Sleep Healthy Using the Internet Mitigating Insomnia to Address Neurocognitive Difficulties (SHUTi MIND)

Internet-based Insomnia Intervention to Prevent Cognitive Decline in Older Adults With Mild Cognitive Impairment (SHUTi MIND)

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.

• Status: Recruiting
• Conditions: Nervous System Diseases; Sleep Disorders, Intrinsic; Dyssomnias; Sleep Wake Disorders; Insomnia; Sleep Initiation and Maintenance Disorders; Cognitive Dysfunction; Alzheimer Disease; Mild Cognitive Impairment
• Intervention / Treatment: Behavioral: SHUTi OASIS; Other: Patient Education

Detailed Description

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 patient education (PE) control condition on sleep and cognition. Internet-based recruitment methods will be used, and outcomes include sleep variables (reduced overall insomnia severity and wake after sleep onset), daytime variables (reduced levels of fatigue, improved quality of life, and improved mood), and cognitive status (memory, attention/psychomotor speed, and executive functioning domains). Participants will complete a pre-assessment battery, which consists of an online cognitive test, an online questionnaire, and two weeks of sleep diaries. Once complete, participants will be randomized to either the Internet-based PE or CBT-I intervention. At the start of week nine, all participants will be instructed to complete the post-assessment battery (cognitive test, questionnaires, and diaries). After completing the post-assessment, participants will have continued access to their assigned online program throughout the study duration. This same assessment (cognitive test, questionnaires, and diaries) will be completed at 6, 12, 18, and 24 months.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: SHUTi OASIS; Participants will be assigned to the SHUTi (Sleep Healthy Using the Internet) for Older Adult Sufferers of Insomnia and Sleeplessness (OASIS) online intervention optimized for older adults. CBTi will be delivered online and metered out over time with each new core becoming available one week after the completion of the previous core. The intervention period is 9 weeks. They will spend 1-2 hours during the intervention period 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 on how to improve their sleep.	Behavioral: SHUTi OASIS; Cognitive Behavioral Therapy for insomnia delivered online and metered out over 6-9 weeks in a fully automated, interactive, tailored web-based program
Placebo Comparator: Patient Education Website; 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.	Other: Patient Education; An educational website containing information on insomnia

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Insomnia Severity Index	Change in overall insomnia severity	Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Wake after sleep onset (WASO)	Change in periods of wakefulness occurring after defined sleep onset as measured by daily sleep diaries over 10-14 day periods, measured in minutes, collected through sleep diary entries	Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months
Sleep onset latency (SOL)	Change in length of time that it takes to transition from wakefulness to sleep, measured in minutes, collected through sleep diary entries	Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months
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	Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months
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	Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Insomnia Knowledge Scale	Sleep knowledge and cognitive behavioral therapy for insomnia techniques; scores range from 0-10 and higher scores indicate greater insomnia knowledge	Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months
