Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is an adolescent adaptation of the Sleeping Sound Program, a behavioural sleep intervention, which has been evaluated with young children with ADHD and sleep problems (Hiscock et al., 2015; Sciberras et al., 2017). The program has been adapted to include modules that are relevant to the sleep problems experienced by adolescents with ADHD.

Intervention materials will include: (1) a sleep diary for adolescent participants to complete, (2) information handouts about normal sleep, sleep cycles and healthy sleep strategies and (3) further information (via handouts) regarding specific sleep difficulties that may be relevant to the adolescent participant (e.g., insomnia, delayed sleep phase). These handouts have been specifically designed for this study.

The program will include two 50-minute face-to-face sessions, held a fortnight apart and a follow-up phone call to both adolescents and their parents a fortnight later. The intervention will be provided individually to each family. The intervention will be delivered by study psychologists trained in the intervention by principal investigator and clinical psychologist Dr Emma Sciberras and supported by the investigator team. Face-to-face sessions will take place at Deakin University.

Intervention Procedures:

The first session will focus on an assessment of the adolescent’s sleep problem, providing information about normal sleep and sleep cycles, giving the adolescent a sleep diary to complete, advice about healthy sleep practices, and a plan specifically tailored to the adolescent’s sleep problem.

The second session will include a review of the sleep diary, re-enforcement/trouble shooting of existing strategies and the introduction of new strategies where appropriate. Adolescents and their parents will be called a fortnight later to again monitor progress and offer any final strategies.

Treatment fidelity will be maximised and assessed through: (1) fortnightly supervision meetings with clinicians led by principal investigator and clinical psychologist, Dr Emma Sciberras and (2) a standardised consultation record form to be kept by clinicians for each session including the presenting sleep diagnosis, medication use, comorbidities, and treatment progress.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomised after screening and baseline measures have been completed. Randomisation will be performed by a researcher independent of the project using a web-based randomisation schedule. Members of the research team do not have access to the randomisation schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation schedule will be pre- generated using block randomisation with variable block sizes by an independent research statistician, and loaded into the REDCap online platform. Randomisation will be stratified by gender to ensure similar proportions of males and females across groups. Eligible siblings will be randomised to the same group to avoid contamination.

Efficacy
Statistical methods / analysis
This trial is powered to detect a 0.53 SD improvement in adolescent-reported sleep problems. To achieve 80% power for a 0.53 SD difference at 3 months with a two-sided test with alpha =0.05 and anticipated 20% drop out, we will need to enrol 70 adolescents in each arm (140 total adolescents). This estimate also accounts for a clustering effect per recruitment site of .08 based on recruiting 4 participants per paediatrician practice.

All analyses will be conducted on an intention-to-treat basis. To account for loss to follow-up, analysis of the primary outcome (Adolescent Sleep Wake Scale) and all secondary outcomes will be carried out using mixed effects regression. For each outcome, a single mixed effects model will be fitted incorporating baseline and 3 month data using random effects to allow for the repeated measures within an individual. This approach implicitly deals with missing data as it enables all participants with baseline data to be included in the analysis.

Summary
Brief summary
ADHD is an impairing neurobiological disorder affecting over 300,000 young people in Australia. Up to 70% of children with ADHD experience sleep problems which contribute to substantially worse functioning. A number of studies have now demonstrated that sleep problems are amenable to intervention in young children with ADHD, with large improvements in sleep and child and family wellbeing.

This study will extend this program to adolescents with ADHD given that sleep problems continue to be prevalent in adolescents are associated with poorer wellbeing. We recently completed a small pilot randomised controlled trial (DUHREC 2018-135) of a sleep intervention for adolescents (N=11) which demonstrated that the intervention is feasible to deliver to adolescents and their parents. We will now conduct a novel RCT to efficacy of the adapted Sleeping Sound intervention in adolescents aged 13-16 years with ADHD.

It is hypothesised that compared to families in the usual care group, adolescents and parents in the intervention group will experience improved outcomes at 3 months post-randomisation for the following:

1. Adolescent sleep problems and sleep hygiene
2. ADHD symptom severity in adolescents
3. Adolescent wellbeing (i.e., mental health and quality of life)
4. Parent mental health
