Introduction:
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
Methods:
We analyzed the 2007 U.S. National Health Interview Survey.
Results:
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.
Discussion:
Our results can help studies assess generalizability, set targets for recruitment, or reweigh data to reflect U.S. averages.
