Much relationship counselling today is conducted by generalist psychologists, social workers, and counsellors. Yet there is a strong case for a greater role for clinical psychologists. Accurate assessment during couples therapy is essential, the dynamics between people are complex, and the process is potentially very demanding of clinical skills. This book provides an opportunity to make the argument for greater involvement in relationship counselling by the clinical psychology profession and to guide both clinical students and practitioners toward an informed and integrated approach to relationship counselling, drawing on the best evidence-based treatments.
