青少年自尊与抑郁的关系:迷思的中介作用

A Study on the Relationship Between Self-esteem and Depression:Mediator Role of Rumination

目的:了解青少年外显自尊、内隐自尊、迷思与抑郁的关系。方法:采用Rosenberg自尊问卷、流调中心用抑郁量表(CES-D)、迷思反应问卷和自尊IAT测量171名青少年。结果:外显自尊与迷思呈显著负相关(r=-0.394,P<0.001),与抑郁呈显著负相关(r=-0.467,P<0.001),迷思与抑郁呈显著正相关(r=0.634,P<0.001)。迷思在外显自尊与抑郁之间发挥着部分中介作用,当迷思进入回归方程时,外显自尊对抑郁的预测效应从0.467降低为0.258;中介性调节分析发现,当迷思进入回归方程时,外显自尊×内隐自尊对抑郁的预测效应从-0.169降为-0.090(β=-0.090,t=-1.499,P=0.139)。结论:外显自尊×内隐自尊对抑郁的预测效应是通过迷思这一中介变量实现的。

Objective： To investigate the relationship of explicit self-esteem, implicit self-esteem, rumination and depression in a sample of adolescents. Methods： 171 adolescents were investigated by Rosenherg Self-esteem Scale, CES-D, Ruminative Responses Scale and self-esteem IAT. Results： Pearson＇s correlation analysis showed a significant and negative relationship between explicit self-esteem and rumination （r=-0.394, P〈0.001） and depression （r=-0.467, P〈 0.001）. However, rumination and depression correlated positively （r=0.634, P〈0.001）. It showed that rumination partially mediated the effect of explicit self-esteem on depression. Once rumination entered the regression equation as a predictor, the index of the effect of explicit self-esteem×implicit self-esteem on depression dropped from-0.169 to -0.090 （β=- 0.090, t=-1.499, P=0.139, n.s.）. Conclusion： The effect of explicit self-esteem × implicit self-esteem on depression was mediated by rumination.
