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 2011-2012 and the 2012-2013 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.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Average annual initiation of marijuana (%) = 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 individuals 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 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Illicit Drugs Other Than Marijuana include 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.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 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 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Tobacco Products include cigarettes, smokeless tobacco (i.e., chewing tobacco or snuff), cigars, or pipe tobacco.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 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.
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 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 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.
NOTE: Dependence is based on the definition found in the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).

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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the 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.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 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 2011-2012 and the 2012-2013 estimates. The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Needing But Not Receiving Treatment refers to respondents classified as needing treatment for alcohol, but not receiving treatment for an alcohol problem at a specialty facility (i.e., drug and alcohol rehabilitation facilities [inpatient or outpatient], hospitals [inpatient only], and mental health centers).
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.10 level.

The "Total U.S." estimates, along with the p values, are based on design-based (direct) estimation methods.
NOTE: Serious mental illness (SMI) is defined as having a diagnosable mental, behavioral, or emotional disorder, other than a developmental or substance use disorder, as assessed by the Mental Health Surveillance Study (MHSS) Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders—Fourth Edition—Research Version—Axis I Disorders (MHSS-SCID), which is based on the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). SMI includes individuals with diagnoses resulting in serious functional impairment.

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 2011-2012 and the 2012-2013 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 B of the "2011-2012 NSDUH: Guide to State Tables and Summary of Small Area Estimation Methodology" at http://www.samhsa.gov/data/population-data-nsduh/reports?tab=33.
NOTE: There are minor wording differences in the questions in the adult and adolescent MDE modules. Therefore, data from youths aged 12 to 17 were not combined with data from adults aged 18 or older to produce an estimate for those aged 12 or older.
a Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.05 level.
b Difference between the 2011-2012 estimate and the 2012-2013 estimate is statistically significant at the 0.10 level.

Methodology Used to Estimate the Bayes
Posterior Probability of No Change between the
2011-2012 and 2012-2013 Small Area Estimates

Comparisons between State small area estimates displayed in Tables 1 to 26 in this document are based on the 2011 through 2013 National Surveys on Drug Use and Health (NSDUHs). The moving average State estimates for the overlapping 2011-2012 and 2012-2013 time periods were obtained from independent applications of the survey-weighted hierarchical Bayes (SWHB) methodology; that is, the 2012-2013 models were fit independently of the previously fitted 2011-2012 models. This independent analysis approach was followed because there was no desire to revise the previously published 2011-2012 estimates. Moreover, the same fixed predictor variables were used in the 2011-2012 and 2012-2013 models, but annual updates were made when more current versions became available.1 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 the 2011-2012 and 2012-2013 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 2012-2013 and 2011-2012 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 = 0). An estimate of lor sub s and a is given by

Equation 2,     D

where the p 1 sub s and a are previously published 2011-2012 State estimates and the p 2 sub s and a are the 2012-2013 State estimates. To compute the variance of the 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 2011-2012 Bayesian confidence intervals and the 2012-2013 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 2011, 2012, and 2013 NSDUH data. This simultaneous modeling approach was adopted based on the results of the validation study2 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 (2011, 2012, and 2013), 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 the natural logarithm of pi 1 sub s and a divided by 1 minus pi 1 sub s and a and the 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.

Long description, Equation 2. The estimate of the log-odds ratio, lor hat sub s and a, is defined as the natural logarithm of the ratio of two quantities. The numerator of the ratio is p 2 sub s and a divided by 1 minus p 2 sub s and a. The denominator of the ratio is p 1 sub s and a divided by 1 minus p 1 sub s and a, where p 1 sub s and a are the 2011-2012 State estimates and p 2 sub s and a are the 2012-2013 State estimates.

Long description end. Return to Equation 2.

Long description, Equation 3. Variance v of the estimate of the log-odds ratio, lor hat sub s and a, is a function of three quantities: q1, q2, and q3. It is expressed as the sum of q1 and q2 minus q3. Quantity q1 is the variance v of the natural logarithm of Theta 1 hat, quantity q2 is the variance v of the natural logarithm of Theta 2 hat, and quantity q3 is 2 times the covariance between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat.

Long description end. Return to Equation 3.

Long description, Equation 4. The covariance between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat is equal to the correlation between the natural logarithm of Theta 1 hat and the natural logarithm of Theta 2 hat multiplied by the square root of the product of the variance v of the natural logarithm of Theta 1 hat and variance v of the natural logarithm of Theta 2 hat.
