This paper reports on a study to establish the psychometric properties of the Chinese version of the dimensions of Tobacco Dependence Scale as these apply in Taiwan.
The instruments for measuring cigarette dependence among adolescent smokers are not available in Taiwan. Therefore, it has not so far been possible to assess such dependence.
Survey.
A sample comprising 293 adolescent smokers was recruited. They were drawn from nine senior high schools in middle and southern Taiwan. The Dimensions of Tobacco Dependence Scale and the Fagerstrom Test of nicotine dependence were administered, with saliva being subjected to salivary cotinine analysis using competitive enzyme immunoassay kits.
The internal structure of the Dimensions of Tobacco Dependence Scale (DTDS) was first examined using exploratory factor analysis with promax rotation. By applying the parallel test as the means of selection, four criteria emerged from the factor analysis that accounted for 47.7% of the variance. Concerning criterion validity, the DTDS was found to have a positive and significant association with the Fagerstrom test of nicotine dependence scores (r = 0.58; p < 0.01) and with saliva cotinine levels (r = 0.30; p < 0.01). Cronbach's alpha values for the DTDS were 0.94.
The study confirmed that the Chinese version of the DTDS is similar to the English version in that it is multidimensional and has consistent factor structures. And, as a result of the study, it was established that the Chinese version of the Dimensions of Tobacco Dependence Scale is a reliable and valid measure of tobacco dependence among adolescents in Taiwan.
The DTDS can provide health professionals with a reference measure for assessing adolescents' tobacco dependence when applied in the context of a smoking cessation programme.
本文报告一项关于确立中文版烟草依赖量表维度在台湾地区的心理测量学特性的研究。
台湾地区尚无用于测量青少年吸烟者香烟依赖程度的工具。因此，目前尚无法评估此类依赖情况。
调查研究。
招募了293名青少年吸烟者作为样本。他们来自台湾中南部的九所高中。对其施测烟草依赖量表维度及尼古丁依赖的法格斯特龙测试，并使用竞争性酶免疫分析试剂盒对唾液进行唾液可替宁分析。
首先采用promax旋转的探索性因素分析对烟草依赖量表维度（DTDS）的内部结构进行检验。通过将平行测试作为选择手段，因素分析得出四个标准，它们解释了47.7%的方差。在效标效度方面，发现DTDS与尼古丁依赖的法格斯特龙测试得分呈显著正相关（r = 0.58；p < 0.01），与唾液可替宁水平也呈显著正相关（r = 0.30；p < 0.01）。DTDS的克朗巴哈α值为0.94。
该研究证实，中文版DTDS与英文版相似，具有多维度且一致的因素结构。并且，通过该研究确定，中文版烟草依赖量表维度是台湾地区青少年烟草依赖的可靠且有效的测量工具。
在戒烟项目中应用时，DTDS可为健康专业人员提供评估青少年烟草依赖的参考指标。
