Diagnostic Efficiency of the Personality Assessment Inventory LOGIT Function for Posttraumatic Stress Disorder in Women

Abstract

In this study, we examined the diagnostic efficiency of the Personality Assessment Inventory (PAI; Morey, 1991) for the assessment of posttraumatic stress disorder (PTSD) in a community-based sample of women (n = 128). Receiver operating characteristic curves (ROC) were generated to examine the efficiency of the PAI PTSD LOGIT function as a tool for diagnosing PTSD. Using the Clinician Administered PTSD Scale as the reference standard, the PTSD LOGIT function performed well (area under the curve [AUC] = .856, standard error [SE] = .034). This represents performance consistent with more commonly used self-report PTSD scales, the Davidson Trauma Scale (AUC = .863, SE = .033) and the PAI Anxiety subscale Anxiety-Related Disorders Traumatic Experiences (AUC = .861; S.E. = .033). Results of this study suggest that the PAI PTSD LOGIT function may be a useful tool in assessing PTSD.
