Results from the 2010 National Survey on Drug Use and Health: Mental Health Detailed Tables is a collection of tables presenting national estimates from the National Survey on Drug Use and Health (NSDUH). These tables present information on past year mental health measures and past year mental health service utilization for youths aged 12 to 17 and adults aged 18 or older. Adult tables include measures on any mental illness, serious mental illness (SMI), moderate mental illness, low (mild) mental illness, mental health service utilization (i.e., mental health treatment or counseling), suicidal thoughts and behaviors, major depressive episode (MDE), treatment for depression (among adults with MDE), and serious psychological distress (SPD). Youth tables include measures on mental health service utilization, MDE, and treatment for depression (among youths with MDE). Measures related to the co-occurrence of mental disorders with substance use or with substance use disorders also are presented for both adults and youths. Measures of these characteristics and behaviors are presented by a variety of demographic, geographic, and other variables. The estimates in the tables include rates of persons having the characteristics, numbers of persons with these characteristics, and other measures.
The majority of these tables are trend tables presenting estimates from the 2009 and 2010 NSDUHs. Also included are five tables that present data from earlier surveys in the series, including two tables with data from 2002 to 2010, two tables with data from 2005 to 2010, and one table with data from 2004 to 2010.
Throughout the survey series, the NSDUH questionnaire has been used to collect data on special topics, such as mental health. Questions on mental health for youths (aged 12 to 17) and adults (aged 18 or older) were first introduced in the 1994 NSDUH and continued through the 1997 NSDUH. Mental health questions were reintroduced beginning in the 2000 NSDUH and continued through the 2010 NSDUH. Because of survey improvements in the 2002 NSDUH, the 2002 data constitute a new baseline for tracking trends in substance use and mental health measures. Therefore, estimates beginning with the 2002 survey should not be compared with estimates from the 2001 or earlier surveys to examine changes over time. Because of further survey improvements and questionnaire changes between 2002 and 2010, it is not possible to assess long-term trends for all of the mental health issues.
Revisions were made to the mental health module in the 2008 NSDUH questionnaire, which resulted in new estimates for adults aged 18 or older (SMI, 30-day SPD, and suicidal thoughts and behavior). The new SMI estimates are not comparable with SMI estimates produced from NSDUH data prior to 2004, and SMI estimates were not produced from 2004 through 2007; thus, long-term trend estimates are not available for SMI. Because of the 2008 questionnaire revisions, several estimates (MDE and 12-month SPD) were affected by context effects. However, an adjustment for the questionnaire changes was applied to estimates of MDE for 2005 to 2007. For more detailed information, see Section B.4.4 in Appendix B of the Results from the 2010 National Survey on Drug Use and Health: Mental Health Findings.1 Therefore, long-term trend estimates for these two measures are available from 2005 through 2010. There were no additional questionnaire changes in 2009 or 2010 that led to changes in these adult measures. No questionnaire changes have been implemented that affected the adult mental health service utilization questions; therefore, estimates of mental health service utilization presented in these mental health detailed tables reflect trends from 2002 to 2010.
There were no questionnaire revisions that affected MDE for youths aged 12 to 17; thus, long-term trend estimates are available from 2004 through 2010. However, revisions to the youth mental health service utilization module of the 2009 NSDUH questionnaire resulted in new estimates and a discontinuation of trends for several items on the source of mental health services. New questions regarding the receipt of mental health services from juvenile justice sources were added, and questions regarding services from educational sources were revised and are not comparable with estimates prior to 2009.
For detailed information on revisions to both the adult and the youth mental health items, see Sections B.4.2 to B.4.4 in Appendix B of the Results from the 2010 National Survey on Drug Use and Health: Mental Health Findings.2
A description of the survey measurement issues and the sample design and estimation procedures used in the 2010 NSDUH can be found in technical appendices within that same report. Definitions for many of the measures and terms used in these mental health detailed tables and in the mental health national findings report can be located in the glossary that is provided with these mental health detailed tables.3 Where relevant, the glossary provides cross-references between terms and specific question wording for clarity.
The mental health detailed tables are numbered using a three-part numbering scheme (e.g., 1.21A). The first part of the table number (1.21A) is the subject matter section to which a particular table belongs. The second part (1.21A) is the number of the table within a particular section. The third part (1.21A) is a table type indicator, an alphabetic letter appended to the table number. Each table number, as explained below, has multiple table types. Tables are numbered sequentially within each subject matter section. To the extent possible, identical tables are assigned the same table number each year except in the case where specific tables are removed or added.
The three subject matter sections and the number of tables per section are as follows:
Section 1: Adult Mental Health Tables - 1.1 to 1.65
Section 2: Youth Mental Health Tables - 2.1 to 2.14
Section 3: Sample Size and Population Tables - 3.1 to 3.8
The table type indicators are defined as follows:
|Table Type||Purpose of the Table|
|A:||Presents estimates of the numbers of persons exhibiting the specified behavior or characteristic (e.g., substance use) in the populations described by the column and row headings.|
|B:||Presents estimates of the percentages of persons exhibiting the specified behavior or characteristic (e.g., substance use) in the populations described by the column and row headings.|
|C:||Presents the standard error associated with each of the estimates in the "A" tables.|
|D:||Presents the standard error associated with each of the estimates in the "B" tables.|
|N:||Presents the number of cases in the specified NSDUH sample with the characteristics defined by the column and row headings.|
|P:||Presents the p values from tests of the statistical significance of differences between columns in the "B" tables.|
Section 1 and Section 2 tables within the mental health detailed tables contain five table types (A, B, C, D, and P) as defined above. Section 3 tables contain three table types (A, C, and N). Note that table type N is used exclusively within Section 3 to display the sample size counts.
The mental health detailed tables are organized by table type into two categories:
Both categories are organized based on three subject matter sections as listed below. Clicking on the subject matter section of interest takes users to a list of tables for that section. Users can scroll through the list of table titles to find the table of interest, then click on the table title to go directly to that table. Users need to return to the table of contents to access tables from other sections or categories.
The "Key Definitions for the 2010 Mental Health Detailed Tables and Mental Health Findings Report" (i.e., the glossary) defines and cross-references key measures used in the 2010 mental health detailed tables and the 2010 mental health findings report. This may be helpful when used in conjunction with the list of tables in identifying tables that contain information for selected measures. However, not all measures and terms listed in the glossary are specifically mentioned in the table index or list of tables.
The three subject matter sections are as follows:
Section 1: Adult Mental Health Tables
Section 2: Youth Mental Health Tables
Section 3: Sample Size and Population Tables
