Cost-effectiveness of marital therapy was examined beginning with a simple question: If government or health insurers paid for the screening and, where indicated, empirically supported treatment of 100,000 randomly selected married persons (i.e., 50,000 couples) from the general population, would the financial benefits outweigh costs? Two empirically supported forms of marital therapy, behavioral marital therapy and emotionally focused therapy, were considered in aggregate as possible treatments of choice. Marital therapy appears to be cost-effective when paid for by government to reduce public costs of divorce or when paid for by insurers to offset the increased health-care expenses associated with divorce. Implications and specific needs for future research to substantiate these conclusions are discussed.
