Brief Behavioral Therapy for Insomnia(BBTi) in Middle-aged and Older Adults With Chronic Insomnia

The intervention consists of four weeks of BBTi. During the first week, participants will receive face-to-face sleep assessments and sleep hygiene education. In the second week, a phone interview will be conducted to assess the patient's progress and provide appropriate relaxation techniques. Unsatisfactory responses to sleep restriction therapy or stimulation control methods will be addressed through face-to-face interviews in the third week. The fourth week will involve an overall review and evaluation conducted via a telephone interview.
