ALQY_F

Component Description

The alcohol use (ALQ) questions focus on lifetime and current use (past 12 months). Questions are not specific to type of alcohol used.

Eligible Sample

Participants aged 12 years and older were eligible. Only data from participants aged 12-17 years old are included in this file with limited access.

Interview Setting and Mode of Administration

The Alcohol questionnaire is administered at the Mobile Examination Center (MEC) during the MEC Interview. For Youths 12-19 years, questions were self-administered using the Audio Computer-Assisted Self-Interviewing – ACASI system, The ACASI was conducted in either English or Spanish. The ACASI enables respondents to hear questions through earphones as well as read questions on the computer screen. Respondents move at their own speed and touch the screen to indicate their response. No proxy respondents or translators were used in situations when the respondents could not self-report.

Mentally impaired individuals or participants who were unable to understand English or Spanish were not asked these questions.

Quality Assurance & Quality Control

For details on the QA/QC process for this component, please refer to the MEC Interview 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 years old are included in this file with limited access. Data from participants aged 20 years and older as well as youth 18-19 years are publicly released in two separate files (i.e., ALQ_F and ALQY_F) available on the NHANES website.
