Abstract
Objective: The purpose of this study was to test the diagnostic validity of the Primary Care PTSD screen (PC-PTSD) in a generalizable college sample and to examine potential differences in its predictive efficacy according to sex and racial/ethnic identity. An exploratory aim was to determine whether PC-PTSD symptom items differentially predicted PTSD diagnostic status. Participants: Data from 475 undergraduates were analyzed. Methods: Logistic regressions were conducted to examine the relationship between different PC-PTSD endorsement thresholds and probable PTSD among various subsamples. Follow-up tests of diagnostic accuracy were performed. Results: Results of this study indicated that the PC-PTSD identified PTSD among college students with poor accuracy. Furthermore, the PC-PTSD did not demonstrate equal predictive validity across neither sex nor racial/ethnic identity. Endorsement of reexperiencing symptoms appeared to be the strongest predictor of PTSD. Conclusions: Results highlight the clear need for a validated PTSD screener effective for a diverse college population.
