Borderline Personality Disorder: A Personal Construct Approach

Abstract

In 2003, Winter, Watson, Gillman-Smith, Gilbert and Acton criticised the DSM-IV’s psychiatric conceptualisation of BPD, proposing a set of alternative descriptions based on Kelly’s (1955) Personal Construct Psychology (PCP) and diagnostic constructs. According to Winter et al. (2003), PCP offers not only a less “pre-emptive” stance towards BPD but is more clinically useful given its intrinsic implications for treatment. This correlational research study aimed to determine whether BPD symptomatology is associated with these proposed characteristics of construing. In addition, it was hypothesised that those with a belief that BPD was a part of their identity and untreatable would display higher levels of hopelessness. Ten participants with an existing diagnosis of BPD completed the following measures: a) Personal Construct Inventory (PCI; Chambers & O’Day, 1984); b) Millon Clinical Multiaxial Inventory, Third Edition, (MCMI-III, Millon, 1994); and c) Beck Hopelessness Scale (BHS; Beck & Steer, 1988). Participants were also asked to complete a repertory grid and a Likert Scale indicating the extent of their belief that: a) BPD is an intrinsic part of them; and b) BPD is a treatable condition. Two of the participants are presented as case examples.

The most significant finding related to the hypothesis that greater BPD symptomatology would be associated with a higher degree of change in self-construction over time (‘slot-rattling’). Contrary to our prediction, similarity of construing of the elements ‘Me Now’ and ‘Me in the Past’ was correlated with greater BPD symptomatology. This may indicate a belief among participants that they are unable to change or may represent Kellian hostility. Construing one’s mother and father similarly to one’s therapist was associated with greater BPD symptomatology, as was construing one’s father and partner similarly, suggesting, as hypothesised, that those diagnosed with BPD tend to construe current relationships in the same terms as early relationships. Pre-emptive construing and poorly elaborated self-construction were also found to be associated with increased BPD symptoms as predicted. Content analyses performed on elicited constructs revealed that emotion regulation is the most salient area for participants. While the majority of participants considered that BPD was a part of their identity, most were uncertain as to whether BPD is treatable although these findings were not significantly correlated with levels of hopelessness. Participants’ feedback about their experiences of being diagnosed with BPD raises important ethical questions. Further hypotheses are generated based on the study findings and suggestions are made for a revision of the way in which psychological distress is conceptualized, with a particular emphasis on the utility of the PCP approach towards BPD. Clinical implications, limitations of the study and possibilities for further research are discussed.
