title: Usefulness of the International Personality Disorder Examination Screening Questionnaire for borderline and impulsive personality pathology in adolescents.
abstract: The aim of this study was to analyze the usefulness of the International Personality Disorder Examination Screening Questionnaire (IPDE-SQ) for identifying DSM-IV and ICD-10 Borderline and Impulsive personality disorders (PD) in Spanish adolescents.
  
  
  METHODS
  The DSM-IV and ICD-10 IPDE-SQ screeners were used and compared with the diagnoses obtained with the IPDE semistructured interview in a sample of 125 adolescents treated in a psychiatric department.
  
  
  RESULTS
  For primary screening, the cutoff point with the best combination of sensitivity and specificity for ICD-10 impulsive and borderline PDs was obtained with three positive items, whereas for DSM-IV borderline the best PD cut-off was five positive items. For secondary screening, the best option would be one item above the cut-off points proposed for primary screening.
  
  
  CONCLUSIONS
  The 3-item cut-off point in the IPDE-SQ produces a high proportion of false positives on impulsive and borderline PDs in clinical adolescents. We propose several cut-off points, depending on whether the study is designed to perform primary or secondary screening.
