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.

By incorporating reliable measures of depressive and hyperthymic temperamental characteristics in subtype definitions, we achieve the sharpest possible demarcation between unipolar and bipolar disorders. The new procedures also reveal that 1 out of 3 primary depressives in a consecutive series of 405 patients belong to the bipolar spectrum. Furthermore, among bipolars, bipolar II disorder (redefined as major depressions with hypomania or hyperthymic temperament) represents the most common variant. We discuss the nosologic, therapeutic, methodologic and theoretical implications of these considerations on the unipolar-bipolar dichotomy. Given that major depression emerges as the final common clinical expression of a heterogeneous group of disorders, it underscores the importance of focusing on temperament and course of illness in subclassification efforts such as attempted here.
