RESUMO
Behavior analysts have implemented and evaluated several antecedent strategies for treating pediatric feeding problems. The extent to which antecedent interventions are beneficial, however, is not yet clear. This review examines recent research in the Journal of Applied Behavior Analysis (2000-2012) that evaluated antecedent interventions. We found that the feeding diagnosis (food refusal vs. food selectivity) and presence of feeding-related medical conditions were related to the differential implementation of antecedent interventions.

Studies have evaluated a range of interventions to treat food selectivity in children with autism and related developmental disabilities. The high-probability instructional sequence is one intervention with variable results in this area. We evaluated the effectiveness of a high-probability sequence using 3 presentations of a preferred food on increasing acceptance in a child with autism who refused a few specific foods. The high-probability sequence increased acceptance of 3 foods. We then systematically faded the intervention for 2 foods.
