Abstract

Relationship power, which refers to the ability to influence one’s romantic partner, is an important organizing principle in the assessment and treatment of couples. Power imbalance is predictive of various dimensions of marital quality, which explains why it is often a central focus of couple therapy. Despite the importance of relationship power in couple therapy, assessing power in clinical settings has been hindered by the lack of a validated measure of power that has high clinical utility. Data from 640 married couples associated with the Flourishing Families Project were used to develop the Perceived Power Imbalance Scale by conducting exploratory factor analysis, confirmatory factor analysis, dyadic predictive validity analysis, and measurement equivalence analysis. Although power has been conceptualized as consisting of both outcome power and process power, results indicated that the final scale consisted of four items that only tapped aspects of process power. The scale demonstrated good reliability and was a significant predictor of marital quality, marital instability, and depression.
