Suicide-specific rumination, a repetitive mental fixation on one’s suicidal thoughts and intentions, may influence the transition from suicidal thoughts to behaviors. Research on suicide-specific rumination has been hindered by the lack of an independent measurement tool. This article presents the development and validation of a self-report measure of suicide-specific rumination across several samples with lifetime suicidal ideation (Sample 1: N = 494 students; Sample 2: N = 219 community members; Sample 3: N = 128 adults at high risk for suicide). The Suicide Rumination Scale (SRS) item pool was reduced from a pool of 41 items to 8 items that are highly discriminant and of varying levels of difficulty. The SRS demonstrated measurement invariance, convergent validity, and nonredundancy with related measures. Importantly, the SRS differentiated suicide attempters from ideators, suggesting its potential clinical relevance. Overall, these findings suggest that the SRS is a valid and incrementally useful measure of suicide-specific rumination.

评估自杀特定反刍的量表的开发和初步验证:自杀反刍量表

自杀特定的反刍,一种对一个人的自杀念头和意图的重复精神固定,可能会影响从自杀念头到行为的转变。由于缺乏独立的测量工具,对自杀特异性反刍的研究受到了阻碍。本文介绍了对具有终生自杀意念的几个样本的自杀特异性反刍自我报告测量的开发和验证(样本 1:N = 494 名学生;样本 2:N = 219 名社区成员;样本 3:N= 128 名有自杀高风险的成年人)。自杀反刍量表 (SRS) 项目池从 41 个项目池减少到 8 个项目,这些项目具有高度区分性和不同难度。SRS 证明了测量不变性、收敛效度和相关测量的非冗余性。重要的是,SRS 将自杀未遂者与思想者区分开来,表明其潜在的临床相关性。总体而言,这些研究结果表明,SRS 是一种有效且越来越有用的自杀特异性反刍测量方法。
