title: Further validation of the interpersonal exchange model of sexual satisfaction.
abstract: We conducted two studies to further test the validity of the Interpersonal Exchange Model of Sexual Satisfaction for long-term opposite-sex relationships (IEMSS; Lawrance & Byers, 1995). Study 1 examined, in a sample of 79 individuals, the extent to which the history of sexual exchanges is associated with sexual satisfaction as well as whether changes in sexual rewards and costs are associated with change in sexual satisfaction. Using a sample of 104 couples, Study 2 examined whether partner rewards and costs add to individuals' own sexual satisfaction over and above own sexual rewards and costs for men or women. The results provided further evidence for the validity of the IEMSS, including support for the propositions that in long-term relationships: (a) sexual satisfaction is influenced by the history of sexual rewards and costs rather than by rewards and costs at a particular point in time; (b) decreases in sexual satisfaction are associated with sexual exchanges becoming less favorable; and (c) satisfaction is influenced by dyadic factors for both men and women.
