Table 6.

Confidence levels compared across time points.

Group	n	Pre-learning experience confidence level Mean (SD)	Post-learning experience confidence level Mean (SD)	Mean difference (95% CI)	p-value
Control	16	1.1 (0.5)	2.7 (0.7)	1.5 (1.2, 1.9)	<0.001
Intervention	18	1.3 (0.6)	2.8 (0.7)	1.5 (1.1, 1.8)	<0.001

Confidence levels were assessed using Likert-type rating scales, with 1 representing no confidence and 5 as maximum score. Mean scores (standard deviation) are presented. Confidence levels were examined using paired t-tests to examine the difference between the pre-learning and post-learning scores in each group. A p-value < 0.05 was considered statistically significant.SD – standard deviation, CI – confidence interval.
