description
We replicated prior research on Rorschach and MMPI-2 convergent validity by testing 8 hypotheses in a new sample of patients. We also extended prior research by developing criteria to include more patients and by applying the same procedures to 2 self-report tests: the MMPI-2 and the MCMI-II. Results supported our hypotheses and paralleled the prior findings. Furthermore, 3 different tests for methodological artifacts could not account for the results. Thus, the convergence of Rorschach and MMPI-2 constructs seems to be partially a function of how patients interact with the tests. When patients approach each test with a similar style, conceptually aligned constructs tend to correlate. Although this result is less robust, when patients approach each test in an opposing manner, conceptually aligned constructs tend to be negatively correlated. When test interaction styles are ignored, MMPI-2 and Rorschach constructs tend to be uncorrelated, unless a sample just happens to possess a correlation between Rorschach and MMPI-2 stylistic variables. Remaining ambiguities and suggestions for further advances are discussed.
