通过整群抽样的方法抽取了1404名中学生，对其施测核心自我评价量表，我的班级问卷和抑郁问卷，应用无约束结构方程模型技术和结构方程中介效应检验技术，分别考察了核心自我评价在班级环境与抑郁关系间的调节与中介作用。结果表明：（1）核心自我评价对班级环境中的师生关系、同学关系、竞争三者和抑郁之间的关系起着调节作用，但结构模型的拟合指数不佳；（2）核心自我评价在班级环境与青少年抑郁间起着中介作用，其中核心自我评价在竞争与抑郁间关系起着完全中介作用。

To analyze the relationships between class environment, core self-evaluation and adolescent depression, 1404 high school students were chosen at random to complete the CSES, Class Environment Scale and CES-D. Unconstrained model method and Structural Equation Modeling were used to examine the moderation and mediation effect of core self-evaluation between class environment and adolescent depression. The results show that: (a) core self-evaluation exerts the moderating effects in the relation between teacher-student relationships, students relations, competition and adolescent depression, but it shows poor fit indices of structural models; (b) core self-evaluation exerts the mediating effect in the relation between classroom environment and adolescent depression, of which the core self-evaluation exerts a complete medium effect in the relation between competition and depression.
