Life satisfaction analysis of occupational balance group: based on Korean time use survey data (KOSTAT) of older adults
Abstract Background: The purpose of this study was to identify whether there is a difference in time use between a group of subjects with occupational balance, the occupational balance group (OB group) and a group of subjects lacking occupational balance, the occupational imbalance group (OI group), and what factors influence the life satisfaction of the OB group. This study used raw data from the 2014 Time Use Survey of the Korea National Statistical Office (KOSTAT). Methods: This study sorted detailed activities of the 9.228 subjects who were over 65 years of age. We conducted an independent sample t-test to confirm the time difference by areas between the OB group and the OI groups. In order to confirm the effect of variables on life satisfaction, we performed regression analysis by applying an ordered probit model (OPM). Results: The analysis of time use corresponding to eight activity areas showed the greatest time use for the instrumental activities of daily living (IADL), followed by rest and sleep, leisure, and activities of daily living (ADL). The largest effect size (ES) was social participation, followed by leisure, IADL, and work. As a result of analyzing the factors affecting the life satisfaction of the OB group, we found that lower age, females, a higher level of education, a lower need for care, higher income, and agricultural residence tended to correspond to higher life satisfaction. Conclusions : This study may provide a basis for the development of the time‐use management and lifestyle redesign programs to assist older adults in pursuing disease prevention and health maintenance roles by themselves.
