自杀预防和干预研究需要一种标准的方法来评估自杀意念和行为，以识别高危人群并跟踪治疗反应。哥伦比亚自杀严重程度评定量表(C-SSRS)旨在量化自杀意念和行为的严重程度。作者检验了该量表的心理测量学特性。三个多点研究分析了C-SSRS相对于其他自杀意念和行为测量的有效性及其意念强度子量表的内部一致性：青少年自杀未遂者的治疗研究(N=124)；抑郁症青少年的药物疗效试验(N=312)；以及因精神原因到急诊室就诊的成年人的研究(N=237)。C-SSRS与其他多信息者自杀意念和行为量表具有良好的收敛和发散效度，与另一种行为量表和独立的自杀评定量表相比，对自杀行为分类具有较高的敏感性和特异性。思维和行为两个子量表都对时间的变化很敏感。构思分量表的强度表现出中等到较强的内部一致性。在青少年自杀未遂者的研究中，C-SSRS上最糟糕的终生自杀意念预测了研究期间的自杀企图，而自杀意念量表没有。在研究期间，具有两个最高水平的构思严重程度(意图或计划意图)的参与者在研究期间试图自杀的几率更高。这些发现表明，C-SSRS适合于在临床和研究环境中评估自杀意念和行为。
Research on suicide prevention and interventions requires a standard method for assessing both suicidal ideation and behavior to identify those at risk and to track treatment response. The Columbia–Suicide Severity Rating Scale (C-SSRS) was designed to quantify the severity of suicidal ideation and behavior. The authors examined the psychometric properties of the scale. The C-SSRS’s validity relative to other measures of suicidal ideation and behavior and the internal consistency of its intensity of ideation subscale were analyzed in three multisite studies: a treatment study of adolescent suicide attempters (N=124); a medication efficacy trial with depressed adolescents (N=312); and a study of adults presenting to an emergency department for psychiatric reasons (N=237). The C-SSRS demonstrated good convergent and divergent validity with other multi-informant suicidal ideation and behavior scales and had high sensitivity and specificity for suicidal behavior classifications compared with another behavior scale and an independent suicide evaluation board. Both the ideation and behavior subscales were sensitive to change over time. The intensity of ideation subscale demonstrated moderate to strong internal consistency. In the adolescent suicide attempters study, worst-point lifetime suicidal ideation on the C-SSRS predicted suicide attempts during the study, whereas the Scale for Suicide Ideation did not. Participants with the two highest levels of ideation severity (intent or intent with plan) at baseline had higher odds for attempting suicide during the study. These findings suggest that the C-SSRS is suitable for assessment of suicidal ideation and behavior in clinical and research settings.
