The present study evaluated the effectiveness of an interdependent group contingency commonly referred to as the “good behavior game” (GBG) on reducing disruptive behaviors in a dedicated classroom for students with emotional behavioral disorder (EBD). The participants were four eighth-grade middle school students, with a primary diagnosis of EBD. The intervention targeted inappropriate and disruptive behaviors during two class periods (math and science), as well appropriate alternative behaviors. The class was divided into two teams, with the four participants divided evenly amongst both teams. If a team met the criterion for both inappropriate and appropriate behavior during experimental sessions, each team member received an edible reinforcer (candy). In addition, teams that met the weekly goal of winning the most games earned a trip to a classroom with younger peers to participate in a social activity (pizza party, movie and popcorn, etc.). The results indicated a decrease in inappropriate behaviors, as well as an increase in appropriate behaviors. The results suggested that the GBG is a beneficial group interdependent contingency that can be implemented in many classroom settings, including an alternative EBD middle school classroom. .
