This undergraduate introductory textbook provides a credible European alternative to the long-established US texts in the field. The book is divided into two sections. The first critically examines a number of general issues, including concepts of abnormality, diagnostic systems frequently used to classify mental health disorders and their alternatives, and psychological, biological and social factors that contribute to the development of disorders. It considers a number of approaches to the prevention and treatment of mental health disorders including cognitive behaviour therapy and psychoanalysis as well as more biological treatments. The second section considers the causes and treatment of a variety of disorders including schizophrenia, depression, sexual problems, anxiety and personality disorders. Each is viewed from psychological, social, and biological perspectives and different intervention types are investigated.
