A theory of accommodation processes is advanced, and the results of 6 studies are reported. Accommodation refers to the willingness, when a partner has engaged in a potentially destructive act, to inhibit impulses to react destructively and instead react constructively. Studies 1 and 2 demonstrated that accommodation is lower under conditions of reduced social concern and lower interdependence. Studies 3, 4, and 5 revealed that accommodation is associated with greater satisfaction, commitment, investment size, centrality of relationship, psychological femininity, and partner perspective taking and with poorer quality alternatives. Commitment plays a fairly strong role in mediating willingness to accommodate. Study 6 showed that couple functioning is associated with greater joint and mutual tendencies to inhibit destructive reactions. Study 6 also demonstrated that self-reports of accommodation are related to relevant behavioral measures.
