Five-Dimensional Personality Test: Development and Validation of a Persian Version

Dimensional approach to personality disorders conceptualizes personality disorders quantitatively different from normal personality. Five-Dimensional Personality Test (5DPT; Coolidge et al. in Pers Individ Differ 44(6):1326–1334, 2008) provides an assessment based on this approach. The 5DPT holds considerable usefulness and potential for investigating personality, and this potential may be much better utilized through availability of abbreviated versions and culture-specific forms. This paper describes efforts to develop and validate a Persian form of 5DPT. Findings of the study showed that some items of the original form were not able to represent the theoretical factors. However, discarding these items did not affect the factor structure of the new measure. It was demonstrated that the Persian version is composed of five saturated factors (neuroticism, absorption, orderliness, extraversion, and insensitivity) fitted to the data. Also, the structural equivalence of the two forms was discussed. Since the final scale turned out to be more concise, consisting of 75 of the original 100 items, application of this measure in research and clinical settings is facilitated.
