The role of interpersonal cognitive distortions, differentiation of self and interpersonal problems in predicting the organization of borderline personality in undergraduate student

Borderline personality disorder is characterized by features such as identity diffusion, primitive defense mechanisms, fear of intimacy, and reality-testing deficiencies. The purpose of this study was to investigate the role of components of interpersonal cognitive distortions, differentiation of self and interpersonal problems in predicting of borderline personality. For data analysis, stepwise multiple regression analysis was used. 318 undergraduate students were selected by random cluster sampling and filled the Interpersonal Cognitive Distortions (Hamamci & Büyüköztürk, 2004), Differentiation of Self (Skowron & Friedlander, 1998), Interpersonal Problems (Barkham, Hardy & Startup, 1994), and Borderline Personality Scale (Leichsenring, 1999). The results of stepwise regression analysis showed that among the components of cognitive distortions, the expectation of rejection (R2= 0.20), among the components of differentiation, emotional cutoff (R2=0.34), and among The components of interpersonal problems, aggression (R2=0/15), had the most role in explaining the borderline personality (p< 0/01), which in this study were presented as " triad spacing mechanism " in the borderline personality. Also in borderline personality organization in the component of identity diffusion, cut-off (R2=0/21) in defense mechanisms, reactivity (R2=0/22), in fear of intimacy, cut-off (R2=0/34) and in reality testing, misperception (R2=0/23), had a greater role in explanation (p< 0/01). Considering these dimensions can be useful in redefining borderline personality disorder as a distance personality in preventing and intervening in treatment.
