Schizophrenic psychopathology is heterogeneous and multidimensional. One of the more fruitful strategies to investigate more homogenous domains of psychopathology has been the positive-negative syndrome approach. However, this approach is unable to address a number of important issues. Most schizophrenics present a mixed syndrome; the criteria for what constitutes a positive and negative syndrome are variable; distinguishing primary from secondary negative symptoms can be difficult. In order to address some of these problems, we propose the introduction of a 5-syndrome model based on a reanalysis of factor-analytic procedures used on 240 schizophrenics assessed with the Positive and Negative Syndrome Scale: A negative, positive, excitement, cognitive and depression/anxiety factor. This 5-factor solution is supported by 4 independent and comparable factor analyses. Data on internal consistency of the 5 factors and on initial validation using demographic and clinical variables are presented.
