11/3/2023 0 Comments Insomnia 2002 online![]() ![]() Cognitive behavioral therapy for insomnia (CBT-I) is the current recommended first-line treatment for insomnia among adults. 2 - 4 The combined global prevalence of insomnia is approximately 15% 5 and more than 200 million people in China experience insomnia. Insomnia is a common sleep problem 1 that affects health worldwide. Trial Registration Identifier: NCT04779372 Future multicenter clinical trials with large sample sizes are needed to validate its effectiveness in the Chinese population. Some of the sleep diary measures and self-reported scales showed more improvements in the DCBT-I group than sleep education group, such as total sleep time (mean : 3 months, 403.9 minutes vs 363.2 minutes 6 months, 420.3 minutes vs 389.7 minutes) and sleep efficiency (mean : 3 months, 87.4% vs 76.7% 6 months, 87.5% vs 78.1% ).Ĭonclusions and Relevance In this randomized clinical trial, the smartphone-based Chinese culture-adapted DCBT-I improved insomnia severity compared with sleep education. There were significant improvements from before to after the intervention for both the sleep education and DCBT-I groups, with large effect sizes(sleep education: d = 1.13 DCBT-I: d = 1.71). Mean (SD) ISI scores in the DCBT-I group were significantly lower than those in the sleep education group after the 6-week intervention (12.7 points vs 14.9 points Cohen d = 0.458 P = .048) and at the 3-month follow-up (12.1 points vs 14.8 points Cohen d = 0.489 P = .04). Results Of 82 participants (mean age, 49.67 years 61 females), with 41 randomized to sleep education and 41 randomized to DCBT-I 77 participants completed the 6-week intervention (39 participants in the sleep education group and 38 participants in the DCBT-I group full analysis data set) and 73 completed the 6-month follow-up (per protocol data set). Secondary and exploratory outcomes included sleep diary measures self-reported scales assessing dysfunctional beliefs about sleep, mental health, and quality of life and smart bracelet measures. Main Outcomes and Measures The primary outcome was Insomnia Severity Index (ISI) scores with the intention-to-treat principle. Interventions A Chinese smartphone-based app with the same interface was used in both DCBT-I and sleep education groups over 6 weeks, with 1-, 3-, and 6-month follow-ups. Data were analyzed from January to February 2022. After assessing for eligibility, eligible participants were enrolled and allocated (1:1) to DCBT-I or sleep education groups. Follow-up visits were performed online or in the same hospital. Screening and randomization were conducted at Peking University First Hospital. Objective To investigate the efficacy of a smartphone-based Chinese culture–adapted DCBT-I application (app) for insomnia compared with sleep education using the same app.ĭesign, Setting, and Participants This was a single-blinded, randomized clinical trial conducted from March 2021 to January 2022. Moreover, studies comparing DCBT-I and sleep education in the same operating interface are lacking.
