I am working with the National Comorbidity Survey Replication (NCS-R) and I want to know the exact sampling method, universe eligibility, etc. for the following items:

TB15L: Self report of tobacco as causation of emotional problems SC21, SC22, SC23: Variables related to depression DA31B_101: Religious preference DA40: Age of mother when you were born PEA52: Personality question - “I often feel empty inside"


The User Guide on the CPES website has a lengthy description of the sampling frame used by NCS-R:

The interactive documentation will report the universe for each of the variables you mention.
