The Role of Staff-Assessed Care Quality in the Relationship between Job Demands and Stress in Human Service Work: The Example of Dentistry.

The aim of this study was to investigate staff-assessed care quality at the clinic as a predictor of stress and as a moderator between job demands (quantitative demands and role conflict) and stress among dental professionals as an example of human service workers. Cross-sectional questionnaire data from 1012 dental professionals (i.e., dentists, dental hygienists and dental nurses) working at 99 clinics were analysed by confirmatory factor analysis and a two-level hierarchical linear model. Stress, quantitative demands and role conflict were measured by the Swedish standard version of COPSOQ III and care quality was measured by three proprietary items. The results showed that staff-assessed care quality at the clinic was of importance for the individual workers' experiences of stress. Furthermore, the staff's joint assessment of the care quality at the clinic mitigated the negative effect of role conflict on stress among dental nurses. These results indicate that a high level of staff-assessed care quality at the clinic can contribute to reduced stress in dental professionals.
