Development of an expert-rater assessment of trauma history in a high-risk youth forensic sample.

Exposure to childhood trauma is particularly prevalent among incarcerated juveniles. Although there is a growing understanding of the detrimental impact trauma exposure can have on child and adolescent development, childhood maltreatment can be very difficult to accurately measure. Integration of self-report trauma histories as well as supplemental file reports of trauma exposure may provide the most accurate estimate of experienced trauma among youth in correctional settings. The current study developed an expert-rated assessment of trauma that synthesizes self-report, as well as objective file information, using a sample of 114 incarcerated male juveniles. In addition to establishing scale factor structure, reliability, and validity, the current study provides additional evidence of the prevalence of trauma among incarcerated juveniles and reports on external correlates of the scale that are particularly relevant in correctional settings (e.g., psychopathic traits). These results suggest that the integration of both self-report and file material can be meaningfully used to assess traumatic symptomology.
