Note. HPV = human papillomavirus, N/A = not applicable due to variable being continuous. Mothers’ willingness measured using 5-point scale ranging from “definitely not willing” to “definitely willing” (coded 1–5). β represents standardized regression coefficients. Multivariate models included only those variables displayed in table. Mothers’ education level, urbanicity, region of residence, and whether mothers had talked with their sons about HPV vaccine were not included in the multivariate models since they were not correlated with either willingness outcome in bivariate analyses. For rows reporting βs, interaction assesses whether one of them is larger.
