Notes: The r-effect size was used to calculate the effect sizes for nonparametric data. In this calculation, the effect size (i.e., r) is obtained by dividing the Wilcoxon Z score by the square root of the sample size; . Cohen’s guidelines for are small effect ≥ 0.1, medium effect ≥ 0.3, or large effect ≥ 0.5; +: small, medium, and large effect sizes; , , .
