A preliminary model of the escape theory of suicide was tested in 168 college students (52 males, 116 females), who completed self-report measures of self-oriented, other-oriented, and socially prescribed perfectionism, negative life stress, depression, hopelessness, anxiety, reasons for living, and suicidal behaviors. A path analysis provided only partial validation for the model and accounted for 26% of the variance in suicidal behaviors. None of the three dimensions of perfectionism significantly accounted for any additional variance in suicidal behaviors above and beyond the other variables used in the study. Socially prescribed perfectionism was the only dimension of perfectionism that showed a statistically significant bivariate correlation with suicidal behaviors. The path analysis indicated that this correlation was an indirect effect through reasons for living. Depression was a better predictor of suicidal behaviors than hopelessness. Perhaps one reason for these equivocal results was the limited amount of variability in suicidal behaviors in this nonclinical sample.
在168名大学生（52名男性，116名女性）中对自杀逃避理论的初步模型进行了测试，这些学生完成了关于自我导向、他人导向和社会规定的完美主义、负面生活压力、抑郁、绝望、焦虑、生存理由以及自杀行为的自我报告测量。路径分析仅为该模型提供了部分验证，解释了自杀行为中26%的方差。完美主义的三个维度中，没有一个能在该研究使用的其他变量之外，显著解释自杀行为中的任何额外方差。社会规定的完美主义是完美主义的唯一维度，与自杀行为呈现出具有统计学意义的双变量相关性。路径分析表明，这种相关性是通过生存理由产生的间接效应。抑郁比绝望更能预测自杀行为。这些模棱两可结果的一个可能原因是，这个非临床样本中自杀行为的变异性有限。
