Abstract:
This paper describes the methodology used to translate the MCMI-III into Brazilian Portuguese and presents results from a reliability study conducted in Brazil with the translated instrument. The sample was comprised of 222 Brazilian college students. Test-retest correlations between first and second testings (over a period of 7 to 14 days) ranged from .70 to .93 across 27 scales. Cronbach's alpha coefficients ranged from .54 to .87. The procedures described in this paper represent preliminary steps in the development of a Brazilian Portuguese translation of the MCMI-III. Further studies are needed to obtain reliability data with a clinical sample, evaluate the diagnostic validity of the scales, and derive appropriate base rates for the Brazilian population.
