Data Analysis
Data analysis was done using SPSS software version 23. To evaluate the normality of the data distribution, we used the Kolmogorov–Smirnov test. Chi-square test was used to compare two groups based on qualitative variables. Also, paired t-test and Wilcoxon test were used for within-group comparisons, and Mann–Whitney U test was used to compare other quantitative variables between the groups. Moreover, analysis of covariance (ANCOVA) was used to eliminate the effect of age and education level on the findings. Cohen's d effect size was calculated for within-group and between-group changes. The effect sizes of 0.8, 0.5 and 0.2 were considered large, medium, and weak, respectively [
