Detailed Description
This study aims to examine the effectiveness of a fully-automated web and app-based digital CBT-I for insomnia compared to sleep hygiene education (SHE) in individuals with a diagnosis of insomnia disorder. Primary outcomes of interest include changes in insomnia severity, sleep onset latency, and wake after sleep onset throughout the course of the study.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Digital CBT-I Digitally-delivered CBT for insomnia accessed via web and/or mobile app |
Device: digital CBT-I
A fully-automated and personalized digital intervention based on principles from cognitive behavioral therapy for insomnia.
|
| Active Comparator: Sleep hygiene education This group will receive access to sleep hygiene education delivered via digital written materials |
Other: Sleep hygiene education
Participants will be provided with sleep hygiene advice which will be delivered digitally all at once upon allocation to the SHE arm. Participants will be able to revisit content during the trial as they wish.

Outcome Measures
Primary Outcome Measures
- Change in the Insomnia Severity Index (ISI) [From baseline to 10 weeks post-randomization]
Validated questionnaire; a 7-item scale with total scores between 0 and 28 where higher scores indicate greater severity
- Change in sleep onset latency (SOL) [From baseline to 10 weeks post-randomization]
Measured by daily sleep diaries (based on the Consensus Sleep Diary) averaged across 10 days
- Change in wake after sleep onset (WASO) [From baseline to 10 weeks post-randomization]
Measured by daily sleep diaries (based on the Consensus Sleep Diary) averaged across 10 days
Secondary Outcome Measures
- Insomnia Disorder remission (score <8) and response (change ≥6) on the ISI [10, 16, and 24 weeks post-randomization]
Validated questionnaire; a 7-item scale with total scores between 0 and 28 where higher scores indicate greater severity
- Insomnia disorder remission based on the SCID Insomnia Module [Week -1 compared to weeks 10, 16, and 24 post-randomization]
structured interview to assess for Insomnia Disorder
- Change in sleep diary parameters: percent sleep efficiency (SE), total sleep time (TST), total time in bed (TTIB), and total wake time (TWT) [From lead-in period to 10, 16, and 24 weeks post-randomization]
Each measured in minutes by daily sleep diaries (based on the Consensus Sleep Diary)
- Change in the Sleep Condition Indicator (SCI-8) [From baseline to weeks 10, 16, and 24 post-randomization]
Validated questionnaire; an 8-item scale with total scores between 0 and 32 where higher scores indicate better sleep
- Change in the Generalized Anxiety Disorder Questionnaire (GAD-7) [From baseline to weeks 10, 16, and 24 post-randomization]
Validated questionnaire; a 7-item scale with total scores between 0 and 21 where higher scores indicate greater severity
- Change in the Patient Health Questionnaire (PHQ-8) [From baseline to weeks 10, 16 and 24 post-randomization]
Validated questionnaire; an 8-item scale with total scores between 0 and 24 where higher scores indicate greater severity
- Change in the Insomnia Severity Index (ISI) [From baseline to weeks 16 and 24 post-randomization]
Validated questionnaire; a 7-item scale with total scores between 0 and 28 where higher scores indicate greater severity
- Change in sleep onset latency (SOL) [From baseline to weeks 16 and 24 post-randomization]
Measured by daily sleep diaries (based on the Consensus Sleep Diary) averaged across 10 days
- Change in wake after sleep onset (WASO) [From baseline to weeks 16 and 24 post-randomization]
Measured by daily sleep diaries (based on the Consensus Sleep Diary) averaged across 10 days
