Software-delivered CBT-I for Insomnia Disorder
- Conditions

- Registration Number
- NCT05747963
- Lead Sponsor
- Peking University Sixth Hospital
- Brief Summary
The goal of this prospective multicenter clinical trial is to evaluate the efficacy and safety of software-delivered cognitive behavioral therapy for insomnia (CBT-I) in Chinese patients with insomnia disorder (ID). The main questions it aims to answer are: (1) whether the software-delivered CBT-I is more effective than an online patient education (online-PE) at improving insomnia. (2) whether the software-delivered CBT-I is safe for treatment of insomnia symptoms.
Participants will be randomized to receive (1) a software-delivered CBT-I using automated software called 'resleep' (one kind of digital device expected to treat insomnia targeted for Chinese patients); (2) online patient education (online-PE) about sleep.
Researchers will compare the efficacy of a software-delivered CBT-I program and an online sleep education control at improving insomnia symptoms and other psychological outcomes.

Group Intervention Description software-delivered CBT-I software-delivered CBT-I Subjects in intervention group will receive a digital CBT-I for 6 weeks. The automated software incorporates all core elements of CBT-I, tailoring content based on each participant's reported baseline sleep function and sleep progress. online PE online PE Subjects in control group will receive information about insomnia and sleep health education content.
- Primary Outcome Measures
Name Time Method The Change of Insomnia Severity from Baseline to Follow-up Baseline, post-intervention, follow-up (3 months after post-intervention) The insomnia severity is assessed with the Insomnia Severity Index (ISI), a 7-item questionnaire well validated in insomnia research in multiple patient populations. The change of ISI scores from baseline to follow-up is the primary outcome.
- Secondary Outcome Measures
Name Time Method Insomnia Remission Baseline, post-intervention, follow-up (3 months after post-intervention) Insomnia remission was evaluated by a masked assessor using a semi-structured interview.
Sleep Quality Baseline, post-intervention, follow-up (3 months after post-intervention) Pittsburgh Sleep Quality Index (PSQI) is used to assess overall sleep quality.
Insomnia Treatment Response Baseline, post-intervention, follow-up (3 months after post-intervention) Insomnia treatment response was defined by a decrease in ISI by at least 8 points.
Anxiety Baseline, post-intervention, follow-up (3 months after post-intervention) Generalized Anxiety Disorder Scale-7 (GAD-7) is used to evaluate the severity of anxiety.
Depression Baseline, post-intervention, follow-up (3 months after post-intervention) Patient Health Questionnaire-9 (PHQ-9) is used to evaluate the severity of depression.
Sleep Parameters Assessed by Sleep Diary Baseline, post-intervention, follow-up (3 months after post-intervention) Sleep diaries related parameters include time taken to fall asleep (sleep onset latency), wake after sleep onset, total sleep, total time in bed, and sleep efficiency.
Life Quality Baseline, post-intervention, follow-up (3 months after post-intervention) WHOQOL-BREF is used to evaluate the life quality.
