Equivalence between Computer and Booklet Administrations of the New Japanese Version of the MMPI

Abstract

The New Japanese Version of the Minnesota Multiphasic Personality Inventory (MMPI) was administered twice at an interval of 7 days to female college students in order to verify the equivalence of the computer- (C) and booklet-administered (B) formats. Two hundred subjects completed one or both measures in one of four groups: C/B, B/C, C/C, and B/B. Each group was composed of 50 subjects. ANOVAs were applied to the raw scale scores of the C/B and B/C groups. On the D, Pa, Pt, and Sc scales, the scores on the computer were statistically significanfly higher than those on the booklet administration. This result differed from the results of the previous studies. This might be attributed to the language and software used for computerization. The correlations between the formats were slighdly lower than or equal to their test-retest reliability coefficients. The computerized MMPI did not save administration time, which may have been due to the software specifications.
