The purpose of this study was to explore how Mexican American adolesce
nts (N = 120) would perform on the MMPI-A given that Hispanic adolesce
nts were seriously underrepresented in the national norming sample dur
ing the development of the MMPI-A. The participants completed the MMPI
-A, a short demographic questionnaire, and a 5-item version of the Acc
ulturation Rating Scale for Mexican Americans. Results indicated that
the present sample of Mexican American adolescents' performance on the
Validity, Clinical, and Content scales differed minimally from the na
tional norming group's performance, and their performance varied as a
function of their levels of acculturation and socioeconomic status. Im
plications of these data are discussed.
