Current nonpatient data for the Rorschach, WAIS-R, and MMPI-2

A literature review yields a surprisingly small number of nonpatient studies focusing on three widely used assessment tools: the WAIS-R, Rorschach, and MMPI-2. In this study, 123 nonpatient adults residing in central California were administered these three instruments. We performed interceder reliability statistics on 52 of the 123 Rorschach records. WAIS-R and MMPI-2 results are similar to current standardization data for these instruments, whereas many of the Rorschach variables are quite different from those published in the manual for the Comprehensive System(Exner, 1995). We discuss these findings and offer recommendations for further normative research.
