Insomnia and hypertension are common health problems that often occur together and influence each other. This practical, low-cost, clinical trial will evaluate two behavioral treatments for insomnia (a brief intervention with therapist contact and a self-guided Internet intervention) compared to usual care. Participants will be recruited using the electronic health record in their primary care physicians' offices, and will be evaluated for sleep, blood pressure, and health outcomes after 9 weeks, 6 months, and 12 months.
