Environmental Volunteerism for Social Good: A Longitudinal Study of Older Adults’ Health

Natural disasters and aging societies are increasingly prevalent globally. To improve environmental injustice and contribute to social good, the Tzu Chi Recycling Program engages older adult volunteers in recycling usable materials into eco-friendly blankets for disaster survivors. Drawing on life span and ecological systems theories, this study examined the longitudinal effects of this program on older adults’ mental and physical health. Using a quasi-experimental longitudinal design, data were collected from older adults at recycling stations (intervention group, n = 36) and community centers (control group, n = 36) in rural areas in Southern Taiwan. Findings from two-way repeated measures analysis of variance show that the program significantly improved older adults’ self-compassion, compassion for others, depression, hostility, happiness, and hypertension. Older adults built resilience and contributed to environmental sustainability and social good, which suggest a new avenue for social work practitioners and policy-makers to address social and environmental challenges.
