The concurrent validity of the Devereux Scales of Mental Disorders

The present study was designed as an initial investigation of the concurrent validity of the Devereux Scales of Mental Disorders (DSMD; Naglieri, LeBuffe, & Pfeiffer, 1994) in relation to the Behavior Assessment System for Children (BASC) and the Child Behavior Checklist (CBCL) in two clinically referred samples of children and adolescents. The DSMD is a recently published multidimensional behavior rating scale comprised of empirically and conceptually derived scales designed to aid the diagnostic decision-making process for youth with severe psychiatric and educational classifications. To date, no published study has examined the concurrent validity of the DSMD. The first of the present studies compared the DSMD and BASC with 64 children and adolescents in an inpatient hospital setting; the second study compared the DSMD and CBCL with 74 children and adolescents classified as having serious emotional disturbance (SED) in residential care. Concurrent validity was assessed through correlations and squared semipartial correlation coefficients between the DSMD scale scores and the BASC and CBCL, scale scores. Paired t tests (p <.001) were also computed across scales of similar constructs. In comparison to the BASC and CBCL, the DSMD demonstrated strong concurrent validity between conceptually similar scales, providing some evidence for the concurrent validity of the DSMD. Specifically, relative to the other measures, the DSMD appears to have some unique scales designed to detect more acute or serious pathology, whereas the BASC and CBCL may be better equipped to assess specific types of externalizing symptoms.
