An investigation of the intellectual capabilities of juvenile offenders.

One hundred two cases were drawn randomly from the Bronx Family Court Mental Health Clinic's active files. Clients were given a Wechsler Intelligence Scale for Children--Revised, Bender Gestalt, and Wide-Range Achievement Test Reading. Results indicated that approximately one third were functioning the mentally defective range, one third in the borderline mentally retarded range, and one third in the low average to average range. Almost half showed perceptual deficits correlated with minimal brain dysfunction. Results were highly significant, suggesting that delinquents apprehended and seen in our clinic are likely to be of borderline intelligence or below, showing evidence of minimal brain dysfunction. Hypotheses are discussed, as is the need for appropriate treatment facilities.
