Measurement invariance of the PTSD checklist for the DSM-5 (PCL-5) in a veteran sample.

ABSTRACT: The PTSD checklist for the DSM-5 (PCL-5) is among the most widely used measures of posttraumatic stress disorder (PTSD) symptoms. Although its psychometrics are well studied, the measurement invariance properties of the PCL-5 have not yet been closely examined. This study examined the measurement invariance properties of the PCL-5 across gender and racial (Black, White) categories using a nation-wide sample (N = 1,357, 51% women, 18% Black) of post-9/11 Army and Marine Corps veterans overselected for PTSD symptoms. PTSD was modeled within a higher order factor structure using observed PCL-5 responses as ordered polytomous data. We examined group-level invariance across item response thresholds and first- and second-order factor loadings and intercepts. We used 500 bootstrapped racia
