IMPACT OF SOCIAL CONTACT AND PHYSICAL ACTIVITY ON DAILY EMOTION OF KOREAN URBAN OLDER ADULTS

In the notion of the activity theory of aging, this study investigated the impact of social contacts on daily emotions of Korean urban older adults. We also explored the relationship between the intensity of physical activities and daily emotional experiences. For these purposes, data was collected by multi-method approach. To answer the first question, the level of positive and negative emotions and the types of people older adults meet each day were collected for a week using daily-diary method(n=178). For the second purpose, number of steps and the intensity of the physical activities were collected for a week from 20 subsamples using activity monitors. Hierarchical linear modeling was used for the analysis. Results show that social contacts affect daily emotions but the impact differs by the people whom older adults meet. Contacts both with children and with friends elevate positive emotions, but for negative emotion, contact with children only shows lowering effect. And the impact of social contacts with children and neighbors are greater for those who live alone than their counterparts. In terms of physical activity, it is shown that longer sedentary time lowers the level of positive emotions Findings partially support activity theory, but it reveals that the impact of social contacts and physical activity is differed by whom they meet and the intensity of the physical activities. Noteworthy finding is that interaction with children is very important factor explaining the intra-individual changes of daily emotions for Korean urban older adults
