Background: Measuring nicotine dependence is an essential part of smoking cessation program. for which FTND is widely used. Heavy Smoking Index which is consisted of ’daily amounts of cigarette’ and ’time to first cigarette’ has already been proved as a valid tool, but there isn’t no comparable study in Korea. It aims to verify the usefulness of HSI in
comparison of FTND, especially in the area of mass survey and clinics.
Methods: We gathered socio-demographic factors and smoking history from those who visited 250 public health centers, and took FTND questionnaire. We analysed the correlation between FNTD and HSI, and calculated the Cohen’s kappa coefficient to analyse the degree of agreement. And We calculated the sensitivity and specificity of HSI in according to FTND. We investigated whether each item could be useful for nicotine dependence measuring, as mentioned.
Results: The mean age of 8547 subjects is 44, and mean BMI is 23.7Kg/m2. The mean of total score of HSI is 3.0, and that of FTND is 4.6. Pearson correlation coefficient between HSI and FTND is 0.91, which is evaluated as high score. Cohen’s kappa coefficient is 0.71 which reflects high agreement between two tools. The sensitivity and specificity of HSI is 89% and 84%, respectively, in according to FTND. The Cohen’s kappa coefficient, sensitivity and specificity of each item is not reached for HSI
Conclusions: HSI which is consisted of 2 items is a reasonable substitute for the FTND, and may be efficiently used in the mass survey and the rapidly evaluating tool. (Korean J Health Promot Dis Prev 2007 ; 7(3):165~171)
