This study used experimental methodology to investigate the differential impact of various levels of sexual victimization on women's perceptions of risk and evaluative judgments of sexual assault within a dating interaction. Single- and multiple-incident victims were compared with nonvictims. Results supported the hypothesis that revictimized women would exhibit longer latencies than either single-incident victims or nonvictims in signaling that an audiotaped date rape should be halted. Revictimized women with greater posttraumatic stress disorder (PTSD) symptoms, arousal symptoms in particular, exhibited latencies similar to those of nonvictims, whereas revictimized women with lower levels of PTSD symptoms had significantly longer latencies. Dissociative symptoms were not related to latency. These findings suggest that PTSD-related arousal symptoms may serve a buffering effect, increasing sensitivity to threat cues that portend a sexually coercive interaction.
