Formulating cases is an essential component of psychotherapy training and practice. Yet beginning therapists often struggle to organize their ideas about the client and apply theory to the case. Psychotherapy Case Formulation is based on the author's extensive experience teaching case formulation to graduate students. It describes a highly adaptable and evidence-based framework for conceptualizing clients and planning treatment. Applicable to both simple and complex cases, the model can be used regardless of one's theoretical orientation. Readers are introduced to basic concepts that include the benefits of case formulation, sound decision-making, and the importance of cultural considerations, and then are led step-by-step through the action-oriented components of the model. This book is an indispensable aid for novice and experienced therapists seeking to develop and improve upon this core competency.
