The Whitaker Index of Schizophrenic Thinking was designed to address an important clinical and research problem–the objective assessment of thought disorder. The present study assessed this test's convergent and discriminant validity and its diagnostic discriminating power ( N = 56). We found that the WIST has limited clinical utility as a specific measure of disordered thought and as a diagnostic tool, but that it might still have certain important research applications.
