Abstract

Children with autism are frequently labeled as selective or “picky” eaters (Volkert & Vaz, 2010). The purpose of the current study was to evaluate antecedent choice as an intervention for decreasing selective eating in children diagnosed with autism. The results show that choice as an antecedent intervention was not effective at increasing consumption of non-preferred foods for three children diagnosed with autism. Acceptance of non-preferred food was 0% in baseline for all participants and remained at 0% during choice between two non-preferred foods. A differential reinforcement of alternative behavior (DRA) component was added to the choice phase, but acceptance of the non-preferred bite remained at 0%. Discussion on possibilities for treatment failure and alternative interventions is provided.
