Purpose: This study was conducted to investigate changes in cognitive functions, depression and life-satisfactionfor elderly participants with mild cognitive impairments participating in an individual cognitive improvementprogram. Methods: A quasi-experimental with non-equivalent control group pretest-posttest design wasimplemented. The participants were senior citizens over 65 years of age who had been clinically diagnosed withmild cognitive impairments in G City and J Province (experimental group: 29, control group: 27). The experimentalgroup participated in the individual cognitive improvement program based on Korean traditional tales and gamesfor nine weeks. Results: After the intervention, only the participants in the experimental group reported significantimprovement in K-MMSE (t=-2.5, p=.016), MoCA-K (t=-2.6, p=.008), depression (t=3.51, p=.001), and life satisfaction(t=-2.75, p=.008) when compared to those in the control group. Conclusion: These results indicated thatthe individual cognitive improvement program was effective in improving cognitive functions, depression, andlife-satisfaction among the elderly with mild cognitive impairments. Therefore, the application of this individualcognitive improvement program developed in this study by visiting nurses may strengthen the cognitive functionsof seniors with mild cognitive impairments.
