Affect, impulsivity, and metacognition in borderline personality disorder feature

The first aim of the present study is to examine the association of Borderline Personality Disorder feature (high-low), and positive affect (low-high) in two different dimensions of impulsivity namely self-report and delay-related. The second aim of the study is to explore effect of the gender on BPD feature. The last aim of the current study is to examine relationships among individuals' impulsivity scores (self-report and delay-related), and metacognitive abilities (monitoring action activity and dysfunctional metacognitive beliefs). The sample of the research consists of 236 (135 female and 101 male) participants whose ages ranged from 18 to 55. The participants firstly signed the informed consent, then completed the Demographic Information Questionnaire, Borderline Personality Inventory, Barratt Impulsiveness Scale-11, Delay Discounting Task (Monetary Choice Questionnaire), Metacognition Questionnaire-30, and Task-Related Metacognition Questionnaire. Results indicated that individuals who have high BPD feature also have higher self-report impulsivity scores than individuals with low Borderline Personality Disorder feature; individuals with low positive affect were found to have higher self-report impulsivity than individuals who are in a high positive affect state; individuals with high BPD feature and high positive affect made more impulsive choices than individuals with high BPD feature and low positive affect. Results regarding gender effect on Borderline Personality Disorder feature demonstrated that no significant difference in Borderline Personality Disorder feature in terms of gender. Also, it was found that increased delay-related impulsivity is associated with increased self-report impulsivity. Moreover, regarding metacognitive abilities, results showed that individuals who rate their decisions as more profitable during Delay Discounting Task tend to show less delay-related impulsiveness, similarly, they were found less impulsive in self-report measures. However, no association between dysfunctional metacognitive beliefs and monitoring action activity was found.
