Background Borderline Personality Disorder (BPD) is considered to be one of the most debilitating and difficult to treat mental disorders. Traditionally, studies investigating the aetiology and mechanisms associated with the development and exacerbation of BPD have relied on the use of clinical populations. As a consequence, the opportunities to understand vulnerabilities and fundamental processes that may contribute to the development and maintenance of the disorder have been limited. Objectives The aim of this study was to examine the potential interactions and mediating effects of metacognition and emotion regulation on the relationships among different forms of childhood abuse, attachment, and parental bonding with a composite of core BPD features designed to encompass major areas of personality functioning and pathological personality traits (per DSM-5 section III). Method: A non-clinical sample of 695 students in the city of Edinburgh, Scotland took part in an internet survey composed of a battery of self-report measures. This was geared to identify features associated with BPD, emotion regulation difficulties, characteristics of metacognition, adult insecure attachment, fundamental parental bonding styles and signs of childhood maltreatment. Structural Equation Modelling (SEM) was used to analyse the data. Results All variables of interest had a direct effect on the development of features associated with BPD. Metacognition was found to mediate the effects of all three forms of childhood abuse used in the study as well as the effects of adult insecure attachment on the development BPD related traits. Emotion regulation suppression was found to mediate the effects of sexual and physical childhood abuse (but not emotional abuse, adult insecure attachment, parental bonding indifference, or parental bonding overprotection) on the development of borderline features. In addition, the lack of emotion regulation reappraisal was found to mediate the effects of sexual abuse and adult insecure attachment (but not emotional or physical abuse, parental bonding indifference, or parental bonding overprotection) on the development of BPD related traits. Discussion These findings have important clinical and theoretical implications. The results provide support and understanding of the role of mediating mechanisms in the exacerbation and in the development of features associated with BPD. This is important because metacognition and emotion regulation may be more amenable to change than traumatic past experiences and/or deep seeded patterns of attachment. In addition, further development in this area of research has the potential to lead to better and more effective psychotherapeutic treatments for BPD.

Borderline Personality Disorder (BPD) is among the most troubling Personality Disorders. Individuals with the disorder have exaggerated fears of abandonment, distorted self-identity and problems in interpersonal relationships, and are prone to self-abuse, suicide ideation and attempts, rage and aggression. Furthermore, these individuals have an exceptional aversion to admitting that these problematic behaviours are symptomatic of an underlying disorder, and therefore in accepting responsibility for their behaviour. Using a Spinozist approach, I analyze that we the public share in the responsibility for having a population with BPD. Under the guidance of Hasana Sharp’s Politics of Renaturalization, I argue that the individual with BPD resists accepting responsibility because she is not completely to blame. Spinoza’s radically relational ontology shows that no individual can act without affecting and having been affected by the myriad of other beings, especially other humans. We the public share in the blame for having a population with BPD, and I argue that admitting so will help the individuals with BPD gain self-knowledge and accept their respective share of the responsibility for these problematic behaviours. This will serve the best interests of the public by affording more credence and adding new voices from these personalities in collective conversation

Eating disorders and borderline personality disorder involve several overlapping features, such as impulsivity, negative affectivity, and dissociation. However, few studies have specifically assessed how eating pathology and borderline personality may be related. The present study sought to evaluate this relationship by focusing on one particular area of overlap, negative affectivity. A pilot study assessed the psychometric properties of a dietary restraint measure among undergraduate women (N = 149). In the main study, undergraduate women (N = 307) completed a baseline mood assessment, then viewed a 39-minute sad film either with or without concurrent food presentation. Participants then completed a second mood assessment, and those who received food completed a third mood assessment following a 10-minute post-reflection delay. Results suggest that women reporting more borderline features exhibited greater negative affect across three different time points (baseline, post-movie/food, and post-reflection period), and were more reactive to the sad film. Food presentation appeared to have a small tempering effect on sadness, such that individuals who received food reported relatively less sadness after viewing the film when compared to those who did not receive food. However, actual quantity of food consumption was associated with improvements in mood only for women reporting higher levels of borderline features. Finally, highscorers on dietary restraint measures consumed greater quantities of food than their lowscoring counterparts. In sum, these data suggest that women with borderline personality features may be at elevated risk for developing problems with binge-eating, as consuming larger quantities of food appeared to have a tempering effect on their negative mood and specific feelings of sadness. Further, results are consistent with earlier findings in that reported efforts to restrain dietary intake were associated with greater food consumption in response to negative affect, and this relationship may need to be addressed in treating individuals with problematic eating behaviors.

Depression and borderline personality disorder (BPD) are highly comorbid and are both characteristic of affective disturbance. In this study, it is hypothesized that the disorders share a common etiological factor of emotion reactivity. In addition, an investigation of specific emotional experiences that may differentiate the two symptom clusters is undertaken. A mood induction task was used to elicit emotional reactions in a sample of 121 university students. Regression analyses were conducted to examine emotion reactivity as a common factor. Unique associations between specific emotions and features of BPD, depression, and an interaction term (BPDxDep) were investigated. It was found that all models tested were significant, with the exception of joy. Features of BPD were uniquely associated with sadness, guilt, and anger, as were depressive features. BPDxDep symptoms were negatively associated with guilt. A discussion of the findings obtained and their significance in theory and in practice is undertaken.
