Improving Sleep to Protect Brain Health in Older Adults: Assessing a Novel Cognitive-behavioral Program for Insomnia Using a Multidomain Web Platform
The goal of this randomized controlled clinical trial is to assess a novel cognitive-behavioral program for sleep and mental health using a multidomain web platform (eCBTi+) in participants with insomnia and subjective cognitive complaint. The main questions it aims to answer are: * Whether the eCBTi+ intervention improves sleep (subjective: Insomnia severity index \[ISI\], objective: EEG-based sleep efficiency) sleep and mental health (Geriatric Anxiety Index \[GAI\] and Geriatric Depression Scale \[GDS\]) compared to the control intervention * Whether the eCBTi+ intervention improves cognitive abilities (subjective: Cognitive Failure Questionnaire \[CFQ\], objective: CANTAB executive functions composite score) compared to the control intervention
• age 60 years or older at the time of enrolment
• Sleep Condition Indicator, SCI ≤ 16 and/or meeting DSM-V criteria based on the symptoms assessed by the SCI
• subjective cognitive complaints (self-report version of Everyday Cognition scale (ECog), score ≥ 2 on any item)
• ability to read and understand French or English
• ability to use a smartphone or tablet, and access to home internet connection
• If on hypnotic or psychotropic medication (including cannabis), being on stable dosage for at least 2 months prior to study entry
• Score on the STOP-BANG questionnaire \< 3 corresponding to participants with low risk of obstructive sleep apnea
