摘要

Adolescent non-suicidal self-injury (NSSI) constitutes a significant public health concern, with perfectionism identified as a key risk factor. However, the mechanisms underlying the association between perfectionism and NSSI, particularly the roles of emotional resilience and interpersonal distress, remain insufficiently understood. This study examines the mediating role of emotional resilience in the relationship between perfectionism and NSSI, as well as the moderating effect of interpersonal distress on this mediation. A stratified random sampling method was used to recruit 1,054 adolescents (530 females; M = 13.14 years, SD = 0.68), who completed the Adolescent Self-Harm Scale, the Chinese version of the Frost Multidimensional Perfectionism Scale, the Adolescent Emotional Resilience Questionnaire, and the Interpersonal Relationship Diagnostic Scale. Data were analyzed using the PROCESS macro to test the hypothesized mediation and moderation effects. Results indicated that perfectionism was negatively associated with emotional resilience, which, in turn, was negatively associated with NSSI, with emotional resilience partially mediating this relationship. Moreover, interpersonal distress moderated the second stage of the mediation, amplifying the negative association between emotional resilience and NSSI. These findings underscore the importance of emotional resilience in the pathway from perfectionism to NSSI and highlight the moderating role of interpersonal distress. Interventions targeting perfectionism and enhancing emotional resilience may help mitigate the risk of self-injury among adolescents.
