Mechanism of community quitters’ psychological traits on their smoking cessation effects: Based on a study of community intervention

INTRODUCTION: We study the relationship between psychological traits of smokers and their smoking cessation effects, and provide more scientific evidence for smoking cessation intervention. METHODS: The study was conducted as a nested case-control study. Smokers who participated in the community smoking cessation intervention projects in Beijing in 2018–2020, were selected as the research participants and divided into two groups: a successful smoking cessation and unsuccessful smoking cessation group, according to their smoking cessation effects at 6 months. Psychological traits of quitters including smoking abstinence self-efficacy, willingness to quit smoking, and trait coping style, were compared between the two groups, and a structural equation model was established for confirmatory factor analysis to analyze their mechanisms. RESULTS: There were differences in smoking cessation results between the successful smoking cessation group and the unsuccessful smoking cessation group in terms of smoking abstinence self-efficacy and willingness to quit smoking. Willingness to quit smoking (OR=1.06; 95% CI: 1.008–1.118) is a risk factor, while smoking abstinence self-efficacy in habit/addiction situations (OR=0.77; 95% CI: 0.657–0.912) is a protective factor. The results of the structural equation model showed that smoking abstinence self-efficacy (β=0.199, p=0.002) and trait coping style (β= -0.166, p=0.042) could influence smoking cessation effects. The structural equation model was well fitted, which showed that smoking abstinence self-efficacy (β=0.199, p=0.002) and trait coping style (β= -0.166, p=0.042) might have influenced the effect of smoking cessation among smokers. CONCLUSIONS: Willingness to quit smoking has a positive impact on the smoking cessation effect, while smoking abstinence self-efficacy in habit/addiction situations and negative trait coping style have a negative impact. Smoking abstinence self-efficacy and trait coping styles can significantly affect smoking cessation outcomes.
