AB  - <b>Objectives:</b> Population aging is occurring at a rapid speed all over the world, bringing considerablepublic health challenges, including for the mental health of older adults. Considering that older populations are proneto depression and stress, the need for efective preventive interventions is critical. Tus, we conducted a study aimedat exploring the preventive impact of a community-based Tai Chi program over 8 weeks on depression and perceivedstress in healthy older adults in South Korea. <b>Methods: </b>A quasi-experimental design was utilized, with 63 olderadults participating (31 individuals in the Tai Chi group and 32 in the control group). Te Tai Chi intervention wasa supervised session 3 times per week. Data were obtained anonymously at baseline and post-intervention (week 8),with validated measures, including the Geriatric Depression Scale and the Korean version of the Brief EncounterPsychosocial Instrument. Data analysis included frequency distributions, descriptive statistics, and repeated measuresanalysis of variance to examine group× time interaction efects. <b>Results:</b> Baseline characteristics were comparablebetween groups. A repeated measures analysis of variance revealed signifcant group× time interaction efects fordepression (Wilks’ Lambda = 0.868, <i>F</i><sub>1</sub>, 57 = 8.63, <i>p</i> = 0.005, partial <i>η</i><sup>2</sup> = 0.13) and perceived stress (Wilks’ Lambda= 0.831, <i>F</i><sub>1</sub>, 57 = 11.62, <i>p</i> = 0.001, partial <i>η</i><sup>2</sup> = 0.17). In particular, participants in the Tai Chi group had signifcantlygreater reductions in depression and perceived stress than participants in the control group. <b>Conclusions:</b> Tese resultssuggest that Tai Chi may contribute to more favorable changes in depression and perceived stress among healthy olderadults compared to no intervention, suggesting its usefulness as a culturally appropriate intervention for sustainableenhancement of mental health and successful aging in rapidly aging societies, including South Korea.
