Introduction: Mania and depression are today the main components of bipolar disorders. They are considered opposite sides of the same illness in spite of the fact that they are present simultaneously in almost 40% of the cases. This has been called the bipolar spectrum. Objective: A confirmatory factorial analysis of the manic syndrome is carried out in order to establish its principal factors, the weight of its symptoms, and adequate diagnostic criteria. Method: Observational, analytic and prospective study that was accomplished in three steps: Diagnostic confirmation, application of the Universidad Nacional Mania Scale (EMUN), and statistical analysis. Next, the matrix was evaluated and the confirmatory factorial analysis with a maximum precision method was performed. Results: In 202 patients we established four factors. The most important factor was motor activation and the least important factor was affective symptoms. These results were similar in our former study. Conclusion: Our results do not agree with standard classification systems as they did not establish affective symptoms as the main factor of the manic syndrome. In our study affective symptoms were the least important factor of the syndrome.
