Objective Research on suicide contagion has suggested that exposure to suicide-related thoughts and behaviors of others promotes one's personal risk for suicide. However, our understanding of the role suicidal exposure plays in the development of suicide risk is underdeveloped. This limited understanding may be due, in part, to the lack of a validated measure of exposure to suicidal behavior. The present study aimed to develop and validate a comprehensive self-report instrument of exposure to suicidal behaviors. Method Using two independent convenience samples of undergraduate students, exploratory structural equation modeling (ESEM) was performed on a newly developed measure of suicidal exposure. Results Data supported a three-factor model of suicidal exposure: exposure to suicidal communication, direct exposure to suicide deaths and attempts, and indirect exposure to suicide deaths and attempts. Each factor demonstrated positive bivariate associations with depressive symptoms, posttraumatic stress disorder symptoms, suicide ideation, and suicide attempt history, suggesting convergent validity. Analyses demonstrated generally acceptable internal consistency. Conclusion This instrument will facilitate the study of suicidal exposure. Further validation of this scale, with attention to its reliability and invariance across gender and other demographic variables in clinically relevant samples, will be important for advancing the assessment of suicidal exposure and understanding its relation to suicide risk.

自杀行为暴露量表的初步验证。

客观 对自杀传染的研究表明，接触他人与自杀相关的想法和行为会增加个人的自杀风险。然而，我们对自杀暴露在自杀风险发展中所起的作用的理解尚不成熟。这种有限的理解可能部分是由于缺乏对暴露于自杀行为的有效测量。本研究旨在开发和验证一种全面的自杀行为暴露自我报告工具。方法 使用两个独立的本科生便利样本，对新开发的自杀暴露量度进行探索性结构方程模型 (ESEM)。结果 数据支持自杀接触的三因素模型：接触自杀交流、直接接触自杀死亡和未遂、以及间接暴露于自杀死亡和企图。每个因素都与抑郁症状、创伤后应激障碍症状、自杀意念和自杀未遂史呈正相关，表明收敛效度。分析表明普遍可接受的内部一致性。结论 该仪器将有助于自杀暴露的研究。进一步验证该量表，注意其在临床相关样本中跨性别和其他人口统计变量的可靠性和不变性，对于推进自杀暴露的评估和了解其与自杀风险的关系非常重要。自杀意念和自杀未遂史，表明收敛效度。分析表明普遍可接受的内部一致性。结论 该仪器将有助于自杀暴露的研究。进一步验证该量表，注意其在临床相关样本中跨性别和其他人口统计变量的可靠性和不变性，对于推进自杀暴露的评估和了解其与自杀风险的关系非常重要。自杀意念和自杀未遂史，表明收敛效度。分析表明普遍可接受的内部一致性。结论 该仪器将有助于自杀暴露的研究。进一步验证该量表，注意其在临床相关样本中跨性别和其他人口统计变量的可靠性和不变性，对于推进自杀暴露的评估和了解其与自杀风险的关系非常重要。
