Fractured Pasts: The Structure of the Life Story in Sexual-Trauma Survivors With Posttraumatic Stress Disorder.

Abstract

We examined the organization of past and future affective autobiographical knowledge in sexual-trauma survivors compared with control participants. Participants (N = 113) divided their past (and future) life into chapters (e.g., "college," "marriage"), then characterized each chapter using positive or negative attributes. Sexual-trauma survivors (n = 27) endorsed a greater proportion of negative attributes, demonstrated greater affective compartmentalization (separation of positive and negative attributes into different chapters), and showed reduced redundancy (consistent endorsement across chapters) of positive attributes relative to control participants (n = 23). Groups did not differ on negative redundancy for past life structure or any metrics for future life structure. In a secondary analysis, we compared life structures for the sexual-trauma group and for individuals with chronic depression but no sexual-trauma history (n = 30) and matched control participants (n = 56), which revealed significantly greater negative redundancy in the depressed group. The distinct life structure presented by sexual-trauma survivors may reflect efforts to constrain the impact of trauma on an individual's self-identity.
