Salameh等人。开发了黎巴嫩水烟依赖量表(LWDS-11)，评估成年水烟吸烟者对尼古丁的依赖。鉴于黎巴嫩青年和其他邻国的高水烟使用情况，认为有必要检查最初适用于黎巴嫩人口的LWDS-11的心理测量特性，以衡量青少年对尼古丁的依赖程度。进行了两次横断面调查；研究一(2019年1月和5月)共招募了449名吸食水烟的学生；本样本被用来进行探索性因素分析。研究2招募了另一个样本，由243名抽水烟的青少年组成。此样本独立于第一个样本，用于进行验证性分析。312例(69.5%)[95%可信区间0.652~0.738]存在高度的水管依赖(≥评分为10分)。样本1的因子分析结果表明，LWDS-11的所有条目都是经过因子分析提取的。项目收敛于一个因素的解；总方差解释 = 70.45%，αCronbach(= 0.96)。验证性因素分析的结果如下：最大似然卡方 = 129.58和自由度 = 45，得出χ2/df = 2.88。对于非中心性拟合指数，Steiger-Lind均方根逼近误差为0.08[0.071-0.106]。此外，比较拟合指数(CFI)为0.77。初步结果表明，LWDS-11具有较好的测量青少年水烟依赖的心理测量学特性。我们希望这一工具能为研究和流行病学服务。
Salameh et al. developed the Lebanese Waterpipe Dependence Scale (LWDS-11) that assesses nicotine dependence among adult waterpipe smokers. In view of the high waterpipe use among Lebanese youth and other neighboring countries, it was deemed necessary to check the psychometric properties of the LWDS-11, originally adapted to the Lebanese population, to measure nicotine dependence among adolescents. Two cross-sectional investigations were conducted; Study 1 (January and May 2019) enrolled a total of 449 students who were exclusive waterpipe smokers; this sample was used to conduct the exploratory factor analysis. Study 2 enrolled another sample composed of 243 waterpipe smoking adolescents. This sample was independent from the first one and was used to conduct the confirmatory analysis. The results also showed that 312 (69.5%) [95% CI 0.652–0.738] had high waterpipe dependence (scores of ≥10). Results of the factor analysis in sample 1 showed that all LWDS-11 items were extracted following the factor analysis. Items converged over a solution of one factor; total variance explained = 70.45%, αCronbach = 0.96). The results of the confirmatory factor analysis were as follows: the Maximum Likelihood Chi-Square = 129.58 and Degrees of Freedom = 45, which gave a χ2/df = 2.88. For non-centrality fit indices, the Steiger-Lind Root Mean Square Error of Approximation (RMSEA) was 0.08 [0.071–0.106]. Moreover, the Comparative Fit Index (CFI) value was 0.77. The preliminary results suggest that the LWDS-11 has good psychometric properties to measure waterpipe dependence among adolescents. We hope this tool would serve the benefit of research and epidemiology.
