On the assessment of thought disorder from the Rorschach

While the Rorschach has been proven useful in assessing severity of thought disorder, the assessment of extent of thought disorder evidenced in any one protocol is made subjectively, that is, on the basis of clinical impression. Objective methods for assessing thought disorder on the Rorschach were reviewed and evaluated. Problems in the development of such methods which have limited their psychometric efficiency were discussed, and possible solutions of these problems were suggested. Since severity of thought disorder relates to prognosis and treatment, the further exploration of more effective ways of assessing thought disorder by the Rorschach seems warranted.
