"Basseches and Mascolo provide us the closest thing we have to a ‘unified field theory’ for psychotherapy. Breaking new ground for practitioners and researchers alike, the authors create a common lens and language to look across therapy’s many forms and to engage the central question for the growth of the field - not just whether a given practice is or is not successful, but why it is, and what the practitioner can do if it is not." - Robert Kegan, Meehan Professor of Adult Learning and Professional Development, Harvard University Graduate School of Education, USA

"This book is one of the most provocative and invigorating books on psychotherapy that I have read in recent years. In suggesting very novel ways to reflect critically and systematically on the theory, research, practice, and supervision of psychotherapy, the authors open new doors of immense value for the field of psychotherapy." - António Branco Vasco, Professor of Psychology, University of Lisbon, Portugal
"In this book, the authors argue that all forms of psychotherapy, regardless of theoretical underpinnings or therapeutic techniques, can be understood as processes of human development. Their DAPP Model is demonstrated with vivid case studies and detailed transcript analyses of psychotherapy sessions from a range of therapeutic traditions." - Abigail Lipson, Director of the Bureau of Study Counsel, Harvard University, USA

"Basseches and Mascolo take on and accomplish a breath-taking array of goals regarding psychotherapy practice and research…Through clear thought, deep appreciation for what all therapists do, and constant attention to the concrete details of psychotherapy process, they offer a book that will deepen our understanding of our own and others’ work, whether we’re practitioners or researchers, seasoned or beginners." - Suzanne Benack, Professor of Psychology, Union College, USA
