Student behavior is a major concern for all teachers as classroom management is key to improving educational outcomes. Despite many schools utilizing punitive strategies, research suggests that positive behavior intervention supports (PBIS) are more appropriate and effective at improving student behavior. One such intervention, the Good Behavior Game (GBG) has a long history as an evidence-based practice for school aged children, including those with emotional and behavioral disorders (EBDs). While the research supporting the GBG is robust, less is known about the maintenance effects of this intervention. Maintenance effects are defined as the persistence of treatment effects across time. Studies have demonstrated lasting effects of the GBG and that student behavior maintained when the GBG was used less frequently. However, the more immediate effects of the GBG remain unknown, which may be important for how teachers plan and structure their school day. The present study utilized a single subject reversal design across two classrooms to demonstrate the effectiveness and maintenance effects of the GBG on students with EBDs within an instructional period. Specifically, this study examined the maintenance of student on-task behavior, student problem behaviors, and teacher praise-to-reprimand ratios immediately following removal of the GBG. The results indicate that the GBG was effective in improving student on-task behavior, decreasing student problem behaviors, and increasing teacher praise-to-reprimand ratios and that the effects maintained within the instructional period. Overall, students remained on-task and had lower rates of problem behaviors immediately following the removal of the GBG within the class period. Teachers also maintained higher praise-to-reprimand ratios during the maintenance portion of the instructional period.
