Parent-Mediated Intervention for Families With Children With Autism and Feeding Challenges, Australia Cohort

Autism Spectrum Disorder Clinical Trial

Official title: Parent-Mediated Intervention for Families With Children With Autism and Feeding Challenges, Australia Cohort

Status Recruiting

Clinical Trial Summary

The goal is to expand a parent-mediated intervention for feeding challenges in children with autism with an Australian cohort, building on recent research and current successful models already being used. A parent-mediated intervention would primarily occur in the home environment, working with the parent to establish goals and implement the intervention based on their child's specific needs.

Clinical Trial Description

Fifty families with a child with Autism spectrum disorder (ASD) will be asked to participate in 24 parent-mediated feeding intervention visits over approximately six-months. In addition, parents will be asked to participate in 6 to 8 parent training sessions in their home or by phone. Enrollment with two groups of families will be staggered to allow for any further adaptation and refinement of the protocol based on feedback from enrolled families. All families will be asked to participate in an initial intake session that will include an overview of the intervention program, assessment of the intervention targets, parent interview, observation/videotape of a family mealtime, and complete standardized questionnaires on specific variables (e.g., developmental level, autism severity and sensory processing) that can influence feeding behaviors to further describe the population and explore potential confounding variables. The assessments and mealtime observation will assist in determining the child's current feeding challenges and targeted goals. Both parent and child will be asked to participate in a video-taped mealtime and free play time during a laboratory session at pre and post-intervention time points. During the laboratory session, both parent and child will be asked to wear a heart rate activity monitor that attached to their chest via a harness and an electrodermal skin conductance wrist band to allow for wireless physiological data collection. In addition, parents and children will also be requested to wear the heart rate activity monitor two times in their home environment during family mealtime. Hair samples will be taken from both the parent and the child to assess recent stress levels. Parents will collaborate in Goal Attainment Scaling to allow for a pre- and post-test comparison of child specific goals. In addition, feeding assessments as well as a parent stress measure, heart rate variability, and hair cortisol measurement will be used for a pre- and post-test comparison. Parents will participate in brief structured interviews before, one time during, and immediately following completion of the program to provide feedback on the intervention. Intervention: 1. Parents will attend 8 group sessions that will be clustered in the first three quarters of the program focused on topics related to feeding challenges (e.g. goal setting, feeding development, parent-child interactions, sensory processing, behavior management, nutrition, the gastrointestinal system, and family mealtimes). Education sessions will be facilitated by the principal investigator and research team members. 2. Parents will receive 6-10 individual sessions with a feeding interventionist that will support targeted goal setting, problem solving and individual coaching and feedback through video review of parent-led intervention. 3. Parent-child dyads will receive 24 weekly sessions in the home that demonstrate modeling of intervention strategies and provide direct feedback of parent-led intervention. Parent satisfaction and burden will be assessed after each weekly session using a brief Likert scale questionnaire. 4. Parents will be asked to commit 10-15 hours per week in the home setting to directly support targeted feeding goals and related challenges such as sensory processing that may be a barrier to successful eating. Two trained individuals with experience working with children with ASD will be hired to support facilitation of the parent-mediated intervention. Several steps will be taken to train and supervise the interventionists. In addition, a minimum of 20% of their interactions will be video-taped reviewed by the principal investigator to monitor treatment fidelity. Analysis: Descriptive statistics will be used to describe the family and child characteristics as well as family satisfaction. Interview data from the parents will be audio recorded, transcribed verbatim and imported into Nvivo for data management and analysis support to inform future adaptations of the intervention program as well as beginning to unravel who the program may be most effective for and why. An analysis of variance (ANOVA) will be used to assess the pre- and post-intervention differences of the key variables of interest. ;
