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

NOTE:  The following 22 variables are among all adolescent
respondents who were asked the respective questions and are
not confined to those respondents who were ultimately
classified as having a Major Depressive Episode (MDE) in
their lifetime or past year.  To produce estimates among
adolescents with MDE, the analysis will need to be
restricted by either the lifetime MDE variable (YMDELT) or
the past year MDE variable (YMDEYR).

The following variable, MDEIMPY, is derived from the maximum
severity level of MDE role impairment (YSDSOVRL) and is
restricted to adolescents with past year MDE (YMDEYR).
1 Yes (YMDEYR=1 and YSDSOVRL=4,5) 1,0661.9%
2 No (YMDEYR=2 or YSDSOVRL=1,2,3) 16,09429.1%
Missing Data
-9 Aged 18+/Unknown (Otherwise) 38,07468.9%
Total 55,234 100%

Based upon 17,160 valid cases out of 55,234 total cases.
