YSDSWRK: YOUTH: MDE ROLE IMPAIRMENT - SCHOOL OR WORK

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:  Starting with the 2004 NSDUH, respondents were
administered separate age-appropriate depression modules
designed to measure whether or not respondents had
experienced a major depressive episode (MDE) in their
lifetime and past year. All adolescent (youth) respondents
aged 12 to 17 were asked questions from the Youth Depression
module. The 2004 NSDUH only asked a subsample of adults aged
18 or older the questions from the Adult Depression module,
but starting in 2005, all adults were administered the
questionnaire module.

From 2004 through 2007, a single set of variables was
created containing the recoded MDE data for both adult and
adolescent respondents combined. In 2008, instead of a
single set of variables, two recoded sets of MDE variables
were created for adolescents and adults separately. This
change was due to the presence of context effects in the
adult estimates stemming from changes in the mental health
module which precedes the adult depression section within
the questionnaire. Based on an analysis of the 2008 data
that evaluated the presence of context effects, it was
determined that the adult depression estimates in 2008 and
later years are not comparable with years prior to 2008, and
the variables were therefore renamed to indicate the lack of
comparability. The youth depression estimates were not
impacted by the 2008 adult questionnaire changes and are
considered comparable across years. However, despite
remaining comparable to prior years, the variables that
shared the same variable names for both youth and adult
depression data were assigned new names in 2008 since the
adult data were no longer comparable with prior data. These
renamed youth variables can be used in comparison or
analyses with data prior to 2008 by renaming the recoded
adolescent depression variables the same across all the
years. Youth depression variables that did not require
renaming are noted specifically in the comments above the
variables below. See the 2008 Recoded Mental Health Module
Variable Documentation Appendix for more detailed
information on the 2008 changes.

In 2009, changes were made to the youth mental health
service utilization (YMHSU) questions that preceded the
adolescent depression questions. These changes included the
replacement of five questions that asked about receipt of
special education services and school counseling, and time
spent in jail or foster care with questions that asked about
receipt of mental health services in the education and
justice system sectors. Due to this change, a context effect
analysis was done using data from the first 6 months of the
2009 NSDUH and sought to determine whether changes in the

YMHSU module affected responses to the first three
adolescent depression questions and the lifetime and past
year MDE estimates. The results of the analysis showed these
changes in 2009 did not appear to affect the estimates of
adolescent MDE; therefore, no further variable changes were
needed.

Additional details on these adolescent depression recoded
variables as well as sample SAS code showing how to rename
the variables for multi-year analyses are provided in the
Recoded Depression Variable Documentation Appendix.

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).

NOTE:  The following five variables were not renamed in 2008
since they were originally only defined for youth;
therefore, no changes are needed for these in order to
generate analyses across years.

NOTE:  The following four variables make up the four role
domains (chores at home, school or work, close relationships
with family, and social life) of the Sheehan Disability
Scale (SDS), which measures the impact of a disorder on an
adolescent's life.
