The qualitative variables have been subjected to basic statistic tests, with frequency tables, determination and comparison of percentages and use of Chi-square. It has been accepted a significant level of 5% considering the void hypothesis if p>0.05.

The non-compliance psychotic people have been the 100%. We have established a gender comparison finding differences between the analyzed variables. The most significant results are presented in the tables and graphics. We emphasize the category with the greatest percentage n in each variable.
