The purpose of this study was to investigate the effectiveness of robot-based interventions for the elderly. To this end, 10 related papers were selected as the analysis subjects and a meta-analysis was conducted. The overall effect size of robot-based interventions for the elderly was .40, showing a significant effect size of medium size. As a result of meta-analysis of variance to investigate the moderator variables affecting the effect size, the effect size of mechanical robots (g=.47) was found to be larger than that of social robots (g=.40). Among the dependent variables, cognition and social support did not show significant effect sizes, but depression (g=.51), activities of daily living (g=.49), social behavior (g=.47), and quality of life (d=.27) showed significant effect sizes (p<.05). There was a significant difference in the effect size according to the intervention environment, and the effect size when the intervention was conducted at home was significantly larger than when the intervention was conducted in other places. The effect size of intervention 7 times a week was significantly larger than that of interventions of other frequencies. The results of this study demonstrate that robot-based interventions targeting the elderly are effective, and suggest that consideration should be given to dependent variables, intervention environment, and frequency of intervention when implementing intervention programs.
