Recoded Variables

Certain variables were categorized and recoded so that details possibly leading to identifying an individual research subject would be less likely to do so. Other variables were recoded to harmonize data across the three CPES studies--NCS-R, NLAAS, and NSAL. Recoded variables are listed in the following table, which shows the CPES variable label and study variable names, their original codes and labels, and their recode values and labels.
