The Role of Cognitive Flexibility, Visuospatial Working Memory and Impulsivity in Predicting Theory of Mind Deficit in Subjects with Borderline Personality Disorder Traits

Borderline personality disorder is a long-term pattern of abnormal behavior characterized by unstable relationships with other people, unstable sense of self, and unstable emotions. This study aimed to investigate the role of cognitive flexibility, visuospatial working memory and impulsivity in predicting theory of mind deficit in subjects with borderline personality disorder traits. The type of this study was correlational research. In this regard, 120 college students with Borderline personality traits were chosen by borderline personality inventory , and then participants were evaluated with Wisconsin Card Sorting Test, Barratt Impulsiveness Scale-11, Corsi Blocks Test and Reading the Mind in the Eyes Test. Data were analyzed using multiple regression. The results showed that visuospatial working memory and impulsivity predicts the theory of mind deficit in subjects with borderline personality disorder traits. Therefore, the results of this study indicated that subjects with borderline personality traits exhibited deficits in visuospatial working memory and impulsivity, and these variables predicts the theory of mind deficits in subjects with borderline personality disorder traits.
