We evaluated the effects of a multicomponent intervention to address food selectivity issues of 3 preschoolers with developmental disabilities. The intervention comprised strategies evidencing ecological validity in both research and practice. All sessions took place during typical mealtimes in children’s classroom or lunchroom, with peers present, and a school-based staff member serving as the instructor. A multiple probe design across behaviors (touch, smell, taste, and eat), with a nested changing criterion design in the final tier, was used to evaluate changes in eating behaviors (author abstract)
