A plethora of literature suggests that collaborative partnerships among families, educators, and outside service providers are necessary and beneficial to address behavior problems, but there continues to be a lack of coordination among these stakeholders. The current study used conjoint behavioral consultation (CBC) to facilitate the development and implementation of collaborative intervention plans. Parents, teachers, and an outside mental health provider worked together to create and support behavioral intervention plans that were implemented at home and school. The results of this multiple baseline study indicate that collaborative interventions developed through the CBC process were effective in improving behavior at home and school. More specifically, visual analysis of the data, along with calculated effect sizes, showed an increase in the percentage of time that all 3 participants complied with expectations during problematic routines at home and school. Implications, limitations, and future research directions are discussed.
