In this study, 123 nonpatient adults residing in central California were administered these three instruments. We performed intercoder 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. Although norms are fundamental to the interpretation of both clinical and research protocols, a survey of the literature reveals few peer-reviewed nonpatient Rorschach, Wechsler Adult Intelligence Scale-Revised (WAIS-R), or Minnesota Multiphasic Personality Inventory-2 (MMPI-2) studies done by researchers not associated with the standardization projects for these instruments. Specifically, we could find no studies in which the Rorschach was used together with either of these tests to provide information on normative functioning. Such a study would provide current nonpatient data and allow direct comparisons across instruments. In 1994 we set out on a 3-year project in which we administered all three instruments to a sample of nonpatients. Our intent was to provide current information on how a group of nonpatients perform on three widely used psychological tests. Although our findings are similar to smaller samples used as controls in recent hypothesis-testing studies (e.g., Frueh & Kinder, 1994; Netter & Viglione, 1994), our intent was not a nonpatient versus clinical-sample comparison. It was, instead, an attempt to provide the sort of descriptive data that can accrue when the same nonpatients take the Rorschach, WAIS-R, and MMPI-2.

The principal author was the sole examiner. Inclusion criteria are described. Interrater reliability statistics at the response level are presented along with scores for the Rorschach Comprehensive System (CS; Exner, 2003). The results revealed differences from the published norms on variables that reflect poor form quality, fewer popular responses, more attention to detail, more poor human relationship responses, and a more simplistic, affective-free approach to the environment, among others.
