Suicidal ideation (SI) is common, harmful, and distressing. Prior research suggests a person's sense of perceived control over their suicidal thoughts may be important for understanding risk level. However, no measurement tool currently exists to capture this experience. The present study seeks to establish a brief self-report instrument to assess the degree of perceived control an individual has over their suicidal thoughts. We conducted two studies to test the psychometric properties and factor structure of the Controllability of Suicidal Thoughts (CoST) scale. Two online convenience samples were used; participants were recruited via Prolific (Study 1; n = 244, Mage = 29.19, female = 51.2%, White = 68.9%, non-Hispanic = 92.6%, heterosexual = 48.0%) and via online webpages and forums (Study 2; n = 206, Mdnage = 25-30 years, female = 56.5%, White = 55.2%, non-Hispanic = 84.4%, heterosexual = 51.3%). Exploratory factor analyses (Study 1) yielded a two-factor structure for the CoST, which was replicated in the second sample. CoST scores were associated with various constructs related to suicidality (i.e., SI severity, self-efficacy to avoid suicidal action, suicide-related coping, hopelessness), locus of control, coping, and emotion dysregulation. Results indicate the CoST has high internal consistency (ω = .92), good test-retest reliability, and preliminary evidence of predictive and construct validities. The CoST shows promise for future research applications, aids our understanding of suicide-related cognitions, and may predict important suicide-related outcomes.

自杀念头的可控性 (CoST) 量表：开发、因素结构和初步验证。

自杀意念 (SI) 很常见、有害且令人痛苦。先前的研究表明，一个人对自杀想法的控制感可能对于了解风险水平很重要。然而，目前还没有测量工具来捕捉这种体验。本研究旨在建立一个简短的自我报告工具来评估个人对其自杀想法的控制程度。我们进行了两项研究来测试自杀想法可控性（CoST）量表的心理测量特性和因素结构。使用了两个在线便利样本；参与者是通过 Prolific（研究 1；n = 244，法师 = 29.19，女性 = 51.2%，白人 = 68.9%，非西班牙裔 = 92.6%，异性恋 = 48.0%）以及在线网页和论坛（研究 2；n = 206，Mdnage = 25-30 岁，女性 = 56.5%，白人 = 55.2%，非西班牙裔 = 84.4%，异性恋 = 51.3%）。探索性因素分析（研究 1）得出了 CoST 的双因素结构，该结构在第二个样本中得到了复制。CoST评分与自杀相关的各种结构（即SI严重程度、避免自杀行为的自我效能、与自杀相关的应对、绝望）、控制源、应对和情绪失调相关。结果表明 CoST 具有较高的内部一致性 (ω = .92)、良好的重测可靠性以及预测和构建有效性的初步证据。CoST 为未来的研究应用带来了希望，有助于我们理解与自杀相关的认知，并可以预测重要的与自杀相关的结果。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
