Abstract

The prevalence of posttraumatic stress disorder (PTSD) was evaluated in 91 participants attending a community-based substance abuse program. The participants were classified as having PTSD, possible PTSD, or no PTSD using the modified PTSD symptom scale (MPSS; Falsetti, Resnick, H. S., Resnick, P. A. & Kilpatrick, 1993). These groups were then compared on measures of anxiety, depression, and fear using the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Anxiety Sensitivity Index (ASI), and the Fear Questionnaire (FQ). The results showed that 52.8% of participants had either PTSD (37.4%) or possible PTSD (15.4%). Findings also showed that those with PTSD experienced more potentially traumatic events (e.g., rape, being beaten-up) compared to the possible PTSD and no PTSD participants. The PTSD group also reported significantly greater scores on the ASI, BAI, and BDI than did the no PTSD group, and greater scores on the ASI and BAI than did the possible PTSD group. Further, when using a discriminant function analysis, self-report measures correctly classified 70% of the PTSD group and 80% of a composite group of possible PTSD and no PTSD participants. Implications of these results are discussed.
