Abstract
One hundred and fifty-five DSM-IIIR schizophrenic patients were assess ed for positive and negative symptoms using Andreasen's Scale for Asse ssment of Positive Symptoms (SAPS) and the Scale for Assessment of Neg ative Symptoms (SANS). Interrelationships of individual positive and n egative symptoms were examined using a factor analysis. Results of the factor analysis are consistent with Liddle's proposition that there a re three syndromes underlying symptomatology in schizophrenia: disorga nization; psychomotor poverty and reality distortion.
