| Introduction: Patients with borderline personality disorder (BPD) suffer from a higher degree of
impulsive and hostile behavior, compared with other psychiatric disorders. On the other hand,
the impulsive behavior in these patients is different from the patients with type II bipolar
disorder (BMD II). This study aimed to investigate the differences between patients with BPD
and patients with bipolar disorder in the aggressiveness and impulsivity scales.
Methods: A descriptive-analytical study through a convenience sampling method was conducted on
117 patients with BPD (30 patients) and BMD II (87 patients) who completed the Buss and Perry’s
Aggression Questionnaire as well as the Barratt Impulsiveness Scale. The obtained data was analyzed
in SPSS using Student’s t-test, and its results were considered significant at P < 0.05 level.
Results: The two groups were significantly different in terms of attention and cognitive
complexity of Barratt Impulsiveness Scales, hostility, and physical aggression. In addition, they
significantly differed in terms of the total score of Buss and Perry’s Aggression and Hostility
Questionnaire. The scores of patients with BMD in the above-mentioned scales were higher
compared with the BPD. Moreover, the marital status variable was significantly correlated with
age, physical aggression, anger, anxiety, cognitive complexity, and perseverance.
Conclusion: The patients with BMD II experienced a higher degree of excitement in terms of
hostility, violence and impulsivity measures; it is also different from the patients with borderline
disorder in terms of type of aggressiveness. |
