AI Insight
This study of 939 Chinese early adolescents found gender-specific pathways linking best friends' depressive symptoms to adolescents' own depression. Among girls, having a best friend with depressive symptoms was indirectly associated with their own depressive symptoms through lower friendship quality and increased rumination. Among boys, the direct link between best friends' and their own depressive symptoms was stronger when the best friend had higher peer acceptance, but the indirect pathways through friendship quality and rumination were not significant.
Why it matters
These findings suggest that interventions for adolescent depression may need to be gender-specific and consider the broader peer context. Understanding how best friends' mental health influences adolescents differently based on gender and social status could inform more targeted prevention and treatment approaches in school settings.
Understand the Science
IntroductionAlthough best friends’ depressive symptoms have been linked to adolescents’ own depressive symptoms, inconsistent findings point to the need to examine potential pathways and the peer-status contexts in which these links unfold.MethodsUsing cross-sectional data from 939 Chinese early adolescents (Mage = 13.31 years; 49.2% girls), this study tested whether best friends’ depressive symptoms were associated with adolescents’ depressive symptoms through friendship quality and rumination, and whether these associations varied according to peer acceptance of best friends and adolescents themselves. Depressive symptoms, friendship quality, and rumination were assessed using self-reports, whereas peer acceptance and best-friend identification were obtained through peer nominations.ResultsAmong girls, best friends’ depressive symptoms were indirectly associated with adolescents’ depressive symptoms through poorer friendship quality and greater rumination. Among boys, these indirect pathways were not significant; however, the association between best friends’ depressive symptoms and boys’ own symptoms was stronger when best friends’ peer acceptance was higher. Among girls, higher peer acceptance was related to a weaker association between rumination and depressive symptoms and a smaller indirect association through rumination.DiscussionThese findings highlight potentially different patterns across gender-stratified analyses and the peer-status contexts of both adolescents and their best friends in understanding adolescent depressive symptoms.
