Abstract: (46 Views)
Narcissistic personality disorder and histrionic personality disorder are Cluster B personality disorders that, despite sharing certain behavioral traits, differ in their cognitive patterns. The present study aimed to compare cognitive errors and cognitive flexibility in individuals with narcissistic and histrionic personality disorders. A causal-comparative research design was employed. The statistical population consisted of clients at the Mersana Counseling Center in Tehran, from which individuals diagnosed with narcissistic and histrionic personality disorders were selected using simple random sampling. The Millon Clinical Multiaxial Inventory (MCMI-III) was used to diagnose personality disorders, while the Cognitive Distortions Questionnaire (Abdollahzadeh & Salar, 2010) and the Cognitive Flexibility Inventory (Dennis & Vander Wal, 2010) were used to assess cognitive errors and cognitive flexibility, respectively. Data were analyzed using an independent t-test. The results indicated no significant difference between the two groups regarding cognitive errors and cognitive flexibility. Regarding the components of cognitive errors, "magnification" ranked highest and "disqualifying the positive" ranked lowest in both groups. Additionally, scores for "jumping to conclusions" and "personalization" were higher in the histrionic personality disorder group compared to the narcissistic group. Overall, while no significant difference was observed between individuals with narcissistic and histrionic personality disorders regarding cognitive errors and cognitive flexibility, variations in specific cognitive error components may reflect distinct cognitive patterns associated with these disorders; recognizing these differences is essential for a more precise understanding and the design of interventions tailored to the specific characteristics of each disorder.
