Personality Characteristics and Development of Psychopathology in Bipolar I and Borderline Personality Disorder Patients

The debate whether Bipolar Affective Disorder and Borderline Personality Disorder fall under the same spectrum or they represent separate categories has received much research attention. However, the question of their underlying psychological aetiology as well as their personality correlates has remained largely un-explored. The present study aims at gaining knowledge about and insights into these questions. The sample studied consists of 10 Bipolar I patients and 10 patients with Borderline Personality Disorder. Following a cross-sectional design, after determining the remitted phase of Bipolar I patients using Hamilton Depression Rating Scale and Young’s Mania Rating Scale, the Temperament and Character Inventory, Attachment Style Questionnaire, Defense Style Questionnaire and Rorschach Inkblot Test were administered individually by the researcher. Both group of patients showed features of immaturity and instability. A correlational analysis indicated the probable pathway of development of psychopathology. The parallels of the findings to Kernberg’s concept of borderline personality organization have been discussed.
