Interpersonal difficulties mediate the relationship between child sexual abuse and depression symptoms.

This study examined the influence of interpersonal functioning as a mediator in the relationship between child sexual abuse and depression symptoms, after accounting for the influence of child physical abuse. The research questions build on the existing knowledge base by examining mechanisms of adult adjustment among child sexual abuse survivors. In the current study, 2,892 young adult women (18-29 years old; M = 19.06) reported on child sexual and physical abuse, 5 domains of interpersonal functioning, and depression symptoms. The results supported aggression, sensitivity, ambivalence, and lack of sociability as mediators in the relationship between child sexual abuse and depression symptoms. These results suggest that interpersonal difficulties related to hostility, emotional reactivity, inability to collaborate, and isolation may be of particular interest when understanding depression in child sexual abuse survivors. The findings support interpersonal problems as a key mechanism of depression symptoms following child sexual abuse and is even demonstrated when examining long-term outcomes and controlling for child physical abuse. The hypotheses and findings are discussed in the context of interpersonal psychotherapy for depression.
