This book offers a comprehensive presentation of person-centered individual psychotherapy. It describes and argues established positions while also raising questions for further research. The authors address topics that frequently arise in the general psychotherapeutic discussion but have received little or no attention in the person-centered context. The independence of person-centered psychotherapy is documented, and a distinction is made from other psychotherapeutic approaches. In the individual contributions, often provocative theses are initially formulated, which are then thoroughly justified and discussed in relation to existing literature, particularly the works of Carl Rogers. A detailed index of persons and subjects, as well as a bibliography, make this book an indispensable handbook – a new milestone in the field of person-centered psychotherapy. It covers the theory and practice of Rogers' concepts and their further development for various forms of counseling.
