A cross sectional study examining social desirability bias in caregiver reporting of children’s oral health behaviors

Table 4 Multivariate log binomial regression modeling results of caregiver report “Decided not to brush my child’s teeth because it would be frustrating” [(adjusted prevalence ratio (PR) and 95% confidence limits ^* (CL)] on Oral Health Literacy (OHL) among the WIC/UNC participants (n = 102)

	Model A	Model B	Model C	Model D^‡
	PR (95% CL)	PR (95% CL)	PR (95% CL)	PR (95% CL)
Oral health literacy (REALD-30 score)^†	0.96 (0.92, 0.99)	0.96 (0.92, 0.99)	0.95 (0.92, 0.98)	0.94 (0.89, 0.98)
Age (years; quartiles)		1.24 (0.88, 1.74)

Other				0.97 (0.37, 2.53)

Change in estimate (percent)	ref	vs. A: 6.4	vs. A: 16.5	vs. C: 14.7

*confidence limits were based on robust standard errors; †estimate corresponds to one-unit change in REALD-30 score; ‡ denotes the ‘final’ Model; the education, income, and number of kids variables did not meet the 10% change-in-estimate criterion and thus were not included in the final model (Model D).
