Data to assess the generalizability of samples from studies of adult smokers.
BACKGROUND
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.


CONCLUSIONS
Our results can help studies assess generalizability, set targets for recruitment, or reweigh data to reflect U.S. averages.
