Ciesielski, Roman (ed.) (2025). Psychotherapy Without Borders: Positive and Transcultural Psychotherapy Theory and Clinical Applications. Volume I. WAPP Press. 290 p. – ISBN 978-3910225565

This three-volume handbook offers a detailed journey through the entire scope of Positive and Transcultural Psychotherapy (PPT).
Volume I is dedicated entirely to theoretical issues, aiming to clarify the main concepts and fundamental assumptions of PPT. Here, readers will find discussions on the historical context of positive therapy, the core construct of positum—that which is real and actual, embracing both light and dark sides of human experience—and the profound justification for adopting a transcultural perspective. This volume also delves into the etiology of disorders, mechanisms of psychological change, and essential topics such as ethics in the profession of psychotherapy.
