A Review of Literature Regarding Scientific Controversies Surrounding the Psychometric Properties of the Rorschach Inkblot Test
Park, Kevin Neil
Online Submission, Psy.D. Doctoral Paper, Biola University
The Rorschach Inkblot Test has been the focus of intense controversy, significantly impacting clinicians who currently rely on Exner's Comprehensive System (CS; Exner, 2003) in clinical and forensic settings. This paper evaluates recent empirical CS research to determine whether or not it reveals lack of scientific merit as some skeptics have claimed. Relevant psychometric properties of the Rorschach are identified and evaluated to determine whether they meet accepted standards applicable to other psychological instruments in current use. Past reviews and recent empirical research published from 1998 to 2008 are critically reviewed. Specific properties under investigation in this controversy are validity (incremental, convergent, and construct), reliability (interrater, test-retest), standardized procedures, and normative data. This literature review critiques a sample of recent empirical research related to each of these categories, and the findings generally reveal average to excellent psychometric properties. Trained and experienced examiners can use the Rorschach with confidence in its scientific legitimacy, and charges that call for a moratorium on the Rorschach due to insufficient empirical backing are rejected. The Rorschach should continue to be scrutinized in peer-reviewed journals using criteria similar to those applied to other psychological instruments. The legitimacy and utility of the Rorschach should be based on unbiased empirical evidence, and results should be communicated clearly to all consumers of Rorschach data in clinical, educational, and forensic settings. Areas of future research are discussed under the assumption that weaknesses in certain aspects of the Rorschach do not equate to illegitimacy of the CS as a whole. (Contains 2 tables.)
