[The effects of a cognitive enhancement group training program for community-dwelling elders]

In this study a cognitive enhancement group training program of 10 sessions was provided for community-dwelling elders and the effects on cognitive function, depression and quality of life were tested.

A quasi-experimental study using a nonequivalent control group, pre-post design was used. The participants were 87 elders whose cognitive function was within the normal range. Of these elders, 45 were assigned to the experimental group and 42 to the control group. The intervention was conducted once a week for 10 weeks. Chi-square test, t-test, paired t-test, Wilcoxon rank sum test and Wilcoxon signed rank test were used to analyze the data.

After the program, the cognitive function (t=-2.85, p=.006), depression (z=2.82, p=.005) and quality of life (t=2.79, p=.007) of the experimental group was significantly better than those of the control group. Especially, immediate recall (z=2.45, p=.014) and concentration (z=2.58, p=.010) in the subcategory of cognitive function were significantly better than that of the control group.

The findings indicate that the cognitive enhancement group training program was effective in enhancing the cognitive function, depression and quality of life for elders and could therefore be considered as a positive program for emotional and cognitive support for community-dwelling elders.
