This randomized controlled trial will evaluate the impact of an Internet-delivered cognitive behavioral therapy for insomnia (CBT-I) intervention on sleep and the extent to which it contributes to cognitive health in individuals with mild cognitive impairment. Participants with insomnia who meet the study criteria for mild cognitive impairment will be recruited to determine the effects of the CBT-I intervention compared to a patient education condition on sleep and cognition. Internet-based recruitment methods will be used, and outcomes include sleep variables, daytime variables, and cognitive status.

Multidimensional Fatigue Symptoms Inventory - Short Form
Change in self-report measures of five dimensions of fatigue ( general fatigue, physical fatigue, emotional fatigue, mental fatigue, and vigor) measured using Multidimensional Fatigue Symptoms Inventory-Short Form. Total MFSI-SF scores range from 24 to 96, with a higher score indicating a higher fatigue level
Short Form-12 Health Survey (Quality of Life)
The SF-12 Health Survey will be used to measure changes in physical and mental quality of life. Scores range from 0 to 100, with higher scores indicating better physical and mental health

Sleep knowledge and cognitive behavioral therapy for insomnia techniques; scores range from 0-10 and higher scores indicate greater insomnia knowledge

Depression and anxiety are measured using the Center for Epidemiologic Studies Depression Scale (CES-D). Scores range from 0-60, where higher scores indicate greater likelihood of depression
Falls frequency
Falls questionnaire including number and frequency of falls
Patient-Reported Outcomes Measurement Information System (PROMIS)
Pain intensity and interference are measured using PROMIS Pain Intensity questions. On a scale of 0-100, a score of 50 is considered the mean/reference population, and higher scores indicate greater pain intensity.
