Occupational strain and job satisfaction: The job demand-resource moderation-mediation model in haemodialysis units.

Abstract

To examine whether job resources moderate the relationship between job demands and occupational strain, and whether occupational strain mediates the relationship between job demands and job satisfaction. The job demand-resource model suggests that job demands and job resources are related to occupational strain, and occupational strain is associated with job satisfaction. In 2018, a cross-sectional study was conducted with a convenience sample of 85 nurses from six haemodialysis units. Linear regression with moderation-mediation analysis was conducted using SPSS software. Under low workload levels, no association between autonomy and occupational strain existed, but under high workload levels, a negative relationship was found between autonomy and occupational strain. Under low workload levels, a negative relationship was found between social support and occupational strain, but under high workload levels, a positive relationship was found. Finally, there was no association between occupational strain and job satisfaction. Job resources are moderators of the relationship between job demands and occupational strain. However, there was no significant association between occupational strain and job satisfaction. Nurse leaders should strengthen nurses' autonomy, which can reduce occupational strain. Additionally, sources of support are needed to help nurses cope with the workload and occupational strain.
