The Role of Basic Symptoms and Aberrant Salience in Borderline Personality Disorder

Background: The prevalence of pre-psychotic symptoms and aberrant salience in BPD has not been systematically studied. The present study aims to investigate the intensity, frequency and correlation between basic symptoms, aberrant salience and borderline personality traits, in subjects that have not yet developed a frank psychotic episode. Methods: Twenty-eight subjects, 8 males and 20 females, aged between 24 and 55 years (M = 41.36 ± 9.9) has been individually tested throughout the Frankfurt Complaint Questionnaire (FBF), the Aberrant Salience Inventory (ASI) and the Personality Inventory for the DSM-5- Adult (PID-5). Results: Findings showed that 85.7% of the sample (n = 24) reported significant scores of the aberrant salience traits, which in turn were correlated to basic symptoms. Furthermore, emerged several correlations between pre-psychotic symptoms and PID-5 personality dimensions not only with Negative Affectivity and Detachment but also with Psychoticism. Conclusions: This study highlights the phenomenological continuity between the borderline personality traits and the attenuated manifestation of the psychotic disease.
