Inquiry Based Stress Reduction is the name of the method which was developed by Byron Katie as ‘the Work’. Byron Katie is the author of very well-known self-help books. However, until now there was no manual available which explains the application of this method and the methodological and scientific evidence which can be given to support it. This book provides a comprehensive and exhaustive overview of how the method can be used by therapists in psychotherapeutic settings in mental health care, business coaches and coaches in other fields of life. As well as providing an extremely precise description of the working method for each step of the protocol, all these steps are clarified by means of practical examples and case studies. Target Group: psychologists, therapists and coaches.
