Notwithstanding the wealth of research that documents the effectiveness of self-management programs in the classroom, few investigations have explored classwide use of self-management procedures as a universal intervention. To extend existing research in this area, we examined the effectiveness of a classwide self-management intervention for decreasing disruptive behaviors among three at-risk second-grade students. We used a multiple baseline across subjects design and evaluated the effects of the self-management program at both the individual and classwide levels during academic instruction time. Results of the study showed a decrease in disruptive behaviors of the target students and a general decrease in classroom disruptive behavior. In addition, teachers and students provided positive ratings of intervention acceptability and feasibility. Limitations, implications, and future directions for research are discussed.
