To examine the psychometric properties of the Columbia- Suicide Severity Rating Scale (C-SSRS) among a cohort of veterans identified to be at risk for suicide.
Convergent, divergent, and predictive validity of the C-SSRS were examined using secondary data from a study of veterans who presented to the psychiatric emergency room (n = 237). Data were collected 1 week, 1 month, 3 months, and 6 months following emergency room discharge.
Results demonstrated good evidence for convergent and divergent validity. Baseline intensity subscale scores predicted actual and interrupted attempts, and any behavior for all available data and for the subsample who had 6-month follow-up data, and also predicted preparatory behavior in the full sample. Baseline severity subscale scores predicted preparatory behavior and any behavior for the full sample and for those with 6 months of follow-up, and actual attempts for the full sample. Severity of ideation cutoff scores was significantly associated with actual attempts and any behavior in both samples. Adding a prior behavior criterion demonstrated similar results.
Findings suggest that the C-SSRS is a psychometrically sound measure that can be used to augment suicide risk assessment with veterans who are already identified to be at risk for suicide.
在一组被确定有自杀风险的退伍军人中，检验哥伦比亚-自杀严重程度评定量表（C-SSRS）的心理测量特性。
利用精神科急诊室就诊退伍军人研究中的二次数据（n=237），对 C-SSRS 的聚合、发散和预测效度进行了检验。数据在急诊室出院后 1 周、1 个月、3 个月和 6 个月时收集。
结果表明，聚合和发散效度具有良好的证据。基线强度子量表评分预测了实际和中断的自杀企图，以及所有可用数据和具有 6 个月随访数据的亚组中的任何行为，也预测了全样本中的预备行为。基线严重程度子量表评分预测了全样本和具有 6 个月随访数据的亚组中的预备行为和任何行为，以及全样本中的实际企图。意念严重程度的截断分数与两个样本中的实际企图和任何行为均显著相关。增加先前行为标准也得出了类似的结果。
研究结果表明，C-SSRS 是一种具有心理测量学意义的可靠测量工具，可以与已经确定有自杀风险的退伍军人一起用于增强自杀风险评估。
