Abstract: | The theories of exchange and of collective action were used to guide a study of the sources of satisfaction of the participants in a medical specialty society. This survey of two groups of participants, leaders and members, showed that the leaders of this nationally recognized professional association were more satisfied than were the regular members; that even though leaders and members have similar professional interests, the two groups evaluated the association differently; and that the involvement of leaders in the activities of other professional associations affected their satisfaction with this association. These results indicate empirical support for exchange theory and for the distinction among kinds of rewards made by the theory of collective action. Structural sources of satisfaction and dissatisfaction are identified for future research. |
