The conversation therapy founded by Carl R. Rogers is a humanistic psychotherapy approach that is legally recognized in Germany, Austria, and Switzerland. The view of humanity in this form of therapy encompasses a fundamental trust in human resources and their development within relationships. Conversation therapy takes place in the relationship between therapist and client, when the client is able to experience and accept that the therapist understands them empathically and does not judge them in any way. This book provides a compact, professionally grounded overview of the effectiveness, practical approach, scientific validations, and areas of application of conversation therapy, illustrated by a case study.
