The new edition of this standard work on problem analysis and treatment planning provides an updated guide for the conception of cases in clinical and psychotherapeutic training and practice. The book provides guidance through the entire process of psychotherapy: selecting problems and establishing a diagnosis, analysing problems and behaviour at various levels, setting goals, creating motivation to achieve change, and selecting and evaluating therapeutic interventions within a framework of comprehensive treatment planning. This guide thus represents an outstanding aid for the orientation and structuring of an expert assessment report in the context of submitting applications for therapy. Selected working materials included in the book are available to readers for downloading.
