Impact of Employment and Age on Quality of Life of Individuals With Disabilities: A Multilevel Analysis

The purposes of this study are (a) to explore how people with disabilities (PWD) experience differences in their quality of life (QOL) over the course of their lives, (b) to examine the effect of employment on QOL, and (c) to investigate the impact of age on overall QOL for PWD both inter- and intra-individually. To address these aims, this study used the data set for the Panel Survey of Employment for the Disabled (PSED) collected by the Korean Employment Agency for the Disabled (KEAD). The target populations of the study were 5,092 registered persons with disability. No longitudinal approach to examine the impact of employment and age on QOL for individuals with disabilities has been considered in the previous literature. Thus, multilevel modeling was used to examine the relationship between employment, age, and QOL for PWD. Results of this study indicated that employment status and age were significant predictors of QOL among PWD. These findings call attention for the need to consider the impact of employment and age on QOL of PWD both inter- and intra-individually.
