After the completion of the eight-week intervention, higher mean change scores of the EBS and lower mean change scores of he EBBS were seen in the ESMI group than in the C and PE groups. When the three groups were compared using the Kruskal–Wallis test, significant differences in both the mean change scores of the EBS and EBBS were revealed at T1(p < 0.01), T2(p < 0.01) and T3 (p < 0.01), respectively (Figs. 3 and 4).
