A prospective examination of post‐traumatic stress disorder in rape victims

Abstract

Abstract Post‐traumatic stress disorder (PTSD) and related psychopathology were examined in 95 female rape victims beginning soon after the assault (mean = 12.64 days). Subjects were assessed weekly for 12 weeks. Ninety‐four percent of women met symptomatic criteria for PTSD at Assessment 1, decreasing to 65% at Assessment 4 (mean = 35 days postassault), and 47% at Assessment 12 (mean = 94 days postassault). PTSD and related psychopathology decreased sharply between Assessments 1 and 4 for all women. Women whose PTSD persisted throughout the 3‐month study did not show improvement after the fourth assessment; women who did not meet criteria for PTSD 3 months postassault showed steady improvement over time. This pattern was evidenced even after initial PTSD severity was statistically controlled. Moreover, PTSD status at 3 months postassault could be predicted with a high degree of accuracy by two brief self‐report measures administered at the first assessment. The implications of the present findings and directions for future research are discussed.
