a Sociodemogrpahic variables (age category, race/ethnicity, education, partner’s education, work status, awareness about HPV vaccine, and history of abnormal Pap smears) with a P value < 0.1 based on bivariate logistic regression analysis where vaccine initiation and completion in daughters and sons were dependent variables in separate models were included in the multivariate models. However, variables with a P value > 0.1 in the initial multivariate model were removed from the final multivariate models (education, partner’s education, work status, and history of abnormal Pap smears). Age categories and race/ethnicity were forced in the models if the P value did not achieve significance at <0.1 level. ; bVaccine initiation or completion were not observed in this category of decision making.
