How do the good become great? Practice From musicians and executives to physicians and drivers, aspiring professionals rely on deliberate practice to attain expertise. Recently, researchers have explored how psychotherapists can use the same processes to enhance the effectiveness of psychotherapy supervision for career-long professional development. Based on this empirical research, this edited volume brings together leading supervisors and researchers to explore a model for supervision based on behavioral rehearsal with continuous corrective feedback. Demonstrating how this model complements and enhances a traditional, theory-based approach, the authors explore practical methods that readers can use to improve the effectiveness of their own psychotherapy training and supervision. This book is the 2018 Winner of the American Psychological Association Supervision & Training Section's Outstanding Publication of the Year Award.
