title: Borderline personality pathology in young people at ultra high risk of developing a psychotic disorder.
abstract: The association between borderline personality disorder and the ultra high risk (UHR) for psychosis state is unclear. The following study aimed to investigate the type of attenuated psychotic symptoms and prevalence of borderline personality pathology in a sample of UHR young people. Additionally, the study aimed to explore whether borderline personality pathology influenced the transition rate to psychosis.
  
  
  
  Medical records from Orygen Youth Health between 2007 and 2009 were examined. There were 180 patients who met UHR criteria and were included for analysis. Most patients were females (62.8%) and age ranged from 15 to 24 years.
  
  
  
  A quarter (25.2%) of UHR patients endorsed items consistent with borderline personality pathology. UHR patients with borderline personality pathology experienced a range of attenuated psychotic symptoms and could not be statistically differentiated from UHR patients with less significant or without borderline personality pathology. Borderline personality pathology did not increase or decrease the risk of developing a psychotic disorder. The absence of depression was the only predictor of psychosis.
  
  
  
  Many UHR patients present with concurrent borderline personality features. The psychotic experiences reported by UHR patients with borderline personality features were not limited to paranoid ideation, supporting the idea that borderline personality disorder may include a wider range of psychotic symptoms than previously thought. It is further possible that the psychotic symptoms experienced in this group could also be indicative of an emerging psychotic disorder.
