The subjects were 64 adolescents in juvenile probation hall in San Mateo County, California. Session One, participants answered the Childhood Trauma Questionnaire (CTQ), the Response Evaluation Measure for Youth-71 (REMY-71), and the Weinberger Adjustment Inventory. In Session Two, participants were given the Childhood Trauma Interview (CTI) and the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D). In the sample, 28.3 percent met criteria for a dissociative disorder and 96.8 percent endorsed a history of traumatic events. Significant positive correlations were found between CTI and CTQ trauma scores and SCID-D and REMY-71 dissociative symptoms. All dissociative symptoms were endorsed, but depersonalization was the most common experience. There was a lack of congruence between the different methods of assessing dissociation. The study provided support for an early link between history of trauma and dissociation. Adolescents were able to answer questions from a structured interview assessing dissociation. 26 references, 3 tables, and 1 figure
