Sleep Intervention in Children With ASD

Participants in this group will be instructed to download a smartphone application. The smartphone app-based intervention, involving six sequential modules, is structured and based on the well-established behavioural sleep intervention elements for managing sleep problems in children, with the consideration of catering to the needs of children with ASD. The main treatment components include: (1) psychoeducation about sleep in the developmental context as well as in the context of ASD, (2) sleep hygiene education, (3) sleep-focused behavioural strategies (e.g., consistent bedtime routine, bedtime fading, extinction, sleep restriction, use of 'bedtime pass'), (4) relaxation strategies, (5) cognitive restructuring (targeting dysfunctional cognitions) and (6) relapse prevention. A weekly phone call support by a trained therapist, using a semi-structured script, will be provided during the intervention period (around 15 mins each time) to the parents.

Participants in this group will be instructed to download the same smartphone application used in the app-based CBT-I with personalised support. No telephone support will be provided to this group.
