This article reviewed behavioral treatment of restricted and repetitive behavior and interests (RRBIs) specifically for children with autism spectrum disorder (ASD) 8 years of age and younger. Empirical studies published in the last decade that examined the effects of behavioral interventions for RRBIs in young children with ASD were reviewed. Electronic database and ancestral searches identified 31 studies meeting inclusion criteria (104 participants). Results indicated antecedent-based interventions were the most common for lower-order RRBIs (L-RRBIs), while multicomponent treatment packages were the most common for higher-order RRBIs (H-RRBIs). Consequence-based strategies were more effective in decreasing L-RRBIs. Few studies examined H-RRBIs and natural change agents were seldom included in RRBI interventions. Limitations and implications for future research were discussed.
