The Dimensional Clinical Personality Inventory (IDCP) was developed in Brazil for the assessment of pathological personality traits. This study aimed to seek validity evidence for the dimensions of IDCP based on external criteria, psychiatric diagnosis. We examined the profile in IDCP of 105 psychotherapy outpatients, previously diagnosed with personality disorders. The profiles were compared with the profile of the normative non-clinical sample and we conducted the repeated measures analysis to investigate whether the IDCP is able to discriminate consistent profiles for different diagnoses and compared the general population. The results suggest validity evidence based on external criteria for the IDCP dimensions and points to the clinical effectiveness of the instrument.
