Brief Summary
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

Outcome Measures
Primary Outcomes (5)
Insomnia severity index
Change in Insomnia Severity Index. ISI range from 0 to 28, higher score means more severe insomnia symptoms.
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Subjective cognitive impairment based on cognitive failure questionnaire
Change in Cognitive Failure Questionnaire (CFQ) total score as well as number of items with a score ≥ 3. The CFQ comprises 25 items and total score corresponds to the sum of all completed items, total score range from 0 to 100.
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Objective cognitive performance based on a composite score for executive functions from the CANTAB
Change in the Cambridge Neuropsychological Test Automated Battery (CANTAB) executive functions composite score (Intra-Extra Dimensional Set Shift \[IED\] and Stocking of Cambridge \[SOC\], ranging from 0 to 100 with higher scores reflecting poorer executive functions.
At baseline and at 24 weeks after the start of the intervention
Geriatric anxiety index
Change in Geriatric anxiety index. GAI scores range from 0 to 20 and higher scores mean more severe anxiety symptoms.
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Geriatric depression scale
Change in Geriatric depression scale. GDS scores range from 0 to 15, higher scores mean more severe depression symptoms.
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Secondary Outcomes (33)
Sleep quality based on the Pittsburgh sleep quality index
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Objective sleep measures based on actigraphy: Sleep Efficiency
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Objective sleep measures based on actigraphy: Sleep Latency
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Objective sleep measures based on actigraphy: Total Sleep Time
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
Objective sleep measures based on actigraphy: Wake After Sleep Onset
At baseline, at 10-12 weeks and at 24 weeks after the start of the intervention
- +28 more secondary outcomes
Study Arms (2)
online cognitive behavioral therapy for insomnia, anxiety and depression
EXPERIMENTAL10 self-directed modules of cognitive behavioral therapy for insomnia, anxiety and depression, delivered online, once a week
online intervention on nutrition and communication in older age
ACTIVE COMPARATOR10 self-directed modules on healthy nutrition habits and communication strategies, delivered online, once a week
Interventions
This intervention addresses insomnia, anxiety and depression via modules covering all the core CBTi components: psychoeducation about insomnia, relaxation, cognitive restructuring, stimulus control, sleep restriction and stress management; as well as psychoeducation about anxiety and low mood, behavioral activation strategies, and strategies to better manage ruminations. The modules are adapted to older adults and include short texts, pictures, quizzes with feedback, interactive exercises, logbooks, audio and video recordings.
This intervention addresses healthy nutrition habits as well as communication and aging. The modules are adapted to older adults and include short texts, pictures, quizzes with feedback, interactive exercises, logbooks, audio and video recordings

- 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
