In each facility, the moral discussion group process was compared with a placebo group that received a values clarification program, which was similar to the moral discussion group approach, and a control group, which received no treatment. The results indicated that the moral discussion group had a significant impact on the moral reasoning ability of delinquent and predelinquent adolescents as compared with a placebo group and a control group. The findings also indicated that gains in moral reasoning do not necessarily lead to improved classroom behaviors. (Author abstract)
