Despite a call by researchers for estimates of the treatment clinical and cost effectiveness for relational problems, very little has been done to answer this call. The present study is an examination of actual treatment costs and recidivism rates for patients treated for a relational problem (either in individual or conjoint therapy sessions) in the CIGNA network. Despite the fact that this study compares treatment provider cost-effectiveness for treating relational problems, analyses do not control for average amounts paid by provider license type. Policymakers and third-party payers may use such clinical-effectiveness and cost-effectiveness data to make decisions regarding treatment of relational problems and funding allocation. The present study is also the first to compare the costs of couples therapy versus family therapy for relational problems.
