a Wilcoxon test to verify if there were differences between the means of the different variables measured with questionnaires between the three measurement times for the experimental group. b the data for the Wilcoxon Z and significance are provided in the following order: differences between Time 1 and Time 2, differences between Time 2 and Time 3, and differences between Time 1 and Time 3. c The r corresponds to the effect size of the differences, calculated through the Rosenthal r (1991).
