Theoretical perspectives into suicidality have suggested that heightened perceptions of defeat and entrapment lead to suicidality. However, all previous empirical work has been cross-sectional. We provide the first longitudinal test of the theoretical predictions, in a sample of 79 students who reported suicidality. Participants completed self-report measures of suicidal ideation, depression, defeat, and entrapment at two time points, approximately 12 months apart. People higher in defeat became more suicidal over time (β= .45), with baseline levels of suicidality and depressive symptoms controlled. The current results support the posited role of perceived defeat in driving suicidal ideation.
自杀理论观点表明，对挫败和困境的高度感知会导致自杀倾向。然而，之前所有的实证研究都是横断面的。我们在 79 名报告有自杀倾向的学生样本中首次进行了理论预测的纵向测试。参与者在大约 12 个月的两个时间点完成了自杀意念、抑郁、挫败和困境的自我报告测量。与控制基线自杀倾向和抑郁症状相比，挫败感较高的人随着时间的推移变得更加自杀（β=.45）。目前的结果支持了感知到的挫败感在驱动自杀意念中的作用。
