Abstract

Prior research shows discrepant findings in relation to psychophysiological reactivity to threat in women with histories of sexual victimization. Women ages 18 to 22 (N = 123) with histories of sexual abuse were categorized into child sexual abuse (CSA), adult sexual victimization, revictimization, or nonvictimization groups. Low- and high-frequency heart rate variability were measured at baseline and during an Emotional Stroop task of abuse-related words. Revictimized women showed a significant decrease from baseline to task in both parasympathetic and sympathetic measures when compared to the CSA group. The CSA group demonstrated chronic sympathetic activation at both baseline and task, relative to the revictimization group. Groups did not differ on performance (i.e., reaction time) on the Emotional Stroop task (i.e., more threatening stimuli, slower performance). Cardiovascular responses reported might point to biological reactivity patterns needed for women with a history of sexual abuse to cope with abuse-related stimuli.
