This paper proposes a metatheory of work motivation incorporating theories
of self-concept that have been proposed in the sociological and psychologic
al literatures. Traditional theories of work motivation are reviewed, and t
he self-concept-based sources of motivation are presented. How the self-con
cept influences behavior in organizations is explained and used to develop
a metatheory of motivational sources. Both research and managerial implicat
ions of the model are presented.
