The psychometrics proprieties of the DASS-21 will be assessed. The psychometric sensitivity of the items will be estimated by measures of central tendency, variability and shape, the construct validity by factorial, convergent and discriminant validity. The reliability of the DASS-21 will be assessed by the Cronbach's alpha standardized. The mean final scores of the depression, anxiety and stress will be computed using matrix of regression by confirmatory factorial analyses. The study of association between consumption of medicine and practice of self-medication according to demographic variables will be performed by the chi-square (c2). To compare the mean final scores of Depression, Anxiety and Stress according to the consumption of medicine and the practice of self-medication and demographic variables will be used Analysis of Variance (ANOVA) if certificated the assumptions of normality and homoscedasticity. For multiple comparisons, post-test Tukey will be used. For decision making, the 5% level of significance will be used.
