Autism MEAL Plan: Parent Training to Manage Eating Aversions & Limited Variety

Study Overview
=================
Brief Summary
-----------------
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.

Detailed 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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Autism MEAL Plan<br>Parents of eligible children who are randomized to the Autism Managing Eating Aversions and Limited variety (MEAL) Plan will participate in group-based parent training sessions (4 parents per group). | Behavioral: Autism MEAL Plan<br>* The Autism MEAL plan includes education on feeding issues and behavior management, and specific strategies to expand dietary diversity. Each parent receives 1.5 hours of intervention per week for 10 weeks by a masters or doctoral level clinician. The first three sessions focus on understanding feeding problems and behavior management strategies in children with ASD.The next seven sessions include child-specific feeding interventions, based on parent-report and home data collection of child meal time behavior. To promote application of new skills, homework accompanies each lesson. The next seven sessions include child-specific feeding interventions, based on parent-report and home data collection of child meal time behavior. To promote application of new skills, homework accompanies each lesson.<br>|
| Active Comparator: Parent Education<br>Parents of eligible children who are randomized to the Parent Education Arm will receive group-based parent education (PE). Each group includes 4 parents. | Behavioral: Parent Education<br>* The Parent Education study arm includes 10 sessions focusing on the following topics: understanding Autism Spectrum Disorder (ASD), clinical assessments for ASD, development in children with ASD, medical and genetic comorbidities in ASD, family and sibling issues, treatment alternatives, and education and treatment planning. The Parent Education arm does not include topics related to feeding problems or feeding specific interventions. Each parent receives 1.5 hours of intervention per week for 10 weeks by a masters or doctoral level clinician. Children randomized to Parent Education will be offered the Autism MEAL Plan after completing the 10-week randomized trial.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Clinical Global Impression - Improvement scale (CGI-I) score | The Clinical Global Impression - Improvement scale (CGI-I) is a 7-point scale measure of overall change of Parent Target Problems (the child's two most pressing problems at screening, as reported by parents), using scores from the Clinical Global Impressions - Severity scale (CGI-S). Scores range from 1 (Very Much Improved) through 4 (Unchanged) to 7 (Very Much Worse). | Baseline, end of follow-up (up to 18 weeks) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Parenting Stress Index- Short Form (PSI) score | The Parenting Stress Index- Short Form (PSI) is a 36-item survey commonly used | Baseline, end of follow-up (up to 18 weeks) | 
| Parent Satisfaction Rating | A 10 item Parent Satisfaction Rating questionnaire will assess acceptance and perceived effectiveness of each treatment arm. | Week 14 | 
| Change in Brief Autism Mealtime Behavior Inventory (BAMBI) scores | The Brief Autism Mealtime Behavior Inventory (BAMBI) is an 18-item parent-rated questionnaire on mealtime behaviors | Baseline, end of follow-up (up to 18 weeks) | 
| Change in Food Preference Inventory (FPI) scores | A 154-item parent-rating of food selectivity. It includes seven food categories (fruits, vegetables, proteins, starches, dairy, miscellaneous/snack, combination foods. The food selectivity score = the number of foods reported as never consumed divided by 154 X 100. We will also derive a food acceptance score = the number of food items endorsed as accepted divided by 154 X 100. | Baseline, end of follow-up (up to 18 weeks) | 
| Change in nutritional intake | Nutritional intake will be assessed by parents recording the child's daily intake on a food diary for 3 days prior to the Baseline, Week 10, Week 14, and Week 18 visits. A nutritionist (blind to treatment assignment) will tally the child's intake of selected vitamins and nutrients (vitamins A, C, D, and E, zinc, calcium, iron, fiber, fat, protein, carbohydrates, and total energy [kcal]) to determine the overall level of each micro- and macro-nutrient. The total number of nutrient deficiencies will be determined using cut points. The evaluation of change in nutritional status will be assessed by averaging the levels of each nutrient across groups. | Baseline, end of follow-up (up to 18 weeks) | 
| Change in Aberrant Behavior Checklist (ABC) scores | The Aberrant Behavior Checklist (ABC) is a commonly used 58-item parent-rated measure of overall behavioral problems. Subscale categories of the ABC include: Irritability, Lethargy, Stereotypy, Hyperactivity, and Inappropriate Speech. | Baseline, end of follow-up (up to 18 weeks) | 
| Change in rapid acceptance during 10 minute meal observation | Children and parents will participate in a 10-minute meal observation at the Baseline, Week 10, Week 14 and Week 18 visits. During the 10-minute meal observation caregivers are instructed to present a small bite of food to the child at 30-second intervals with a preset group of foods (e.g., green beans, peaches, grilled chicken, potatoes). Data are collected on a variety of mealtime behaviors including rapid acceptance of food presented. Outcomes are rated by trained observers using conventions established in the Marcus Autism Center's Feeding Disorders Program. | Baseline, end of follow-up (up to 18 weeks) | 
| Change in rapid swallowing during 10-minute meal observation | Children and parents will participate in a 10-minute meal observation at the Baseline, Week 10, Week 14 and Week 18 visits.

Data are collected on a variety of mealtime behaviors including rapid swallowing of food presented. Outcomes are rated by trained observers using conventions established in the Marcus Autism Center's Feeding Disorders Program. | Baseline, end of follow-up (up to 18 weeks) | 
| Change in disruptions during 10-minute meal observation | Children and parents will participate in a 10-minute meal observation at the Baseline, Week 10, Week 14 and Week 18 visits. During the 10-minute meal observation caregivers are instructed to present a small bite of food to the child at 30-second intervals with a preset group of foods (e.g., green beans, peaches, grilled chicken, potatoes). Data are collected on a variety of mealtime behaviors including disruptions (e.g. head turning, pushing away the spoon) when food is presented.
