This study aims to explore a novel conceptualization of Borderline Personality Disorder (BPD) as a "Relationship Use Disorder." The research proposes that BPD shares key features with behavioral addictions, specifically addiction to interpersonal relationships. The study builds upon previous findings suggesting that individuals with BPD experience intense emotional dysregulation, including negative self-perception, shame, and a compulsive need for external validation. This addiction to relationships, much like substance use disorders, is thought to contribute significantly to the difficulties faced by these individuals, including interpersonal conflicts, self-destructive behaviors, and emotional instability.Read full original descriptionShow less
Conceptualizing Borderline Personality Disorder as a Relationship Use Disorder
This study aims to explore a novel conceptualization of Borderline Personality Disorder (BPD) as a "Relationship Use Disorder." The research proposes that BPD shares key features with behavioral addictions, specifically addiction to interpersonal relationships. The study builds upon previous findings suggesting that individuals with BPD experience intense emotional dysregulation, including negative self-perception, shame, and a compulsive need for external validation. This addiction to relationships, much like substance use disorders, is thought to contribute significantly to the difficulties faced by these individuals, including interpersonal conflicts, self-destructive behaviors, and emotional instability.
The study seeks to demonstrate that the relational difficulties central to BPD meet the diagnostic criteria for addiction as defined by the DSM-5. It will also explore how these relational struggles are mediated by dysfunctional self-perception and whether they are linked to behaviors such as compulsive sexual behaviors (CSBD) or suicidal tendencies. Additionally, the research will investigate the relationship between addiction to relationships and neurobiological factors, including endorphin levels, in individuals with BPD compared to those with bipolar disorder and healthy controls. The hypothesis is that individuals with BPD will exhibit higher levels of relationship addiction, with this addiction being tied to their perception of self-worth and emotional experiences in relationships.
This innovative approach aims to refine the understanding of BPD, reduce stigma, and improve treatment strategies by providing scientific evidence supporting the conceptualization of BPD as a "Relationship Use Disorder."
