Associations of categories of the Extended Parallel Process Model (EPPM) with attitudes and beliefs regarding a pandemic influenza emergency (unadjusted for demographic characteristics).

aThe odds ratio compares this category to the Low Threat/Low Efficacy category as the Reference.
bThe number of participants included in the analysis for each question was approximately 1680.
cAll responses in the High Threat/High Efficacy category were positive. In order to provide an accurate yet reasonable representation of the relationship between this and the Low Threat/Low Efficacy category, a weighted logistic regression analysis (SAS) was performed adding 0.1 to each cell count. The odds ratio and confidence interval indicate that the odds of a positive response to the attitude/belief is exceedingly greater for the High Threat/High Efficacy group than for the Low Threat/Low Efficacy group.
