Objective: To evaluate intervention characteristics and components within behavioral sleep interventions in school-aged children with ADHD and examine evidence related to effectiveness. Method: A systematic review was conducted using PsycINFO, Embase, MEDLINE, PubMed, and OpenGray. The subsequent meta-analysis used sleep outcomes to produce comparable effect sizes (Hedges' g) and compare intervention effects between randomized controlled trials and pre-post studies. Results: Eleven articles satisfied the inclusion criteria (562 children, across all groups, aged 5-14 years, M=8.71). Studies reported improvements in sleep although there was marked heterogeneity between studies and limited use of objective sleep measures within them. On average, intervention groups improved more than control groups in the five randomized controlled trials (-0.46, 95% CI=[-0.58, -0.35], k=4). Conclusion: The findings support the use of behavioral sleep interventions for school-aged children with ADHD. Findings suggest that brief, individualized intervention may be more effective than standardized.
