Personality Disorder (PD) is one of the most difficult psychological conditions to classify and treat and in the past literature on the subject has tended to neglect the invaluable viewpoint of sufferers themselves. Drawing on extensive research carried out in conjunction with service users, Heather Castillo seeks to adjust this imbalance and looks at the classification and treatment of PD from the service users' viewpoint. This book emphasises the need for health professionals to reassess their approach to the condition and allows those with PD to effectively define themselves and their illness. With a wide range of case study material and analysis, this book is essential reading for mental health professionals, workers in the voluntary and forensic sectors and service users themselves.
