A follow-up study to test the concurrent validity of a stress-vulnerability model of suicidal ideation and behavior was conducted. A total of 202 college students (139 females, 63 males) completed self-report measures of life stress, loneliness, depression, dysfunctional cognitions, reasons for living, hopelessness, current suicide ideation, and predictions of future suicide probability. The results of a multiple-regression analysis indicated that 30% of the variation in suicide ideation scores could be accounted for by the linear combination of negative life stress, depression, loneliness, and few reasons for living. The linear combination of current suicide ideation, hopelessness, dysfunctional cognitions, and few reasons for living explained 56% of the variance in self-predicted future suicide probability. The results are interpreted as being supportive of the proposed model.
开展了一项后续研究，以检验自杀意念和行为的压力易感性模型的同时效度。共有202名大学生（139名女性，63名男性）完成了关于生活压力、孤独感、抑郁、功能失调认知、生存理由、绝望感、当前自杀意念以及未来自杀可能性预测的自我报告测量。多元回归分析结果表明，自杀意念得分中30%的变异可由负面生活压力、抑郁、孤独感和生存理由少的线性组合来解释。当前自杀意念、绝望感、功能失调认知和生存理由少的线性组合解释了自我预测未来自杀可能性中56%的方差。结果被解释为支持所提出的模型。
