生活应激诱发大学生抑郁症状及轻生意念预警模型

PREDICTED MODEL OF UNDERGRADUATES′LIFE STRESS INDUCING DEPRESSION AND SUICIDE IDEA

用“大学生人格问卷”(UPI)和“学生生活应激量表”(SLSI)检测大学生3558例,并用回归分析和路经分析探讨其应激过程(应激源—应激反应)诱发抑郁症状及轻生意念的预警模型。结果显示,大学生生活中所承受的挫折、压力、变化和自我强加是预警抑郁症状产生的主要应激源;情绪反应、生理反应、行为反应和认知反应是预警抑郁症状产生的主要应激反应;大学生抑郁症状诱发轻生意念的预测正确率为97.0%,发生比(OR)或危险率1.86倍于非抑郁症状者,其中女生抑郁症状诱发轻生意念的危险率近2倍于无此症状者;应激源直接引起应激反应,应激反应直接诱发抑郁症状,抑郁症状直接引发轻生意念,应激源和应激反应不直接影响轻生意念,而通过诱发抑郁症状间接影响轻生意念。此预警模型为大学生危机心理鉴别干预提供了临床心理学依据和参数。

3558 undergraduates were tested by （SLSI） . The sample was fit for predicted pression and suicide idea with regression and change and self-fore from undergrad University Personality Invention （UPI） and Student-Life Stress Inventory model for undergraduates＇ life stressor and stress reaction inducing deanalysis and path analysis. The results showed： frustration and pressure uates＇ life were important stressor indirect to effect depression, their emotion react and physiological react and behavior react were important stress reaction direct to effect depression. Predicted percentage correct of undergraduates＇ depression inducing suicide idea was 97.0%; OR （odd rat/o） of undergraduates＇ depression inducing suicide idea was 1.86 than not depression; OR of female undergraduates＇ depression inducing suicide idea was 2.00 than not depression. Direct effect of undergrad for their stress reaction and of their stress reaction was 0.53 for their depression and uates＇ stressor was 0.83 of their depression was 0.31 for their suicide idea. Indirect effect of undergraduates＇ stressor was 0.14 and of stressreaction was 0.17 for inducing their suicide idea through their depression but its direct effects were 0.00 and 0.09. The predicted model offers parameter of clinical psychology to intervene undergraduates＇ mental crisis.
