Book excerpt: What is it that makes some therapists so much more effective than others, even when they are delivering the same evidence-based treatment? This instructive book identifies specific interpersonal skills and attitudes--often overlooked in clinical training--that facilitate better client outcomes across a broad range of treatment methods and contexts. Reviewing 70 years of psychotherapy research, the preeminent authors show that empathy, acceptance, warmth, focus, and other characteristics of effective therapists are both measurable and teachable. Richly illustrated with annotated sample dialogues, the book gives practitioners and students a blueprint for learning, practicing, and self-monitoring these crucial clinical skills.
