Abstract

This study was conducted to examine the effectivity of invalid profile identification strategies with MMPI profiles of 700 invalid responses, 553 psychiatric patients, 326 normal populations, and 209 undergraduates. For this purpose this study executed discriminant analysis in which 10 clinical scales as well as validity scales, CA, TR, Korean version MMPI scales(NP, NSc) were included. The results showed that valid response and invalid response were highly accurately classified. Also, this criterion were stable in cross validation. It was discussed whether different identification strategies were used in different groups and the type of invalid profiles was understood. Considering that massive scoring, using computer automatic scoring, is being pervasive, we can expect that identification strategies suggested by present study may be effective.
