Social skill as moderator of the conscientiousness-performance relationship: Convergent results across four studies

The authors conducted 4 studies to test the hypothesis that the relationship between Conscientiousness and job performance reflecting interpersonal effectiveness is more strongly positive among workers who are higher rather than lower in social skill. Results of hierarchical moderated regression analyses supported the hypothesis in all 4 studies. Among workers high in social skill, Conscientiousness was positively related to performance. Among workers low in social skill, the relationship between Conscientiousness and performance was essentially irrelevant in Study 2 but was negative in the other 3 studies. Potential implications of these results are discussed as are directions for future research.
