The iTAP Study for Veterans

Cognitive Behavioral Therapy for Insomnia (CBT-I). Participants assigned to the CBT-I condition will attend 1-hour individual sessions of CBT-I once a week for five weeks. A sixth week of treatment will be included - and scheduled for the same date as the post-treatment assessment - if the participant and research team agree that it would be beneficial (e.g., if a participant has difficulty grasping cognitive therapy concepts). Consistent with clinical guidelines (Schutte-Rodin, Broch, Buysse, Dorsey, \& Sateia, 2008), treatment will include stimulus control (e.g., limit use of bed to sleep or sexual activity, get out of bed if lying awake for more than 20 minutes), sleep restriction (limit time in bed to amount of time spent sleeping on a typical night), sleep hygiene (e.g., avoid exercise within 2 hours of bedtime, create cool and dark sleep environment), relaxation training, and cognitive restructuring.

All participants will receive a one-page handout on sleep hygiene that includes personalized normative feedback on their alcohol use. This is the only intervention that participants assigned to the Sleep Hygiene condition will receive and is consistent with what may be expected as standard care in a doctor's visit with a primary care physician.
