The purpose of this study was to investigate the relationship between three internal marketing practices and service quality. This research adopts a cross-sectional design to examine the relationship between internal marketing and service quality with structural equation modelling. The result of the research clearly shows that there are significant positive relationships between internal marketing practices and service quality. In particular, the results of the present research demonstrate that training programmes have a strong association with service quality. However, the relationship from performance incentives to service quality was not found. Consequently, to deliver excellence service to patients, a hospital must provide training programmes and establish a clear vision about service excellence to nurses.
