The field of psychotherapy has developed from different roots, and many clinicians and scientists still consider psychotherapy as a collection of unconnected groups of theories and associated interventions. This approach prevents a cohesive development of the discipline and a holistic treatment of patients. During the webinar, Professor Stefan G. Hofmann from the Philipps-University Marburg, Germany and Boston University, USA will talk about process-based psychotherapy, which takes the view that mental health problems are assumed to exist as systems of inter-connected elements.
