Self-disclosure is a method of relationship maintenance, aiming to keep partners satisfied with their relationship. Partners learn a shared communication system, and disclosures are a large part of building that system, which has been found to be very beneficial in highly satisfying relationships. Significant positive relationships have been found between multiple measures of relationship satisfaction and the levels of spouses' disclosure on the Social Penetration Scale. Further, affection and support are provided to most in the most important ways through marriage. Surveys done by a variety of researchers have found that people list marriage as the ultimate form of intimacy. Spouses feel responsible, in that they need to be responsive to their partners' self-disclosures, more so than they feel obligated to respond to the disclosures of people in their other relationships.
