Adult patients with chronic insomnia were recruited from the Sleep Medicine Center of Sichuan Provincial Center for Mental Health. Participants in the training group received 10 sessions of hospital-based happy sensation training group therapy and three months of home exercises. The control group received health instruction. Results included anxiety, depression, and insomnia and were assessed at baseline, 2-week intervention, and 3-month follow-up. Polysomnography was performed at baseline and 2-week intervention. Two-way repeated measure ANOVA and Nonparametric test were used for data analysis.Results42 patients in the training group and 43 patients in the control group accomplished 3-month follow-up. There was no significant difference in anxiety, depression, insomnia and sleep Characteristics between training group and control group at baseline (P > 0.05). Compared with the control group, anxiety, depression and insomnia were improved in the training group after 2 weeks and at the 3-month follow-up (P < 0.05), sleep latency was shortened (P < 0.001), and sleep efficiency, total sleep time and N2 phase sleep were increased (P < 0.05).ConclusionHappiness sensation training group can effectively improve the anxiety and depression of chronic insomnia patients, so as to improve insomnia. Given its acceptability and practicality, the program could be incorporated into routine treatment.Clinical trial registrationhttps://www.chictr.org.cn/bin/project/edit?pid=210919, identifier ChiCTR2400082199.
