A Longitudinal Study of the Antecedents and Consequences of Collective Personality

In this study, we explored the development and relevance of collective personality to group effectiveness. To this end, we followed a sample of 94 newly formed groups over a 4-month period. First, the results showed support for the emergence of a Big Five structure of collective personality over time. This factor structure appeared to be well developed sometime between 2 and 3 months after group formation. Second, many group personality composition variables were significant antecedents of corresponding collective traits over time. Third, collective Conscientiousness, Agreeableness, and Emotional Stability predicted group task performance, group social loafing, and group task conflict, after controlling for group personality composition and group ability composition. These findings highlight the potential usefulness of collective personality traits in understanding group outcomes.
