Abstract:
The current study was to examine the relationship among depressive symptoms, post-traumatic stress symptoms, emotion regulatory self-efficacy and suicide risk. A cross-sectional survey was conducted among 3257 graduate students from a medical college of China. Lifetime prevalence of suicidal ideation, plan and attempt were 25.7%, 1.6%, 1.1%, respectively, with one-year suicidal ideation showing at 6.3%. Structural equation modeling was employed to examine the relative contribution of depressive symptoms, post-traumatic stress symptoms and emotion regulatory self-efficacy on suicide risk. Structural equation model had a highly satisfactory fit [χ2=7.782, df=4, p=0.096; MSEA=0.021; CFI=0.992; GFI=0.997]. Post-traumatic stress symptoms had a direct effect and an indirect effect on suicide risk via emotion regulatory self-efficacy. pressive symptoms also had a direct effect and an indirect effect on suicide risk via emotion regulatory self-efficacy. The depressive and post-traumatic stress symptoms increased the risk of suicide risk, but the variable of emotion regulatory self–efficacy would be served as a buffering factor, decreasing the risk of suicide. The interaction term of depressive symptoms and post-traumatic stress symptoms had a direct effect on suicide risk. A significant interactive effect of depressive and post-traumatic stress symptoms on suicide risk was found.
本研究旨在探讨抑郁症状、创伤后应激症状、情绪调节自我效能与自杀风险之间的关系。对某医学院3257名研究生进行了横断面调查。终生自杀意念，计划和尝试的发生率分别为25.7％，1.6％，1.1％，其中一年自杀意念的发生率为6.3％。采用结构方程模型研究抑郁症状、创伤后应激症状和情绪调节自我效能感对自杀风险的相对贡献。结构方程模型拟合度为[χ2=7.782, df=4, p=0.096; MSEA=0.021; CFI=0.992; GFI=0.997]。创伤后应激症状通过情绪调节自我效能对自杀风险有直接影响和间接影响。抑郁症状通过情绪调节自我效能同样对自杀风险有直接影响和间接影响。抑郁和创伤后应激症状增加了自杀风险，但情绪调节自我效能的变量可作为促进因素，降低自杀风险。抑郁症状与创伤后应激症状的交互作用项对自杀风险有直接影响。抑郁和创伤后应激症状对自杀风险有显著的交互影响。
