Resumo

This article presents rule induction algorithms for identify and evaluate variables related to social vulnerability risk factors of the individual that influence the diagnosis of psychotic disorders. 213 variables were analyzed: sociodemographic, psychic experiences in the community, traumas in childhood, bullying, and use of marijuana, tobacco, and alcohol. Four subsets were constructed and with them, we reach an attribute reduction of 80%. In development, an accuracy of approximately 80% was maintained. About the number of rules there was a reduction of 90% of possibilities generated, simplifying the representation of the model. Thus, the results proved promising for the use of this approach as a basis in the construction of decision support systems in the area and in the deepening of studies for the incorporation of new variables in psychiatric diagnosis, increasing the reliability and validity of the diagnostic process.
