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

AIM: 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. BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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. IMPLICATIONS FOR NURSING MANAGEMENT: 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.
