Theory in Progress: Dyadic Power Theory: Constructing a Communication-Based Theory of Relational Power

Power is an integral part of any relationship, especially close familial relationships, because it determines how the partners relate to each other and how decisions are made. Rollins and Bahr's (1976) theory of power in marital relationships, referred to here as Dyadic Power Theory, is expanded to consider communication behavior, and to include other family dyads in addition to marriage. The theory, which emphasizes the dyadic nature of power, draws on past perspectives of power including those posited by social exchange theory, the chilling effect, sex roles, and normative resource theory. It is proposed that perceptions of legitimate authority to make decisions and access to a variety of resources increase individuals' perceptions of their own power compared to their partner. Perceptions of power, in turn, increase the likelihood of using dominant communication behavior in an attempt to control the interaction. Greater control attempts lead to greater influence over decisions. It is also predicted that perceptions of power will increase relational satisfaction for partners relatively equal in power. The propositional framework of dyadic power theory is explicated and suggestions for its use by family communication researchers are provided.
