This book draws on clinical research findings from the last three decades to offer a review of current psychological theories and therapeutic approaches to understanding and treating auditory hallucinations addressing key methodological issues that need to be considered in evaluating voice hearing interventions. 'I strongly recommend this book to researchers and practitioners interested in psychological approaches to distressing voices. The book describes key themes coming out of various psychological traditions and analyses the similarities and differences between them. In each chapter, the state-of-the-art is presented and gaps in our current knowledge are identified. Emphasis is put on the methodological issues that need to be considered in evaluating psychotherapeutic interventions. Thus, suggestions for future research are provided with the aim of developing more effective interventions for distressed voice-hearers. ...the book makes an excellent synthesis of "where we are now and where we are going". It helps to reflect critically on our current knowledge and opens many tracks for future research.' - Professor Lony Schiltz, Head of Research Unit in Clinical Psychology, Hôpital Kirchberg, Luxembourg, in Psychosis, 2015
