Process-based therapy (PBT) is an approach to psychological assessment and treatment centered on processes of change in particular people in their unique context. A flexible framework, the PBT model allows for any practitioner of evidence-based therapy like CBT or ACT to use PBT to conceptualize clients and inform treatment planning and decisions, while retaining their own orientation's language and techniques. A Process-Based Approach to Psychotherapy: Principles for Practice provides a practical foundation for clinicians, including graduate students, who are interested in learning how to deliver PBT. The book teaches readers how to, within a process-based model, develop a functional case conceptualization, assess client progress throughout treatment, and plan and adjust treatment in response to how a client is doing. Avoiding in-depth discussion of theoretical concepts, the authors instead provide practical principles and actionable steps for doing PBT, including case examples and exercises to facilitate a structured learning experience. Readers will come away with fundamental understanding of PBT that will allow them to immediately begin incorporating the model into their own practice.
