Exploring MMPI-Rorschach relationships

Limitations exist in the current literature examining Minnesota Multiphasic Personality Inventory (MMPI)-Rorschach interrelationships. In this article I attempt to identify several issues to be addressed by researchers in this area. These include restricting conclusions about MMPI-Rorschach relationships to research using the Comprehensive System; considering the relative reliability and validity of these tests; comparing the predictive power of the Rorschach and MMPI; examining the effects extreme outliers have on statistical analyses; and determining the appropriate level of analysis for research, the level of individual test scores, or psychological constructs. The implications of these issues for research design, statistical analysis, and applied clinical work are discussed.
