The present investigation examined the effectiveness of a cognitive behavioral treatment program designed for sexually abused children suffering post-traumatic stress disorder. Nineteen girls who suffered contact sexual abuse and met DSM-III-R criteria for post-traumatic stress disorder were included in the study. Subjects ranged in age from 3 to 16 years old. Structured interviews were conducted to assess the presence or absence of post-traumatic stress disorder symptoms before, during, and following the abuse. Additionally, parents completed the Child Behavior Checklist, and subjects at least 6 years of age were administered the Child Depression Inventory and the Spielberger State-Trait Anxiety Inventory at the initial evaluation and again approximately 2 to 3 weeks later before the initiation of treatment. The baseline data collected at these two points were compared, and no significant changes were found over time. The above measures were readministered following 12 treatment sessions. The results revealed significant improvements at post-treatment on all measures.
