Type: Structured questionnaire.

Main indications: Designed to assess the presence of personality disorders.

Rating performed by: Trained interviewer.

Time period covered by scale: The patient's lifetime history.

Time required to complete rating: 25 minutes.

Remarks: Rates the patient, using 175 true–false questionnaires, by 20 scores:

• eight relate to basic personality styles (schizoid, avoidant, dependent, histrionic, narcissistic, antisocial, compulsive, passive–aggressive)
• three relate to pathological personality syndromes (schizotypal, borderline, paranoid)
• six relate to symptom disorders scales of moderate severity (anxiety, somatoform, hypomanic, dysthymia, alcohol abuse, drug abuse)
• three relate to symptom disorder scales of extreme severity (psychotic thinking, psychotic depression, psychotic delusions).
  

Two additional correction scales provide a means of identifying and adjusting possible test-taking distortions. The scale enables diagnoses of 14 personality disorder subtypes (using DSM-IV) to be made.
