Sense of Self: Its Place in Personality Disturbance, Psychopathology, and Normal Experience

Abstract

Sense of self (SOS) is a cornerstone of psychological inquiry and therapy and is a defining feature of a range of psychological conditions including borderline personality disorder, yet it is poorly understood. SOS is that continuous experience of being a complete and authentic person who feels in control of their own activities. It is a part of normal development of the self and, when weakened by trauma or developmental neglect, is a vulnerability for developing many different disorders, including depression and dissociative, personality, and eating disorders. This review aims to provide a working definition and description of SOS and to summarize its transdiagnostic role in contributing to psychological disorders. To achieve this aim, the article encompasses and unites the literature from various theoretical domains including developmental psychology, identity theory, cognitive psychology, personality disorders, and psychodynamic theories. Implications are raised for psychological therapy and research into psychopathology and its underpinnings.
