Validity of the Reiss Screen for Maladaptive Behavior.

The validity of the subscales of the Reiss Screen for Maladaptive Behavior in an institutional population was examined by correlating these scores with the Psychopathology Instrument for Mentally Retarded Adults (PIMRA), the Aberrant Behavior Checklist, and programmatic measures, such as psychiatric diagnoses, psychotropic medication, behavior therapy programs, and presence on a dual diagnosis unit. Results of this study broadly replicated the previous research on the validity of the Reiss total score. Evidence for the validity of the subscales was more limited, possibly due to limitations in the internal consistency of the Reiss or PIMRA subscales.
