A multiple baseline design study was implemented to assess the effects of a modified social story intervention on inappropriate social behaviors of three adolescents with moderate autism. Baseline data were collected on inappropriate behaviors that included refusal to stand, use of a high-pitched voice, and placing hands/objects in mouth. Individualized social stories, ranging from five to seven pages and containing text, color photographs, and callouts, were created for each student. Results suggest that social stories immediately improved behavior for two of the participants and these improvements were maintained. Information is also provided regarding teacher opinion on the use of social stories. Implications for training and future research are discussed. (Contains 3 tables and 1 figure.)
