Abstract:
In order to investigate the research progress on nicotine dependence scales relating to e-cigarettes, heated tobacco products and waterpipes, the preparation considerations and psychometric characteristics of the existing dependence scales for the three kind products were reviewed. According to the literatures, there have been 9 scales related to e-cigarettes, 3 related to heated tobacco products and 8 related to waterpipes. The results showed that: 1) In terms of preparation considerations, most of the scales were established on the basis of the cigarette dependence test via product substitution and/or item addition/deletion. Some scales were directly applied, and only a few were newly developed. 2) In terms of scale structure, most of the scales presented a multi-factor structure and comprehensively evaluated the dependence from multiple aspects. 3) In terms of psychometric characteristics, most scales adapted from cigarette dependence scales appeared to have a higher homogeneity reliability, indicating the similarities of dependence among the three products and cigarettes; the reliability of a few adapted scales were lower than that of the original cigarette versions, which might be caused by inapplicability of the evaluation content. With regard to validity, most scales inclusive of validity test had good criterion-related validity or construct validity. However, there was a lack of biochemical indicator evaluation. Further study could focus on developing multi-dimensional scales, optimizing items and using criterion validity to evaluate the dependence.
