PurposeThe purpose of this paper is to examine the mediating role of work engagement (vigor and dedication) between job resources (job characteristics, supervisor and co-worker support, participation in decision making and job security) and job performance (task and contextual) rated by the supervisor.Design/Methodology/ApproachA sample of 364 nurses and their supervisors was used. Structural equation modeling with Amos 17 was used to obtain a model fit with path significance of work engagement as the mediator between job resources and job performance.FindingsThe results found support for the proposed conceptual claim and confirm that work engagement with a two-factor model (vigor and dedication) mediates the relationship between job resources (job characteristics, supervisor and co-worker support, participation in decision making and job security) and with a multidimensional construct of job performance (task and contextual performance) rated by the supervisor.Practical ImplicationsThe findings of this research will help human resource managers and professionals to further develop the working environment, provide job security and opportunities for employees to participate in decision making in a way that enhances employee work engagement, which, ultimately, improves employee job performance.Originality/ValuePast studies have not previously tested the two-factor model of work engagement (vigor and dedication) as the mediating variable between job resources (job characteristics, supervisor and co-worker support, participation in decision making and job security) and job performance rated by the supervisor.
