This Bulletin reports the results of a study that used the Voice DISC, a computerized, self-administered version of the Diagnostic Interview Schedule for Children (DISC), to screen for psychiatric disorders in youth newly admitted to juvenile assessment centers. The Voice DISC offers the following advantages for use in the juvenile justice system: minimal staff support requirements, immediate scoring that generates provisional diagnoses, and privacy that increases the likelihood of disclosure of sensitive personal information. This initial feasibility study demonstrates that a comprehensive, scientifically sound diagnostic instrument can be a valuable part of mental health assessment for youth in the juvenile justice system. Based on their findings and those of other researchers, the authors recommend best practices in assessing the mental health of juvenile offenders. This Bulletin provides guidance to juvenile justice professionals seeking to establish guidelines for mental health assessment in juvenile justice facilities. (Contains 5 tables and 8 endnotes.)
