Comparison of dependent variables between the two groups
Hypotheses 1–5, 8, and 9 were supported as changes in the pre- and post-scores were lower in the control group compared to the intervention group, and these changes were statistically significant. Scores were -0.41 vs 0.04(t = 2.73, p = .039), 2.42 vs 1.96(t = 1.82, p = .042), 0.37 vs 0.08(t = 3.82, p = .012), 11.12 vs 1.00 (t = 2.22, p = .040), and 1.32 vs 0.48(t = 2.25, p = .040), 1.33 vs 0.48(t = 2.07, p = .042), 7.88 vs 0.73(t = 2.41, p = .031) for hypotheses 1, 2, 3, 4, 5, 8, and 9 respectively. However, hypotheses 6 and 7 were not supported because there were no statistically significant differences in the changes between the intervention and the control groups. values were 2.02 vs 1.70(t = -0.54, p = .492) and 0.04 vs 0.04(t = 0.092, p = .982), respectively.
