Study of Cognitive Correction and Stimulus Control to Improve Sleep in Adults With Chronic Insomnia and Sleep Behavior Problems

What this Trial Is About

Researchers are evaluating the effects of cognitive correction and stimulus control on improving sleep cognitive distortions and maladaptive sleep behaviors in adults with chronic insomnia. The study focuses on changing incorrect beliefs about sleep, such as unrealistic sleep needs and worries about insomnia, and modifying behaviors to associate the bed with quick sleep onset rather than wakefulness. This trial is led by Xuanwu Hospital in Beijing and aims to understand how these behavioral approaches can improve sleep quality. Participants are randomly assigned to one of two groups one receiving cognitive correction combined with stimulus control, and the other receiving sleep hygiene education. Cognitive correction includes changing unrealistic sleep expectations and avoiding compensatory behaviors, while stimulus control involves strategies like using the bed only for sleep and sexual activities and getting out of bed if unable to sleep within 20 minutes. The sleep hygiene education group learns about healthy habits such as maintaining regular exercise, avoiding caffeine and alcohol at night, and creating a comfortable sleep environment. During the study, participants sleep quality and related symptoms are assessed using various questionnaires and scales, including the Pittsburgh Sleep Quality Index PSQI, Insomnia Severity Index ISI, and Dysfunctional Beliefs and Attitudes about Sleep Scale DBAS. These assessments occur at baseline and multiple follow-up points up to 12 months. The study also monitors changes in mood, pleasure, and life events. The main measurement is the change in PSQI scores after 6 weeks, with extended follow-up continuing for up to 24 months to assess long-term effects and safety.
