Outcome Measures

Primary Outcomes (1)

  • Child: Change of child's sleep problems

    The Children's Sleep Habits Questionnaire (CSHQ) - parent report is a commonly used measure to assess sleep symptoms in children aged 4-12 years. It consists of 33 items to evaluate a child's sleep behavior over the past week. Items are rated on a 3-point scale to indicate the frequency of each sleep behavior: "usually/five to seven times per week," "sometimes/two to four times per week," and "rarely/zero to once per week." The CSHQ total score is the sum of the 33 questions and ranges from 33 to 99. Higher scores indicate more severe sleep disturbances.

    Baseline, Post-Treatment (1 week after intervention completion) for all participants, and additionally two follow-ups at Post-Treatment 3-month and Post-Treatment 6-month for participants in the treatment groups.

Secondary Outcomes (15)

  • Child: Change of child's ASD symptoms

    Baseline, Post-Treatment (1 week after intervention completion) for all participants, and additionally two follow-ups at Post-Treatment 3-month and Post-Treatment 6-month for participants in the treatment groups.

  • Child: Change of child's emotional and behavioural problems

    Baseline, Post-Treatment (1 week after intervention completion) for all participants, and additionally two follow-ups at Post-Treatment 3-month and Post-Treatment 6-month for participants in the treatment groups.

  • Child: Change of child's executive function

    Baseline, Post-Treatment (1 week after intervention completion) for all participants, and additionally two follow-ups at Post-Treatment 3-month and Post-Treatment 6-month for participants in the treatment groups.

  • Child: Change of child's daytime sleepiness

    Baseline, Post-Treatment (1 week after intervention completion) for all participants, and additionally two follow-ups at Post-Treatment 3-month and Post-Treatment 6-month for participants in the treatment groups.

  • Child: Change of child's quality of life

    Baseline, Post-Treatment (1 week after intervention completion) for all participants, and additionally two follow-ups at Post-Treatment 3-month and Post-Treatment 6-month for participants in the treatment groups.

TAU group

NO INTERVENTION

Participants will continue their usual clinical follow-up and receive standard treatment where needed. No app-based intervention and telephone support will be provided to this group.

Interventions

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.
