Mindreading and metacognition patterns in patients with borderline personality disorder: experimental study

AbstractCurrent psychopathology attempts to understand personality disorders in relation to deficits in higher cognition such as mindreading and metacognition. Deficits in mindreading are usually related to limitations in or a complete lack of the capacity to understand and attribute mental states to others, while impairments in metacognition concern dysfunctional control and monitoring of one ’s own processes. The present study investigated dysfunctional higher cognition in the population of patients with borderline personality disorder (BPD) by analyzing the accuracy of metacognitive judgments in a mindreading task [reading the mind in the eyes Test (RMET)] and a subsequent metacogni tive task based on self-report scales: a confidence rating scale (CR) versus a post-decision wagering scale (PDW). It turned out that people from the BPD group scored lower in the RMET. However, both groups had the same levels of confidence on the PDW scale when giving incorrect answers in the RMET test. As initially hypothesized, individuals with BPD overestimated their confidence in incorrect answers, regardless of the type of metacognitive scales used. The present findings indicate that BPD individuals show dysfunctional patterns between instances of mindreading and metacognition.
