Traditionally, people with psychotic symptoms have been treated with anti-psychotic or neuroleptic drugs. While this approach is beneficial to a number of people, there are many for whom it is problematic. Recent recognition of these problems has led to the development of effective complementary treatments of a specifically psychological nature. In this text, leading researchers and practitioners in this area provide a comprehensive overview for all those undergoing related training in psychology and psychiatry, as well as nursing and social work. The book provides a general background to cognitive treatment, and also discusses specific uses of the therapy in treating those who have hallucinations, as well as those with delusions and schizophrenia. The contributors also suggest how cognitive behavioural approaches can be integrated with other strategies such as pharmacological methods, or in the context of the family.
