GINET Internet Module

OVERVIEW 

The Internet module of the telephone interview includes items regarding the use
of personal computers and the Internet by the respondent and members of the
respondent's household.  Information about current or past household computer
ownership and current or past household Internet access is included in this
module.  Main topics of interest for respondents who have access to the
Internet from home include how long ago his or her household first got Internet
access, how much time he or she spends using the Internet from home, and
whether or not the respondent's spouse connects to the Internet from home.  To
gain a better understanding of why some respondents do not have a personal
computer or access to the Internet from home, some items within the module ask
the main reason why the respondent's household does not have these things.

Previous waves of the Wisconsin Longitudinal Study did not include an Internet
module.  Although computer networks similar to the Internet existed much
earlier, the public version of the Internet became available in the 1990's. At
the time of the 1993 WLS study, very few households had Internet access, and an
Internet module would have been impractical at that time.  As the Internet
continues to become a more popular tool for communication, entertainment,
financial management, and learning, understanding our respondents' computer and
Internet use trends can provide important insights about computer and Internet
use among the aging population.

In addition to obtaining information about computer and Internet use, the
Internet module will also be used as an experiment to test different wordings
of the same questions.  Five questions in this module have alternate wordings
and response choice orders.
