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.
Interventions
The automated software called 'resleep' incorporates all core elements of CBT-I: sleep restriction, stimulus control, cognitive therapy, relaxation techniques, and sleep hygiene and education, tailoring content based on each participant's reported baseline sleep function and sleep progress. The 6-week treatment includes 42 times of intervention.
Subjects in the control group will receive non-tailored information about insomnia and sleep health education content using the Wechat Official Account.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| Life Quality | Baseline, post-intervention, follow-up (3 months after post-intervention) | WHOQOL-BREF is used to evaluate the life quality. |
| Sleep Quality | Baseline, post-intervention, follow-up (3 months after post-intervention) | Pittsburgh Sleep Quality Index (PSQI) is used to assess overall sleep quality. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Adverse Events | Baseline, post-intervention, follow-up (3 months after post-intervention) | Adverse events will be recorded throughout this trial for evaluating the safety of software. |
