This study examined the risk prediction efficiency of the Reasons for Living Inventory Survival and Coping Beliefs Scale, Beck Hopelessness Scale, Beck Depression Inventory, and the Life Experiences Survey with a sample of 51 newly hospitalized parasuicides. The index of suicidal potential chosen for this study was suicide intent as measured by Beck's Suicide Intent Scale. Regression analyses indicated that the Survival and Coping Beliefs Scale emerged as the single most important predictor of suicide intent. Hopelessness and depression made secondary and nonsignificant contributions. Hopelessness was a significant predictor of suicide intent when analyzed apart from Survival and Coping Beliefs, but not among a subsample of 43 repeat parasuicides. Classification analyses showed that neither hopelessness nor survival and coping beliefs were accurate at classifying low- or high-intent parasuicides. Factors contributing to the efficacy of survival and coping beliefs as a risk prediction index are discussed, as is the false-negative dilemma in suicide risk assessment and prediction.
本研究以51名新住院的自杀未遂者为样本，检验了生存理由量表中的生存与应对信念分量表、贝克绝望量表、贝克抑郁量表以及生活经历调查对自杀风险的预测效率。本研究选用的自杀潜在性指标为贝克自杀意图量表所测量的自杀意图。回归分析表明，生存与应对信念分量表是自杀意图最重要的单一预测指标。绝望感和抑郁程度的预测作用次之且不显著。当单独分析时，绝望感是自杀意图的显著预测指标，但在43名反复自杀未遂者的子样本中并非如此。分类分析表明，绝望感以及生存与应对信念在区分低意图或高意图自杀未遂者时均不准确。文中讨论了生存与应对信念作为风险预测指标有效性的影响因素，以及自杀风险评估与预测中的假阴性困境。
