Summary

This study aims to develop a typology-based intervention delivered by smoking cessation (SC) counsellors to prevent smoking relapse in ex-smokers who recently quit. The two main research questions include (1) Can a typology-based smoking relapse prevention intervention be feasible and accepted by the smokers and SC counsellors who deliver the new intervention? (2) What is the preliminary evidence on the efficacy of the typology-based smoking relapse prevention to increase tobacco abstinence in ex-smokers who have recently quit? If the intervention shows at least a small effect size (i.e. risk ratio\>1.3), or the intervention is feasible while modifications can potentially increase the efficacy, a future definitive RCT is warranted.
