Self-other agreement was conceptualized as the degree of congruence between supervisors' self-assessment and subordinates' assessment of supervisors' transformational leadership. Data were collected from 36 supervisors and 189 of their subordinates. Statistical analyses revealed that self-other agreement on vision and individual support are positively associated with subordinates' perception of leader member exchange, and in turn leader member fully mediates the relationship between self-other agreement and subordinates' perceptions regarding their supervisors' performance. Additionally, results from polynomial analyses indicate that subordinates' ratings of LMX would be higher for in-agreement/good and underestimator supervisors, and would be lower for in-agreement/poor and overestimator supervisors. Some managerial implications are also discussed.enPeople Management & Leadership138444359081373095456
