GEE modelling used; outcome assessed at wave following wave at which reasons for thinking about quitting and covariates were assessed.
Model 1 analyses adjusted for country, sex, age group, majority/minority group, education, income, CPD, TTFC, survey wave, time in sample and difference in time between waves.
Model 2 analyses adjusted for variables included in model 1 and each reason for thinking about quitting.
Ns for ‘concern for personal health’ are UK: N=3186 ind, 8215 obs; CA: N=3072 ind, 7875 obs; US: N=3040 ind, 6808 obs; AU: 3159 ind, 8327 obs, and vary slightly for other reasons.
*Association is stronger in the USA than in the UK (p<0.01).
†Association is stronger in the USA than in Australia (p<0.01).
‡Sum of reasons endorsed AOR indicates the increase in likelihood of making a quit attempt per an increase of one for total number of items endorsed.
AOR, adjusted OR; AU, Australia; CA, Canada; CPD, cigarettes smoked per day; GEE, generalised estimating equation; ind, individuals; obs, observations; TTFC, time to first cigarette.
