A sample of 182 first onset schizophrenics were studied by means of the PANSS(Positive and Negative Syndrome Scale). A review of the previous factor analysis suggest that schizophrenic symptoms cannot be appropriately classified into positive and negative syndromes. Using confirmatory factor analyses, we then statistically compared four theoretically derived models(1, 2, 3, 4 factor model) of the structure of schizophrenic symptoms. Our results fit better with Liddle's model of three syndrome(psycho-motor poverty, disorganization, reality distortion). It is argued that the positive-negative dichotomy appears to be an oversimplification and suggested that either more factors or different symptoms are required to account well for the latent structure using exploratory factor analyses included general psychopathology scale.
