摘要

Background: The smoking prevalence was found higher among vocational school students comparing to general high school in Taiwan, and the difference is rising each year. Smoking cessation reduces many smoking-related health risks; therefore it is essential to explore the intentions to quit smoking and their associated factor among these students. Appropriate intervention then can be provided to prevent students becoming future daily smokers. Purpose: The purpose of this study is to assess the correlation between adolescents' intention to quit smoking, attitude, subjective norm, and perceived behavior control, by applying the principal components of Theory of Planned Behavior (TPB). Methods: A cross-sectional study was conducted in a junior college in southern Taiwan, in 2009. Self-report questionnaires were administered and 799 students aged 16-18 responded (response rate 83.8%). And among them, 203 were smokers. Pearson correlation and linear regression model were employed to analyze the association between intention to quit smoking and the components of TPB. Results: The results of this study indicate that attitude, subjective norm, and perceived behavior control were positively correlated to students' intention to quit smoking. The results of Hierarchical regression analyses showed that the best predictors for intention to quit smoking was perceived behavior control with 23.7 % of total variance explained (F(8, 194)=7.546, p＜.001). Moreover, 15.2 % of the total variance in individual's intention to quit smoking was attributable to family smoking status, cost of cigarettes and quitting experiences. Conclusions: After adjusting for demographic factors, smoking status, smoking experiences and the components of Theory of Reasoned action, perceived behavior control is found effective to explain the intention to quit smoking among adolescent smokers. Therefore, it is recommended to improve the ability of self-control over smoking cessation impediments in order to increase the intention to quit smoking.
