Theodore Millon, one of the world's leading authorities on personality disorders and the best-selling author of Disorders of Personality, explores the many subtleties involved in diagnosing and treating these debilitating disorders. For each clinically-recognized class of personality disorders and its subtypes, Millon and his co-authors examine all current schools of thought--including the biological, psychodynamic, interpersonal, cognitive, and biopsychosocial models--on the factors that promote personality dysfunction. And they outline the most successful effective treatment approach for each disorder.
