One of the principal formulations of borderline personality disorder is based on object relations theory, a component of psychoanalytic theory. To remain relevant, psychoanalytic formulations must find support from empirical research. After summarizing the object relations understanding of borderline personality, the authors review studies in biological neuroscience, developmental psychology and cognitive science related to the fundamental concepts of object relations theory as it aplies to borderline pathology. This review suggests that these empirical studies support psychoanalytic formulations originally derived from clinical practice and observation.
