抑郁应激-认知易感性模型在中国大学生中的构建与验证

目的 在中国大学生人群中对抑郁的应激-认知易感性模型进行初步构建和实证分析.方法 647名大学生完成测验,测查量表为学生日常生活和学习应激量表(GSASHS)和流调中心用抑郁量表(CES-D),认知方式问卷(CSQ)、功能失调态度量表(DAS)、反应方式问卷(RSQ.SF)、自尊问卷(SEQ),1月后进行追踪测查.结果 认知易感因素与应激的交互作用进入回归方程,对抑郁的发作均有预测作用,增强了抑郁发作的可能(P<0.01);路径分析显示:负性认知→过分思虑→抑郁是一条重要的作用路径,过分思虑是一个关键的中介(β=-0.31,P<0.01);整合的应激-认知易感性模型有较好的拟合指数,GFI=0.95,CFI=0.94,IFI=0.94,RMSEA=0.085.结论 在中国大学生人群初步的构建和验证了一个抑郁的应激-认知易感性模型,过分思虑是一个关键的中介.

Abstract：

Objective To test the validity of the stress-cognition vulnerability-model of depression in Chinese undergraduates.Methods 647 undergraduate students finished the Chinese version of 6 scales in time one.Cognitive Style Questionnaire(CSQ),Response Styles Questionnaire(RSQ-SF),Self-Esteem Questionnaire(SEQ),Dysfunctional Attitudes Scale(DAS),General Social and Academic Hassles Scale for Students(GSASHS),Center for Epidemiologic Studies Depression Scale(CES-DA)follow-up assessment in 1 month later,the General Social and Academic Hassles Scale for Students(GSASHS)scale and Center for Epidemiologic Studies Depression Scale (CES-D)scale were completed.Then,vulnerability factors for depression symptoms were used to predict depression symptoms by Multiple Hierarchical Regression(MHR).Path analysis and structural equation model(SEM)were used to explore integrated vulnerability-stress model of depression in Chinese undergraduates.Results Vulnerability-stress interaction was entered into regression equation.The results showed that the vulnerability-stress interaction provided incremental predictive validity to depressive.Symptoms path analysis showed that negative cognition→rumination→depression was a important pathways to cause depression(β=-0.31,P<0.01).The structural equation model for integrated vulnerability-stress model of depression analysis indicated the fit index:GFI =0.95,CFI=0.94,IFI=0.94,RMSEA=0.085.Conclusion A cognition vulnerability-stress medels of depression in Chinese undergraduates was provided and to be confirmed.The rumination was a important mediated variable.
