The purpose of this paper is to investigate the manner in which employees' experience of distributive justice (DJ) moderates the impact of intrinsic and extrinsic values on role engagement (RE). RE is especially important in the healthcare setting (examined here) due to the sector's complexity, changeability and emotionally challenging nature. Design/methodology/approach Using data collected from a survey of employees from a large government health district in Southeast Queensland (Australia), this study examined the determinants of RE among a group of employees working across three hospital locations. Findings The focus of the study was on the impact, both directly and in combination, of espoused extrinsic and intrinsic values and perceived DJ on RE. The authors identify strong direct effects from DJ on RE, and complex third-order effects for the combinations of intrinsic (IM) and extrinsic motivation and DJ in predicting RE. Research limitations/implications As a cross-sectional and attitudinal survey, care must be taken in relation to common-method variance. Post hoc controls were performed in relation to this.
