A Brief Parent-based Sleep Intervention for Children With Autism Spectrum Disorder

Not Applicable

Completed

• Conditions: Insomnia; ASD
• Interventions: Behavioral: Sleep hygiene practices and behavioural intervention

• Registration Number: NCT05010824
• Lead Sponsor: The University of Hong Kong

Brief Summary

Sleep problems are very common in children with ASD, with a prevalence rate as high as 78%, and often pose significant challenges and stress to the families. Sleep problems in children with ASD are strongly associated with the exacerbation of daytime symptoms, and poor parental sleep quality and mental health. The present study is a randomised controlled trial to compare the effects of a parent-based sleep intervention for children with ASD (aged 3-6). Eligible participants will be randomised to either intervention (three consultation sessions and four follow-up phone calls) or waiting-list control condition. Assessments will be conducted at pre-treatment (baseline), and one-week after the intervention (post-treatment).

Arm && Interventions

Group	Intervention	Description
Intervention group	Sleep hygiene practices and behavioural intervention	The intervention will involve three consultation sessions and four follow-up phone calls with parents to help them learn sleep hygiene practices and specific behavioural strategies to improve their child's sleep and follow up on the progress.

Primary Outcome Measures

Name	Time	Method
Child: change of insomnia symptoms (night waking)	Baseline, immediately after the treatment	Change of the child's night waking measured by the Children's Sleep Habits Questionnaire (CSHQ) night waking score (3 items; score range: 3-9)
Child: change of insomnia symptoms (bedtime resistance)	Baseline, immediately after the treatment	Change of the child's bedtime resistance measured by the Children's Sleep Habits Questionnaire (CSHQ) bedtime resistance score (6 items; score range: 6-18)
Child: change of insomnia symptoms (sleep onset delay)	Baseline, immediately after the treatment	Change of the child's sleep onset delay measured by the Children's Sleep Habits Questionnaire (CSHQ) sleep onset delay score (1 item; score range: 1-3)
Child: Change of child's sleep	Baseline, immediately after the treatment	Change of the child's sleep measured by the Children's Sleep Habits Questionnaire (CSHQ). The total score of CSHQ ranges from 33 to 99. A higher score reflects more sleep disturbance.

Secondary Outcome Measures

Name	Time	Method
Child: Change of child's executive functions reported by parents	Baseline, immediately after the treatment	Behavioral Rating Inventory of Executive Function - Preschool Version (BRIEF-P). It consists of 63 items that measure various behavioral manifestations of EF based on parent or teacher ratings, within the context of the child's everyday environment.
Parent: Change of parental stress	Baseline, immediately after the treatment	Chinese version of Parental Stress Scale (PSS). It contains 17 items representing pleasure or positive themes of parenthood (emotional benefits, self-enrichment, personal development) and negative components (demands on resources, opportunity costs and restrictions). Higher scores on the scale indicate greater stress.
Parent: Change of parental self-reported sleep quality	Baseline, immediately after the treatment	Pittsburgh Sleep Quality Index (PSQI), a validated 19-item measure used to assess sleep habits, quality, and quantity, producing a total score and seven sub-scores in sleep quality, sleep onset latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. The global score can range from 0 to 21. Higher scores suggest poorer sleep quality.
Parent: Change of parental mood symptoms	Baseline, immediately after the treatment	Depression Anxiety Stress Scales - 21 item (DASS-21) consists of three self-report scales designed to measure the emotional states of depression, anxiety and stress. Each of the three DASS-21 scales contains 7 items. Higher scores suggest more depression, anxiety and stress, respectively.
Parent: Change of parental insomnia symptoms	Baseline, immediately after the treatment	Insomnia Severity Index (ISI). Total score ranges from 0-28 and higher scores indicate greater insomnia severity.
Child: Change of child's behaviour & other clinical symptoms	Baseline, immediately after the treatment	Strengths and Difficulties Questionnaire - parent report, which is a 25-item screening measure for emotional and behavioral problems in children. It consists of five subscales. Each of the subscales consists of five items, and scale scores range from 0-10. A higher score is indicative of more problems for all subscales, except for the prosocial scale, where higher scores correspond to fewer difficulties in prosocial behaviour.
Parent: Change of parental sense of competence and satisfactory in parenting	Baseline, immediately after the treatment	Parental Sense of Competence Scale (PSOC), which is a scale designed to measures parental competence on two dimensions: Satisfaction and Efficacy. It is a 16-item Likert-scale questionnaire (on a 6-point scale ranging from strongly agree \[1\] to strongly disagree \[6\]), with nine questions under Satisfaction and seven under Efficacy.
Parent: Parent's satisfaction to the treatment	Baseline, immediately after the treatment	Treatment satisfaction rating scale, a parent-report measure specifically designed for the study. Lower scores suggest higher parental satisfaction.
Parent: Parent's overall health status	Baseline, immediately after the treatment	Short Form 12-item Health Survey (SF-12v2), a validated measure of health-related quality of life (HRQOL). It consists of 12 items that cover 8 subscales, namely physical functioning (PF), role physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role emotional (RE) and mental health (MH). The eight subscale scores can be aggregated into a physical component summary (PCS) score and a mental component summary (MCS) score. Each of the eight SF-12v2 subscale has a scoring range from 0 to 100; a higher score indicates better HRQOL.
