This study aims to identify predicting factors influencing Chinese students’ intentions to quit smoking.
Secondary data for this study came from a study on the change in smoking cessation among Asian students. Data on their intention to quit smoking was collected from October 2020 to January 2021 through an online survey. The study participants included 190 Chinese international students aged 19 to 29 who were smokers. Descriptive statistics, chi-squared test, independent-test, and decision-making trees were used for analysis.
73.2% (139 students) of Chinese international students in Korea intended to quit smoking; 97.8% of the groups intending to quit smoking had previously attempted to quit. The decision tree ultimately had seven sections. The attempt to quit smoking was the most significant predictor of smoking cessation intention. Stop smoking attempts, intent to participate in a nonsmoking programs, smoking parents, stop-smoking self attempts, and smoking after studying abroad were factors predicting intention to quit smoking.
The factors influencing Chinese students’ intention to quit smoking differed depending on their previous smoking cessation experience. Intention to participate in a smoking cessation program, parent smoking, and recent attempts to quit smoking were factors predicting intention to quit in those with previous smoking cessation experience. A program tailored to their needs should be developed to improve the smoking cessation intention of Chinese international students depending on their history of smoking cessation.
