  1. aThe repeated measures ANOVA
  2. bThe one-way ANOVA
  3. ¥: According to Tukey’s post-hoc test: There was a significant difference between the mean total scores of PSRI and Group A-C and Group A-B (P < 0.001) but there was no significant difference between the mean total scores of PSRI and Group B-C (P > 0.05)
