“…Dozens of studies in the psychology literature have demonstrated an offset effect, as the costs of psychotherapy are more than offset by decreases in medical service utilization after psychological treatment (for a review, see Chiles et al., 1999). While few studies in marital and family therapy (MFT) have addressed treatment effects this way, most of those that have support the use of couple‐ and family‐based treatment methods (Fals‐Stewart, O’Farrell, & Birchler, 1997; Finney, Riley, & Cataldo, 1991; Graves & Hastrup, 1981; Henggeler, Melton, & Smith, 1992; Law & Crane, 2000; O’Farrell et al., 1996; Kessler, Steinwachs, & Hankin, 1982, is an exception). In the most recent of these studies, clients receiving nonmanualized couple or family treatment experienced a decrease of more than 20% in medical service utilization in the 6 months following treatment, more than twice the percentage decrease found for clients receiving individual therapy (Law & Crane, 2000).…”
