— The prevalence of Schneiderian first‐rank symptoms (FRS) in 294 consecutive admissions to a research unit was evaluated with reference to their diagnostic distribution (SADS/RDC). Thirty‐five of 58 patients with schizophrenia had FRS, as compared to nine of 190 patients with major depressive disorder. All patients with two or more FRS received a diagnosis of schizophrenia. In the absence of organic or toxic etiology, the specificity of FRS for schizophrenia was 95% and their predictive value was 90%. These findings indicate that FRS should be regarded as strongly suggestive of schizophrenia in the absence of an organic syndrome.
