Information came from 90 individuals who had been ordered to group counseling in the Northern District of Alabama as a requirement of their probation supervision. They were scheduled for one, 3-hour session each week for 13 weeks. The group counseling was modeled on Maxie Maultsby's theory of rational behavior training. The individuals were classified into minimum, medium, or maximum supervision categories according to common traits measured in the Federal probation system. Findings showed that success on probation was directly related to the level of participation in the program, but that the groups performed exactly as predicted before counseling. Thus, the mandatory group counseling had no proven effect on the statistically predicted behavior of offenders. Tables and 13 references.
