A comparison of MMPI-A and MMPI-2 scores with 18-year-old college students.

Abstract

This study investigated the comparability of MMPI-2 and MMPI-A profiles for 18 year old college students. Forty-two undergraduate students completed both the MMPI-2 and the MMPI-A. Eleven participants' profiles were discarded due to K Scale elevations. The remaining 31 participants were divided into groups of 18 women and 13 men. Two repeated measures analysis of variance were used to analyze the data, one for men and one for women, The overall E test was significant for both groups; therefore, paired ~-tests were used in follow-up analyses. Correlation coefficients were also computed for each of the 3 validity and 10 clinical scales. The statistical results of these analyses suggest the MMPI-2 and the MMPI-A are not comparable instruments. Significant differences between the MMPI-2 and the MMPI-A were found on several scales, as well as several unacceptably low correlation coefficients. Future research should include information on each individual's living situation, as well as an external measure of psychopathology.
