Horticultural Therapy Support Group for Older Adult Caregivers: Examining Intervention Effectiveness Using Psychometrically Validated Measures

This two-year study explored how gardening-based therapy could improve the well-being of people with end-stage kidney disease who were undergoing regular hemodialysis. Patients participated in a 14- to 16-week therapeutic horticulture program held in a greenhouse at the University of Florida. Activities included planting, harvesting, garden education, and plant-based crafts. The researchers used a health survey (KDQOL-SF) to track changes in how participants felt about their physical health, emotional state, and the burden of living with chronic kidney disease.

The study found that participants felt less overwhelmed by their illness and more physically capable after just eight weeks in the program. These improvements were sustained through the end of the program, though some benefits faded two months after the sessions ended. The program also offered emotional support and a sense of purpose by allowing participants to contribute plants to the community or sell them to support future programs. Despite health challenges, many patients found value in the sessions and wished they had lasted longer.
