NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Binge Alcohol Use is defined as drinking five or more drinks on the same occasion (i.e., at the same time or within a couple of hours of each other) on at least 1 day in the past 30 days.
a Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Binge Alcohol Use is defined as drinking five or more drinks on the same occasion (i.e., at the same time or within a couple hours of each other) on at least 1 day in the past 30 days.
a Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Dependence or abuse is based on definitions found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).
a Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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.
NOTE: Dependence or abuse is based on definitions found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).
a Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.

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 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Serious Mental Illness 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) and resulted in serious functional impairment. 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 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

NOTE: State and census region estimates are based on a survey-weighted hierarchical Bayes estimation approach, with their p values being the Bayes posterior probability of no change between the 2009-2010 and the 2010-2011 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
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.
NOTE: There are minor wording differences in the questions in the adult and adolescent major depressive episode modules. Therefore, data from youths aged 12 to 17 were not combined with data from persons aged 18 or older to produce an estimate for those aged 12 or older.
a Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.05 level.
b Difference between the 2009-2010 estimate and the 2010-2011 estimate is statistically significant at the 0.10 level.

Methodology Used to Estimate the Bayes Posterior Probability of No Change
between the 2009-2010 and 2010-2011 Small Area Estimates

Comparisons between State small area estimates displayed in Tables 1 to 26 in this document are based on the 2009 through 2011 National Surveys on Drug Use and Health (NSDUHs). The moving average State prevalence estimates for the overlapping 2009-2010 and 2010-2011 time periods were obtained from independent applications of the survey-weighted hierarchical Bayes (SWHB) methodology; that is, the 2010-2011 models were fit independently of the previously fitted 2009-2010 models. This independent analysis approach was followed because there was no desire to revise the previously published 2009-2010 estimates. Moreover, the same fixed predictor variables were used in the 2009-2010 and 2010-2011 models, but annual updates were made when more current versions became available (for details, see Section B.3 in the "2010-2011 National Survey on Drug Use and Health: Guide to State Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/NSDUH/2k11State/NSDUHsae2011/Index.aspx). The age group-specific fixed predictor variables were defined at five levels (namely, the person level, census block group level, tract level, county level, and State level). Also, each age group model had 51 State-level random effects and 300 "within-State" area-level random effects.

To estimate change in State estimates, let [pi 1 sub s and a] and [pi 2 sub s and a] denote 2009-2010 and 2010-2011 prevalence rates, respectively, for State-s and age group-a. The change between [pi 1 sub s and a] and [pi 2 sub s and a] is defined in terms of the log-odds ratio ([lor sub s and a]) as opposed to the simple difference because the posterior distribution of the [lor sub s and a] is closer to Gaussian than the posterior distribution of the simple difference ([Pi 2 sub s and a minus pi 1 sub s and a represents the simple difference between the 2010-2011 and 2009-2010 prevalence rates.]). The [lor sub s and a] is defined as

Equation 1,     D


where ln denotes the natural logarithm. The p value given is computed to test the null hypothesis of no change (i.e., [Pi 2 sub s and a is equal to pi 1 sub s and a] or equivalently, Log-odds ratio lor sub s and a is equal to zero). An estimate of [Log-odds ratio lor sub s and a] is given by

Equation 2,     D


where the [p 1 sub s and a] are previously published 2009-2010 State estimates and the [p 2 sub s and a] are the 2010-2011 State estimates. To compute the variance of [estimate of the log-odds ratio, lor hat sub s and a] that is, [variance v of the estimate of the log-odds ratio, lor hat sub s and a] let [Theta 1 hat equal the ratio of p 1 sub s and a and 1 minus p 1 sub s and a] and [Theta 2 hat equal the ratio of p 2 sub s and a and 1 minus p 2 sub s and a] then

Equation 3,     D

where [covariance between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat] denotes the covariance between [natural logarithm of Theta 1 hat] and [natural logarithm of Theta 2 hat]. This covariance is defined in terms of the associated correlation as follows:

Equation 4.     D

Note that [variance v of the natural logarithm of Theta 1 hat] and [variance v of the natural logarithm of Theta 2 hat] used here to calculate [variance v of the estimate of the log-odds ratio, lor hat sub s and a] are the same variances used in calculating the previously published 2009-2010 Bayesian confidence intervals and the 2010-2011 Bayesian confidence intervals, respectively.

The correlation between [natural logarithm of Theta 1 hat] and [natural logarithm of Theta 2 hat] was obtained by simultaneously modeling the 2009, 2010, and 2011 NSDUH data. This simultaneous modeling approach was adopted based on the results of the validation study1 conducted for measuring change in the 1999-2000 and 2000-2001 State estimates. For this simultaneous model, 4 age groups (12 to 17, 18 to 25, 26 to 34, and 35 or older) by 3 years (2009, 2010, and 2011), that is, 12 subpopulation-specific models, were fitted, each with its own set of fixed and random effects. In this case, the general covariance matrices for the State and within-State random effects were 12 × 12 matrices corresponding to the 12 element (age group × year) vectors of random effects. Note that the survey-weighted, Bernoulli-type log likelihood employed in the SWHB methodology was appropriate for this simultaneous model because the 12 age group × year subpopulations were nonoverlapping. The correlation [[natural logarithm of Theta 1 hat], [natural logarithm of Theta 2 hat]] was approximated by the correlation calculated using the posterior distributions of [natural logarithm of pi 1 sub s and a divided by 1 minus pi 1 sub s and a] and [natural logarithm of pi 2 sub s and a divided by 1 minus pi 2 sub s and a] from the simultaneous model.

To calculate the p value for testing the null hypothesis of no difference [Log-odds ratio lor is equal to zero], it is assumed that the posterior distribution of lor is normal with [Mean is equal to estimate of the log-odds ratio, lor hat sub s and a] and [Variance is equal to variance v of the estimate of the log-odds ratio, lor hat sub s and a]. With the null value of [Log-odds ratio lor is equal to zero], the Bayes p value or posterior probability of no difference is [The p value is equal to 2 times the probability of realizing a standard normal variate greater than or equal to the absolute value of a quantity z], where Z is a standard normal random variate, [Quantity z is the estimate of the log-odds ratio, lor hat sub s and a, divided by the square root of the variance v of the estimate of the log-odds ratio, lor hat sub s and a.] and [absolute value of quantity z] denotes the absolute value of z.
