Background and Aim: The Suicide Cognitions Scale (SCS) was developed to assess a broad range of suicide-related cognitions. Research to date supports the scale's factor structure, internal consistency, and construct validity. The present study tested the scale's prospective validity for suicide attempts among 97 military personnel presenting to an emergency department or psychiatric outpatient clinic for an unscheduled walk-in evaluation. Method: Cox regression and receiver operator characteristic analyses were conducted to test the prospective validity of the SCS. Results: Results supported the prospective validity of the SCS (area under the curve [AUC] = 0.69) and indicate the scale's performance is comparable to an empirically supported measure of suicide ideation (AUC = 0.75). The SCS performance was not reduced by removing items containing the word suicide. Limitations: Homogeneous sample comprised of US soldiers, predominantly male, with recent suicidal ideation. Conclusion: Results support the SCS as an indicator of subsequent risk for suicidal behavior when used in acute care settings, and suggest the scale's performance is similar to more traditional suicide risk screening methods that depend on honest self-disclosure of suicidal thoughts.

自杀认知量表在寻求计划外精神干预的急性自杀军人中的前瞻性有效性

背景和目的：开发自杀认知量表 (SCS) 来评估范围广泛的与自杀相关的认知。迄今为止的研究支持量表的因素结构、内部一致性和结构效度。本研究测试了该量表在 97 名到急诊室或精神科门诊进行计划外预约评估的军人中自杀企图的前瞻性有效性。方法：通过 Cox 回归和接受者操作特征分析来测试 SCS 的前瞻性有效性。结果：结果支持 SCS 的前瞻性有效性（曲线下面积 [AUC] = 0.69），并表明该量表的表现与经验支持的自杀意念衡量指标（AUC = 0.75）相当。删除包含自杀一词的项目并没有降低 SCS 的性能。局限性：均质样本由美国士兵组成，主要是男性，最近有自杀意念。结论：结果支持 SCS 作为在急性护理环境中使用时发生自杀行为的后续风险的指标，并表明该量表的性能类似于更传统的自杀风险筛查方法，这些方法依赖于自杀想法的诚实自我披露。
