Clinical Trial Summary

This study will examine the effectiveness of digital CBT-I versus sleep hygiene education in reducing insomnia severity, sleep onset latency, and wake after sleep onset in those with insomnia disorder.

Outcome

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