Abstract

Background

Posttraumatic stress disorder (PTSD) is common after traumatic injury, negatively impacting recovery. Black Americans face elevated PTSD risk following traumatic injury, yet diagnostic accuracy of assessments in trauma center settings serving this population is unknown. The Posttraumatic Stress Disorder Checklist for DSM-5 (PCL-5) exhibits strong psychometric properties but optimal cut-scores by race require examination.

Methods

Data were combined from three ongoing projects of injured Black American adults (N = 270). Participants completed the PCL-5 and Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) six months post-injury. Receiver operating characteristic analysis determined the PCL-5's diagnostic utility against the CAPS-5. Sensitivity, specificity, predictive values, and diagnostic efficiency were calculated across cut scores.

Results

Prevalence of CAPS-5 PTSD at 6-months post-injury was 34.4 %. The PCL-5 demonstrated good accuracy in detecting PTSD (AUC=.931). A PCL-5 cut-score of > 33 maximized diagnostic efficiency (89.1 %), with sensitivity of 89.1 % and specificity of 87.6 %.

Conclusions

The PCL-5 is an accurate PTSD screening tool for injured Black Americans using an appropriate threshold. Findings have implications for improving mental health care access in trauma settings serving marginalized groups.

PCL-5在创伤性黑人人群中的诊断价值

背景创伤后应激障碍（PTSD）在创伤后很常见，对康复有负面影响。美国黑人在创伤性损伤后面临较高的创伤后应激障碍风险，但在为这一人群服务的创伤中心设置中，诊断的准确性尚不清楚。DSM-5的创伤后应激障碍检查表（PCL-5）显示出很强的心理测量特性，但种族的最佳分值需要检查。方法将三个正在进行的美国黑人成人受伤项目的数据合并（N = 270）。参与者在受伤后6个月完成了DSM-5的PCL-5和临床管理的PTSD量表（CAPS-5）。接受者工作特征分析确定了PCL-5对CAPS-5的诊断效用。敏感性、特异性、预测值和诊断效率通过切口评分进行计算。结果伤后6个月cap -5型PTSD患病率为34.4% %。PCL-5在诊断PTSD方面具有较好的准确性（AUC= 0.931）。PCL-5 cut-score为>； 33，诊断效率最高（89.1% %），敏感性为89.1% %，特异性为87.6% %。结论PCL-5是一种准确的创伤后应激障碍筛查工具，具有合适的阈值。研究结果对改善为边缘群体服务的创伤环境中获得精神卫生保健的机会具有启示意义。

期刊介绍： The Journal of Anxiety Disorders is an interdisciplinary journal that publishes research papers on all aspects of anxiety disorders for individuals of all age groups, including children, adolescents, adults, and the elderly. Manuscripts that focus on disorders previously classified as anxiety disorders such as obsessive-compulsive disorder and posttraumatic stress disorder, as well as the new category of illness anxiety disorder, are also within the scope of the journal. The research areas of focus include traditional, behavioral, cognitive, and biological assessment; diagnosis and classification; psychosocial and psychopharmacological treatment; genetics; epidemiology; and prevention. The journal welcomes theoretical and review articles that significantly contribute to current knowledge in the field. It is abstracted and indexed in various databases such as Elsevier, BIOBASE, PubMed/Medline, PsycINFO, BIOSIS Citation Index, BRS Data, Current Contents - Social & Behavioral Sciences, Pascal Francis, Scopus, and Google Scholar.
