Burnout and engagement as mediators in the relationship between work characteristics and turnover intentions across two Ibero-American nations

This study examines the mediating effects of burnout and engagement on the relationships between work characteristics (work overload and social support) and turnover intentions in the nursing community of two Ibero-American countries within the job demands-resources model. The sample consists of 316 registered nurses employed in Uruguay and 502 employed in Spain. We used multiple structural equation modelling analyses. The proposed model fit the data for both nursing samples. Burnout was found to fully mediate the relationship between work overload and turnover intention, whereas work engagement partially mediates the relationship between social support and turnover intention. The results contribute to our understanding of the potential applicability of two leading empirical models and of the dynamic relationship between work characteristics and turnover intentions through work engagement and burnout. Researchers should continue to focus on gaining a broader understanding of the effects of work characteristics in healthcare facilities and the associated organizational outcomes.
