Parent-mediated intervention delivered through telehealth for children with autism spectrum disorder

Parent coaching via telerehabilitation for young children with autism spectrum disorder (ASD): study protocol for a randomised controlled trial

BACKGROUND

Early parent-implemented intervention enhances parent-child interaction and improves language skills in children with autism spectrum disorders (ASD). Parent coaching is often delivered as standard care for children with ASD, where parents are taught to apply strategies in their child's play activities and daily routines to achieve the prior stated goals. However, the ability to conduct parent coaching in physical in-clinic sessions is limited by resource constraints such as clinic space and therapist manpower. Furthermore, parents may experience difficulties with the generalisation of intervention strategies taught in the clinic to their natural home environments. In this study, telerehabilitation is evaluated as an alternative platform to deliver parent coaching for parent-implemented interventions to children with ASD in their homes.

METHODS

This parallel-group, randomised, controlled, non-inferiority trial aims to evaluate the effectiveness of parent coaching delivered through video conferencing (telerehabilitation) versus in-clinic (standard care) delivery. Children aged 15 to 48 months (n = 200) who meet the cut-off score for ASD on the Autism Diagnostic Observation Schedule-2 are eligible. Parent-child dyads are randomly assigned to receive parent coaching either through weekly telerehabilitation or standard care. The primary outcome is the child's development as measured by the subscale and composite scores of a standardised developmental assessment. Primary analysis will determine if the lower boundary of the 95% confidence interval for the mean difference in pre-post change between groups exceeds -5 (the non-inferiority margin). Secondary outcomes are the child's adaptive behaviour, parent-child interaction, parental stress, and family quality of life. Outcomes will be measured pre-intervention, midterm, and post-intervention. Secondary analysis will determine if there is any between-group difference for the pre-post change in scores at the 5% significance level using two-sample t-test or Mann-Whitney U test.

DISCUSSION

As a randomised controlled trial of a moderately large scale, this study will contribute to the limited existing literature on the effectiveness of parent coaching via telerehabilitation for early parent-implemented intervention for children with ASD. The results of this study will provide insights on whether telerehabilitation is comparable to conventional in-clinic parent coaching in enhancing parent-child interaction and improving language skills.

Evaluation of Telehealth Delivery of Group Parent-Led Cognitive-Behavioral Therapy During COVID-19: A Pilot Study

The COVID-19 pandemic has led to governments around the world imposing varying levels of restrictions and lockdowns leading to home confinement and closure of schools. Children with autism spectrum disorder (ASD) and their families may be particularly susceptible to increased anxiety. A growing evidence base has developed for parent-led cognitive-behavioral therapy (CBT) for child anxiety disorders. The current pilot study aimed to evaluate the preliminary clinical utility (acceptability, feasibility, and efficacy) of a parent-led CBT program in Dublin, Ireland, through an online format. Parents of nine children completed the program. The child did not participate in any part of the online program. Acceptability was strong, and although technical issues were problematic at times, all families completed the program. Preliminary efficacy analysis is mixed, with significant reductions on youth anxiety as measured by clinician-administered questionnaire but no reduction in parent-report measures. Findings suggest that the online program is acceptance, feasible, and effective.
