An app-based program to help children with ASD and insomnia sleep better

Effects of Digitally Delivered Parent-based Behavioural Sleep Intervention in Children With Autism Spectrum Disorder (ASD) - A Randomised Controlled Trial

Not applicable Interventional The University of Hong Kong · NCT07398183

This project will test whether an app-based, parent-led sleep program—with or without phone support—helps children aged 6–12 with ASD and insomnia and also improves parental sleep and stress.

What this trial studies

A randomized, assessor-blind parallel-group trial will compare three approaches: app-based cognitive behavioral therapy for insomnia (CBT-I) with personalized telephone support, app-based CBT-I without phone support, and treatment-as-usual. Parents of children with ASD aged 6–12 will use the app-delivered behavioral sleep program while researchers perform automated, gender-stratified randomization and blinded outcome assessments. Primary outcomes include child sleep measures (including sleep onset latency), plus clinical and daytime symptoms; secondary outcomes include parental sleep, mental health, and parenting stress, with assessments at baseline, one week post-intervention and additional 3- and 6-month follow-ups for active arms. The digital delivery aims to make the intervention scalable while personalized phone support tests whether added human contact improves outcomes.

Who should consider this trial

Good fit: Children aged 6–12 with a confirmed ASD diagnosis and chronic insomnia (sleep onset latency >25 minutes on ≥3 nights per week for ≥3 months) whose parents/caregivers can use an app and participate in follow-up are ideal.

Not a fit: Children without a confirmed ASD diagnosis, those outside the 6–12 age range, those whose insomnia is driven by untreated medical or medication issues, or families unable to engage with the app or phone support are unlikely to benefit.

Why it matters

Potential benefit: If successful, this could shorten children's time to fall asleep, improve daytime functioning, and reduce parents' sleep problems and stress.

How similar studies have performed: Prior trials of parent-based behavioral interventions and CBT-I have shown benefit for pediatric insomnia and some studies in ASD report improvements, but evidence for fully app-delivered programs with optional phone support is still emerging.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* (1) Parents/caregivers with a child aged 6 to 12 years old, and attending a local mainstream primary school at the time of recruitment;
* (2) The child is diagnosed to have ASD, which will be based on the assessment conducted by a psychiatrist or a clinical psychologist that incorporates the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) assessment criteria, with corroboration by the Autism Diagnostic Interview - Revised (ADI-R);
* (3) The child is reported by the parent/caregiver to have insomnia symptoms, typically a difficulty in falling asleep with or without bedtime resistance, which is operationally defined as sleep onset latency exceeding 25 minutes and occurring three or more times per week. The child's sleep problems have lasted for a minimum of three months and have led to an impairment in the daily functioning of the child and/or parents. Such inclusion criteria are based on the DSM-V criteria for insomnia, with the choice of a 25-minute sleep onset latency criteria based on the normative values reported by Scholle et al.;
* (4) Parent owns and knows how to use smartphones and can comprehend Chinese language;
* (5) The child's parent or guardian gives written informed consent of participation into the study;
* (6) Being able to comply with the study protocol.

Exclusion Criteria:

* (1) Children with diagnosed intellectual disability;
* (2) Children with any diagnosed co-morbid neurological or medical conditions which could have affected their sleep, such as blindness, traumatic brain injury, epilepsy and poorly controlled eczema;
* (3) Children with diagnosed sleep disorders other than insomnia or with suspected sleep apnoea (as assessed by the Children's Sleep Habits Questionnaire (CSHQ): obtaining a score of 4 or above on the sleep-disordered breathing subscale on the CSHQ) that may potentially contribute to a disruption in sleep continuity and quality. Children who are currently receiving regular melatonin treatment, as well as other medications such as Selective Serotonin Reuptake Inhibitors (SSRIs), will be considered for inclusion in the trial if they continue to meet the eligibility criteria.
