Abstract

Suicide occurs at high rates in both military and veteran populations. The Interpersonal Theory of Suicide is a widely applied framework incorporating the requisite construct of acquired capability for suicide, which is the ability to engage in suicidal behaviors developed through painful and provocative life experiences. The Acquired Capability for Suicide Scale (ACSS) was developed to assess this construct. Despite substantial literature examining Interpersonal Theory of Suicide in military samples, many versions of ACSS have been used without adequate validation. The goal of this study was to examine the factor structure of the ACSS and derive a version of the ACSS with initial validity for use in military populations. We also examined the stability of acquired capability over time. Data were collected among Wisconsin Army National Guard service members, who were deployed to the Middle East from 2008 to 2010, at three assessment points: before deployment (n = 714), immediately after return from deployment (n = 2,553), and 6-9 months postdeployment (n = 646). Exploratory and confirmatory factor analyses of postdeployment data suggest adoption of a novel, abbreviated 15-item, four-factor version of the ACSS. Analyses provided preliminary support for discriminant and predictive validity. Results also revealed that acquired capability for suicide increases after deployment and remains stable for at least 6-9 months after return from the combat. The four-factor version of the ACSS shows promise as a theory-relevant and empirically supported instrument for research and clinical applications in the military population.

军人自杀获得性能力量表(ACSS)的因素结构研究:四因素ACSS量表的初步开发与验证。
军人和退伍军人的自杀率都很高。人际自杀理论是一个广泛应用的框架,它包含了获得性自杀能力的必要结构,这是一种通过痛苦和挑衅的生活经历发展起来的从事自杀行为的能力。我们编制了自杀获得能力量表(ACSS)来评估这一概念。尽管大量文献研究了军事样本中的人际自杀理论,但许多版本的ACSS都没有得到充分的验证。本研究的目的是检验ACSS的因素结构,并推导出一个具有初始效度的ACSS版本,用于军事人群。我们还检查了获得能力随时间的稳定性。从2008年到2010年被部署到中东的威斯康辛州陆军国民警卫队服役人员中收集数据,在三个评估点:部署前(n = 714),从部署返回后立即(n = 2553)和部署后6-9个月(n = 646)。部署后数据的探索性和验证性因素分析建议采用一种新颖的,缩短的15项,四因素版本的ACSS。分析提供了初步的判别效度和预测效度支持。结果还显示,获得性自杀能力在部署后增加,并在战斗返回后至少6-9个月内保持稳定。ACSS的四因素版本显示出作为一种理论相关和经验支持的工具在军事人群中的研究和临床应用的前景。(PsycInfo Database Record (c) 2024 APA,版权所有)。
