Statistical grouping of clinical symptoms and signs is one method of classifying schizophrenia. This study attempted to find factors of symptoms generated through clinical ratings on three scales, namely the Scale for the Assessment of Positive Symptoms (SAPS), the Scale for the Assessment of Negative Symptoms (SANS) and the Comprehensive Psychopathological Rating Scale (CPRS) in a sample of 80 stable chronic schizophrenics diagnosed by DSM-III-R. It was found that the positive-negative dichotomy could not be replicated. Inappropriate affect was found to be a clear misfit in the cluster of negative symptoms. Inclusion of CPRS led to the generation of a factor loading high on depressive and asthenic items, and this could be clearly distinguished from the factor of negative symptoms. This factor had not hitherto been identified.
