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 1 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.
