Objective: To assess the effect of a group intervention on smoking cessation based on social cognitive theory.
Methods: A total of 217 smokers were recruited through mobilization in the community. Six-month and 2-year follow-up surveys were engaged after intervention to evaluate the effectiveness of the training.
Results: Smoking quitting rate confirmed by biomarker level in the 2-year follow-up survey could achieve 32.3% and the successful quitting rate could be 15.2%. The factors influencing smoking cessation at 2-year follow-up could be associated with diseases related to smoking (AOR = 4.09), the change in self-efficacy scores (AOR: 1.05-1.13) and home smoke-free policy (AOR= 5.07).
Conclusion: The group intervention on smoking cessation based on social cognitive theory could be effective and can be used in community.
