Abstract
This research coded 40 leaders’ communication and used 172 subordinates’ questionnaires to analyze the relationship of leader communication behavior to commitment. A hierarchical multiple regression was performed for two types of organizations. At hospitals, leaders’ consideration style and reinforcement related positively to subordinate commitment, while interruption and humor related negatively. At a city government, initiating structure style and professionalism related positively to commitment; reinforcement and interruption related negatively.
