Theory-driven, evidence-based guidance on how to provide good quality CBT supervision has been lacking in the literature. Corrie and Lane have successfully filled this gap by producing a practically focused guide to CBT supervision, which encourages self-reflection and planning for supervisory practice. This is much less of a textbook, and much more of a toolkit or even a workbook, including reflective exercises for readers to complete and case study examples at the end of each chapter to enable readers to apply their reading to hypothetical (but highly plausible and familiar) supervisory dilemmas.

The book is divided into 4 sections, using the acronym “PURE”, where “P” stands for prepare, “U” stands for undertake, “R” for refine and “E” for enhance. Each section is divided into 3 chapters. The prepare section includes defining the kind of supervision that is offered, the context within which supervision takes place, and the negotiation of a contract for supervision. This leads into the undertake section, which encompasses the technical aspects of supervision delivery such as structuring sessions, choosing supervision interventions and evaluating supervisee competence. The refine section focuses on relational and process issues within supervision, including the development of the supervisory relationship, the management of power within it, and dealing with ruptures. Finally, the enhance section considers ethical issues in supervision, the evaluation of supervisory skills and competence, and a plan for increasing supervisory expertise.

This text has broad applicability, from those who are CBT supervisees (for whom the tips at the end of each chapter will be particularly helpful) to new CBT supervisors (who may wish to use the book as a step-by-step guide) and to experienced supervisors and trainers (who are most likely to dip in and out as needed). This is aided by the clear framework and structure for the chapters, conceptualized as a flower, enabling the reader to select the parts of the book that feel most helpful to them and their stage of learning about supervision. The text is supplemented by reflective exercises and case studies that are likely to suit a wide range of learning styles and preferences.

A real strength of this text is that it summarizes and draws on a number of non-modality specific models and frameworks for supervision practice, applying them specifically to CBT. It also places as much emphasis on process and relational issues as it does on technical prowess, which is refreshing for a CBT text. However, what it does not do, or indeed purport to do, is to thoroughly and systematically review all the literature in the area of supervision research. Overall, it is certainly a helpful addition to any supervisor or trainer's bookshelf.
