Clinical Trial Summary

The purpose of this study is to investigate the mechanisms of change in Cognitive Behavioral Therapy for insomnia (CBTi) in a sample of adults aged 50-65. This study aims to evaluate the pre-post treatment change in sleep, circadian rhythms, biomarkers, cognitive performance, and structural and functional magnetic resonance imaging scans (MRI).


Description:

Baseline Part 1: - Online demographic and contact information - Schedule Baseline Part 2 with the investigators via online link - 1 week of daily sleep diaries Baseline Part 2: - Internet-based interview with the investigators to confirm study eligibility requirements - Online self-report questionnaires - 2 weeks of daily sleep diaries - 2 weeks of sleep/wake assessment wearing a watch-like activity monitor (Actiwatch) Objective Baseline: - Single-night, diagnostic in-home sleep study, including and the following equipment: - Adhesive patch which will adhere to the arm - Sensor belts worn around the chest, fitted with nasal canula, pulse oximeter, and 3 electrodes which will adhere to the back of the neck and behind each ear - Next-day appointment: - Neuropsychological assessment - Structural and functional magnetic resonance imaging scan (MRI) - Non-invasive blood pressure readings - Low-volume Blood draw (used to obtain genetic biomarkers) - Removal of adhesive patch - Next-day evening (2-nights): - Consumable capsule - Sensor belt worn around the chest/abdomen Random Assignment: If it is determined the participant is eligible for the study, participants will be randomly assigned to one of the treatment groups (in-person, telehealth or internet delivered) or asked to wait to start treatment. Treatment Phase I: - Participants will complete up to 12 weeks of insomnia treatment or wait for treatment ("waitlist") 12-Week Post-treatment Part 1: - Complete 2 weeks of an online daily sleep diary and actigraphy - Complete online self-report questionnaires Objective 12-Week Post-treatment: • Repeat "Objective Baseline" outlined above Treatment Phase II (WLC): - Treatment will start for participants who had been assigned to the waitlist condition 3-Month Follow-Up: - Complete online self-report questionnaires

Intervention

Behavioral:
In-Person Cognitive Behavioral Therapy for Insomnia
Cognitive behavioral therapy is recommended as a first-line treatment for insomnia (CBTi). CBTi contains the following well-validated components of cognitive behavioral treatment for insomnia: stimulus control, sleep compression, sleep hygiene, relaxation training, and cognitive restructuring.
Telehealth Cognitive Behavioral Therapy for Insomnia
Telehealth cognitive behavioral therapy is recommended as a first-line treatment for insomnia (CBTi) conducted via audio-video communication. tCBTi contains the following well-validated components of cognitive-behavioral treatment for insomnia: stimulus control, sleep compression, sleep hygiene, relaxation training, and cognitive restructuring.
Internet Cognitive Behavioral Therapy for Insomnia
Sleep Healthy Using The Internet (SHUTi; aka iCBTi) is a self-guided, fully automated, online CBTi program that includes interactive features: personalized goal setting, graphical feedback based on inputted data, animations/illustrations to enhance comprehension, patient vignettes, and video-based expert explanations.
