Our study aims to assess life satisfaction and evaluate its relationship with depression, nutritional status and cognitive function among the elderly. This study is a pathway analysis study using 9089 elderly people and was conducted as a supplemental analysis using the data from the 2017 Korean Elderly Examination Survey. As a result, depression, nutritional status, cognitive function and life satisfaction showed significant correlation. Nutritional status(.46, p=.007), and cognitive function(-.27, p=.014) were directly affected by depression. Both nutritional status(.08, p=.009) and cognitive function(-.03, p=.010) had effect on life satisfaction but life satisfaction was mediated by nutritional status and cognitive function in affecting to life satisfaction. It suggests that nursing intervention is needed for nutritional status and cognitive function for life satisfaction of the elderly.

The purpose of this study was to validate the Korean version of RESPECT-Music, which measures personal, social and cultural function of music, and to examine the correlation between the measured RESPECT data and the data measured from other scales for emotions. A survey was conducted with two separate groups of undergraduate students. Exploratory factor analysis with sample A (N=212) and confirmatory factor analysis and correlation analyses with sample B (N=296) were conducted. The result of exploratory factor analysis generated 10 factors as influential factors in music use, which was the similar results to the original scale: background, values, focus, dancing, family bonding, cultural identity, political attitudes, venting, emotional expression and social bonding. In the confirmatory factor analysis, this 35-item measurement was found to obtain adequate internal consistency and reliability. In addition, the correlations were found with other scales measuring emotional adjustment. Specifically, RESPECT showed a positive correlation with scales for positive affect, reappraisal, negative mood regulation and repair. Among the generated factors as music function, dancing was highly correlated with emotional adjustment, while political attitudes was negatively correlated with emotional adjustment. The results indicate that music use in our everyday lives is intercorrelated with the intrapersonal and interpersonal motives and emotional adjustment, while the function of music that influences cultural identity was not associated with the level of emotional adjustment. Implications for future studies were also suggested.
