Interview Setting and Mode of Administration

Mode of Administration

 MEC ACASI Interview

Data Collection Methods

The NHANES Audio Computer Assisted Self Interview (ACASI) was conducted in a private room in the MEC in either English or Spanish. The ACASI enabled the respondents both to hear questions through earphones and read questions on the computer and to move at their own speed as they touch the screen to indicate their response. No proxies or translators were permitted.

Data Processing and Editing

Responses to SXQ030 (age at first sex) between 1-9 years were recoded as "under 10 years."

 

Analytic Notes

 Special Notes on Using the Dataset

Wording of some of the questions differed slightly between the 1999 and 2000 surveys. In the 1999 household questionnaire the term "sexual intercourse" was used (instead of "sex") in the following questions: SXQ030, SXQ120, SXQ130, SXQ150, SXQ170, SXQ190, SXQ200, SXQ220.
