Findings on the theory of mind (ToM) abilities in borderline personality disorder (BPD) have been inconsistent. Surprisingly, no studies have focused on the complex aspects of ToM while simultaneously measuring alexithymia as well as comorbid depressive and anxiety symptoms, therefore, our study aimed to fill this gap. 30 female patients with BPD and 38 healthy controls (HCs) completed the Faux Pas Test (FPT) and the Toronto Alexithymia Scale-20 (TAS-20). The clinical and intellectual assessment comprised of the Structured Clinical Interview for DSM-IV-TR Axis II Disorders (SCID-II), the Borderline Personality Inventory (BPI), the State Trait Anxiety Inventory (STAI), the Center for Epidemiologic Studies Depression Scale Revised (CESD-R), and the Raven's Progressive Matrices (RPM). Women with BPD scored significantly worse than HCs on overall ToM abilities. After controlling for the intelligence level, depressive symptoms, and state and trait anxiety, both groups presented a similar overall level of alexithymia. No correlation between the FPT and TAS-20 scores was found, suggesting that both constructs might be unrelated in BPD. Because ToM dysfunctions seem not to result from comorbid clinical symptoms, trait anxiety, or intellectual abilities, our study results suggest that ToM deficits might be considered a core feature of BPD.
