DSM-5 （PC-PTSD-5）初级保健PTSD筛查的性质和效用在社区人群中尚未研究。本研究在美国东南部的一家大型公立医院评估了PC-PTSD-5的表现，以确定它是否可以作为DSM-5 （PCL-5）的PTSD检查表的简短替代。参与者（N = 422人，黑人92.7%，女性85.8%，年龄42.0岁，年龄13.4岁）从门诊候诊室和住院名单中招募后完成了PCL-5和PC-PTSD-5。使用机会校正测试质量指数和项目反应理论（IRT）分析，我们确定了筛选和检查项目性能的最佳切割分数。约45.0%的样本在使用PCL-5筛查时可能为DSM-5 PTSD阳性。PC-PTSD-5表现出较高的内部一致性，与PCL-5得分有较强的相关性（总r = 0.79，单项r = 0.51 ~ 0.61）。cut-score为1对筛选（κ[1] =）最敏感。在PCL-5上检测自我报告的DSM-5 PTSD时，cut-score为4具有最高的可能效率质量（κ[.5] = .66）。IRT分析表明，项目1（噩梦，侵入性记忆）提供了最多的信息，而其他项目可能不会对这个样本逐渐有用。研究结果为在公共医疗机构中使用PC-PTSD-5作为慢性创伤暴露患者PCL-5的简短替代提供了初步支持。
The properties and utility of the Primary Care PTSD Screen for DSM-5 (PC-PTSD-5) remain unstudied in community-based populations. This study evaluates the performance of the PC-PTSD-5 to determine whether it can be used as a brief alternative to the PTSD Checklist for DSM-5 (PCL-5) in a large public hospital in the southeastern United States. Participants (N = 422; 92.7% Black; 85.8% female; Mage = 42.0 years, SDage = 13.4 years) completed the PCL-5 and PC-PTSD-5 after recruitment from medical clinic waiting rooms and admission lists. Using chance-corrected test quality indices and item response theory (IRT) analyses, we determined optimal cut-scores for screening and examined item performance. Approximately 45.0% of the sample screened positive for probable DSM-5 PTSD using the PCL-5. The PC-PTSD-5 demonstrated high internal consistency and strong associations with PCL-5 scores (total, r = .79; items, rs = .51–.61). A cut-score of one was optimally sensitive for screening (κ[1] = .96), and a cut-score of four had the highest quality of probable efficiency (κ[.5] = .66) for detecting self-reported DSM-5 PTSD on the PCL-5. IRT analyses indicated Item 1 (nightmares, intrusive memories) provided the most information, and other items may not be incrementally useful for this sample. Findings provide preliminary support for the use of the PC-PTSD-5 as a brief alternative to the PCL-5 among chronically trauma-exposed patients in the public healthcare setting.
