Smoking cessation interventions are important because university students are vulnerable to smoking and good health practices during their university lives greatly affects their health status. The purpose of this study is to investigate the factors affecting smoking cessation success among the university students who participated in the 4-week smoking cessation program. Methods: This study was conducted with 101 university student smokers. To identify the factors affecting the success of smoking cessation, a logistic regression analysis was performed. Results: In Model 1, without the smoking cessation aids variable, when the frequency of face-to-face counseling was greater, the success rate of smoking cessation was 1.70 times higher. In Model 2, including the smoking cessation aids variable, when the nicotine dependence score was higher, the success rate of smoking cessation was 0.72 times lower, and when the number of smoking cessation aids used was greater, the success rate of smoking cessation was 1.40 times higher. Conclusion: Smoking cessation aids are essential to increase the success of short-term smoking cessation, and face-to-face counseling and telephone counseling should be provided continuously to maintain long-term smoking cessation.
