What this Trial Is About
This research investigates the effects of Cognitive Behavioural Therapy for Insomnia (CBT-I) on impulsivity and risk-taking behaviors in youths aged 12 to 24 with insomnia. The study responds to evidence linking insomnia with impaired inhibitory control and adverse outcomes such as substance abuse and self-harm. It aims to evaluate whether CBT-I can improve impulsivity compared to a psychoeducation control in this population. Participants will be randomly assigned to receive either group-based CBT-I or a health-related psychoeducation control. The CBT-I involves six weekly 90-minute group sessions focusing on sleep hygiene, stimulus control, sleep restriction, relaxation, cognitive restructuring, and relapse prevention. The control group will also attend six weekly sessions covering general well-being, diet, and exercise information. Assessments occur before treatment, one week after the last session, and six months post-treatment to examine lasting effects. During the trial, researchers will measure changes in impulsivity using self-reports and objective tests, alongside sleep diary and actigraphy data. Cognitive performance tasks and ERP components related to impulsivity and risk-taking will also be evaluated at each time point. The study includes safety monitoring and requires participant compliance with the protocol over approximately seven weeks plus follow-up at six months.
