Revised Mental Illness Estimates: The Substance Abuse and Mental Health Services Administration (SAMHSA) has been publishing State estimates of the prevalence (both percentages and estimated counts) of past year serious mental illness (SMI) and any mental illness (AMI) among adults aged 18 or older since the release of the 2008-2009 State small area estimation (SAE) report. Estimates were based on a model developed in 2008. In 2013, SAMHSA developed a more accurate model for the 2012 data. This revised model incorporates the NSDUH respondent's age and indicators of past year suicide thoughts and depression, along with the variables that were specified in the 2008 model (Kessler-6 [K6] questions on psychological distress and an abbreviated set of questions on impairment in carrying out activities from the World Health Organization Disability Assessment Schedule [WHODAS]), leading to more accurate estimates of SMI and AMI. The SMI and AMI tables in this document include estimates that have been revised based on the new model. Other mental health measures in these tables, such as major depressive episode (MDE) and serious thoughts of suicide, were not affected. For further information on the revised model, see the NSDUH short report titled Revised Estimates of Mental Illness from the National Survey on Drug Use and Health at https://www.samhsa.gov/data.

| NOTE: State and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and p values, are based on design-based (direct) estimation methods. NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs). NOTE: Illicit Drugs include marijuana/hashish, cocaine (including crack), heroin, hallucinogens, inhalants, or prescription-type psychotherapeutics used nonmedically, including data from original methamphetamine questions but not including new methamphetamine items added in 2005 and 2006. See Section B.4.8 in Appendix B of the Results from the 2008 National Survey on Drug Use and Health: National Findings. a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level. b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

| NOTE: State and census region Bayesian confidence (credible) intervals presented above use a simultaneous solution for the First Use of Marijuana and Never Used Marijuana outcomes, which had age group-specific random effects that were allowed to be correlated across the two outcomes. The associated Markov Chain Monte Carlo chains were used to calculate the posterior variance. Their p values are the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and p values, are based on design-based (direct) estimation methods. NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs). NOTE: Average annual marijuana initiation rate = 100 × {[X1 ÷ (0.5 × X1 + X2)] ÷ 2}, where X1 is the number of marijuana initiates in the past 24 months and X2 is the number of persons who never used marijuana. Both of the computation components, X1 and X2, are based on a survey-weighted hierarchical Bayes estimation approach. Note that the age group is based on a respondent's age at the time of the interview, not his or her age at first use. a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level. b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

| NOTE: State and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and p values, are based on design-based (direct) estimation methods.

NOTE: Needing But Not Receiving Treatment refers to respondents classified as needing treatment for illicit drugs, but not receiving treatment for an illicit drug problem at a specialty facility (i.e., drug and alcohol rehabilitation facilities [inpatient or outpatient], hospitals [inpatient only], and mental health centers). Illicit Drugs include marijuana/hashish, cocaine (including crack), inhalants, hallucinogens, heroin, or prescription-type psychotherapeutics used nonmedically, including data from original methamphetamine questions but not including new methamphetamine items added in 2005 and 2006. See Section B.4.8 in Appendix B of the Results from the 2008 National Survey on Drug Use and Health: National Findings. a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level. b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

P Value |
|---|---|---|---|---|---|
| NOTE: State and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and p values, are based on design-based (direct) estimation methods. NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs). NOTE: Any mental illness (AMI) is defined as having a diagnosable mental, behavioral, or emotional disorder, other than a developmental or substance use disorder, that met the criteria found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Estimates for AMI presented in this table may differ from previously published AMI estimates because of revised estimation procedures. For details, see the NSDUH short report titled Revised Estimates of Mental Illness from the National Survey on Drug Use and Health at https://www.samhsa.gov/data. a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level. b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.

| NOTE: State and census region estimates, along with the 95 percent Bayesian confidence (credible) intervals, are based on a survey-weighted hierarchical Bayes estimation approach and are generated by Markov Chain Monte Carlo techniques, with their p values being the Bayes posterior probability of no change between the 2008-2009 and the 2009-2010 estimates. The "Total U.S." estimates, along with the 95 percent confidence intervals and p values, are based on design-based (direct) estimation methods. NOTE: The 2008-2009 estimates may differ from previously published estimates due to updates (see Section 1.5 of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs). NOTE: Major depressive episode (MDE) is defined as in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), which specifies a period of at least 2 weeks when a person experienced a depressed mood or loss of interest or pleasure in daily activities and had a majority of specified depression symptoms. For details, see Section A.11 in Appendix A of the report on State Estimates of Substance Use and Mental Disorders from the 2009-2010 NSDUHs. a Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.05 level. b Difference between the 2008-2009 estimate and the 2009-2010 estimate is statistically significant at the 0.10 level.
