Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention includes 4 weekly meetings, 1.5 hours each. College students screened for insomnia attend group therapy based on standard cognitive behavioral therapy for insomnia protocol. Participants complete weekly sleep diaries throughout the intervention. They are educated about sleep hygiene principles, stimulus control and sleep restriction therapies and are encouraged to alter their sleep practices based on these principles. Cognitive therapy for insomnia and relaxation therapies (e.g., mindfullness) are also introduced. Weekly follow up is conducted based on sleep diaries. Primary investigator (who completed official CBT and CBT- Insomnia training) together with doctoral student (registered nurse, supervised by the PI for CBT-Insomnia) will deliver the intervention.

Summary
Brief summary
The study aims to assess the efficacy of cognitive behavioral group therapy for insomnia (CBGT-I) on sleep (main outcome) and hyper-arousal (secondary outcome) in college students with insomnia. It is hypothesized that CBGT-I, administered for 4 successive weeks will improve sleep quality and reduce hyper-arousal.
