The goal of this clinical trial is to evaluate the effectiveness of an 8-week mindfulness lifestyle social prescribing program in community-dwelling older adults aged 55 and older. The main questions it aims to answer are:

To establish a mindfulness lifestyle social prescribing model applied to the psychological and social health promotion of middle-aged and older populations.

To evaluate the effectiveness of the intervention on improving depressive symptoms, loneliness, and quality of life in this population.

Participants will receive an 8-week group intervention program, with each weekly session lasting approximately 3 hours. The structured curriculum integrates mindfulness awareness, body scanning, mindfulness stretching, breathing training, healthy dietary education, and art practices (such as herbal therapy and leaf printing). Researchers will collect and evaluate data from pre- and post-intervention assessments to measure changes in depressive symptoms, loneliness risk, and overall quality of life.

This clinical trial implements an 8-week mindfulness lifestyle social prescribing program designed to enhance the psychological and social well-being of community-dwelling older adults. The intervention integrates mindfulness practices with healthy lifestyle modifications to address sub-healthy states, such as depressive symptoms and social isolation, which traditional clinical models often fail to fully resolve.

The structured 8-week group curriculum meets weekly for 3 hours per session. The program systematically incorporates mindfulness awareness, body scanning, mindfulness stretching, breathing training, healthy dietary education, and art practices (including herbal therapy and leaf printing).

The program is delivered by a multidisciplinary team of geriatricians, geriatric case managers, nutritionists, exercise instructors, and trained volunteers to ensure comprehensive support.

Research procedures involve a pre- and post-intervention assessment design. Participants will undergo standardized evaluations before the commencement of the first session (Week 1) and upon the completion of the program (Week 8). These assessments will objectively measure changes in depressive symptoms, the risk of loneliness, and overall quality of life to determine the effect of this social prescribing model.
