Convergent validity of three posttraumatic symptoms inventories among adult sexual abuse survivors

Abstract
We examined the convergent validity of three posttraumatic symptoms inventories, the civilian version of the Mississippi Scale for Combat-Related PTSD (CM-PTSD), the Trauma Symptom Checklist-40 (TSC-40), and the Response to Childhood Incest Questionnaire (RCIQ), in a sample of 52 adult sexual abuse survivors. The significant and moderate to strong correlations (r = .6 or higher) among these inventories supported their convergent validity. Comparison with other studies also suggests that these instruments can adequately discriminate clinical from nonclinical populations
