This is an important and thought-provoking book that carries the field of psychotherapy process research to a whole new level of reflection about practice and training. It will help students, practitioners, and researchers confronting them to the challenge inherent to the relationship-based activity of therapy. Beyond the usual therapeutic theories about patients, this book focuses on 'How does the mind of the therapist works while practicing therapy?' With diligence and passion, Fabienne Kuenzli invites us into the therapeutic room. She helps us to understand (with our cognitive intelligence) and to feel (with our perceptions and emotions) the concept of reflexivity as a central process for a successful therapeutic work.
