Abstract: Non-suicidal self-injury (NSSI) is a serious public health concern in adolescents. In 2013, DSM-5 recognized NSSI as a distinct clinical phenomenon and made a call for more systematic research by including Non-Suicidal Self-Injury-Disorder (NSSI-D) as a condition requiring further research. Yet, few studies have examined the prevalence of NSSI-D in adolescents using the exact DSM-5 criteria. Additionally, the few studies available criticised several of the proposed diagnostic criteria and pointed out that more research is needed. Therefore, we examined prevalence rates of NSSI-D and investigated the four most controversial criteria (i.e., criteria A, B/C, and E) in a large community s le of adolescents (N = 2,130 54% female M Our results show an overall NSSI-D prevalence rate of 7.6%, with significantly more girls (11.7%) than boys (2.9%) meeting the diagnosis. The prevalence of NSSI-D dropped to 5.5% when an alternative criterion A (i.e., ≥10 days of NSSI in the past year) was implemented. In our s le, 87% and 99% of adolescents with lifetime NSSI met criteria B and C, which clearly questions the clinical utility of these criteria for the DSM-5 diagnosis of NSSI-D. Importantly, however, although criterion E received relatively low endorsement, it significantly distinguished adolescents with and without NSSI-D from one another. Although our conclusions are restricted by the cross-sectional nature of our study, these findings show that NSSI-D is common in community adolescents and offer new insights in the endorsement and clinical utility of specific NSSI-D criteria.

Abstract: Non-suicidal self-injury (NSSI) constitutes a significant mental health concern that is highly prevalent in adolescence. Theoretical accounts and empirical research suggest that, in the short-term, NSSI may provide instant relief from intense psychological distress and ruminative thoughts. However, much less is known about these associations over time throughout adolescence. Therefore, we designed a three-year longitudinal study and examined the bidirectional prospective associations between psychological distress, rumination, and NSSI. We assessed 528 secondary school students (at Time 1: Mean age = 15.0 years, SD = 1.85, range 11 to 19 years, 50.6% female, 98.7% of Belgian nationality) using self-report questionnaires at three annual measurement points. Cross-lagged structural equation modelling was performed to examine the directionality of associations. Results indicated positive bidirectional associations between (1) distress and NSSI and positive unidirectional associations between (2) distress and rumination, and (3) NSSI and rumination. The current study embeds NSSI in a broader network of cognitive and emotional antecedents and consequents, and is the first to consider the long-term influence these components exert on each other. As NSSI may play a significant part in increasing distress and rumination, the behaviour potentially sustains a longer-term maladaptive cycle between emotion, cognition, and NSSI. Clinical implications of these findings are discussed.

Abstract: Abstract. Identity difficulties have been associated with various psychiatric conditions and are considered a central issue in personality pathology. Following the Alternative Model for Personality Disorders, measures of self- and interpersonal functioning have been developed. Although these measures were intended to be separate ratings of self-other deficits, only a global rating was obtained. Moreover, these measures fall short in bridging the gap between developmental and clinical identity work. To capture both adaptive and disturbed identity dimensions, Kaufman et al. (2015) developed the Self-Concept and Identity Measure (SCIM) that assesses consolidated identity, disturbed identity, and lack of identity. Using two-wave longitudinal data (2,150 adolescents 54.2% girls age range = 12–19), this study investigated the factor structure and reliability of the Dutch SCIM, its measurement invariance across time, its longitudinal measurement invariance across gender and age groups, and associations of the SCIM with identity synthesis and confusion, Big-Five personality traits, and borderline personality disorder features. Consolidated identity scores were positively related to identity synthesis and adaptive Big-Five traits, whereas negatively related to identity confusion, neuroticism, and borderline features. Opposite associations were obtained for disturbed identity and lack of identity scores. The Dutch SCIM appeared to produce valid and reliable scores and seemed suited to assess longitudinal identity functioning in Belgian adolescents.
