This paper offers a brief overview of the historically predominant form of psychotherapy research both for individual and group psychotherapies, the randomized control trial (RCT), and its surrounding controversies and critiques as the backdrop from which new directions in both clinical theory building and research are being pursued, including efforts at building integrative models of treatment. The paper explores one promising integrative model, namely the incorporation of process and dynamic orientations into the province of group cognitive behavioral therapy (CBT) and identifies challenges in implementing this model.
