Pilot Testing of a Mobile Phone App-based Intervention for Parents of Children With Autism Spectrum Disorder (ASD)

The objective of this study is to conduct a pilot randomised controlled trial (RCT) evaluating the feasibility, acceptability, and preliminary efficacy of a 6-week mobile app-based intervention in empowering and supporting Chinese parents of autism spectrum disorder (ASD) children through knowledge and skills transfer and mindfulness training. The investigators hypothesise that the app will be feasible and acceptable, and that there will be a greater reduction in parental stress and mood symptoms, and improvement of mindfulness attitude and parenting competence in parents with ASD children after the 6-week app-based intervention than the waitlist controls.

Parents of autism spectrum disorder (ASD) children are often stressed about challenges in raising their children with multifaceted needs, and their stress could undermine the child's development. With the ever-increasing demand in clinical services and disruptions by the coronavirus pandemic (COVID-19), the aim of the study is to investigate the clinical efficacy of a mobile app-based intervention in reducing stress and mood symptoms, and enhancing mindfulness and competence in parents of children with ASD. The 6-week mobile app-based intervention programme, TRIP, is a structured course of mindfulness training, and knowledge and skills transfer of parenting ASD children with specific content personalised to the participant's needs, which was developed as an accessible and scalable primary-level care platform to improve the well-being of parents.

In this study, a pilot randomized waitlist-controlled trial will be conducted. 40 parents of ASD children who are ≤12 years of age and either 1. waiting for, or 2. actively receiving treatment from a regional children psychiatric specialist clinic will be recruited. Parents will be randomized into an immediate intervention arm and a waitlist arm. Feasibility, acceptability, as well as preliminary efficacy of the app will be investigated. Parental stress level, mood symptoms, competence, and level of mindfulness will be measured before, immediately after, and 2 months after the intervention with self-reported questionnaires.

The results of the proposed study will provide insights with regards to the design and implementation of the main randomised controlled trial (RCT), contributing to the generation of evidence to the real-life efficacy of a mobile app-based intervention service model to support parents of children with ASD in the era of digital mental health. As the impact of mental well-being of parents extends beyond the parents themselves, effective management of the elevated level of parental stress in ASD families is beneficial to the family functioning and long-term development of the child. The solid evidence from the main trial can also inform clinicians and service-users in choosing the evidence-based intervention suitable to their context, among the range of commercially available products with claimed efficacy.
