The agreement between a leader's self-rating of leadership and ratings from the leader's subordinates, peers, and superiors (i.e., self-other agreement) is critical to understanding leadership, but questions remain regarding the extent to which leaders are aware of their behaviors. This meta-analysis investigates whether leader-observer agreement is influenced by type of observer and type of leadership. First, we examined the convergence (i.e., correlation) between leader- and observer-ratings along several dimensions of leadership (e.g., initiating structure, consideration, contingent reward, and transformational leadership). Our results indicated that leader-observer correlations were generally moderate and of similar magnitudes for task- and relation-oriented behaviors (with the exception of a strong correlation for contingent reward). Next, we compared leaders' and observers' mean-level ratings (i.e., Cohen's d), and found that leaders generally reported lower or similar levels of task-oriented behaviors but higher levels of relation-oriented behaviors. Last, several variables (e.g., sampling method and study purpose) moderated leader-observer convergence. Implications of these findings for research, theory, and practice are discussed.
