The present study examined the role played by relational expectations in determining marital satisfaction and in discriminating between married couple types. The discrep ancy between one's expectations for his or her spouse's relntiorral behavior and one's perceptions of his or her spouse's actual behavior significantly predicted marital sutisfaction. Discrepancy scoresfor the relational dimensions of intimacy, distance, equality/ trust, dominance, and noncomposurelarousal appear to be most central in predicting satisfaction. While agreement between spouses on relational expectations significantly predicted satisfaction, expectationlperception discrepancies were reoealed to be stronger predictors than agreement scores. There were no dvferences in relational expectations when compared across couple type; however, intimacy and noncomposure/arousul displayed significant diflerences when compared across wives' individual marital type. Overall, intimacy, noncomposurdarousal, and equalityltrust played central roles in understanding marital satisfaction. U nderstanding marital functioning is an issue long pursued by researchers in communication and psychology. Evaluation of marital relationships has taken many forms based on various criteria for determining relational effectiveness. Probably the most frequently used criterion for assessing the functionality of marital relationships is the construct of satisfaction. The satisfaction experienced by each marital partner is considered by most theorists to be the best predictor of marital stability (Lewis & Spanier, 1979).
