[The Strauss-Carpenter Scale: evaluation of its prognostic value for the 5-year outcome of schizophrenic patients].

An adequate prognosis of schizophrenic psychoses cannot be made on the basis of single variables. Therefore prognostic scales combining prognostically relevant items should be tried. The prognostic value of the scale of Strauss and Carpenter, the predictive accuracy of which has been described in the Anglo-American literature, was tested in a 5-year follow-up study on patients with schizophrenic or similar psychoses. A high correlation was found between the total score and all outcome criteria. Although many single items reached a high prognostic relevance, the total score of the scale was superior.
