目的：这项研究报告了一个简短的自我管理的筛查问卷哥伦比亚SuicideScreen(R)(CSS)的心理测量学特性，旨在识别有自杀风险的高中生。方法：从1991年到1994年，1,729名9-12年级学生在课余时间完成了社会支持评定量表和贝克抑郁量表。对356名筛查阳性的学生和285名年龄、性别和种族匹配的阴性筛查的学生进行了儿童诊断面试表(DISC)第2.3版的检查，以评估其有效性。基于光盘的自杀风险标准是自杀意念或既往自杀未遂，以及DSM-III-R诊断为严重抑郁症或恶劣心境或药物使用。在85个子样本中评估了重测可靠性。结果：最平衡算法的灵敏度为0.75，特异度为0.83，阳性预测值为16%。自杀意念和先前企图项目的信度(Kappa)分别为0.48和0.58。最平衡计分算法的8天重测信度为0.32。结论：该量表对有自杀倾向的学生具有较好的敏感性和较好的特异性。需要进行第二阶段的评估，以减轻低特异性的负担。
Objective: This study reports on the psychometric properties of a brief, self-administered screening questionnaire, the Columbia SuicideScreen(R) (CSS), intended to identify high school students at risk for suicide. Method: Seventeen hundred twenty-nine 9th- to 12th-grade students completed the CSS and Beck Depression Inventory during school hours in 1991 to 1994. Three hundred fifty-six students who screened positively and 285, group matched on age, gender, and ethnicity, who screened negatively were examined on the Diagnostic Interview Schedule for Children (DISC), version 2.3, to assess validity. The DISC-based suicide risk criterion was suicidal ideation or prior suicide attempt and a DSM-III-R diagnosis of major depression or dysthymia or substance use. Test-retest reliability was assessed in a subsample of 85. Results: The most balanced algorithm had a sensitivity of 0.75, specificity 0.83, and positive predictive value 16%. Suicidal ideation and prior attempt item reliabilities (kappa) were 0.48 and 0.58, respectively. Eight-day test-retest reliability for the most balanced scoring algorithm was 0.32. Conclusions: The CSS demonstrated good sensitivity and reasonable specificity identifying students at risk for suicide. A second-stage evaluation would be needed to reduce the burden of low specificity.
