Study Phases:

Phase 1: Assessment. A clinical interview will be undertaken via videoconferencing to ascertain the safety and suitability of the programme for each participant, and to gather information about the child’s developmental history; family context; eating/feeding problems; and demographic information. This interview will last between 30-45 minutes in duration and will be undertaken by a registered psychologist or post-graduate student who is a member of the research team, under the supervision of the lead investigator.

Phase 2: Baseline. Parents will be randomly assigned to a baseline length of 5, 10, or 15 days. Parent-reported diary data will be collected on the type and quantity of foods consumed and the frequency, severity, and duration of each any challenging behaviour associated with eating/feeding across this baseline period.

Phase 3: Intervention. Intervention will consist of two sequential sub-phases. Progression through each sub-phase will depend on whether the identified problem has resolved and/or parents’ satisfaction with progress.

Intervention sub-phase 1 - parent psychoeducation and online learning modules. Parents will independently engage with web-based, multi-media content, activities, and resources, embedded within a series of modules. Module content will be developed based on existing empirical research and the extensive research and clinical expertise of the named investigators, and empirically-supported interventions for feeding difficulties. Collectively, these modules will form an online parent Toolkit relating to each health-promoting behaviour. It is estimated that it will take parents 1-2 hours to work through each module and they will engage with these modules at their own discretion. This phase will last for four weeks.

For parents in the feeding study, Module 1 will focus on identification and assessment of feeding problems, and goal setting. Module 2 will focus on the role of nutrition and appetite and its overall impact on feeding difficulties (e.g., mealtime routine, meal schedule, and meal duration). Strategies to assist in the mealtime routine will also be introduced. Module 3 will help parents to identify the events that occur before or during mealtime that affect your children’s eating and strategies that can be implemented ahead of time that might make the mealtime more positive and help children to become competent eaters. Module 4 will focus on the identification of consequences that affect children’s eating, such as rewards for positive behaviour and will include strategies that can be used in response to children eating or not eating. Module 5 will help parents to summarize the information they learned and come up with a plan to help improve children’s feeding.

Intervention sub-phase 2 - synchronous videoconferencing in small groups (n = 3-5 families/group) with weekly feedback from a specialist. This phase will commence immediately after intervention sub-phase 1. During this phase, parents will partake in small group, weekly, 2-hour video conferencing sessions where they will have the opportunity to pose questions and discuss treatment plans with a specialist (e.g., named investigator or psychologist). The specialist will use assessment information to support parents to select empirically supported interventions and progress will be reviewed weekly within group training sessions. This phase will last for 4 weeks.

Intervention sub-phase 3 – synchronous, individualized, parent coaching sessions. Parent coaching will be provided for individual parents during the mealtime routine. This live coaching will be provided weekly, for up to one hour, by a specialist who is a member of the research team, for a period of four weeks. Parents will be supported to implement interventions during this time. This phase will commence immediately following completion of intervention sub-phase 2.

Phase 4: Follow-up. Data will be collected for one week, at 12 weeks and 6 months post-intervention, to assess the maintenance of intervention effects.

Parents will be asked to record the strategies that they implemented during intervention within the data sheets. Website analytics will be used to assess the frequency and duration of engagement with web-based materials. Attendance at weekly group coaching sessions and individualized coaching will be recorded by the research team.

It should be noted that participants can choose to withdraw from intervention at any time. If they are satisfied with their child’s progress and do not wish to proceed to intervention sub-phase 2 or 3 then they do not have to do so. If a parent would like to remain in intervention sub-phase 1 for more than four weeks they will not be able to progress to intervention sub-phase 2, as this is a group coaching phase and relies upon a cohort progressing collectively. If this is the case, parents can continue to have independent site access but will be considered to have withdrawn from the study. There is no ‘readiness’ criteria for progressing through intervention phases that is stipulated by the research team as the levels of support increase across each phase. On conclusion of the 12-week intervention period (the maximum duration of involvement in the study), parents can continue to have independent access to the website, if they choose to do so though they will not be required to collect data beyond the 12 weeks.

Participants will include a minimum of 15 parent-child dyads who meet the following inclusion criteria: (1) a formal diagnosis of Autism Spectrum Disorder (ASD) or features of ASD (i.e., awaiting diagnosis); (2) between 2 and 5 years of age; (3) parent-reported eating/feeding problems; (4) absence of a physical/medical condition affecting that may make implementation of a behavioural intervention unsafe and are not being effectively managed; and (5) not currently receiving services in the target domain.
Minimum age
2 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Children will be excluded from the study if they are currently under the care of a paediatrician or dietician with respect to eating/feeding as these children are likely to have nutritional concerns or feeding difficulties that require a more comprehensive intervention (e.g., presence of a feeding tube, prescription for specialised formula). If in doubt, we will consult with the specialist providing this medical care, to determine the safety and suitability of the programme.

Efficacy
Statistical methods / analysis
A minimum sample size of n=15 child-parent dyads will ensure sufficient replications to support causal inferences about treatment effects and will permit group statistical as well as individual analysis.

Data will be reported from all cases following the intention-to-treat principle, with description of means, medians, and ranges for each phase. Time-series diary data will be graphed using standard multiple-baseline graphs and examined for changes in level, trend, and variability across phases and participants and for any pattern of therapeutic change coincident with therapy phases. Magnitude of therapy effect will be assessed by the Percent Deviating from the Median (PDM) Effect Size (ES). DVs for which there is one or a few data points per case per phase (e.g., VABS-III; DASS) will be analysed by Modified Brinley Plots, Cohen’s d (standardised mean difference) ES with 95%Confidence Intervals and the Common Language ES (CLES). Website analytics data (e.g., engagement) will be used to examine any moderation effects on treatment outcomes.

Summary
Brief summary
About 40-80% of children with autism experience difficulty developing healthy eating/feeding habits. Without effective treatment, these difficulties are unlikely to abate, contributing significantly to the life-time personal, social, and economic cost of autism.

In Aotearoa, intervention and support for children on the autism spectrum and their families is typically delivered in an individualised/face-to-face format. Moreover, evidence-based behavioural interventions, although often effective, require a significant investment of time, funding, and resources on the part of parents and service providers, in many cases, precluding access to services for those in remote or underserved communities.

Internationally, telehealth technologies (i.e., videoconferencing, telemonitoring, and smartphone apps) have been used to deliver a variety of evidence-based interventions to children with autism and their families, however, there is a scarcity of research investigating the effectiveness of telehealth-delivered interventions for a key number of critical health-promoting behaviours (specifically eating/feeding difficulties) in children on the autism spectrum. Furthermore, there appear to be no studies focused on the prevention of problems in these areas, using either conventional or telehealth methods. Telehealth-delivered interventions might be particularly well-suited to addressing these types of health-related difficulties because the presenting problems frequently occur outside of conventional clinical hours and there is a shortage of trained professionals to address such problems. Consequently, difficulties in these areas must often be managed by parents at home, 24 hours per day, with little or no support or guidance, leading to stress and reduced quality of life.

The aims of this research are to (1) investigate the efficacy of telehealth-delivered behavioural interventions for eating/feeding problems in children on the autism spectrum; (2) identify the essential components of effective telehealth interventions for addressing these health-promoting behaviours; (3) identify whether the telehealth approach is perceived by parents to be culturally responsive, acceptable, and beneficial; and (4) assess the collateral benefit of improvement in health-promoting behaviours on a child’s daytime behaviour, adaptive functioning, quality of life, and parental well-being.

We hypothesise that (1) telehealth-delivered behavioural interventions will reduce the severity of children’s’ eating/feeding problems; (2) any reduction in the severity of problems will be maintained at follow up; (3) parents will use the telehealth technologies effectively and with fidelity and they will be viewed positively by parents; and (4) as target problems improve there will be collateral improvements in the children’s adaptive behaviour and quality of life and parent wellbeing.
