Effectiveness of Robot-Assisted Board Games on Cognitive Function and Mental Health for Older Adults with Mild Cognitive Impairment: A Cluster Randomized Trial

The effectiveness of robot-assisted board games targeting older adults with mild cognitive impairment was investigated to improve their cognitive function, general self-efficacy, and life satisfaction and reduce depression. A quasiexperimental research design was adopted with 109 older adults from 8 long-term care facilities and day-care centers assigned to the experimental (n = 52) and comparison groups (n = 57). The experimental group underwent a 12-week cognitive training program. Both groups completed before-and-after and 3-month follow-up measurements for outcome variables, including cognitive function (scores of mini-mental state examination [MMSE] and Alzheimer's Disease Assessment Scale Cognitive Subscale [ADAS-Cog]), depression, general self-efficacy, and life satisfaction. The data were analyzed using the generalized estimating equation (GEE). The program's usability was assessed using the system usability scale (SUS). The GEE analyses revealed significant postintervention improvements in the experimental group's MMSE, ADAS-Cog, depression, general self-efficacy, and satisfaction with life scores. These effects persisted for the 3-month follow-up. The mean SUS score was 87.50, indicating the feasibility of robot-assisted interventions among older adults. These findings confirmed that interactive robot-assisted board games can improve cognitive function, general self-efficacy, and life satisfaction and reduce depression among older adults. The administration of long-term care facilities or day-care centers can adopt robot-assisted board games as a training tool to supplement health promotion activities to prevent cognitive deterioration and enhance mental health among older adults.
