This study aimed to explore changes in social participation and mental health among older adults during and after the COVID-19 pandemic in Taiwan, focusing on the relationship between social engagement and overall well-being. A two-wave study design was utilized, collecting data during both the pandemic (September 2021-June 2022) and post-pandemic period (September 2023-June 2024). Statistical analyses included paired t-tests and generalized estimating equations. The study was conducted in Yunlin County, Taiwan. The sample consisted of 345 community-dwelling adults aged 55 years and older residing in rural areas. Social participation was assessed using a 12-item measure. Additional assessments included scales for psychological symptoms, happiness, and quality of life. Older adults exhibited higher levels of social participation and better mental health and quality of life post-pandemic compared to the pandemic period. Significant growth was observed in activities such as voluntary work, cultural participation, and social clubs. Social participation levels were positively associated with psychological well-being and all domains of quality of life after controlling for demographic factors. Higher levels of social engagement were significantly associated with better mental health and quality of life scores. This study suggests that social participation is a relevant correlate of mental health and quality of life among older adults.
