The role of individual personality in conceptualizing and measuring group characteristics

Abstract

In previous research, group characteristics have often been measured without taking the individual perspective of the group members into account. Therefore, the influence of individual personality (and other individual-level characteristics) on group characteristic ratings beyond the influence of the actual group remains largely unexplored. Additionally, some studies use group means of individual personality as group characteristics, however, evidence for interrelations or differences between these approaches has not yet been empirically based. In the present study, we employed a sample of 301 individuals from 54 teams, all of which rated both characteristics of themselves and their teams. By averaging both self-ratings and group-ratings within each team, we were able to compare both approaches to group characteristics and found them to likely measure unrelated constructs. We also found influences of individual Extraversion and Agreeableness from the HEXACO model on direct group characteristic ratings beyond the influence of the actual group. Years of work experience and work strain operationalized through burnout symptoms did not predict group characteristic ratings beyond the influence of the actual group and individual personality. Our findings imply that individual ratings of a group characteristic are influenced to a larger degree by the raters’ individual perspectives than by the presumed actual group characteristic itself. Further implications for research applying individual personality to groups are discussed.
