Clinical psychology remains one of the most popular and exciting fields of psychology. As mental disorders and issues in the population increase, the practical relevance of the discipline also grows. Hautzinger and Thies introduce the paradigms, assessment methods, interventions, and classification systems of clinical psychology in the foundational section. However, the focus of this concise textbook is on the disorders: the development, diagnosis, and treatment of the most important mental disorders are presented, including schizophrenia, affective disorders, anxiety and obsessive-compulsive disorders, personality disorders, and eating disorders. It also includes mental disorders in childhood and adolescence as well as in old age. The textbook presents the contents of clinical psychology in a brief and illustrative manner, with practical relevance through numerous case studies.
