Investigating work group characteristics and performance over time: A replication and cross-cultural extension

The authors tested a longitudinal work group model that focuses on the effects of several group characteristics on performance. One main objective was to replicate and extend D. Jung and J. J. Sosik's (1999) findings in both individualistic and collectivistic cultures. Results indicate that potency had a consistently positive relation to performance in the U.S. sample. This generalized to the Korean sample at Time 2. Performance at Time 1 had a positive relation to subsequent perceived homogeneity and outcome expectations for both samples. In the current study, preference for group work had no relation to group performance at Time 1; at Time 2, it was negatively related to performance among Koreans and positively among Americans.
