Posttraumatic stress disorder in a clinical sample of adults sexually abused as children.

Forty-seven help-seeking, adult survivors of childhood sexual abuse (CSA) were assessed to examine the relationship between the level of CSA exposure and the subsequent development of posttraumatic stress disorder. CSA exposure was operationalized to include the overall level of exposure, frequency and duration of the abuse, age of onset, use of force, perceived life threat, and the occurrence of penetration. Participants were administered standardized measures of PTSD, including the Structured Clinical Interview of DSM-III-R (SCID). On the SCID, 69% of the survivors met full DSM-III-R criteria for PTSD. Significant correlations were found between several overall exposure measures and PTSD diagnostic status and the intensity of PTSD symptomatology. Similar relationships were identified with the duration and frequency of the abuse, the age of onset, and the use of force. This study is important in that it utilized standardized measures of PTSD and found a significant incidence of PTSD among adult CSA survivors.
