Brown Bag Lecture Series

This presentation will evaluate the factor structure of the PTSD Checklist (PCL; Blanchard, Buckley, Forneris, & Jones-Alexander, 1996) in two large samples of persons with severe mental illness, including 1144 persons from five eastern states participating in a seroprevalence study of infectious disease, and 1021 persons from New Jersey who were screened for a treatment study for trauma. Five models of the structure of posttraumatic stress disorder (PTSD) symptoms in the PCL were tested using confirmatory factor analyses. The results indicate that a four-factor model composed of intrusion, avoidance, numbing, and hyper-arousal demonstrated the best fit. The findings provide some support for the conceptualization of four-symptom-clusters of PTSD in the DSM-5 in people with serious mental illness. Clinical implications and future directions will be discussed.
