Note: Weighted data.

aIncludes current smokers and those who quit in the past year. N = 2 were excluded because of missing data on past-year quit attempts; thus, the number of non-smokers and past-year smokers does not sum exactly to the number of participants in the whole sample.

bHigher scores indicate stronger non-smoking norms. The range of possible scores is given in parentheses.

cValid percentages shown, since some respondents did not have a partner (n = 206 in whole sample).
