NAHDAP released the PATH Study Wave 2 Public-Use Files on June 14, 2017. These data are available for download at https://doi.org/10.3886/ICPSR36498 .
Specifically, the Wave 2 data files, questionnaires, and codebooks were added to the study collection. Also, the Master Linkage data file was added to facilitate merging respondent records across waves. The User Guide and Master Tobacco Brand and Product Code Guide were expanded to include information about Wave 2 and how to analyze the data longitudinally. The Wave 1 data files were updated to correct minor errors along with the questionnaires to correct minor typos and clarify specifications.
