title: [Validation of the "Assessment of DSM-IV Personality Disorders (ADP-IV)" Questionnaire].
abstract: OBJECTIVE
  The "Assessment of DSM-IV Personality Disorders (ADP-IV)" represents a 94-item questionnaire that allows for a categorical and dimensional assessment of the DSM-IV personality disorders.
  
  
  METHODS
  Psychometric properties of the German ADP-IV were investigated in 400 psychotherapy outpatients and a community sample of 385 persons. The SCID-II interview and a standardised expert consensus rating were employed for the assessment of concurrent validity.
  
  
  RESULTS
  The ADP-IV showed satisfactory reliability; the median Cronbach's alpha for the subscales was .76 (range .65-.87), the median retest reliability .79 (range .37-.88). Factor analysis revealed an 11-factor solution that explained 49.4% of the variance. The median correlation of the dimensional ADP-IV subscale scores with the SCID-II and the expert consensus ratings were .51 (range: .34-.72) and .44 (range: .27-.62), respectively. The kappas for the chance corrected agreement of categorical ADP-IV diagnoses with the SCID-II diagnoses and the expert ratings were .35 and .29 for any personality disorder and a median of .37 and .30 for the specific personality disorders.
  
  
  CONCLUSIONS
  The ADP-IV shows satisfactory reliability and a validity that is comparable and partly superior to other self-rating instruments. The advantages of the instrument are its brevity, the inclusion of distress ratings, and the dimensional scoring that allows for the construction of detailed profiles of personality pathology.
