Research has shown that people reduce their use of health care after individual psychotherapy. However, little research has been done to learn if marital and family therapy has a similar effect. Subjects (n = 292) from a health-maintenance organization were randomly selected according to the type of therapy they had received. Subjects' medical records were examined for 6 months before, during, and after therapy. Those who received marital and family therapy significantly reduced their use of health care services by 21.5%. These results show an “offset effect” for marriage and family therapy.
