| Abstract: | Four studies examined the dimensions of relationship quality. In Study 1, based on a principal components analysis, four dimensions underlying the prototype of relationship quality were identified: intimacy, agreement, independence, and sexuality. The four–factorial structure was replicated both with a German sample (Study 2) and a Canadian sample (Study 3). Study 4 tested the validity of scales based on the four–factorial structure of relationship quality with German and Canadian samples. Relationship satisfaction was predicted well by the four scales, with intimacy contributing most, and sexuality least, to overall relationship satisfaction. The four scales correlated as predicted with other constructs relevant to close relationships, such as commitment, trust, love, and the like. Consequences for the measurement of relationship quality are discussed. |
