One major determinant of external validity is the representativeness of the sample. This article provides data to help authors and readers assess the generalizability of samples from smoking studies
We analyzed the 2007 U.S. National Health Interview Survey.
We provide means, SEMs, and 95% CIs for demographic and smoking behavior characteristics of never-smokers, ever-smokers, all current smokers, current daily smokers, current nondaily smokers, long-term ex-smokers, and smokers who made a quit attempt in the last year.
Our results can help studies assess generalizability, set targets for recruitment, or reweigh data to reflect U.S. averages.
影响外部有效性的一个主要因素是样本的代表性。本文提供了数据,帮助作者和读者评估吸烟研究样本的可推广性。
我们分析了 2007 年美国国家健康访谈调查的数据。
我们提供了从不吸烟者、曾吸烟者、所有当前吸烟者、当前每日吸烟者、当前非每日吸烟者、长期戒烟者以及去年尝试戒烟者的人口统计学和吸烟行为特征的平均值、标准误和 95%置信区间。
我们的结果可以帮助研究评估可推广性、设定招募目标,或重新加权数据以反映美国的平均水平。
