The mediating role of narcissistic and borderline personality disorder tendencies in the relationship between core beliefs of worthlessness and self-critical rumination

Summary/Abstract: As a new concept, self-critical rumination involves repetitive negative self-critical mind processes and has been explored by a limited number of studies. The present study aimed to examine the mediating role of narcissistic and borderline personality disorder tendencies in the relationship between negative core belief of worthlessness and self-critical rumination. The study was conducted with 597 participants aged 18 years and over, consisting of 498 females (83.4%), 97 males (16.2%), and 2 participants (0.03%) who chose the other option. Demographic Information Form, Self-Critical Rumination Scale, Negative Core Beliefs Scale, and Coolidge Axis II Plus Inventory were used in the study. SPSS Process Macro was used to examine the mediating roles of personality disorder tendencies in the relationship between core belief of worthlessness and self-critical rumination. The results yielded core belief of worthlessness, narcissistic, and borderline personality disorder tendencies were all positive predictors of self-critical rumination. Furthermore, the results revealed that both narcissistic and borderline personality tendencies significantly mediated the relationship between core belief of worthlessness and self-critical rumination. Regarding the results of the present study, it seemed necessary to work with the core belief of worthlessness and narcissistic and borderline personality disorder tendencies as well while working through self-critical rumination in psychotherapies as it is a critical burden for both the psychotherapeutic process and the outcomes.
