Effects of online social media on improving mothers’ behaviors towards preventing their children’s otitis media based on the PRECED model: a randomized educational intervention trial

Table 4 Comparing of mean and standard deviation the difference in scores of attitude and behavior in the experimental and control group before and after intervention

Constructs of PRECEDE model	Groups	Before	After	score difference before and after intervention	*p Value
Constructs of PRECEDE model	Groups	Mean (S.D)	Mean (S.D)	score difference before and after intervention	*p Value
Attitude	Experimental	4.0 ± 0.6	4.5 ± 0.31	0.5 ± 0.4	< 0.001
Attitude	Control	4 ± 0.6	3.8 ± 0.56	0.1 ± 0.2	< 0.001
Behavior	Experimental	3.2 ± 0.5	3.6 ± 0.2	0.4 ± 0.5	< 0.001
Behavior	Control	3.4 ± 0.6	3.4 ± 0.5	-0.03 ± 0.1	< 0.001

Due to the significant difference between the mean scores before and after the educational intervention in the control group, separately for those constructs, the difference in scores before and after the educational intervention was calculated for each of the intervention and control groups, so the comparison between them was done with independent t-test
