From: The benefit of repetitive skills training and frequency of expert feedback in the early acquisition of procedural skills

  High-frequency feedback group (HFF group) N = 23 Low-frequency feedback group (LFF group) N = 24 MWU p-value 1
Prior to the training (T0) 2.35 ± .71 2.33 ± .64 .640
After Peyton’s step 4 (T1) 4.70 ± .59 4.86 ± .74 .296
After the final, sixth repetition (T2) 5.27 ± .39 5.37 ± .40 .872

  3. Self-efficacy ratings relating to five competencies in inserting a nasogastric tube between the two groups before the training (T0), after Peyton’s step 4 (T1), and after the final, 6th repetition (T2; mean and standard deviation of six-point Likert scales from 6 = fully agree to 1 = completely disagree; M-W-U-Test, p-values).
