Experimental
Blended e-health intervention
i-Sleep & BioClock Intervention
The 'i-Sleep \& BioClock' intervention aims at improving sleep and the biological clock among university students. It is incorporates evidence-based techniques such as cognitive behavioural therapy for insomnia (CBTi). The intervention has a duration of 5 weeks and consists of five modules:
1. psychoeducation on insomnia, sleep hygiene and the biological clock,
2. stimulus control and sleep restriction therapy,
3. worrying and relaxation exercises,
4. cognitive therapy to change dysfunctional thoughts about sleep, and
5. summary module, relapse prevention, and plan for the future.
The intervention is supported by e-coaches who give personalized written feedback. Students will fill in a sleep \& light exposure diary daily.
