With global population aging, dementia prevention has become a major public health priority. This study evaluated the effects of an 8-week robot-assisted intervention on cognitive and psychosocial outcomes among community-dwelling older adults. A total of 80 participants aged 65 years and older were recruited from two community centers and assigned to either a robot-assisted intervention group (n = 40) or a usual care comparison group (n = 40). The intervention involved structured group sessions using a humanoid robot: Kebbi (NUWA Robotics). Cognitive function, social engagement, depressive symptoms, and loneliness were assessed. Data were analyzed using paired t-tests and generalized estimating equations. Results showed significant group × time interaction effects across all outcomes (p < .001). These findings indicate that robot-assisted intervention programs are effective in improving cognitive and psychosocial functioning and support their integration into comprehensive dementia prevention strategies.
