Psychometric equivalence of the computer and booklet forms of the MMPI: A meta-analysis

Inconsistent findings have repeatedly been found by researchers attempting to determine whether the computer form of the Minnesota Multiphasic Persona lity Inventory (MMPI) is psychometrically equivalent to the booklet form. T his article applied psychometric meta-analysis to pool results from all ava ilable studies to examine the equivalence: of the computer and booklet MMPI forms. Means, standard deviations, and crossform correlations were cumulat ed. A comprehensive meta-analysis of the literature demonstrated that the d isparate findings can be explained in terms of sampling error across indivi dual studies. Differences in means and standard deviations across studies w ere near 0, and crossform rank orderings were near perfect. The results of this study suggest that the computer and booklet forms of the MMPI are psyc hometrically equivalent.
