The differential criterion‐related validity of the MMPI and MMPI‐2 and their stability over a 4‐month period of time were examined in a university population by correlating the clinical scales with their counterpart SCL‐90‐R factors. Fair to moderate correlations were found on all eight paired MMPI scales and SCL‐90‐R factors, while only two of eight MMPI‐2/SCL‐90‐R pairings were found to be correlated significantly. Further analyses, however, found no significant differences between these MMPI/SCL‐90‐R and MMPI‐2/SCL‐90/R correlations. Adequate stability was found between MMPI‐2 and SCL‐90‐R pairs over 4 months, except for the MMPI‐2 D scale with SCL‐90‐R Depression factor. Several issues related to the equivalency between the MMPI and the MMPI‐2 were discussed.
