HIV and PTSD: A Confirmatory Factor Analysis of the PCL Screening Instrument

ABSTRACT

The findings are reported from a confirmatory factor analysis (CFA) of the posttraumatic screening checklist (PCL) created by Weathers et al. (1993) Weathers, F. W., Litz, B. T., Herman, D. S., Huska, J. A. and Keane, T. M. 1993. The PTSD Checklist (PCL): Reliability, validity, and diagnostic utility, Presented at Annual Meeting of the International Society for Traumatic Stress Studies, San Antonio, TX. [Google Scholar]. One hundred and eighty-six individuals receiving either preventive HIV information or ongoing HIV counseling from community-based AIDS organizations in the New York City area completed the PCL checklist. To identify a model relevant to screening posttraumatic stress disorder (PTSD) within the HIV/AIDS community, six CFAs were conducted. Results indicated that the PTSD scale should include attention to four general areas: a) reexperiencing the traumatic event; b) avoidance of anything associated with the traumatic event; c) a sense of numbing; and d) a hyperarousal state. The CFA produced a more concise model of 12 items, relevant to the HIV community. Future research suggests that the relationships between different components of trauma exposure and different manifestations of PTSD should be examined further.
