Abstract:  Adolescence can be a time of extremes; a time that may cause difficulties that result in mental health problems. Of the mental health problems faced by adolescents, disruptive behavior disorders are the most frequently diagnosed. Adolescents with disruptive behavior disorders may have problems exhibiting prosocial behaviors. Sport is one forum in which adolescents can develop prosocial behaviors; however, sport alone does not guarantee such development. Opportunities must be present for learning prosocial behavior in addition to sport skills. This investigation examined effects of a six-week prosocial behavior intervention provided during basketball instruction on the behavior of five adolescents with disruptive behavior disorders. A single-subject, multiple baseline across behaviors design was used to assess the intervention’s impact on prosocial behaviors (encouraging, helping, and resolving conflicts), and antisocial behaviors (physical aggression and verbal aggression). Behaviors were observed during basketball games and occurrences were plotted on graphs. To establish reliability, a secondary observer viewed 20% of the videotapes and recorded behaviors. Using a gross method of agreement, the percentages of 91%, 98%, 100%, 88%, and 75% were obtained for five tapes. Hypotheses stated that participants would demonstrate an increase in prosocial behaviors and a decrease in antisocial behaviors when compared to baseline behavior. Based on a level change immediately following initiation of the intervention for the behaviors of encouraging and helping, and higher mean values maintained during intervention and follow-up for encouraging and conflict resolving, it appeared that the intervention had a minimal effect on the participants behavior. However, since replication of effects was not observed across behaviors, support for the efficacy of the intervention is limited. In addition, because prosocial behaviors decelerated during the intervention and there was a lack of maintenance of the behaviors, maintenance of effects of the program was not supported. The intervention did not appear to influence antisocial behavior. Based social validity questionnaire responses, a video-viewing component was added. Limitations include variable data, decelerating trends, lack of maintained effects, inconsistent effects of the intervention, and limited replication of data. Recommendations include extending the length of the intervention, providing additional sports to maintain participants’ interest, and including instructional units designed to decrease antisocial behaviors.
