What this trial studies

This is a randomized, assessor-blind, parallel-group trial comparing group-based CBT-I with a health-related psychoeducation control in youths with DSM-5 insomnia disorder. Participants meeting inclusion criteria will be randomly assigned using an automated online system and will complete assessments at baseline, one week after the 7-week intervention, and at 6 months to measure maintenance effects. Outcomes include self-report and objective measures of impulsivity and risk-taking alongside insomnia severity and daytime functioning. The trial is conducted at the Sleep Research Clinic and Laboratory, Department of Psychology, The University of Hong Kong.

Who should consider this trial

Good fit: Chinese adolescents and young adults aged 12–24 with DSM-5 insomnia disorder and an Insomnia Severity Index (ISI) score ≥ 9, able to provide consent (with parental consent if under 18) and attend group sessions are ideal candidates.

Not a fit: Individuals with current substance abuse/dependence, a history of manic/hypomanic episodes, schizophrenia spectrum or neurodevelopmental disorders, significant medical conditions affecting sleep, or other diagnosed primary sleep disorders are excluded and unlikely to benefit from this trial.

Why it matters

Potential benefit: If successful, CBT-I could reduce impulsivity and risky behaviors in youths with insomnia, potentially lowering risks such as substance misuse and self-harm.

How similar studies have performed: Previous research has shown CBT-I can improve insomnia symptoms and daytime functioning in youths, but effects specifically on impulsivity and risk-taking are not yet well established.
