participants perceived the conflicts of costs and benefits regardless of whether they help their peers with depression. These results provide evidence for how young people experience the conflicts between the costs and benefits of helping behaviors toward their peers with depression and reveal specific content of these costs and benefits. These findings could serve as a basis for extending YMHFA programs and designing educational content to promote public helping behaviors in realistic situations.

Abstract: Several training programs and forums for mental health peer support have been developed, and perceptions of costs and benefits affecting peer supporters' helping behaviors have been investigated. To investigate the most efficient ways to motivate people to provide mental health peer support, we conducted a series of cross‐sectional network analyses that (a) visualized the network structures of the perceived costs and benefits of helping or not helping peers with depression and (b) identified the most central component in each network. Participants were 297 Japanese undergraduates (mean age = 19.27 years) who rated how much they cared about items related to the costs/benefits of helping/not helping using a Likert scale. A series of psychological networks consisting of nodes (components) connected by edges (regularized partial correlations) were estimated, and the most central component judged on the basis of high scores for strength, closeness, and betweenness indexes was identified in each network (e.g., “loss of energy” in the Costs of Helping network). Discussion focuses on these identified central components as targets for intervention within the larger networks of perceived costs and benefits.

Abstract: The psychological network approach, which conceptualizes mental disorders as complex systems and provides a statistical toolbox to estimate symptom networks, has evoked innovations in psychopathology research. This perspective paper discusses how to implement this approach in real-world clinical settings, emphasizing that clinical scientists should motivate clinicians and clients to utilize it. To promote the clinical use of the psychological network approach, we provide the following five steps clinical scientists should undertake: i) provide clinicians and clients with the necessary background knowledge, ii) encourage clinicians to use the narrative network models, iii) provide clinicians with user-friendly mobile apps to conduct empirical network analyses, iv) explore clients’ experiences during the pilot trials using the psychological network approach, and v) develop guidelines for interventions using the psychological network approach through the collaboration of clinical scientists, clinicians, and clients. We close the paper by discussing the importance of bridging the academic field and clinical settings, in the hopes that other clinical scientists will participate in the discussion of possible futures for the psychological network approach.

Abstract: The present studies examined what kinds of beliefs are typically held about people with depression based on data from s les of Japanese university students. Study 1a utilized text describing people with depression that was ided into categories, and examined which categories were most frequently described. In Study 1b, participants rated how much they agreed with the beliefs categorized in Study 1a. A similar approach was taken in Study 2a (qualitative) and 2b (quantitative), in order to examine prototypic negative beliefs. Results from Study 1a and 1b indicated that prototypic beliefs were the "serious and working too hard" belief in regard to characteristics of people with depression, and the "taking too much things on oneself" belief related to personal responsibility. Results from 2a and 2b indicated that prototypic negative beliefs were the "gloomy" belief in regard to characteristics of people with depression, and the "mental weakness" belief related to personal responsibility. Implications for research on stigma toward people with depression are discussed.

Abstract: Stigmatizing beliefs about depression have been viewed as a barrier to seeking professional treatments. To reconsider frameworks used in previous research, the present study utilized Brief Implicit Association Tests (BIATs) and examined the following two topics: (i) whether participants tend to hold dangerous beliefs about depression, and (ii) whether stigmatizing beliefs can be reduced through education. Japanese university students (48 women, 82 men M age = 20.2yr.) voluntarily participated in the study and were randomly assigned to three conditions in which they received different educational texts (biomedical, psychosocial, and bio-psychosocial). Participants completed repeated assessments (baseline, post-education, and 4-wk. follow-up), in which they were administered BIATs measuring beliefs about being weak-willed and dangerousness of people with depression, along with explicit measures of blameworthiness, dangerous beliefs, and of other related variables. BIATs at baseline indicated that the participants did not tend to hold the belief about dangerousness. There was no significant reduction of beliefs about being weak-willed and dangerousness of people with depression, which were measured by BIATs, after reading the educational texts.

Abstract: Depression is a heterogeneous disorder that has various subtypes. In Japan, however, a prevailing misunderstanding is that the term utsu-byo (clinical depression) indicates only the melancholic type. Consequently, a subtype called 'modern-type depression' (MTD), which has contrasting features to those of melancholic or traditional-type depression (TTD), is severely stigmatized in Japan these days. The present study conducted a cross-cultural comparison of perceptions of TTD and MTD between Japan and the USA to examine how the Japanese collectivistic culture contributes to negative biases toward MTD. Undergraduate students in Japan (N = 303) and the Midwestern USA (N = 272) completed the survey. They read two vignettes that described the conditions of fictional in iduals with either TTD or MTD, and then reported their perceptions of each vignette. Mixed analyses of variance revealed significant interactions between nation (Japan or the USA) and vignette (TTD or MTD) on most perception items. These interactions and subsequent analyses with Bonferroni corrections mainly indicate the following: (i) Japanese are more likely to suppose that conditions of MTD are milder compared with TTD and (ii) Japanese are more likely to hold stronger aversive attitudes and weaker willingness to provide support toward people with MTD than toward those with TTD. These results indicate that people with MTD are more likely to be accepted in the US independent culture than in the Japanese collectivistic culture. Discussion highlights that cultural ersity education potentially reduces stigma of MTD in Japan.

Abstract: Patients with mental disorders often suffer from comorbidity. Transdiagnostic understandings of mental disorders are expected to provide more accurate and detailed descriptions of psychopathology and be helpful in developing efficient treatments. Although conventional clustering techniques, such as latent profile analysis, are useful for the taxonomy of psychopathology, they provide little implications for targeting specific symptoms in each cluster. To overcome these limitations, we introduced Gaussian graphical mixture model (GGMM)-based clustering, a method developed in mathematical statistics to integrate clustering and network statistical approaches. To illustrate the technical details and clinical utility of the analysis, we applied GGMM-based clustering to a Japanese s le of 1,521 patients ( M age = 42.42 years), who had diagnostic labels of major depressive disorder (MDD n = 406), panic disorder (PD n = 198), social anxiety disorder (SAD n = 116), obsessive-compulsive disorder (OCD n = 66), comorbid MDD and any anxiety disorder ( n = 636), or comorbid anxiety disorders ( n = 99). As a result, we identified the following four transdiagnostic clusters characterized by i) strong OCD and PD symptoms, and moderate MDD and SAD symptoms ii) moderate MDD, PD, and SAD symptoms, and weak OCD symptoms iii) weak symptoms of all four disorders and iv) strong symptoms of all four disorders. Simultaneously, a covariance symptom network within each cluster was visualized. The discussion highlighted that the GGMM-based clusters help us generate clinical hypotheses for transdiagnostic clusters by enabling further investigations of each symptom network, such as the calculation of centrality indexes.
