Brief summary
Parents as primary caregivers play an important role in shaping children's mealtime and eating behaviors; and in preventing weight gain. Conventionally, in-person, parent-implemented treatments have worked well for children with autism, however, post-COVID-19 pandemic there is a need for virtual, evidence-based training for parents to improve nutrition in children with autism and weight issues. This study aims to: a) increase self-efficacy among parents of children with autism and overweight or obesity to feed their children a healthy diet, b) improve parental nutrition knowledge and skills on how to feed their child with autism and overweight or obesity a healthier diet, c) improve their child's mealtime behaviors, and d) increase the child's dietary variety.
Detailed description
This study sought to recruit 24 parents of children with Autism Spectrum Disorder (ASD), and overweight or obesity via emails, digital flyers, and handouts on social media (Facebook), in the USA. This randomized, controlled trial behavioral intervention was conducted from September 2023 to February 2024 and included a YouTube-delivered, 8-week, virtual, nutrition education intervention for the parents. Participants were randomly allotted to either the intervention or control group by using the randomization (RAND) function on Microsoft Excel. Participants in the intervention group received access to the 16 YouTube videos, educational handbook, recipe modeling, and other training, while participants in the control group only got access to the questionnaires/surveys. All 8 video modules focused on increasing parental nutrition knowledge, skills, and perceived confidence in making food and nutrition-related decisions to feed their child and address mealtime problems, which aligns with Bandura's Social Cognitive Theory constructs of self-efficacy and behavioral capabilities. Participants were asked to complete validated questionnaires at baseline, mid-point, and end: parental self-efficacy; the Nutrition knowledge survey; Brief Autism Mealtime Behavior Inventory (BAMBI), followed by a small qualitative open-ended questionnaire for parental feedback on the overall acceptability and satisfaction of the intervention at the end of 8-weeks. All participants were asked to use the ASA-24 (National Cancer Institute) to complete a 24-hour food recall for their child with autism at baseline and end-point. Demographic data was collected at baseline for all participants. Participants were selected if a) they were 18 years or older; b)had a child with autism between the ages 6 and 11 years c) child's Body Mass Index was \> 85th percentile; d) child accepted at least 20 foods e) child did not take any medicines that affect appetite and weight.
Interventions
BEHAVIORALYouTube nutrition education
For those in the intervention group, the YouTube training modules had step-by-step recipe demonstrations, strategies on how to get your child to eat more new foods, social stories, First-Then visual chart, and other nutrition education materials. All the videos were less than 5 minutes long, and parents were assigned 2 videos per week for 8 consecutive weeks. Parents answered 2 open-ended questions each week related to the educational materials they reviewed.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Parental self-efficacy | 8 weeks | The study utilized a previously validated 9-item list questionnaire that measured their level of confidence (self-efficacy) in their ability to make nutrition-related decisions for their child with autism and overweight or obesity |
| Parents's nutrition knowledge | 8 weeks | To test this, a previously validated 18-item questionnaire was administered to test their knowledge of family mealtimes, food groups, and meal planning. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Brief Autism Mealtime Behavior Inventory (BAMBI) | 8 weeks | This is an 18-item questionnaire designed to evaluate mealtime behaviors in your child with autism. |
| Child's food intake | 8 weeks | The Automated Self-Administered 24-hour (ASA24®) dietary assessment tool was used to collect and analyze the child's dietary intake to monitor any changes pre and post-intervention. |
