James F. Masterson

James F. Masterson was a psychiatrist and author who developed a self and object relations approach to personality disorders. Psychotherapy of the Borderline Adult: A Developmental Approach sets out the framework through adult treatment, linking symptoms with developmental tasks and the therapeutic relationship. Treatment of the Borderline Adolescent: A Developmental Approach adapts it to adolescence and gives family dynamics a visible place.

From Borderline Adolescent to Functioning Adult: The Test of Time follows the longer course of treatment and asks what durable change looks like. Disorders of the Self: New Therapeutic Horizons: The Masterson Approach broadens the discussion across personality structures, while Psychiatric Dilemma of Adolescence returns to the pressures of that life stage. Psychotherapy of the Borderline Adult provides the firmest foundation; the follow-up volume then tests the model against time and outcome.
