Sleep Healthy Using The Internet for Older Adult Sufferers of Insomnia and Sleeplessness (SHUTiOASIS)

This study will compare the efficacy of an interactive internet intervention for older adults with insomnia called SHUTi OASIS (Sleep Healthy Using the Internet for Older Adult Sufferers of Insomnia and Sleeplessness) accessed at www.shutioasis.org both with and without support for adherence to that of a static educational website to improve sleep, health, mood, and overall quality of life.

Insomnia is a significant public health problem for older adults with substantial medical, psychological and financial ramifications. With as many as 20-30% of older adults (age ≥55) meeting diagnostic criteria for chronic insomnia, finding accessible, effective, and low-cost treatments is critical. Cognitive-Behavioral Therapy for Insomnia (CBT-I) is a non-pharmacological intervention that has been shown to be efficacious when tailored for older adults. Regrettably, access to this treatment is significantly limited by a lack of trained clinicians and expense. To overcome barriers to face-to-face care, use of the Internet has emerged as a feasible and effective method to provide health information and treatment. Unfortunately, the health care field has been reluctant to use technology-delivered solutions with older patients out of a concern that older adults either do not have access to or do not want to use technology. However, older adults in the U.S. are the largest growing group of Internet users, and they generally have a desire to learn new technologies. When older adults do use technology-based programs for health promotion, they rate these programs favorably. Internet-delivered CBT-I for older adults has a high likelihood of major public health impact by allowing widespread access to a needed intervention, increasing the convenience of obtaining care, and decreasing treatment costs among an age group with high rates of insomnia known to exacerbate other concerns (health, mood, cognition). The SHUTi Program: SHUTi is a self-guided (i.e., automated), interactive, and tailored web-based program modeled on the primary tenants of face-to-face CBT-I (sleep restriction, stimulus control, cognitive restructuring, sleep hygiene, relapse prevention). Intervention content is metered out over time through 6 "Cores." Users obtain access to a new Core based on a time and event-based schedule (e.g., 7 days after completion of previous Core). This schedule is consistent with the recommendation from a task force commissioned by the Academy of Sleep Medicine, which deemed that an average of 6 - 8 sessions constitutes "adequate treatment exposure". The SHUTi program relies on user-entered online Sleep Diaries to track progress and to tailor treatment recommendations (i.e., assign a "sleep restriction" window). Each Core acts as an online analog for the weekly sessions typically used when delivering CBT-I in a face-to-face format, following the same general structure: 1) Core objectives (what will be learned and why this information is important), 2) review of previous week's homework and sleep diary data, 3) new intervention material, 4) assignment of homework (treatment strategies for the coming week), and 5) a summary of the Core's main points. Intervention content is enhanced through a variety of interactive features, including personalized goal-setting, graphical feedback based on inputted symptoms, animations / illustrations to enhance comprehension, quizzes to test user knowledge, patient vignettes, and video-based expert explanation. Automated emails are also sent to encourage program adherence. Participants in this study will be randomly assigned for a period of 9 weeks to one of three conditions: (1) the online CBT-i intervention optimized for older adults (SHUTi), (2) the online CBT-i intervention optimized for older adults (SHUTi) with additional adherence and technical support provided (stepped care), or (3) the patient education website. All participants will complete questionnaires and two weeks of daily sleep diaries about their symptoms at four time points - at the beginning of the study (baseline), immediately after completing the 9 week intervention (post), and at 6 and 12 months later.

Participants will be assigned to the SHUTi (Sleep Healthy Using the Internet) online intervention optimized for older adults. They will spend 1-2 hours each week for 6-9 weeks completing daily sleep diaries as well as interactive core content covering topics of sleep behaviors, sleep thoughts, sleep education, and relapse prevention targeting issues specific to older adults. As users progress through the intervention, they will receive automated, tailored instructions for how to improve their sleep.

Participants will be assigned to the SHUTi (Sleep Healthy Using the Internet) online intervention optimized for older adults. This is the same intervention as the first arm but with the addition of personalized emails or phone calls to participants by study personnel at specific time points as a result of not completing assigned tasks.

Participants will be assigned to a relevant patient education website. It will include information about insomnia symptoms, diagnosis, prognosis, and information about CBT strategies for the older adult. Unlike SHUTi, the content will not be tailored and will be presented all at once.
