The purpose of this study was to compare outcomes for patients with Bipolar Disorder or Major Depressive Disorder based on severity of diagnosis. This study also compared psychotherapy providers and therapy modalities on total cost, number of sessions, and dropout. Our data set (N=136,439) came from Cigna, a national health care company. Results showed significant differences by severity of diagnosis. The comparison of providers showed that psychologists had higher costs and session numbers, while the other providers were not significantly different. However, all providers successfully provided low cost treatment on both MDD and BD. There is no support for the idea that one profession is more successful at providing low cost treatment for MDD and BD. Family therapy did significantly better on all outcomes except dropout rate when compared to individual or mixed (individual and family sessions) therapy. It is a low-cost option when treating MDD and BD, regardless of severity.
