Component Description

The Drug use questions (DUQ) focused on lifetime and current use of cocaine and other street drugs, as well as intravenous use of drugs.

Eligible Sample

20 – 59 years.

Interview Setting and Mode of Administration

MEC Interview Room, Mobile examination Center.

Audio computer assisted self interview (ACASI) in English or Spanish only.

No proxy respondents or translators were used in situations when the respondents could not self-report.

Quality Assurance & Quality Control

ACASI software included consistency checks, including range checks, valid response checks, and checks for logical relationships. Soft edits alerted respondents to a potential error or problems, but allowed the respondents to proceed after confirming that the entry was correct. Hard edits prohibited the respondents from continuing with the ACASI until the error was corrected.

Data Processing and Editing

Data for participants aged 12-19 years are not included in this release due to confidentiality concerns. However special use data files for this age group are available through the NCHS Research Data Center.
