Summary of evidence review
No evidence was identified from studies in children aged under 5 years. NICE identified very limited evidence in children and adolescents (5–18 years of age) and no new studies were identified in the updated review. Please see other sections for details of studies that include organisation/school-based components in conjunction with other intervention approaches.
Organisation/School-based versus waitlist/usual care
No new evidence was found. NICE previously identified 8 RCTs comparing organisation/school-based interventions to waitlist/usual care ranging from very low to high quality. There were benefits in inattention symptoms by parent but not teacher report. There were no benefits in parent or teacher-rated ADHD total symptoms, hyperactivity symptoms, and broader functioning/behaviour. There was limited evidence of improvements in terms of academic literacy/numeracy or academic performance outcomes.
Organisation/School-based versus Non-specific supportive therapy
No new evidence was found. NICE previously identified one very low-quality RCT (Molina et al., 2008). There was a clinically important benefit for adolescent-rated other symptoms but no clinically important benefit for emotional dysregulation.
