For the numerical results extracted from the questionnaires, we ran a test of normality (Shapiro-Wilk test ). The data were analyzed using the nonparametric Wilcoxon test when the Shapiro-Wilk test indicated a non-normal sample distribution (pvalue < 0.05), while a paired t-test was performed when the Shapiro-Wilk test indicated that the sample distribution is not significantly different from a normal distribution (p-value > 0.05).
