However, there was a significant difference between the post-test mean scores of the control and intervention groups in this case, which was 29.66±1.90 11 and 45.14±2.12 respectively. In addition, there was no significant difference between the pre-test mean scores of nurse’s practice in the intervention and control groups (11 and 14, respectively) (p=1.000), but there was a significant difference between the post-test scores, which were 93.96±7 and 93.74±7.74 respectively (p=.008).
