Mediation of the intervention effect on alter CC screening by alter participant measures

The first step to identifying potential mediators of the intervention effect on alter CC screening was to identify variables that were associated with the intervention as well as alter CC screening. Starting with alter participant measures, Table 
Linear regression models of intervention effects on index cervical cancer (CC)-related processes (mediators) at month 6, controlling for baseline measure of the mediator* p values from bivariate comparisons using independent 2-tailed t-testsBeta coefficients and standard errors (SE) are from multiple linear regression models of index CC-related at month 6 as the dependent variable, and independent variables consisting of intervention condition and the baseline measure of the CC-related processTable With alter measures of CC knowledge, CC risk management self-efficacy, and engagement in CC prevention advocacy each being associated with both the intervention and alter CC screening, we then conducted mediation analysis to assess whether each measure mediated the intervention effect on alter CC screening, in separate logistic regression models. Change in alter engagement in CC prevention advocacy from baseline to month 6 fully mediated the intervention effect on alter CC screening (see Table

A two-step approach was used to test each potential mediator separately. In step one (“without mediator column”), the dependent variable was alter uptake of CC screening by month 6, while independent variables consisted of an indicator of study arm and the baseline measure of the mediator. In step two (“with mediator column”), the month 6 measure of the mediator was added to the model. Covariates included in each model consisted of age < 35 years, any secondary education, and presence of a main sex partnerOR = odds ratio; CI = confidence interval; bsln = baseline; M6 = month-6 follow-up visit
