Registration Number

Brief Summary

This randomized clinical trial on 60+ aged and independent-living healthy individuals with symptoms of insomnia will attempt to improve sleep and health outcomes related to sleep with enhancement of a clinical intervention, Cognitive Behavioral Therapy for Insomnia (CBTi).

Detailed Description

Telehealth-delivered enhanced CBTi (integrated with a sleep diary app, a therapist dashboard, and data from IoT devices) will be compared to standard telehealth CBTi and to usual treatment with sleep hygiene education. The investigators will determine effects on insomnia (primary outcome) and on clinical sleep metrics (secondary outcome), among other outcomes including cognitive performance, blood biomarkers of ADRD, and therapeutic adherence.

After screening consent and qualification, informed consent, and adherence evaluation with ambulatory devices (1wk), study participants are pseudo-randomized into one of 3 study arms (2:2:1, Enhanced CBTi : Standard CBTi : Sleep Hygiene). The living space of participants is equipped with IoT data collection devices. Participants take surveys related to sleep, have blood drawn, wear ambulatory devices, complete cognitive evaluations, and interact with nearable living space devices and an iPhone interface during a preparation week leading up to an intake telehealth appointment. Baseline data collection (1wk) occurs. Participants then adhere to behavioral therapy directives prescribed at weekly telehealth sessions with a clinically qualified therapist, take surveys related to sleep, complete cognitive evaluations, wear ambulatory devices, and interact with nearable living space devices and an iPhone interface throughout the study intervention period of 6 weeks. During the final week (coinciding with the 6th intervention week), participants have a second blood draw and return all study equipment/devices at the conclusion of participation.

Primary Outcome Measures
NameTimeMethod
Change in Insomnia Severity IndexScreening (at enrollment qualification) and Weekly (each of study weeks 1-8)

Subjective patient completion of the Insomnia Severity Index survey. Sum of survey item responses; Minimum score: 0; Maximum score: 28. Higher sum score indicates a greater number of, or more severe, insomnia symptoms; reduction in sum score suggests improvement of insomnia.

Secondary Outcome Measures
NameTimeMethod
Change in Sleep Maintenance EfficiencyNightly (each night throughout study weeks 1-8)

Objective ambulatory activity (actigraphy) and other biometric data will be collectively used to determine sleep state. From sleep state data, Sleep Maintenance Efficiency will be calculated (i.e. percentage of time between sleep onset and awakening for the main sleep period that is spent in the sleep state). Minimum score: 0% (i.e. no sleep); Maximum score: 100% (i.e. no awake time during the sleep window). Higher percentage score indicates that a greater proportion of the rest interval was spent actually asleep; increase in percentage score suggests improvement in sleep quality.

Change in Total Sleep TimeNightly (each night throughout study weeks 1-8)

Objective ambulatory activity (actigraphy) and other biometric data will be collectively used to determine sleep state. From sleep state data, Total Sleep Time will be calculated (i.e. total minutes of nocturnal sleep). An increase in sleep time indicates improvement in sleep quantity.

Change in Self-Reported SleepDaily (each morning throughout study weeks 1-8)

Subjective sleep diary data will be used to determine perceived sleep features (duration, quality, etc).
