Assessment of Sense of Identity in Patients Diagnosed With Borderline Personality Disorder. A Pilot Study

Assessment of Sense of Identity in Patients With a Diagnosis of Borderline Personality Disorder Through Autobiographical Memory and the Contents of Self-defining Memories, Compared to a Group of Healthy Individuals. A Pilot Study

One of the key features and long considered a fundamental element of Borderline Personality Disorder is the disruption of identity. Autobiographical memory is closely linked to the development and maintenance of a coherent, stable sense of self. It enables the individual to understand who he or she is. The investigators hypothesize that individuals diagnosed with Borderline Personality Disorder have a less coherent, stable sense of the self than healthy controls. The aim of the study is therefore to compare the sense of identity between a group of patients diagnosed with Borderline Personality Disorder and a group of healthy individuals (without Borderline Personality Disorder ).

This can be measured by evaluating the content of the self-defining memory using the Self-Defining Memory scale.
