We intend to use the information collected from the proposed investigation to refine and modify BCT to enhance its positive effects on children. This process of (a) examining multiple dimensions of functioning and (b) evaluating theoretically and empirically identified mediators and moderators to inform intervention development and refinement has been used successfully for over a decade with BCT, resulting in empirically informed BCT variants for alcoholic patients, drug-abusing patients, patients who engage in domestic violence, female substance-abusing patients, and so on. Thus, this project provides the next critical step for BCT refinement and interventions for couples entering BCT who have custodial children, the latter of whom we may only be able to help by helping their parents.
