This study was an attempt to replicate an earlier investigation in which parents were trained to alter the behaviors of their aggressive children. 11 consecutive referrals from community agencies received an average of 31.7 hours of professional time. Multiplecriteria were used to evaluate treatment outcome. Observers collected systematic data in the homes during baseline and intervention. At termination these data showed significant reductions in deviant child behaviors. Parents provided daily reports on the occurance of selected problem behaviors. These data showed moderate reductions at termination. Some time after termination parents were called and asked for global evaluations. All parents reported marked improvements in the behavior of the children. The findings are viewed as a replication of earlier findings.
