MBSI-I: Multicomponent Behavioral Sleep Intervention for Insomnia in Older Adults With Mild Cognitive Impairment
Study Details
Study Description
Brief Summary
Insomnia symptoms in older adults with mild cognitive impairment represent a significant public health burden in terms of impaired quality of life, risks from untreated insomnia, and risks from pharmaceutical insomnia treatment. To address the limitations in the most effective non-pharmacological treatments for insomnia in older adults with mild cognitive impairment, a randomized pilot study will be conducted to test a brief (4 week), tablet-based, personalized, multicomponent behavioral sleep intervention for insomnia, compared to a sleep education control, in this at-risk group. The findings of the proposed project will inform future, larger scale clinical trials and may provide a novel and innovative way for older adults with mild cognitive impairment to achieve better sleep and health-related quality of life outcomes.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Intervention Arm Meaningful activity protocol during the day and Assistive Relaxation Therapy (ART) at night; includes 1) Sleep Hygiene Education; 2) Meaningful Activity Modules a) Physical Activity b) Cognitive Activity and c) Social engagement; 3) ART, a breath-based relaxation intervention that is coupled with a physical anchoring task. Participants will complete a daily sleep diary, use the activity modules daily as pre-determined times personalized to the participant, use the ART software when they get in bed to help with insomnia symptoms, and wear an actiwatch for a four-week period. Participants will have biweekly phone consultation with the research nurse. |
Behavioral: Multicomponent Behavioral Sleep Intervention for Insomnia
The MBSI-I will include a meaningful activity protocol during the day and ART therapy at night.
|
| Active Comparator: Control Arm Study participants in the control group will also receive a tablet and watch, but the meaningful activity modules and ART software will not be accessible to them. The sleep hygiene educational material represents an active control intervention and is recommended as part of the initial treatment of insomnia based on an NIH guide for sleep education. This approach provides staff and technology interaction/attention that is comparable to the intervention arm, and thereby promotes adherence; it has been used as a placebo comparator for many insomnia treatment studies and has low attrition rates. Control subjects will also be asked to complete electronic sleep diaries and wear the actiwatch on the non-dominant wrist to monitor sleep/wake patterns. For both arms, participants will be asked to complete baseline assessments, 1 month (post-intervention) and follow-up (3 month). |

Outcome Measures
Primary Outcome Measures
- Sleep latency [immediately post-intervention]
time it takes a person to fall asleep, starting from first intention to sleep, measured by sleep diary
- Sleep latency [3 months post intervention]
time it takes a person to fall asleep, starting from first intention to sleep; measured by sleep diary
- health related quality of life (HRQOL) [immediately post-intervention]
RAND Medical Outcomes Study Short Form-36 (SF-36) is a multidomain scale that measures physical and mental components of HRQOL with eight subscales. The 8 subscales contribute to two resulting component summaries: a mental component summary (MCS) and a physical component summary (PCS). Both PCS and MCS scores range from 0 to 100 (lower scores indicate worse HRQOL).

Secondary Outcome Measures
- Wake after sleep onset (WASO) [immediately post intervention]
time (in minutes) a person spends awake during the night, starting from the time the person falls asleep; derived from actigraphy monitoring; more WASO indicates worse sleep
- Wake after sleep onset (WASO) [3 months post intervention]
time (in minutes) a person spends awake during the night, starting from the time the person falls asleep; derived from actigraphy monitoring; more WASO indicates worse sleep
- Total sleep time (TST) [immediately post intervention]
Actual time (in minutes) a person is asleep during the nighttime sleep period; derived from actigraphy monitoring; normal sleep ranges from 420-480 minutes
- Total sleep time (TST) [3 months post intervention]
Actual time (in minutes) a person is asleep during the nighttime sleep period; derived from actigraphy monitoring; normal sleep ranges from 420-480 minutes
- Sleep efficiency (SE) [immediately post intervention]
Percent of time spent in bed that a person is asleep; calculated from actigraphy (time asleep/ time in bed)x 100%; lower SE indicates worse sleep
- Sleep efficiency (SE) [3 months post intervention]
Percent of time spent in bed that a person is asleep; calculated from actigraphy (time asleep/ time in bed)x 100%; lower SE indicates worse sleep
- Self- reported insomnia symptoms [immediately post intervention]
measured with the Insomnia Severity Index; score ranges from 0-28, with higher scores indicating more insomnia symptoms (thus worse outcomes)
- Self- reported insomnia symptoms [3 months post intervention]
measured with the Insomnia Severity Index; score ranges from 0-28, with higher scores indicating more insomnia symptoms (thus worse outcomes)
- self-reported sleep quality [immediately post intervention]
measured with Pittsburgh Sleep Quality Index; score ranges from 0-21 with higher scores indicating poor sleep quality (worse outcomes)
- self-reported sleep quality [3 months post intervention]
measured with Pittsburgh Sleep Quality Index; score ranges from 0-21 with higher scores indicating poor sleep quality (worse outcomes)
Other Outcome Measures
- Inflammatory Biomarkers including cytokines (IL-6, IL-1ß, TNF-α) and C-reactive protein (CRP) [Immediately post intervention]
Systemic inflammatory markers will be assayed using dried blood spots (DBS). DBS provides an easy to obtain, transport, and analyze blood source. Our Translational Core Laboratory utilizes a matrix independent platform (Mesoscale Discovery, Rockville MD), to support the assay of DBS for systemic inflammatory markers. Participants who have trouble with the finger prick will be provided with verbal assistance at sample pick-up while the researcher maintains physical distance.
