수도권 근로자의 통근시간이 삶의 만족도에 미치는 영향: 시간부족감과 피로감의 조절된 매개효과

This research examines whether the commuting time of full-time metropolitan workers can harm their life satisfaction using the 2014 Time Use Survey. Especially, this study predicted that commuting time will affect life satisfaction adversely through perceived time inadequacy with the perception of time inadequacy moderated by the experience of fatigue. First, ANOVA was used to determine whether there is a significant group difference in commuting time depending on demographic variables such as gender, education, marital status, housing type, annual income, industry, and occupation. Next, the proposed moderated mediation model was examined using Hayes’ (2012) PROCESS macro. Results showed that men, 20's, unmarried, college graduates, monthly income group of 4-5 million won, owned residents, managers, and office workers were found to have significantly longer commuting time than the other groups. However, the number of preschool children or children under 10 did not make a difference in commuting time. The analysis of the moderated mediation model confirmed the proposed relationship: Commuting time was found to have a negative effect on life satisfaction through perceived time inadequacy. In addition, the relationship between commuting time and perceived time inadequacy was moderated by fatigue: It was the group with low fatigue who perceived more time inadequacy as commuting time increased, which implies that the low-fatigue group is more susceptible to the adverse effect of commuting time. Implications and limitation of the study were discussed.
