Dr Masterson pioneered the developmental self and object relations approach (DSOR) to the psychotherapy of the Personality Disorders mainly through clinical research. He is one of the first clinicians to conduct empirical research on the borderline personality disorder more than three decades ago,long before empirical research was considered important. Dr Masterson was also the founding father of The Society of Adolescent Psychiatry and past president of its New York Chapter. The body of Dr. Masterson’s work is represented in the books he has written, many of which have been translated into several languages, including early work in the field of the real self, which represents a breakthrough in treatment of the borderline and narcissistic disorders.

His last book , “The Personality Disorders Through the Lense of Attachment Theory and Neurobiology Development of the Self,” just published by Zeig, Tucker, Theisen, is a choice of the Behavioral Science Book Service (see Club review at http://www.behavioralsciencebooks.com).
