Exploration of the moderator effect of cultural diversity on team performance across 45 professional football leagues: An ecological dynamics perspective on cross-cultural research

Abstract

ObjectiveTo investigate the moderating effect of cultural diversity on team performance in professional football worldwide through the lens of ecological dynamics and cross-cultural psychology. Designand Method: Based a sample of 23,186 matches played by 728 teams across 45 leagues during the 2020/21 season, two sets of moderated regression analyses were conducted to examine the effect on sporting results of the interaction between teams’ cultural diversity, their dominant playing style and market value. In addition to bivariate correlations, a total of 16 ordinary least squares (OLS) regression models were designed to test 5 hypotheses. A new theoretical model, the Integrative Categorization-Intentionality Model (ICIM), was proposed to explain four key findings. FindingsCDI’s role as a statistically significant cross-cultural moderator was confirmed in relation to all three styles of play: possession-based (ß = −0.08, p < 0.05), constructive attacking (ß = −0.30, p < 0.01), and defensive (ß = 0.28, p < 0.05), the respective models explaining 35.6%, 34% and 35% of the variance. Results showed that cultural heterogeneity contributes to goal scoring in teams reliant on the first two styles, whilst defensively-oriented teams were more likely to improve performance with increasing cultural homogeneity. Moreover, the positive effect of cultural heterogeneity on sporting outcomes was more likely in less affluent teams. Finally, empirical evidence revealed a link between enhanced performance and a higher proportion of domestic defensive players in defensively oriented teams (ß = −0.11, p < 0.05), and, similarly, between a higher proportion of foreign offensive players in offensively-oriented teams (ß = −0.27, p < 0.01). ConclusionsThe study has practical implications for scouting/recruitment of players when strategizing on team cultural and functional composition, as well as for coaches in terms of designing suitable training practices gauged to match and develop multicultural teams’ diverse skill set, or more generally, in relation to managing multicultural teams.
