Abstract

Recent national estimates suggest that 1 in 2 women will experience intimate partner violence (IPV) in their lifetime. Given the high prevalence of posttraumatic stress disorder (PTSD) among women experiencing IPV, it is necessary to consider whether PTSD assessments function adequately for this population. Thus, the present study aimed to evaluate the psychometric properties of the past-month version of the PTSD Checklist for DSM-5 (PCL-5), one of the most widely used self-report measures of PTSD symptoms, in a sample of community women experiencing IPV. Participants were 158 women who had experienced IPV in the past 6 months (Mage = 40.14 years, 39.9% White). The PCL-5 demonstrated good internal consistency, Cronbach's α = .97, and scores were significantly positively correlated with theoretically related constructs (i.e., PTSD symptom count on the SCID-5, IPV severity, substance use, depression, anxiety, and emotion dysregulation); however, it demonstrated poor 30-day stability, r = .38, ICC = .55. The ability of the PCL-5 to discriminate with respect to a PTSD diagnosis was acceptable, AUC = .74. A cutoff score of 21 maximized sensitivity (82.5%) and specificity (55.4%); this is lower than typical cutoffs (i.e., 31–33). Although the PCL-5 has generally demonstrated adequate psychometric properties, findings suggest that it does not function optimally for women experiencing IPV relative to its functioning for other trauma-exposed populations. The lower-than-typical cutoff suggests that the PCL-5 may underestimate PTSD prevalence among women experiencing IPV.

在遭受亲密伴侣暴力的妇女中对 DSM-5 创伤后应激障碍清单进行心理计量学评估。
最近的全国性估计表明,每两名女性中就有一名在其一生中会遭遇亲密伴侣暴力(IPV)。鉴于经历过 IPV 的女性中创伤后应激障碍(PTSD)的发病率很高,因此有必要考虑 PTSD 评估对这一人群的作用是否充分。因此,本研究旨在评估过去一个月版本的 DSM-5 创伤后应激障碍核对表(PCL-5)在经历过 IPV 的社区女性样本中的心理测量特性,该核对表是最广泛使用的创伤后应激障碍症状自我报告测量方法之一。参与者为 158 名在过去 6 个月中遭受过 IPV 的女性(年龄 = 40.14 岁,39.9% 为白人)。PCL-5 显示出良好的内部一致性(Cronbach's α = .97),其得分与理论上相关的结构(即 SCID-5 中的创伤后应激障碍症状计数、IPV 严重程度、药物使用、抑郁、焦虑和情绪失调)呈显著正相关;但是,其 30 天稳定性较差,r = .38,ICC = .55。PCL-5 对创伤后应激障碍诊断的判别能力是可以接受的,AUC = .74。21 分的临界值最大限度地提高了灵敏度(82.5%)和特异度(55.4%);这低于典型的临界值(即 31-33)。尽管 PCL-5 通常具有足够的心理测量特性,但研究结果表明,相对于其他遭受创伤的人群,PCL-5 对遭受 IPV 的女性的作用并不理想。PCL-5的分界点低于典型分界点表明,PCL-5可能会低估遭受IPV的女性中创伤后应激障碍的患病率。

期刊介绍: Journal of Traumatic Stress (JTS) is published for the International Society for Traumatic Stress Studies. Journal of Traumatic Stress , the official publication for the International Society for Traumatic Stress Studies, is an interdisciplinary forum for the publication of peer-reviewed original papers on biopsychosocial aspects of trauma. Papers focus on theoretical formulations, research, treatment, prevention education/training, and legal and policy concerns. Journal of Traumatic Stress serves as a primary reference for professionals who study and treat people exposed to highly stressful and traumatic events (directly or through their occupational roles), such as war, disaster, accident, violence or abuse (criminal or familial), hostage-taking, or life-threatening illness. The journal publishes original articles, brief reports, review papers, commentaries, and, from time to time, special issues devoted to a single topic.
