The purpose of this study was to identify the effects of a smoking cessation program on the amount of smoking and nicotine dependence and the self-efficacy of smoking cessation for smoking workers.

The total number of subjects was 38 smokers and was divided into two: 16 smokers were placed in the experimental group and 22 in the control group. A nonequivalent control group pretestposttest design was used. The smoking cessation program consisted of two sessions and was implemented for two hours daily for five days. Data was analyzed by using the SPSS/WIN 11.0 program with χ²-test, t-test or Mann-Whitney U and ANCOVA.

After the treatment, those belonging to the experimental group showed a significantly decreased amount of smoking, a decreased nicotine dependency and increased self-efficacy compared to the control group.

The smoking cessation program was effective for diminishing the amount of smoking, decreasing nicotine dependence and improving self-efficacy. Therefore, this program is recommended as a smoking cessation strategy for adult smokers.
