为探讨青少年同伴依恋与抑郁的关系,以及社会支持和自尊在二者关系中的作用机制,采用父母和同伴依恋问卷（IPPA）中的同伴依恋分量表、领悟社会支持量表（PSSS）、自尊量表（SES）和流调中心用抑郁量表（CES-D）对668名中学生进行调查,结果发现：（1）青少年同伴依恋、朋友社会支持和自尊两两之间呈显著正相关,且三者与抑郁均呈显著负相关。（2）青少年同伴依恋不仅能直接负向预测抑郁,而且还能通过自尊的单独中介作用对抑郁产生影响;朋友社会支持的单独中介作用以及社会支持→自尊的链式中介作用在初、高中生群体中存在差异,即在初中生群体中,同伴依恋能够通过社会支持的单独中介作用以及社会支持→自尊的链式中介作用对抑郁产生影响,而在高中生群体中,这两种间接作用均不显著。研究结果揭示了青少年同伴依恋对抑郁产生影响的心理机制,为引导青少年建立良好的同伴依恋,促进自尊及心理健康发展提供了有益建议。

Adolescence was an important period during which adolescents developed many psychical and psychological characteristics so as to be prepared for being adults.

Moreover, developmental psychologists pointed out that adolescents were increasingly rebellious toward parents with the development of self-awareness and their peer intercommunication would increase gradually. These made peer attachment become an important source of social support, security and belonging, which were all important protective factors for adolescents to avoid depression. In addition, the previous research showed that social support and self-esteem had important effects on depression and both social support and self- esteem were negatively correlated with depression. In order to explore the relationship between peer attachment, social support, self-esteem and depression as well as the mechanism the effect of peer attachment on adolescents＇ depression, this study focused on the mediating role of social support and self-esteem between peer attachment and adolescents＇ depression and its learning stage difference. A survey research method was adopted in which the Inventory of Peer Attachment, the Perceived Social Support Scale, the Self-Esteem Scale as well as the Center for Epid
