Abstract

This review examines relationships between group personality composition (GPC) and group effectiveness, focusing on four questions: (a) How have researchers operationalized GPC? (b) What criteria have been used as measures of group effectiveness? (c) Is GPC related to group effectiveness? (d) Under what conditions is GPC associated with group effectiveness? A review of 31 studies yielding 334 unique relationships distinguished task and relationship predictors and criteria. Findings indicate operational definitions of GPC are varied, variance scores correlate negatively with group effectiveness, and minimum scores predict as well as mean scores. GPC is related to group effectiveness, and the effect is stronger in field studies than lab studies. Implications are discussed.
