Effects of an examiner’s positive and negative feedback on self-assessment of skill performance, emotional response, and self-efficacy in Korea: a quasi-experimental study

Table 2 Comparison of groups for self-evaluated score and accuracy of self-evaluation

Variables		PF group (n = 58)	NF group (n = 52)	U	p	ANCOVA F (p)
Self-assessment score	Median (min, max)	37.0 (27, 38)	35.0 (30, 38)	693.0	< 0.001	18.37 (< 0.001)
Self-assessment score	Mean ± SD	36.8 ± 1.8	35.0 ± 2.0	693.0	< 0.001	18.37 (< 0.001)
Difference (self-test score)	Median (min, max)	1.0 (−3, 14)	1.0 (−2, 7)	1167.0	0.039	20.64 (< 0.001)
Difference (self-test score)	M ± SD	2.1 ± 3.2	0.8 ± 1.9	1167.0	0.039	20.64 (< 0.001)

ANCOVA was performed to examine the differences in dependent variables between the two groups after covariance treatment of unequal age and scores in the baseline characteristics. In this case, variables that did not satisfy the assumption of normality were transformed to natural logarithms
PF positive feedback, NF negative feedback
