CBT-I group
Waitlist control group
Participants in the CBT-I condition start the 6-week CBT-I immediately after randomization, complete the post-intervention assessment right after they finish the treatment, and complete the follow-up assessment 4 weeks after the post-intervention assessment. They will be invited to participate in an interview after completing the post-intervention assessment.
Participants in the waitlist control group will wait for 6 weeks without the CBT-I intervention and then complete the post-intervention assessment; while waiting for 4 more weeks and then completing the follow-up assessment.
