In order to advance the detection and prevention of suicide, recent research has focused on predictors of suicidal ideation and behavior such as negative cognitive styles, dysfunctional attitudes, hopelessness, and rumination. In this study the relationships among these risk factors in the context of the Attention Mediated Hopelessness (AMH) theory of depression are examined. One hundred and twenty-seven undergraduates in the Cognitive Vulnerability to Depression (CVD) project were followed for 2.5 years. The CVD project followed initially nondepressed freshmen, at either high or low cognitive risk for depression, in order to predict onsets and recurrences of depressive disorders. The presence and duration of suicidal ideation were predicted prospectively by rumination and hopelessness, and hopelessness partially mediated the relationship between rumination and ideation and fully mediated the association between rumination and duration of suicidality. Further, rumination mediated the relationship between cognitive vulnerability and suicidal ideation.
为了推进自杀的检测与预防工作，近期的研究聚焦于自杀意念和行为的预测因素，如消极认知风格、功能失调性态度、绝望感和反复思考。在本研究中，我们考察了抑郁的注意力介导绝望感（AMH）理论背景下这些风险因素之间的关系。对抑郁认知易感性（CVD）项目中的127名本科生进行了为期2.5年的跟踪研究。CVD项目跟踪了最初没有抑郁症状、抑郁认知风险高或低的大一新生，以预测抑郁症的发作和复发情况。反复思考和绝望感可前瞻性地预测自杀意念的出现和持续时间，绝望感部分介导了反复思考与意念之间的关系，并完全介导了反复思考与自杀意念持续时间之间的关联。此外，反复思考介导了认知易感性与自杀意念之间的关系。
