Behavior analysts have evaluated a wide range of assessment and treatment strategies in the area of feeding disorders. However, little is known about the effects of interventions employing peer modeling. This study extends upon the existing research on peer modeling and differential reinforcement with a 9-year-old boy diagnosed with autism who engaged in food selectivity. Using a non-concurrent multiple baseline design the effects of the treatment package were demonstrated across three foods. Moreover, a parent implemented phase demonstrated that the child's parent could use this package in a naturalistic manner and that treatment effects maintained at post 1-month follow-ups. Implications for future research in the area of peer-modeling and food selectivity are provided. (Contains 3 notes and 1 figure.)
