This study investigates the mediating role of work engagement (i.e. vigour and
dedication) among job resources (i.e. job control, feedback and variety) and proactive
behaviour at work. This mediating role was investigated, using Structural Equation
Modelling in two independent samples from Spain (n ¼ 386 technology employees)
and the Netherlands (n ¼ 338 telecom managers). Results in both samples confirmed
that work engagement fully mediates the impact of job resources on proactive
behaviour. Subsequent multigroup analyses revealed that the strengths of the structural
paths of the mediation model were invariant across both national samples, underscoring
the cross-national validity of the model
