The Relationship between Psychological Needs Frustration and Depression among Chinese Adolescents: The Mediating Role of Self-Esteem and the Moderating Role of Psychological Suzhi

Previous studies have demonstrated that psychological needs frustration strongly influences adolescent depression. However, this influence's underlying mechanisms remain unknown, and related protective factors have not been identified. Based on an integration of basic psychological needs theory, the cognitive vulnerability model of depression, and findings regarding the link between psychological suzhi (a Chinese cultural construct that includes a hierarchical and integrated set of positive psychological qualities) and mental health, we assessed a structural equation model examining the mediating role of self-esteem and moderating role of psychological suzhi in the relationship between psychological needs frustration and depression. Participants were 1552 Chinese adolescents (Mage = 12.30, SD = 0.54, 49.10% male) who effectively completed paper-based questionnaires. The results indicated that psychological needs frustration significantly and positively predicted adolescent depression. Furthermore, the relationship between psychological needs frustration and depression was significantly mediated by self-esteem and significantly moderated by psychological suzhi; specifically, psychological suzhi buffered the association between psychological needs frustration and adolescents' depression. Additionally, we provide further evidence for the relationship between psychological needs frustration and depression, revealing the relevant underlying mechanisms and protective factors; these findings have practical relevance in the prevention and treatment of Chinese adolescents' depression.
