Stability and change model of job resources and work engagement: A seven-year three-wave follow-up study

Using the stability and change model, conservation of resources theory and the job demands-resources model, this study aimed to determine: (1) the extent to which work engagement and job resources can be explained by a component reflecting stability and a component reflecting change in these constructs, and (2) the strength and direction of the relationship between work engagement and job resources when their stable components are controlled for. The study was carried out among 1,964 Finnish dentists over a seven-year time period (2003–2010), using a three-wave dataset. Some of the dentists had changed jobs during the follow-up, and therefore the research questions were validated among groups of job stayers and job changers. The stability and change models were examined using structural equation modelling. The results showed that 69–77% of the variance of dentists' work engagement, and 46–49% of the variance of job resources was explained by the component reflecting stability. However, although there was a positive relationship between job resources and work engagement, the primary direction of this relationship could not be determined. Either job resources or work engagement may be considered as the initiator of this relationship. Job change did not affect the results.
