Efficacy of Nursing Intervention Based on Trans- Theoretical Model of Change of Smoking Cessation

Tobacco use is the major avoidable cause of disease and death. This investigation was undertaken to evaluate the efficiency of trans-theoretical model of change in smoking cessation among secondary school teachers in Tabriz by use of nursing intervention. This investigation was a quasi-experimental research. Participants in this research were 200 male graduate teachers of five educational districts in Tabriz. Subjects were randomly divided to two control and experimental groups (100 in each). The independent variable was nursing smoking cessation intervention and dependent variables were: self-efficacy, decisional balance, and smoking behavior. Data collection instruments were socio-demographic and smoking history, smoking behavior, self-efficacy and decisional balance questionnaires. Descriptive and analytical statistic (dependent and independent T-test, x2, and . . .) was used for testing the research hypothesis. Results showed 48 (58.5%) subjects of experimental group quite smoking completely after nursing intervention (x2 = 44.336, p<0.001). Comparison of smoking behavior (t=6.482, P<0.001) and self-efficacy (t=6.697, P<0.001) in experimental group before and after intervention, showed statistical significant difference. Decisional balance in experimental group before and after intervention, and also in comparison with control group, did not had significant difference. Although trans-theoretical change model was useful in designing nursing smoking cessation intervention, but more research is needed for decisional balance construct in diverse cultural groups.
