It has been estimated that 70% to 90% of individuals diagnosed with autism spectrum disorder (ASD) experience mealtime challenges (Volkert & Vaz, 2010). Most approaches to the treatment of mealtime challenges have focused on decreasing interfering mealtime behaviors through escape extinction (i.e., requiring consumption of food prior to meal termination) and other approaches that may be perceived as punitive by parents, individuals diagnosed with ASD, and other stakeholders. In recent years, there has been an increase in research on promoting enjoyable mealtimes for individuals diagnosed with ASD and their families. The purpose of this edited book is to provide a comprehensive review of these approaches for improving mealtime behaviors for individuals diagnosed with ASD, provide clinical recommendations for improving mealtime behaviors, and identify areas for future research.
