In an effort to inform empowerment theory and research, this paper provides a structural conception of power. First, we examine the essential features present in three dominant conceptions of power in community psychology: social power, psychopolitical power, and relational power. Next, commonalities in the key features of power identified by these conceptions are explored and pared down to yield a more parsimonious conception of power that is grounded only in the structural pattern of relationships through which resources are exchanged. Drawing on social exchange theory, we offer a method for measuring this streamlined, structural conception of power that allows for its more precise examination. Finally, we discuss the implications of a structural conception and measurement of power for targeting and facilitating empowering processes and evaluating empowered outcomes.
