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."

| Function Acquisition Speed Test (FAST) | Administer the Function Acquisition Speed Test (FAST) to measure how quickly individuals learn associations between stimuli and responses, focusing on emotional biases related to self (e.g., feelings of unworthiness, ridicule) and others (e.g., dependency, validation). The aim is to assess the intensity of emotional biases in BPD patients compared to BD patients and healthy controls. |

| Measured at baseline |
| Visual Analogue Scale (VAS) for Perceived Alignment with BPD | After viewing an educational video explaining Borderline Personality Disorder (BPD) as relational addiction, assess how participants perceive the alignment of their personal experiences with BPD traits, using a Visual Analogue Scale (VAS) ranging from 0 to 10. | Measured at baseline |
| Love Addiction Inventory (LAI) | Using the Love Addiction Inventory (LAI), a 24-item self-report scale, to measure symptoms of love addiction. Participants rate their responses on a 5-point Likert scale, with higher scores indicating greater levels of love addiction symptoms, among patients with Borderline Personality Disorder (BPD) without Bipolar Disorder (BD), those with BD without BPD. | Measured at baseline |
| Beta-Endorphin Levels | valuate the correlation between beta-endorphin levels and the dimension of relational addiction among patients with BPD, BD, and healthy controls | Measured at baseline |
| Dysfunctional Self-Perception and Related Indicators (SES) | Assessing dysfunctional self-perception and its associated indicators-including feelings of emptiness - among BPD group, BD group and HC group, using :
| Measured at baseline |
| Dysfunctional Self-Perception and Related Indicators (RSES) | Assessing dysfunctional self-perception and its associated indicators-including self-esteem-among BPD group, BD group and HC group, using : - Rosenberg Self-Esteem Scale (RSES): A 10-item self-report scale assessing global self-worth. The total score ranges from 0 to 30, with higher scores indicating higher self-esteem. | Measured at baseline |
| Dysfunctional Self-Perception and Related Indicators (ESS) | Assessing dysfunctional self-perception and its associated indicators-including shame,-among BPD group, BD group and HC group, using : - Experience of Shame Scale (ESS): A 25-item self-report scale covering eight domains of shame experiences, including personal habits, interpersonal behaviors, and body image. Higher scores reflect greater shame experiences. | Measured at baseline |
| Dysfunctional Self-Perception and Related Indicators (VAS) | Assessing dysfunctional self-perception and its associated indicators-including shame,-among BPD group, BD group and HC group, using : - Visual Analog Scale (VAS) for Psychological Pain: Participants mark a point on a 10 cm line that represents their current level of psychological pain. Higher values indicating greater psychological pain. | Measured at baseline |
| Painful Experiences Related to the Relational Object (MSR) | Assessing the impact of painful relational experiences, focusing on rejection sensitivity, among patients diagnosed with Borderline Personality Disorder (BPD) without Bipolar Disorder (BD), those with BD without BPD, and healthy controls (HC), using : - Rejection Sensitivity Scale (MSR): A 9-item self-report scale assessing the level of anxiety and likelihood of perceiving rejection in various interpersonal situations. Higher scores indicate greater sensitivity to rejection. | Measured at baseline |
| Painful Experiences Related to the Relational Object (ESUL) | Assessing the impact of painful relational experiences, focusing on loneliness, among patients diagnosed with Borderline Personality Disorder (BPD) without Bipolar Disorder (BD), those with BD without BPD, and healthy controls (HC), using : - University of Laval Loneliness Scale (ESUL): A 20-item self-report scale measuring perceived loneliness in adults. The scale assesses both emotional and social loneliness. Higher scores indicate greater loneliness. | Measured at baseline |
| Painful Experiences Related to the Relational Object (RSQ) | Assessing the impact of painful relational experiences, focusing on attachment styles, among patients diagnosed with Borderline Personality Disorder (BPD) without Bipolar Disorder (BD), those with BD without BPD, and healthy controls (HC), using : - Relationship Scale Questionnaire (RSQ): A 30-item self-report scale evaluating attachment styles and relational anxiety.
