Brief summary
The aims of this study is to determine if improving sleep quality could improve executive functions in medical students by comparing cognitive behavioral therapy for insomnia (CBT-I) with sleep hygiene education (SHE) in a randomised controlled trial (RCT). The primary hypotheses for the trial are that, compared to sleep hygiene education (SHE): 1. The ICBT intervention will be associated with improved sleep quality (SQ) after 1-month, 3-months and 6-months end of treatment. 2. The ICBT intervention will improve executive functioning (EF) after 1-month, 3-months and 6-months end of treatment. 3. The ICBT intervention will be associated with improve to total sleep time (TST), sleep onset latency (SOL), number of awakenings (NOA), wake time after sleep onset (WASO), and sleep efficiency (SE) after 1-month, 3-months and 6-months end of treatment. 4. The dysfunctional beliefs and attitudes about sleep, pre-sleep worry, and sleep hygiene will be significantly mediators the treatment effects of CBT-I on sleep quality (SQ) and sleep efficiency (SE).
Interventions
The Cognitive Behavioural Therapy for Insomnia (CBT-I) involves 6 weekly online group interaction sessions with a CBT-I trained clinical psychologist. Each session will consist of 28 participants.
Each session will last 45 to 60 minutes.
Session 1 will involve psychoeducation about sleep regulation.
Session 2 will involve sleep restriction.
Session 3 will involve sleep hygiene and stimulus control.
Session 4 will involve Progressive Muscle Relaxation (PMR) based on Jacobson.

Each session will last 45 to 60 minutes. Session 1 will involve psychoeducation about sleep regulation. Session 2 will involve sleep restriction. Session 3 will involve sleep hygiene and stimulus control. Session 4 will involve Progressive Muscle Relaxation (PMR) based on Jacobson. Session 5 will involve cognitive restructuring. Session 6 will involve relapse prevention. All treatments adherence in the CBT-I will be monitor by online attendance on the paid zoom platform and all participants will be required to switch on their web camera. Short online quizzes will also be periodically provided on each session to ensure all participants are active and understanding the content of the session objective,
