Guest Commentary by Dr. Margaret Weiss: A two-session intervention is effective in improving sleep hygiene.
BACKGROUND: We aim to (1) determine whether a behavioural sleep intervention for children with attention-deficit/hyperactivity disorder (ADHD) leads to sustained benefits; and (2) examine the factors associated with treatment response.
METHODS: This study was a randomized controlled trial of 244 children (5-13 years) with ADHD from Victoria, Australia. All participants had a moderate/severe sleep problem that met American Academy of Sleep Medicine criteria for an eligible sleep disorder by parent report. The two-session intervention covered sleep hygiene and standardized behavioural strategies. The control group received usual care. Parent- and teacher-reported outcomes at 12 months included sleep, ADHD severity, quality of life, daily functioning, behaviour, and parent mental health. Adjusted mixed effects regression analyses examined 12-month outcomes. Interaction analyses were used to determine moderators of intervention outcomes over time. The trial was registered with ISRCTN, http://www.controlled-trials.com (ISRCTN68819261).
RESULTS: Intervention children were less likely to have a moderate/severe sleep problem by parent report at 12 months compared to usual care children (28.4% v. 46.5%, p = 0.03). Children in the intervention group fared better than the usual care group in terms of parent-reported ADHD symptoms (Cohen’s d: -0.3, p < 0.001), quality of life (d: 0.4, p < 0.001), daily functioning (d: -0.5, p < 0.001), and behaviour (d: -0.3, p = 0.005) 12 months later. The benefits of the intervention over time in terms of sleep were less for children not taking ADHD medication and children with parents experiencing depression.
CONCLUSIONS: A behavioural sleep intervention for ADHD is associated with small sustained improvements in child wellbeing. Children who are not taking ADHD medication or have parents with depression may require follow-up booster sleep sessions
