Abstract:
Intervention based on the intention to quit smoking was essential for successful cessation. This quasi-experimental research aimed to study the effects of smoking cessation program applying the Transtheoretical model (TTM). The group and individual program activities for 8 weeks were divided and designed in accordance with the stage of change (SOC) in smokers. The samples comprised 32 smokers living at Wongwon Sub-district, Kuntung District, Trang Province. Data were collected by questionnaires at the pre and post intervention phase on the 4th and 8th week. Statistical analysis was performed by using descriptive statistics and inferential statistics, Paired Samples t-test and Repeated measures ANOVA. The results revealed that samples had significantly higher scores in decisional balance, self-efficacy, and quitting at 4th and 8th week after intervention as compared to the pre-intervention phase (p-value < 0.05). Most samples moved through a series of SOC, from 18.8 percent on precontemplation stages and 37.5 percent on contemplation stage at pre-intervention phase to 28.1 percent on preparation stages and 71.9 percent on action stages at 4th week, and most participants were on action stages (75.0 percent) and followed by 25.0 percent on preparation stages at 8th week. After 8 weeks intervention program, 12 smokers were able to quit smoking, at 37.5 percent. In conclusion, the smoking cessation program applying the Transtheoretical Model and social support can help smokers to stop smoking. The intervention program could be applied in smoking cessation services provided in the health centers. Health care providers should assess the intention to quit smoking and then arrange the smoking cessation program by their stages of change as well as continuously provide social support to quit.
