title: Psychometric properties of the German version of the borderline personality disorder severity index--version IV.
abstract: BACKGROUND
  Although the borderline personality disorder severity index--version IV (BPDSI-IV) has already been used in several studies, psychometric properties are only known from two developing studies.
  
  
  METHODS
  To examine item characteristics, reliability, and validity indicators, a large sample including subjects with borderline personality disorder (n = 163), a mixed psychiatric group (n = 58), and a healthy control group (n = 43) were interviewed with the German version of the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) as well as the BPDSI-IV.
  
  
  RESULTS
  The indices for interrater reliability as well as internal consistency of the BPDSI-IV were excellent to good. The total score and the subscales of the BPDSI-IV discriminated between diagnostic subgroups. As expected, its subscales were associated with the scores in the SCID-II and applied self-rating measures.
  
  
  CONCLUSIONS
  In a subsequent version, subscales might have to be adapted to the proposed traits of the borderline type in DSM-V.
