The usefulness of the Rorschach Prognostic Rating Scale--a rebuttal

In rebuttal to the recent article by Garwood (1977), this paper presents a framework for evaluating the usefulness of the Rorschach Prognostic Rating Scale for predicting success in psychotherapy. A critical review of the research findings cited by Garwood is presented, followed by a discussion of the overall usefulness of the instrument as a predictive measure in light of the framework suggested. It is concluded the scale is not yet proven to be of great clinical usefulness, as its degree of discriminability is not great enough for basing clinical judgments.
