The domain of restricted and repetitive patterns of behaviors and interests (RRBI) is a core diagnostic feature of autism spectrum disorder (ASD). This group of heterogeneous symptoms shares a common characteristic of inflexibility. RRBI are pervasive, inappropriate and associated with emotional difficulty and problem behaviors. Higher-order RRBIs, in particular, pose an increasing interference as children continue to develop. The current study examines the effects of implementing an individualized self-management intervention to increase behavioral flexibility. A multiple baseline research design was implemented. Results indicate the intervention was associated with increased percentages of behavioral flexibility, improvements in child affect ratings, and generalization of behavioral gains to a variety of settings and activities.
