"Cauffman and Weggeman propose a way to extend the solution-focused approach into the field of applied psychology. They call their approach a Solution-focused Applied Psychology Protocol (SoFAP-P) by using a scientific innovation called Design Science Research as a methodology to ground their practice. Their conceptualization and presentation of SoFAP-P is true to the assumptions, spirit, and practices of the approach’s founders, Steve de Shazer, Insoo Kim Berg, and their colleagues at the Brief Family Therapy Center in Milwaukee, Wisconsin, U.S.A. Practitioners, researchers, and theorists alike will find much to admire and use in this clearly written, lively, and engaging book."Dr. Peter De Jong, PhD, M.S.W. , Calvin University, USA "By developing a scientific basis for a psychological treatment – the SoFAP-P design – they have played a pioneering role in the application of DSR to the field of applied psychology. As a co-developer of DSR, I hope this book stimulates further innovative developments to bring DSR methodology to the field of psychology."Dr. Joan van Aken, Eindhoven University of Technology, Netherlands.
