Full description

This is a single-center, randomized, open, parallel controlled study. Patients who had no CBTI treatment before for chronic insomnia will be recruited and followed for 6 weeks. Participants will be random allocation into Group dCBT-I and Group Sleep Education, and then explore the clinical effectiveness of smartphone-based digital CBT-I therapy. We will collect the baseline information: population characteristics, including age, sex, education, employment, living and residential status, demographic data, smoking and alcohol consumption, body mass index (BMI); medical history and medication status and adverse reactions during treatment. Primary outcome is the Insomnia Severity Index (ISI). Secondary outcomes include an online sleep diary measured information regarding: time in bed(TIB), total sleep time (TST), sleep efficiency (SE), total wake time(TWT); bracelet measured information regarding: total sleep time (TST), sleep latency(SL), sleep efficiency (SE), the times of wake from sleep(TWS), sleep quality score setting by bracelet; the 16-item Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS-16); Fatigue Severity Scale(FSS); Health-related Quality of Life (SF-12); Generalized Anxiety Disorder Scale-7 (GAD-7); Patient Health Questionnaire-9 (PHQ-9).
