The Suicide Cognitions Scale (SCS) assesses suicide-specific cognitions which may drive suicide risk. Nonetheless, prior work has been mixed regarding optimal factor structure. Additionally, this measure has not been validated for use with veterans with military sexual trauma-related posttraumatic stress disorder (MST-related PTSD), a population that is at elevated risk for suicidal self-directed violence (SDV). This study sought to determine the optimal factor structure of the SCS for use with veterans with MST-related PTSD as well as its psychometric properties. An exploratory factor analysis revealed a four-factor structure, including unlovability, unbearability, unsolvability, and negative urgency. The SCS also demonstrated excellent internal consistency and good convergent validity. This study identified a novel factor, negative urgency, which may explain some of the predictive power of the SCS found in previous research. This paper provides initial support for a four-factor structure of the SCS among those with MST-related PTSD. Additional work remains necessary in evaluating the SCS as a tool for detecting risk for future suicidal SDV among veterans with MST-related PTSD.

退伍军人性创伤相关创伤后应激障碍自杀认知量表的因素分析

自杀认知量表 (SCS) 评估可能导致自杀风险的自杀特定认知。尽管如此，关于最佳因子结构的先前工作是混合的。此外，该措施尚未经过验证可用于患有军事性创伤相关的创伤后应激障碍（MST 相关的 PTSD）的退伍军人，这是一个面临自杀性自我导向暴力 (SDV) 高风险的人群。本研究旨在确定 SCS 的最佳因子结构，以用于患有 MST 相关 PTSD 的退伍军人及其心理测量特性。探索性因素分析揭示了一个四因素结构，包括不可爱、无法忍受、无法解决和消极紧迫感。SCS 还表现出出色的内部一致性和良好的收敛效度。这项研究确定了一个新因素，消极紧迫感，这可以解释之前研究中发现的 SCS 的一些预测能力。本文为 MST 相关 PTSD 的 SCS 的四因素结构提供了初步支持。在评估 SCS 作为检测患有 MST 相关 PTSD 的退伍军人未来自杀性 SDV 风险的工具方面，仍有必要开展其他工作。
