Component Description

The Alcohol Use Questionnaire (variable name prefix ALQ) focuses on lifetime and recent use (past 30 days). Questions are not specific to type of alcohol used.

Eligible Sample

Participants aged 12-17 years only are included in this file with limited access. Mentally impaired individuals or participants who were unable to understand English or Spanish were excluded from these questions.

Interview Setting and Mode of Administration

Questions were self-administered using the Audio Computer-Assisted Self-Interview (ACASI) system. The ACASI was conducted in both English and Spanish.

Quality Assurance & Quality Control

The ACASI enables participants to hear questions through headphones as well as read questions on the computer screen. Participants moved at their own speeds 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.

Data Processing and Editing

The data were edited for completeness, consistency, and illogical values.

Analytic Notes

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 alcohol use is collected from all participants aged 12 years and older. Only data from participants aged 12-17 are included in this file with limited access. Data from participants aged 18 years and older is publicly released as ALQ_I and available on the NHANES website.
