Study of Sleep Restriction and Stimulus Control to Improve Sleep Habits in Adults with Chronic Insomnia

What this Trial Is About

Researchers are evaluating how sleep restriction and stimulus control can improve sleep habits and reduce unhealthy sleep behaviors in people with chronic insomnia. The study focuses on patients with prolonged time in bed and maladaptive sleep patterns, aiming to enhance sleep efficiency and quality. This study is interventional and compares two behavioral approaches to managing insomnia. The study tests two behavioral treatments sleep restriction and stimulus control versus sleep hygiene education. Sleep restriction involves limiting time in bed to match actual sleep time but not less than 4.5 hours, avoiding naps, and maintaining a regular wake-up time. Stimulus control helps patients associate their bed with falling asleep quickly by only using the bed for sleep and sexual activity, leaving the bedroom if unable to sleep within 20 minutes, and waking up at a consistent time daily. The comparison group receives sleep hygiene education focusing on healthy habits such as regular exercise, comfortable bedroom environment, and avoiding stimulants before bedtime. Participants will be assessed using the Pittsburgh Sleep Quality Index PSQI at baseline and after 6 weeks for the primary outcome, with additional follow-ups up to 24 months for various secondary measures including sleep efficiency, insomnia severity, mood, and quality of life. Evaluations include sleep diaries, questionnaires on maladaptive sleep behaviors, and multiple health and psychological scales. The study uses a randomized, double-blind design and involves regular monitoring to track changes in sleep and related health aspects throughout the study duration.
