- OBJECTIVES
The purpose of this study was to test the Theory of Planned Behavior (TPB) in the prediction of smoking cessation intention and smoking cessation behavior among adolescent smokers, in order to provide basic data to develop a future smoking cessation program as a nursing intervention.
METHOD
The study subjects were 80 adolescent smokers who had smoked one cigarette and attended a five-day school smoking cessation program. The data were collected from October 24 to December 21, 1999. The instruments used in this study were the tools developed by Jee (1994) to measure TPB variables such as attitude toward smoking cessation behavior, subjective norm, perceived behavioral control, smoking cessation intention, and smoking cessation behavior. The data were analyzed with the SAS/PC program using descriptive statistics, hierarchical multiple regression, and logistic multiple regression.
RESULTS
1. Attitude toward smoking cessation behavior, subjective norm, and perceived behavioral control were partially significant in predicting smoking cessation intention.
2. Smoking cessation intention and perceived behavioral control toward smoking cessation behavior did not significantly predict smoking cessation behavior.
3. There were partial interaction effects among the attitude toward smoking cessation behavior, subjective norm, and perceived behavioral control in the prediction of smoking cessation intention.
4. There were partial interaction effects between smoking cessation intention and perceiver behavioral control toward smoking cessation behavior in the prediction of smoking cessation behavior.
CONCLUSION
This study partially demonstrated support for the TPB model that was partially useful in predicting smoking cessation intention and smoking cessation behavior among adolescent smokers. Therefore, it is recommended that attitude toward smoking cessation behavior and perceived behavioral control should be considered in developing smoking cessation programs and implementing nursing interventions to change the smoking behavior of adolescent smokers.

- This study was designed to investigate the effects of a smoking cessation school program on attitudes towards smoking cessation the subjective norm perceived behavioral controls the intent to cease smoking and smoking behavior. Also included was the goals of the program itself.
Study subjects were 80 adolescent smokers who at least attended the smoking cessation school program without absence had smoked one cigarette at the time of the first study before the program and attended the first second and third studies (The study was conducted from September 26 to December 21 1999. a period of 59 days).
Data collection was performed using the TPB questionnaire which was developed by Jee Yon-Ock (1994) The survey included questions covering the intended areas of study mentioned above. The first data was collected during the first day of the five day program. The second survey was conducted immediately after the last day of the program and the last survey was four weeks late.
Data was analyzed with a SAS/PC program including N, %, a paired t-test.
The results were as follows: 1. After the program the scores representing attitude towards smoking cessation (before program: 14.5 after program: 16.8) and perceived behavioral control (before program: 1.2 after program: 2.1) rose significantly but the scores for attitudes towards the subjective norm and the intent to cease smoking were not notably different.
2. After the program the frequency of daily smoking fell significantly (before program: 5.7 cigarettes after program: 3.2 cigarettes).
In conclusion the five day smoking cessation school program increased attitude perceived behavioral control and decreased smoking behavior but did not influence subjective norm smoking cessation intention. Thus further study is required to better evaluate the effects of the program and th improve any shortcomings.
