The Effect of Job Demands, Job Resources, and Musculoskeletal Complaints on Presenteeism Among the Dependent Self-employment Workers in Korea: Testing of a Mediation and Moderation Model.

Abstract

We tested the effects of job demands on presenteeism to investigate the mediation of musculoskeletal complaints (MSCs) and the moderating effects of job resources among dependent self-employment (DSE) workers in Korea. Using data from the fifth Korean Working Conditions Survey, we analyzed 2252 workers, and a two-step regression analysis was used to test the mediated effect of MSCs and moderated the effect of job resources on the relationship between job demand and presenteeism. Musculoskeletal complaints mediate the relationship between job demands and presenteeism. Job control moderated the relationship between MSCs and presenteeism among the job resources. However, the conditional indirect effect of job demands on presenteeism through MSCs was independent of job resource levels among DSE workers. Various strategies are needed to address MSCs and enhance job resources for DSE workers, which might diminish the negative effect of job demands on presenteeism.
