This article presents an empirical validation of the construct of team work engagement. Two different samples were used to test the hypotheses. Results from convergent and discriminant validity are presented as well as confirmatory factor analysis that explores the construct’s factor structure. Results support the idea that team- and individual-level work engagement are two different, yet related, constructs. However, data do not support the factorial invariance across levels: At the team level, the 1-factor structure, and not the 3-factor one, seems to be the one that best fits the data. This is a necessary first step for future research providing a justification for further analyzing the importance of team work engagement and its relationship with other variables, namely with team effectiveness.
