Group-Based Brief Behavioral Therapy for Insomnia for Patients With Chronic Mental Illness

Effectiveness of a Group-Based Brief Behavioral Therapy for Insomnia for Patients With Chronic Mental Illness

The goal of this clinical trial is to evaluate the effectiveness of a short-term, group-based Brief Behavioral Therapy for Insomnia (BBTI) intervention in chronic psychiatric patients at a hospital day ward.The main questions it aims to answer are:

1. Does the BBTI-based group intervention improve subjective sleep quality and reduce the severity of insomnia?
2. Does the intervention have a positive effect on psychological well-being and cardiometabolic/physical functions? Researchers will compare an experimental group to a waitlist control group to see if the intervention improves sleep quality, reduces insomnia-perpetuating behaviors, and enhances overall health status across various timeframes.

Participants will:

1. Attend four sessions that cover sleep structure education, relaxation techniques (including acupressure), sleep-promoting diet principles, and the proper use of sedative-hypnotic medications.
2. Write a daily sleep diary.
3. Complete three times of structured self-report questionnaires.
4. Undergo physiological and physical function assessments.

Inclusion Criteria:

• Aged 18 years and older.
• Diagnosed with a psychiatric disorder.
• Experiencing self-reported sleep disturbances, such as difficulty initiating sleep, difficulty maintaining sleep, early morning awakening, prolonged sleep latency, short sleep duration, poor sleep efficiency, or the current use of sedative-hypnotic medications.

Exclusion Criteria:

• Severe intellectual disability resulting in the inability to complete the assessment questionnaires.
• Severe cognitive impairment (e.g., dementia) that prevents cooperation and participation in the intervention activities.
• Recent clinical instability, high suicide risk, or deemed unsuitable for participation by the primary attending physician.
