In Learning Process‑Based Therapy: A Skills Training Manual for Targeting the Core Processes of Psychological Change in Clinical Practice, Stefan G. Hofmann, Steven C. Hayes & David N. Lorscheid propose a paradigm shift away from standardised protocol‑based therapies toward a flexible, process‑based approach that focuses on the specific psychological mechanisms driving change. The authors argue that many established therapies target syndromes rather than the processes that underlie human suffering, and they offer a framework for identifying and intervening on core processes such as cognition, affect, attention, self, motivation and overt behaviour.

The manual is practical and clinician‑friendly: it provides detailed worksheets, case examples, and tables to help therapists apply process‑based therapy (PBT) in real‑world settings, enabling personalised treatment plans and integration across therapeutic modalities. Whether the practitioner uses cognitive behavioural therapy, acceptance and commitment therapy or another model, this book gives the tools to shift toward a process‑driven, client‑centred practice that enhances therapeutic flexibility and outcomes¹.
