Wearable Voice-Guided BBTi for Comorbid Insomnia and Sleep Apnea (COMISA)

Краткое описание

This study investigates the efficacy of a wearable voice-guided Brief Behavioral Therapy for Insomnia (BBTi) combined with a smart eye-mask device for individuals with Comorbid Insomnia and Sleep Apnea (COMISA). The four-year study comprises three phases: (1) exploration of cognitive-emotion regulation-arousal system mechanisms in COMISA and pilot BBTi intervention testing, (2) development and usability testing of an integrated smart eye-mask with BBTi voice-guided modules, and (3) a multi-center randomized controlled trial (RCT) evaluating the combined BBTi plus smart eye-mask intervention versus BBTi alone, smart eye-mask alone, and standard sleep hygiene education in 160 COMISA participants. Primary outcomes include insomnia severity (ISI), daytime sleepiness (ESS), and CPAP adherence. The study aims to establish an evidence-based digital health intervention for improving sleep outcomes in COMISA patients.
