A measure of suicide risk was developed using items reported to discriminate suicidal patients from controls in various studies. The new self-report scale was administered to 82 outpatients, 157 inpatients, and 83 college students. Using total scores, significant differences were found between the college sample and the two patient samples. The scale also discriminated between patients who reported one or more past suicide attempts and those who reported none. An independent cross-validation showed that half of the items continued to discriminate between patient and control groups. Sensitivity and specificity estimates were also determined. The test does not attempt to predict a specific rare event, i.e., suicide. It attempts to describe the degree to which a given individual reveals a set of characteristics that are similar to a suicide prototype.
利用在各项研究中据报告可区分自杀患者与对照者的项目制定了一种自杀风险测量方法。新的自我报告量表施用于82名门诊患者、157名住院患者和83名大学生。使用总分，发现大学生样本与两个患者样本之间存在显著差异。该量表还能区分报告有一次或多次既往自杀未遂的患者和未报告有自杀未遂的患者。一项独立的交叉验证表明，一半的项目继续区分患者组和对照组。还确定了敏感性和特异性估计值。该测试并非试图预测特定的罕见事件，即自杀。它试图描述特定个体展现出与自杀原型相似的一组特征的程度。
