Abstract

Purpose

The aim of this study was to evaluate the effects of a computerized cognitive training on older adults affected by mild cognitive impairment (MCI) in terms of cognitive function, depression, self-esteem, and activities of daily living (ADL).

Methods

This study used a non-equivalent control group non-synchronized design. A total of 53 older adults who reside in long-term care facilities were recruited, 26 subjects for an experimental group and 27 subjects for a control group. A computerized cognitive training was performed for 20~40 minutes/day, three days/week for ten weeks. Data were analyzed using SPSS/WIN 21.0 with x² test, Fisher's exact test, and t-test.

Results

Scores of MMSE (t=3.30, p=.002), depression (t=-2.15, p=.036), and self-esteem (t=2.76, p=.008) were significantly better in the experimental group than the control group. However, the difference in ADL (t=-1.01, p=.316) was not significant between the two groups.

Conclusion

These findings suggest that the computerized cognitive training can be used as an effective nursing intervention to improve cognitive function and self-esteem and lower depression among older adults with MCI.
