Meanwhile, the average self-efficacy before intervention in the control group was 6.37 with a standard deviation of 3.774, while the average value after intervention in the control group was 7.00 with a standard deviation of 3.058. The results of further analysis using the Wilcoxon test obtained a p-value of <0.05.
