CARVALHO, Lucas de Francisco  and  PRIMI, Ricardo. Validity evidences for PDDI based on external variables. Aval. psicol. [online]. 2013, vol.12, n.3, pp. 387-395. ISSN 1677-0471.

This study aimed to find evidence of validity based on the relationship with external variables to Personality Disorders Dimensional Inventory (PDDI), including convergent and discriminant validity by correlating the test with the Millon Clinical Multiaxial Inventory III (MCMI-III) and criterion validity seeking to predict the presence of psychiatric disorders. The participants were 350 people, whose ages ranged between 18 and 67 years, and 71.7% were female. Participants were divided into two groups: Group Not Psychiatric (GNP, n= 276) and Psychiatric Group (PSG, n= 74). All participants answered both, PDDI and MCMI-III. The data found in the analysis point to convergence between the instruments, as well as the PDDI ability to discriminate people with pathological personality functioning and healthier people. We also found good sensitivity for the instrument, but not so much favorable for the specificity of PDDI.
