Testosterone-status mismatch lowers collective efficacy in groups: Evidence from a slope-as-predictor multilevel structural equation model

Abstract

The study of the biological underpinnings of behavior is in its nascent stages in the field of management. We study how the hormone testosterone (T) is related to status and collective efficacy in a group. We assessed salivary testosterone of 579 individuals in 92 teams. We find that T does not predict status within the group. We also tested the effects of a mismatch between T and status in the group on the collective efficacy of the group. Using a novel slope-as-predictor multilevel structural equation model, we find that the greater the mismatch between T and status in the group (i.e., the more negative the within-group correlation among T and status), the lower is the collective efficacy ..
