Abstrakt: 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.
