Comparison of CCD training on knowledge, attitude, and efficacy between the intervention and comparison groups

Variables	Intervention group (n = 69)	Comparison group (n = 53)	Delta difference	p-value
	Delta mean score ± SD	Delta mean score ± SD
Knowledge	2.73 ± 2.13	2.35 ± 2.24	0.38	0.342a
Attitude	3.78± 7.21	0.72 ± 6.11	3.06	0.050*b
Efficacy	2.62 ± 3.82	1.96 ± 3.73	0.66	0.341a

Note:

^*p <0.05; ** p <0.01; *** p <0.001;

^aIndependent t-test:

^bMann-Whitney test; SD (standard deviation)

Delta means score = mean score after intervention- mean score before intervention
