Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Individuals with prediabetes and insomnia will be randomized to receive six sessions of a deployment-ready digital CBT-I program, providing standard-of-care treatment for insomnia (intervention arm, n = 150), or a patient education website providing nontailored material about insomnia (control arm, n = 150). The investigators will complete assessments at baseline, at 11 weeks (after the conclusion of the intervention and control programs), and at 33 weeks post-baseline, measuring hyperglycemia, objective and subjective measures of sleep, and potential mediating variables including diet, exercise, and mood.
The investigators will assess (1) whether individuals randomized to the intervention arm have lower rates of hyperglycemia, as measured by oral glucose tolerance testing and various secondary measures, than individuals randomized to the control arm at 11 weeks and 33 weeks after baseline; (2) whether improvements in sleep after baseline are associated with decreases in hyperglycemia, regardless of study arm; and (3) whether any effects of the intervention on hyperglycemia are mediated by improvements in sleep, diet, exercise, and/or mood.
This research will serve as a critical step in identifying a potentially dramatic tool for improving health outcomes for Americans at risk of T2DM. Sleep interventions can lead to sustained improvements that are intrinsically rewarding to patients. If effective, digital CBT-I could provide a powerful pathway to preventing diabetes for millions of patients with prediabetes.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Digital cognitive behavioral therapy (dCBT-I)
CBT-I is designed to change sleep habits and scheduling factors that affect sleep, and to address misconceptions about sleep and insomnia that perpetuate sleep difficulties. The investigators will employ SHUTi, which is an extensively studied dCBT-I program. SHUTi is intended to improve insomnia symptoms by providing neurobehavioral intervention (cognitive behavioral therapy for insomnia - CBT-I) in adults with chronic insomnia. It is a six-core internet-delivered CBT-I web-based app that is run through a browser. It is accessible via iPhone/iPad, Android phone/tablet, computer or laptop (any device with a browser). SHUTi follows evidence-based CBT-I principles.
SHUTi
Each core includes a variety of interactive features, such as animations, vignettes, "myth" and "reality" buttons that reveal common misperceptions and facts about sleep, "learn more" buttons that provide in-depth information about a topic, and quizzes. All cores follow a similar structure with objectives, main content, homework, and review. Participants are free to revisit cores as many times as they like.
Patient Education (PE)
Participants will be given access to a patient education website. It will provide nontailored material about insomnia symptoms; the impact, prevalence, and causes of insomnia; and basic lifestyle, environmental, and behavioral strategies to improve sleep.
Patient Education
The PE website will present content in a simple, static form, without interactive components; and all content on the website will be provided at once, rather than in modules that unlock over time. The PE website will also not provide personalized or individually tailored treatment recommendations.
