Remarks on method for MMPI-Rorschach studies.

An impressionistic list of methodological considerations that may be of consequence in Minnesota Multiphasic Personality Inventory (MMPI)-Rorschach studies is presented. These include the potential effects of the multidimensionality of the basic clinical MMPI scales in comparison studies, issues of deception and response style in such studies, and the rote of theory in guiding the selection of variables in the search for MMPI-Rorschach correspondences. The recently established necessity of controls for the total number of Rorschach responses provides the basis for suggestions for further controls in MMPI-Rorschach studies, including those for level of distress and for the minimization/exaggeration of psychopathology. An effort is made to contrast these two instruments in terms borrowed from information theory as a way of illuminating their complementary aspects, and suggesting means by which each may contribute to an enhanced understanding of the other.
