The role of interpersonal trust in the associations between parental warmth and depressive symptoms among Chinese adolescents: A mediation analysis.

The rising rates of adolescent depression have become a critical concern, with family dynamics and interpersonal communication playing a significant role in this mental health issue. However, research on the combined effects of parental warmth and interpersonal trust on adolescent depressive symptoms remains limited. This study aimed to explore the association between parental warmth, interpersonal trust, and depressive symptoms in Chinese adolescents. The sample included 2745 adolescents aged 9 to 18 from the China Family Panel Studies (CFPS). Depressive symptoms were assessed using the CES-D8 scale, which yielded an average score of 4.34. Among participants, 11.3% exhibited symptoms consistent with depression. Multivariate linear regression revealed that both parental warmth (β = -0.296, p < 0.001) and interpersonal trust (β = -0.197, p < 0.001) significantly predicted lower depressive symptoms. Mediation analysis indicated that interpersonal trust partially mediated the relationship between parental warmth and depressive symptoms, explaining 17.68% of the total effect (β = -0.032, 95% CI = -0.060, -0.016). These associations remained significant even after controlling for demographic variables. Our findings suggest that parental warmth protects against depressive symptoms, with interpersonal trust enhancing this protective effect. Interventions focused on fostering parental warmth and enhancing interpersonal trust could improve adolescent mental health.
