The Aggression and Violence Reduction Training Program (AVT) was implemented with African-American adolescent males referred by probation officers and judges in the Fulton County Juvenile Justice System in Atlanta, Georgia. Twenty-one adolescent males comprised the purposive sample of this research study. The treatment group consisted of ten adolescent males and the control group consisted of eleven adolescent males. The AVT was an eight session program that utilized cognitive-behavioral techniques to reduce low to moderate levels of aggression and violence in adolescent African-American males. The program/intervention addressed social skills training, anger management, and violence education through such methods as group activities, discussions, handouts, video presentations, homework, role playing activities, facilitator feedback, and group feedback. The study utilized a quasi-experimental non-equivalent control group design to evaluate efficacy of the intervention. Questionnaires were completed by the youth and their parent or caregiver at pre and post-testing. The youth completed the Conners-Wells Adolescent Self-Report Scale (CASS) and the Aggression Questionnaire (AQ). The parent or caregiver completed the Conners Parent Rating Scales-Revised (CPR-R) and a Behavioral Questionnaire (BQ). Data collected were analyzed using the independent-samples t-test and the paired-samples t-test. Based on the results of the independent-samples t-test, the groups were not found to be statistically significantly different on the pretest prior to the intervention. After the intervention, statistical significance was found based on the results of two of the four measures; the CASS completed by the youth and the BQ completed by the parent/guardian. Differences in the control group were not observed. Of four hypotheses, two were fully substantiated and two were partially substantiated.
