Abstract

This study aimed to develop an instrument for personality disorders assessment and seek for validity
evidence based on the internal structure of this instrument. The developed instrument, the Dimensional
Inventory of Personality Disorders (IDTP), was applied to 350 participants, from 1 8 to 67 years, of both
sexes. First and second order exploratory analyzes by principal components were performed, correlations
between the scales of the instrument, and calculated the alpha’s Cronbach coefficients. According to the
literature and specifically the diagnostic categories for personality disorders, most hypothesized factors
were found for the test and the alpha coefficient ranged between .65 and .89. Furthermore, the secondorder
factor structure, consisting of three factors, was consistently according to prior literature.
