Borderline personality disorder (BPD) represents a severe mental condition that is usually characterized by distressing identity disturbances. Although most prevailing explanatory models and psychotherapy approaches consider and intervene on self-concept, they seem not to recognize or explore idiosyncratic cognitive conflicts that patients may experience. These conflicts, which have been conceptualized as “implicative dilemmas” and “dilemmatic constructs” by personal construct theorists, could be considered as key elements of the explanatory model for BPD to provide a better understanding of this disorder and possibly enhance the effectiveness of contemporary psychotherapeutic approaches. The current study (Identifier: NCT04498104) aims to examine the characteristics of the interpersonal cognitive system of a group of patients diagnosed with BPD, using the repertory grid technique, and to compare them with those of a community sample. We will test if BPD participants are more affected by cognitive conflicts than controls. Additionally, we will gauge the association between cognitive conflicts and symptom severity as well as their predictive capacity of treatment outcome. The obtained results will be a necessary step to determine if cognitive conflicts have a substantial role on the explanation of BPD. It could also help to consider the development of a conflict resolution intervention module for this disorder.
