Abstract
Survey data were collected from 127 subordinate-supervisor dyads employed in diverse organizational settings. Hierarchical regression analyses revealed that subordinate-supervisor conscientiousness similarity predicted subordinate in-role behavior. Also, subordinate in-role behavior closely approached significance as a predictor of higher quality leader-member exchanges (LMX), whereas LMX was correlated with subordinate organizational citizenship behavior and supervisor effectiveness. As a function of conscientiousness similarity, the observed relationships are explained in terns of improved subordinate-supervisor compatibility and reciprocity. Examples are provided.
