NOTE: The variables in this section are recoded variables that
were created from one or more of the edited variables from
the preceding section.

The youth activity questions in the 2001 NHSDA differ from those
in the 2000 NHSDA. The following variable, YTHACT2 was created by
counting the number of positive responses reported over the
following 4 youth activity questions: School-based (YESCHACT),
community-based (YECOMACT), church or faith-based (YEFAIACT), or
other activities (YEOTHACT). Youth respondents who reported
participation in 2 or more activities were included in the two or
more category regardless of how many other activity questions
were answered. Youth respondents who did not answer 2 or more
of the 4 youth activity questions with a "yes" or "no" response
were coded as SAS missing. To be included in the zero or one
category, a youth respondent must have answered 2 or more of the
activity questions and reported they participated in either zero
or one activity. YTHACT2 is not considered comparable with
YOUTHACT from the 2000 NHSDA.
