Abstract
This study investigated the effects of marathon group counseling on the attitudes of imprisoned male illicit drug users. Residents selected randomly into a control and an experimental group responded to a semantic differential which included the following concepts: Kindness, Anger, Guilt, Reality, My Real Self, The Future, Drug Treatment Programs, Counselors, Counseling, and Group Counseling. The scores of the control and marathon group participants were compared on posttests by t-tests. The posttest scores of the marathon group participants were significantly higher than the scores of the control group participants on the following scales: Counselor (E), Group Counseling (E), and Drug Treatment Programs (P).
