The Drug Use Questionnaire (variable name prefix DUQ) focuses on lifetime and current use of marijuana or hashish, cocaine, heroin, and methamphetamine, as well as intravenous use of these and other drugs.
Participants aged 12-69 years were eligible; however, only data from participants aged 12-17 are included in this file with limited access through the NCHS Research Data Center (RDC). Data from participants aged 18-69 are publically released in a separate file and available on the NHANES website. Mentally impaired participants, or participants who were unable to understand English, Spanish, Korean, Vietnamese, or Chinese (traditional/mandarin, simplified/mandarin, and traditional/Cantonese) were excluded from the DUQ.
The DUQ was administered at the Mobile Examination Center (MEC) during the MEC Interview. For youths aged 12-17, questions were self-administered using the Audio Computer-Assisted Self-Interview (ACASI) system.
The ACASI was conducted in one of the following languages: English, Spanish, Korean, Vietnamese, or Chinese (traditional/mandarin, simplified/mandarin, and traditional/Cantonese).
The ACASI enables respondents to hear questions through headphones as well as read questions on the computer screen. Respondents moved at their own speed and touched the screen to indicate their responses. No proxy respondents or translators were used during the ACASI.
For details on the QA/QC process for this component, please refer to the MEC Interviewer Procedures manual on the NHANES website.
The data were edited for completeness, consistency, and illogical values.
Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues.
Information on drug use is collected from all participants aged 12-69 years. Only data from participants aged 12-17 are included in this file with limited access. Data from participants aged 18-69 are publicly released and available on the NHANES website.
