Food selectivity and other mealtime problems are common in children diagnosed with autism spectrum disorder (ASD). Food selectivity can interrupt appropriate development and lead to disruptive behaviors and familial stress. Escape extinction, a common intervention, can lead to more undesirable behaviors, more health concerns, and fails to teach independent eating skills. This study aimed to treat food selectivity in 2 children diagnosed with ASD by modeling and shaping independent initiations (i.e., tolerating, interacting, tasting, and eating) to food items. A nonconcurrent multiple baseline across participants design evaluated the effects of the intervention while measuring the participant’s affect throughout the mealtimes. The results indicated that this approach increased food-related responses and provided a positive mealtime experience for both participants.
