Interprofessional teamwork in primary care: the effect of functional heterogeneity on performance and the role of leadership.

This study aimed to unravel the complexity of interprofessional teamwork in primary care teams by testing the relationship between functional heterogeneity and team performance through the mediating role of information elaboration, and the moderating roles of directive leadership and participative leadership. The moderated mediation model was validated using survey data from 1105 professionals and 97 supervisors in 143 Dutch primary care teams. The results confirmed the model and showed a significant negative effect of functional heterogeneity on information elaboration, which in turn had a positive effect on team performance. Both directive and participative leadership moderated the negative effect of functional heterogeneity on information elaboration to the extent that the indirect negative effect of functional heterogeneity on team performance became insignificant under high levels of either directive or participative leadership. The theoretical implications of these findings for the literature on healthcare, team diversity, and leadership, as well as the practical implications for policy makers, educationalists and managers of primary care teams, are discussed.
