The current literature on self-monitoring provides limited information on increasing functional communication skills in students with disabilities by incorporating function-based intervention. The purpose of this study was to extend self-monitoring literature by incorporating functional communication training (FCT) into self-monitoring intervention and targeting students who engage in problem behavior due to communication difficulties. Three students with disabilities served in kindergarten through 3rd grade and their corresponding teachers participated in this study. A multiple baseline across participants design with an ABC sequence was used to investigate the impact of function-based self-monitoring (SM) with FCT only and function-based SM with FCT augmented with differential reinforcement of alternative behavior (DRA) on student functional communicative behavior, academic engagement, and problem behavior. The results indicated that the function-based SM with FCT was effective in increasing functional communicative behavior and academic engagement behavior and decreasing problem behavior for all participating students. The addition of DRA further improved behavioral outcomes for one student. Results were maintained for three participants while fading the magnitude of the intervention. Students and teachers rated the function-based SM treatment package as effective and acceptable.
