Understanding Rorschach Research: Using the Mihura (2019) Commentary as a Reference.

Mihura's (2019) recent commentary on Smith et al.'s (2018) article, "A Scientific Critique of Rorschach Research: Revisiting Exner's Issues and Methods in Rorschach Research (1995)" raised several issues surrounding our internal validity criteria and our approach to validating Rorschach research. Mihura also conducted additional statistical analyses that failed to address important, critical issues. In this article, we further clarify the importance of refining internal validity criteria for Rorschach research and Rorschach metaanalytic studies (our 2018 article). We offer this information and analysis to guide the Rorschach consumer toward a better understanding of how to assess the validity of Rorschach data and empirical findings. Criticisms of our criteria for evaluating Rorschach research (inter-rater reliability, IQ/Education level, Rorschach Responses, Lambda/F%, sample size) and our recommendation to include descriptive data for critical variables in all published Rorschach studies contradict accepted standards for Rorschach research. Mihura stated that "the associations between the Rorschach and self-report measures were not used to determine the validity of Rorschach variables" (p. 171) in her meta-analyses. Consequently, we applied our methodological criteria to only Mihura's externally assessed criteria studies (removing self-report studies; 67%) and found that 91% had three or more problems related to internal validity (13 had counter-intuitive findings). In addition, other central issues related to meta-analyses, application/validation studies, and counter-intuitive findings regarding the Rorschach were discussed. [ABSTRACT FROM AUTHOR]
