本研究检验了与香烟相比，电子烟和无烟烟草（SLT）的感知危害的直接和间接测量的有效性。在直接测量中，人们将一种产品与另一种产品进行比较，而在间接测量中，人们分别对每种产品进行评级，研究人员对这些评级进行比较。对2013-2014年烟草与健康人口评估（PATH）研究第1波青少年数据进行分析（N = 13,651名12-17岁青少年）。该研究包括对电子烟和SLT与香烟相比的感知危害的直接测量，以及通过比较产品评级创建的间接测量。加权多项逻辑回归通过评估直接和间接测量是否与标准变量（包括电子烟和SLT的使用）相关来检验标准效度。青少年更有可能认为电子烟的间接危害比香烟小（67.3%），而不是直接危害（50.2%）。同样的模式也适用于SLT比香烟危害小的评级（间接：29.7%；直接：11.7%）。直接测量解释了产品使用标准变量的独特方差，即使在调整了间接测量后也是如此，间接测量在调整了直接测量后也是如此。然而，标准变量往往与直接测量相关联，而不是间接测量。结果为在评估青少年对各类产品的感知相对危害时使用直接和间接措施提供了初步支持。然而，如果研究人员不能在研究中包括直接和间接的测量，与产品使用标准变量的关联支持优先考虑直接测量。Elsevier Ltd.出版。
This study examined validity of direct and indirect measures of perceived harm of e-dgarettes and smokeless tobacco (SLT) compared to cigarettes. On direct measures, people compare one product to another, whereas on indirect measures, people rate each product separately and the researcher compares these ratings. Data from youth in Wave 1 of the Population Assessment of Tobacco and Health (PATH) Study (2013-2014) were analyzed (N = 13,651 youth aged 12-17 years). The study included direct measures of perceived harm of e-cigarettes and SLT compared to cigarettes, and indirect measures were created by comparing ratings of the products. Weighted multinomial logistic regressions tested criterion validity by assessing whether direct and indirect measures were associated with criterion variables, including use of e-cigarettes and SLT. Youth were more likely to rate e-cigarettes as less harmful than cigarettes on the indirect measure (67.3%) than the direct measure (50.2%). The same pattern held for ratings of SLT as less harmful than cigarettes (indirect: 29.7%; direct: 11.7%). Direct measures explained unique variance in product use criterion variables even after adjusting for indirect measures, as did indirect measures after adjusting for direct measures. However, the criterion variables were more often associated with the direct measures than the indirect measures. Results offer preliminary support for using both direct and indirect measures when assessing youth's perceived relative harm of various types of products. However, if researchers cannot include both direct and indirect measures in a study, associations with product use criterion variables support prioritizing direct measures. Published by Elsevier Ltd.
