For the SIS-Total score, a trend in difference between the two groups was observed (F(1,15) = 3.9, p = 0.068) and the pairwise comparison showed a trend for greater improvement in the intervention group compared to the control group at both T1 (mean difference = 5.7, F(1,20.2) = 3.5, p = 0.077) and T2 (mean difference = 5.3, F(1,20.2) = 3.1, p = 0.094), although none of them were statistically significant.
