The purpose of this study was to compare the effectiveness of two models of adolescent drug treatment on parenting practices. The data for this study was collected using a randomized treatment evaluation design over a six month period. The sample consisted of adolescent substance users and their parents who have been referred to the Adolescent Health and Resource Center. Data was collected from GAIN assessments that have been completed by the adolescent and his/her parent at baseline and six months. The data was analyzed with an evaluative statistical design. The results of the study failed to support the hypotheses. There were no significant differences in changes in parenting practices between the Seven Challenges and SOFT family therapy model. On the other hand, there were significant relationships between hours of therapy and positive behavior changes. Overall, the study found there was no significant difference between family and non-family based therapy on parenting practices. The limitations make it difficult to generalize the larger population.
