Of the 162 treatment group respondents who reported remembering at least one postcard, hence could answer questions about the study, 136 answered all of the questions used in this analysis. Unstandardized coefficients. Unless otherwise noted, for all scales 1 = “Strongly disagree” to 5 = ”Strongly agree.” *P < 0.10, **P < 0.05, ***P < 0.01.
