Sperry and Carlson's work, "How Master Therapists Work," explores the process of psychotherapy by analyzing a successful six-session therapy. The authors emphasize the importance of the therapist-client relationship and the therapist's contribution to creating change. The book features verbatim transcripts of therapy sessions, which are then reviewed by both authors, two master therapists, from the perspective of the therapist and a researcher. The commentary examines the therapist's inner thinking and connects therapy research to specific session moments. It serves as a guide for therapists of all experience levels who are interested in increasing their clinical proficiency and ability to support lasting positive changes in their clients.
