Dynamics of Constructs in Successful Aging of Korean Elderly: Modified Rowe and Kahn's Model

Abstract

OBJECTIVES: This study examined components in Rowe and Kahn's successful aging model to investigate their hierarchical order and led to a modification of the previous hierarchical order. METHODS: To examine the hierarchical order of components, we constructed a structural equation model and verified those paths that have discrepancies in studies and/or potential inclusion or omission errors in the model. For this purpose, we analyzed 556 cases out of stratified and purposively sampled 600 elderly people living in the city of Jeonju during the study period (2011). RESULTS: The paths with inclusion errors such as H3 [self-reported health → productive activity (SRH → PA)]: the effect of SRH on PA, and H6 [social network (SN) → PA]: the effect of SN on PA, were not directly but indirectly supported. The path with discrepancy, H4 [SN → physical-cognitive function (PCF)]: the effect of SN on PCFs, was statistically significant. The path with inclusion error and discrepancy, H8 (PCF → PA): the effect of PCF on PA, was not directly but indirectly supported. Also the path with the omission error, H2 [SRH → psychological trait (PT)]: the effect of SRH on PT, was statistically significant. The other paths in the hierarchical order of the model reported in previous studies were statistically significant. CONCLUSION: We verified new dynamics of constructs involved in successful aging, which would provide better understanding of Rowe and Kahn's successful aging model for Korean elderly people living in a medium-sized city.
