Abstract
Objective: Although empirical evidence of NSSI contagion within adolescent friendships has been documented, the specific mechanisms remain poorly understood. The current study employed a longitudinal design to investigate the influence of NSSI in adolescents' peer groups on their own NSSI behaviors. Additionally, the study examined the mediating role of self-esteem and the specific conditions under which NSSI contagion occurs.
Method: The study involved 326 adolescents (mean age = 13.5, 59.2% female) nested within 163 friendship dyads. NSSI behavior, self-esteem, self-compassion, alexithymia, and personal distress were assessed at baseline (T1), and NSSI behavior was assessed again after three months (T2). A cross-lagged Actor-Partner Interdependence Model (APIM) was used to estimate the NSSI contagion model. In this model, self-esteem served as a mediator in the contagion of NSSI behaviors, while alexithymia, self-compassion, and personal distress acted as moderating factors of this mediating effect.
Results: This study revealed that friends' NSSI status at baseline significantly predicted adolescents' own NSSI status after three months. Self-esteem was found to mediate the NSSI contagion effect exclusively in situations where adolescents exhibited high alexithymia, low self-compassion, and high personal distress.
Conclusions: This research highlights the role of adolescent friendships in NSSI contagion and elucidates the potential mediating role of self-esteem in this contagion. These findings may provide substantial implications for the prevention of the NSSI contagion among adolescents.
期刊介绍：
Child and Adolescent Psychiatry and Mental Health, the official journal of the International Association for Child and Adolescent Psychiatry and Allied Professions, is an open access, online journal that provides an international platform for rapid and comprehensive scientific communication on child and adolescent mental health across different cultural backgrounds. CAPMH serves as a scientifically rigorous and broadly open forum for both interdisciplinary and cross-cultural exchange of research information, involving psychiatrists, paediatricians, psychologists, neuroscientists, and allied disciplines. The journal focusses on improving the knowledge base for the diagnosis, prognosis and treatment of mental health conditions in children and adolescents, and aims to integrate basic science, clinical research and the practical implementation of research findings. In addition, aspects which are still underrepresented in the traditional journals such as neurobiology and neuropsychology of psychiatric disorders in childhood and adolescence are considered.
