Epidemiology Surveys

Are all questions asked of all respondents?

No. Some questions were asked in one study and not in the others. Questions not asked of all respondents include the following:
  • Age under 45: The Attention Deficit/Hyperactivity (AD), Oppositional Defiant Disorder (OD), and Conduct Disorder (CD) sections were administered only to individuals who were under the age of 45.
  • The National Comorbidity Survey Replication (NCS-R) had two Parts: Part 1 included a core diagnostic assessment of all 9,282 respondents. Part 2 was administered only to 5,692 of the 9,282 Part 1 respondents, including all Part 1 respondents with a lifetime disorder plus a probability subsample of other respondents. See the Final Weights section of the User Guide section of About CPES for an explanation of the two parts and the implications for weighting analyses.
  • The National Survey of American Life (NSAL) Black Caribbean sample had some questions that no one else had.
  • The National Survey of American Life (NSAL) had several sections which were not administered to the White sample. See below for a list of sections skipped if the NSAL respondent was White.
