Note. All measures were assessed among smoking and nonsmoking participants at each time point, unless otherwise noted.

^aAdjusted for baseline value of each variable plus baseline measures of self-efficacy for quitting, perceived likelihood of quitting in next 30 days, number of times ever quit smoking, Fagerström Test for Nicotine Dependence score, perceived smoking-related disease susceptibility, and perceived smoking-related disease severity.

^bLikert scale ranging from 1 = “not at all” to 5 = “extremely.”

^cAnalyses limited to continuing smokers only (n = 485) at the 1-month follow-up.

^dLikert scale ranging from 1 to 6, where nonsmokers at 1 month have been assigned a score of 6.

^eAssessed at 1-month follow-up only.
