THE VALIDITY OF CLINICAL JUDGMENTS OF SCHIZOPHRENIC PATHOLOGY BASED ON VERBAL RESPONSES TO INTELLIGENCE TEST ITEMS.

The article discusses the validity of clinical judgments of schizophrenic pathology-based on verbal responses to intelligence test items. The reliability of clinical judgment has been the subject of a series of studies using single responses to intelligence test items obtained from psychiatric patients and judgments by trained clinicians based on a seven-point rating scale. It has been possible to demonstrate reliability in judgments of disorganization in schizophrenic thinking, as well as more specific aspects of schizophrenic thinking. The question now arises whether clinicians can make global appraisals of complete test protocols with as great reliability as they can judge single test items. This paper extends the study of reliability, defined as interjudge agreement, to global judgments in which whole protocols are ranked according to severity of schizophrenic pathology.
