Charts of 100 schizophrenic inpatients, of whom half deteriorated and half recovered, were rated on the Becker-Wittman and Phillips Prognostic Scales by a rater blind to the long-term follow-up. Scores on both scales were highly correlated with each other, with follow-up status, and with a process or nonprocess classification by an independent rater. Five factors extracted from a correlation matrix of scores on individual score items were similar to those prognostic variables previously described by others.
