Sleep Healthy Using the Internet Mitigating Insomnia to Address Neurocognitive Difficulties (SHUTi MIND)
Study Details
Study Description
Brief Summary
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.

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). After the pre-assessment battery is 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 and two weeks of sleep diaries. After completing the post-assessment battery and sleep diaries, participants will have continued access to their assigned online program throughout the study duration. This same assessment (questionnaires + diaries) will be completed at 6, 12, 18, and 24 months.
Study Design
Arms and Interventions
| 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

Outcome Measures
Primary Outcome Measures
- Insomnia Severity Index [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Change in overall insomnia severity
Secondary Outcome Measures
- Wake after sleep onset (WASO) [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
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
- Sleep onset latency (SOL) [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Change in length of time that it takes to transition from wakefulness to sleep, measured in minutes, collected through sleep diary entries
- Multidimensional Fatigue Symptoms Inventory - Short Form [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
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) [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
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
- Match to Sample Visual Search [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Changes in attention and processing speed will be measured using the Cambridge Neuropsychological Test Automated Battery (CANTAB) Match to Sample Visual Search
- Spatial Working Memory Test [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Changes in working memory and executive function will be measured using the Cambridge Neuropsychological Test Automated Battery (CANTAB) Spatial Working Memory Test
- Paired Associates Learning [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Changes in episodic memory will be measured using the Cambridge Neuropsychological Test Automated Battery (CANTAB) Paired Associates Learning
- Sleep Efficiency [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Amount of time spent asleep divided by the total time in bed
Other Outcome Measures
- Insomnia Knowledge Scale [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Sleep knowledge and cognitive behavioral therapy for insomnia techniques; scores range from 0-10 and higher scores indicate greater insomnia knowledge
- Center for Epidemiologic Studies Depression Scale (CES-D) [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
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 [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Falls questionnaire including number and frequency of falls
- Patient-Reported Outcomes Measurement Information System (PROMIS) [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
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.
- Self-Efficacy Scale- Insomnia-Specific [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Global-, task-, and self-regulation self-efficacy changes are measured using Self-Efficacy Scale developed by Bouchard, Bastien & Morin (2010) and includes 40 questions. Questions are answered using a scale from 0 (can't do at all) to 100 (absolutely certain can do), where higher scores indicate higher self-efficacy.
- Lawson's Instrumental Activities of Daily Living Scale [Baseline, 9 weeks, 6 months, 12 months, 18 months, and 24 months]
Activities that allow an individual to live independently in a community. Score range from 0 (low function, dependent) to 8 (high function, independent).
