 We will conduct the following secondary analyses to evaluate whether parents who receive the intervention have greater HPV vaccine knowledge, information seeking, and PAPM stage progression compared to parents receiving usual care. Among those who consented for additional contact and completed pre-clinic and follow-up surveys, we will explore associations among intervention assignment and intermediate factors including parents HPV vaccine knowledge, attitudes, perceived risk, information-seeking, and HPV vaccine decisional stage. Descriptive statistics will be calculated and outliers identified. A correlation matrix will be run to check for multicollinearity strong correlations between intermediate factors. We will run univariate and multivariate logistic regression models to determine whether intervention assignment is associated with greater knowledge of the HPV vaccine, more positive attitudes toward and information seeking about the HPV vaccine, and PAPM stage progression.
