2 factor analyses were performed on nurses' ratings of the ward behavior of 417 acute schizophrenic patients. The 10 psychotic syndrome scores which Lorr, McNair, Klett, and Lasky (1962) derived from behavior observable in an interview were included in one of the analyses. 11 factors labeled Self-Care, Social Participation, Extraversion, Irritability, Anxiety, Guilt Feelings, Depression, Feelings of Unreality, Slowed Speech and Movements, Paranoid Projections, and Excitement were extracted from the ward behavior ratings. There was good correspondence between the factors of psychopathology extracted from patient ward behavior and the Lorr et al. psychotic syndromes.
