About

The Autism Managing Eating Aversions and Limited variety (MEAL) Plan is a group-based parent training intervention designed to assist parents in increasing the variety of foods eaten in children with Autism Spectrum Disorder (ASD). The goal of the Autism MEAL Plan is to include specific techniques to manage mealtime behavioral challenges and introduce new foods.

Full description

The Autism Managing Eating Aversions and Limited variety (MEAL) Plan is a structured parent-mediated, group-based intervention to reduce mealtime disruptive behavior, expand dietary diversity and reduce parental stress associated with moderate food selectivity in young children with Autism Spectrum Disorder (ASD).

Children ages 3-8 with a diagnosis of ASD who present with moderate food selectivity and associated problem behavior will be screened for inclusion in the study. Following consent and screening procedures, parents of eligible children will be assigned to a group-based parent training (Autism MEAL plan) or group-based parent education. Each parent will receive 1.5 hours of intervention per week for 10 weeks by a masters or doctoral level clinician.

Data will be collected on parental compliance with the Autism MEAL plan and the food acceptance of the child as well as nutritional intake, and refusal behaviors. Child participants will also be included in parent-child dyad in-vivo feedback sessions. Parents assigned to parent education will be able to cross-over to receive the Autism MEAL Plan following completion of post-study measures.

The first aim of the study is to finalize the Autism MEAL Plan materials (e.g., role-play activities, activity sheets and video examples). This includes standardizing therapist scripts in line with the revised curriculum and creating new video examples that coincide with practice worksheets. Home recording (e.g., personal camera phone) to document and present home meal data will also be added to the curriculum.

The second aim is to evaluate the feasibility of the Autism MEAL Plan versus parent education in 40 children (20 per treatment assignment) with ASD and moderate feeding problems.

The final study aim is to evaluate the preliminary efficacy of the Autism MEAL Plan in expanding food diversity, decreasing disruptive behavior and reducing parental stress compared to Parent Education. Methods of evaluating this aim include direct observation, parent ratings of behavior, food intake and stress, as well as blinded clinician ratings, height, weight and BMI.

• Presents with a history of moderate food selectivity (a diet involving at least 6 food items)
• Accepting at least one fruit or vegetable
• Fewer than two food items in one or more food categories (i.e., fruit, vegetable, protein, starch) as measured by the Food Preference Inventory
