Possible selves and borderline personality disorder

Although clinical theories suggest that people with Borderline Personality Disorder (BPD) experience a confused sense of self, little empirical research has directly examined the self in BPD (Heard & Linehan, 1993; Westen & Cohen, 1993). In this study, 43 female participants, 15 with BPD and 28 without BPD, completed the closed‐ended version of Markus and Wurf's (1987) Possible Selves Questionnaire (PSQ). Participants with BPD were less likely than controls to endorse positive possible selves as current, but more likely to endorse negative possible selves as current, probable, desired, and important. Participants with BPD linked negative and positive selves to their desired selves, which is consistent with the unstable sense of self characteristic of BPD. © 2005 Wiley Periodicals, Inc.
