Depression is one of the most common concerns that bring clients to treatment. Although marriage and family therapy has been shown to be an effective treatment, little research exists regarding the cost‐effectiveness of related services. In this study, we examined claims data for 164,667 individuals diagnosed with depression to determine (a) differences in the cost of treating depression according to type of therapy and license type, (b) differences in recidivism rates by age, gender, type of therapy, and type of mental health professional, and (c) differences in cost‐effectiveness by therapy modality and type of professional. The results showed that services provided by marriage and family therapists resulted in the lowest recidivism rate, and family therapy services were the least expensive.
