In turn, other empirical studies point to approximately 75% of borderline cases experiencing transient dissociative and paranoid symptoms. The evidence reports that around 20–50% of patients with borderline PD experience psychotic symptoms, also that psychotic disorders are observed in 38% of these patients and the prevalence of 20% of psychotic disorder diagnosis not otherwise specified is the most common subtype. Returning to the influential review of Gunderson and Singer in defining borderline patients, based on the main publications of psychiatric and psychoanalytic contributions, two characteristics have already been highlighted - brief psychotic experiences and the psychological testing performance with bizarre, dereistic, illogical or primitive responses - among the six features most often described as characterizing borderline conditions. Likewise, the contributions of empirical research on the DSM-5 dimensional approach to this topic are also uncommon. Moreover, the comparative studies that acknowledge their links to affective psychoses are even more scarce. Psychotic spectrum features in borderline personality disorder (PD) are a long-standing phenomenon, but remarkably, to date, they have not been the focus of many empirical studies. The innermost relationship of the borderline concept and psychosis has been historically intertwined and can be traced back to the twentieth century. The pathological personality nature of the psychotic features emerges as a potential comprehensive trait of the phenomenological dimensions. Conclusionsīesides the commonality that appears to overlap both disorders with a psychosis superspectrum, the patterns of the pathological personality-symptoms underlying the psychotic features appear to reinforce a position between schizophrenia and bipolar disorders that borderline PD may occupy, highlighting the possibility of its intersection with schizoaffective/psychosis spectra. Borderline PD has the highest score in BSI paranoid ideation which emerges as its discriminating trait (Nagelkerke R 2 = .58): cognitive and perceptual dysregulation (OR: 13.02), restricted affectivity (OR: 12.09), withdrawal (OR: 11.70), anhedonia (OR: 10.98) and emotional lability (OR: 6.69). Overall, the data emerging as common predictors are detachment, negative affectivity, psychoticism, depressivity, grandiosity, suspiciousness and interpersonal sensitivity symptoms. A series of linear and logistic regression analyses were computed. Self-reported assessment: Personality Inventory for DSM-5 (PID-5) Brief Symptom Inventory (BSI). MethodsĪ cross-sectional study of two clinical samples: 1) Borderline PD group of 63 participants 2) Bipolar disorder group of 65 participants. This study seeks to identify the best set of pathological personality traits and/or symptoms that are predictors of psychotic features (psychoticism and ideation paranoid symptoms) in borderline PD and in bipolar disorder, based on the framework of the DSM-5 section III personality traits. Mary reports that before she began dating her current partner she sometimes engaged in sexual activity with multiple people per week, often with partners whom she did not know.Psychotic spectrum features in borderline personality disorder (PD) are a long-standing phenomenon, but remarkably, to date, they have not been the focus of many empirical studies. Immediately after doing so, she reports feeling regret and panic at the thought of him leaving her. At times, she thinks that her partner is “the best thing that’s ever happened to me” and will impulsively buy him lavish gifts, send caring text messages, and the like however, at other times she admits to thinking “I can’t stand him,” and will ignore or lash out at him, including yelling or throwing things. She states, “I don’t know who Mary really is,” and describes a longstanding pattern of changing her hobbies, style of clothing, and sometimes even her job based on who is in her social group. When she is stressed, Mary says that she often “zones out,” even in the middle of conversations or while at work. She has made two suicide attempts by overdosing on prescribed medications, one as a teenager and one six months ago she also reports chronic suicidal ideation, explaining that it gives her relief to think about suicide as a “way out.” Mary is a 26-year-old African-American woman who presents with a history of non-suicidal self-injury, specifically cutting her arms and legs, since she was a teenager.
