Construct validation of scales derived from the Rorschach method: a review of issues and introduction to the Rorschach rating scale.
I suggest the main goal of Rorschach validation should be a refined understanding of what each score means. Toward this end, I review general issues in construct validity, hurdles unique to the Rorschach, and general limitations with validation criteria. I then recommend two approaches for improving criteria so they can begin approximating the gold standards that are necessary for a refined understanding of what scores actually measure. The first is a method for improving expert clinical judgment, and the second is a method for aggregating data across diverse judges. Finally, the Rorschach Rating Scale (RRS) is presented as a criterion tool to be used with either of these approaches to validation. The RRS is a fairly comprehensive summary of the constructs thought to be measured by various Rorschach scoring systems. The utility of the RRS for research and training are discussed, as are other practical, theoretical, and psychometric issues in its application.
