Equivalency of computer-assisted and paper-and-pencil administered versions of the Minnesota Multiphasic Personality Inventory-2

The literature on computer-assisted and paper-and-pencil administered Minnesota Multiphasic Personality Inventories (MMPIs) was reviewed. Both computer-assisted and paper-and-pencil administered formats for the MMPI-2 were then investigated. Results found the two formats to be quite comparable. Neither the validity nor the clinical scales differed by format in terms of means and standard deviations. Groups also showed homogeneity of variance across formats. Test-retest reliabilities between the two formats were significant and compared favorably with those reported for repeated paper-and-pencil testings. Stability of high-point codes appeared comparable with past research. Equivalence concerning the presence or absence of clinical elevations across the two formats appeared quite good, showing 92–97% agreement. Subjects expressed preference for the computer-assisted format, reporting more comfort with its pace and that they found it more interesting, less difficult, and more enjoyable. Results suggested that the absence of an overt ‘cannot say’ option may be the optimum presentation choice for this scale.
