MDEIMPY: YOUTH: MDE WITH SEVERE ROLE IMPAIRMENT
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 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. 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)||1,051||1.8%|
|2||No (YMDEYR=2 or YSDSOVRL=1,2,3)||16,920||29.5%|
|-9||Aged 18+/Unknown (Otherwise)||39,342||68.6%|
