Neuropsychological assessment of brain damage: discriminative validity of the McCarron-Dial System.

The purpose of this study was to investigate the discriminative validity of the McCarron-Dial System (MDS) in neuropsychological assessment. Multiple discriminant analysis results indicate that 92.6% of the brain-damaged and non-brain-damaged groups, and 69.6% of the right, left and diffused brain-damaged subgroups were correctly classified using the abbreviated version of the MDS. The results tentatively support the discriminative ability of the MDS for neurobehavioural diagnosis. Since the MDS has a long tradition in vocational rehabilitation and established strengths in predicting vocational and community adjustment outcomes, it may be potentially useful for both vocational and clinical neuropsychological assessment.
