| Abstract: | The leader–member exchange (LMX) literature is reviewed using meta-analysis. Relationships between LMX and its correlates are examined, as are issues related to the LMX construct, including measurement and leader–member agreement. Results suggest significant relationships between LMX and job performance, satisfaction with supervision, overall satisfaction, commitment, role conflict, role clarity, member competence, and turnover intentions. The relationship between LMX and actual turnover was not significant. Leader and member LMX perceptions were only moderately related. Partial support was found for measurement instrument and perspective (i.e., leader vs. member) as moderators of the relationships between LMX and its correlates. Meta-analysis showed that the LMX7 (7-item LMX) measure has the soundest psychometric properties of all instruments and that LMX is congruent with numerous empirical relationships associated with transformational leadership.
