A study on the simultaneous food presentation for food selectivity in a child with autism spectrum disorder

Abstract

The current study used the simultaneous presentation to increase target food intake and improve feeding categories and the Rohrer index in a child with autism spectrum disorder, who attended third grade at a special needs education school for the mentally challenged. She consumed smaller meal amounts than her age group and could eat only a limited variety of foods. The purpose of this study was to examine the effectiveness of antecedent manipulation for food selectivity and points to be considered for intervention. After general assessment and food selectivity evaluation, target foods were selected, in consultation with her mother. The intervention was typically conducted on the days when she attended the day care service center all day, and the lunch period was approximately 30-40 minutes. As a result, her intake of some target foods and side dishes increased and food variety was altered. The Rohrer index did not reach the age standard, but the improvement was seen after the intervention. The results suggested that simultaneous presentation intervention, a form of intervention based on antecedent manipulation, was effective.
