The measurement of perceived relationship quality components: A confirmatory factor analytic approach

This research tested three models of how the relationship evaluation components of satisfaction, commitment, intimacy, trust, passion, and love are structured and cognitively represented. Participants in Study I rated their intimate relationships on six previously developed scales that measured each construct and on a new inventory-the Perceived Relationship Quality Components (PRQC) Inventory. As predicted, confirmatory factor analysis revealed that, for both sets of scales, the best-fitting model was one in which the appropriate items loaded reliably on the six first-order factors, which in turn loaded reliably on one second-order factor reflecting overall perceived relationship quality. These results were replicated on a different sample in Study 2 and across sex. Implications and advantages of the PRQC Inventory are discussed.
