Foreword

The Substance Abuse and Mental Health Services Administration (SAMHSA), an operating division within the U.S. 

Department of Health and Human Services (HHS), is charged with reducing the impact of substance abuse and 

mental illness on America’s communities. SAMHSA is pursuing this mission at a time of significant change. 

The Behavioral Health Barometer: California, Volume 6: Indicators as measured through the 2019 National Survey on 

Drug Use and Health and the National Survey of Substance Abuse Treatment Services is one of a series of national, 

regional, and state reports that provide a snapshot of behavioral health in the United States. The reports present a 

set of substance use and mental health indicators as measured through the National Survey on Drug Use and Health 

(NSDUH) and the National Survey of Substance Abuse Treatment Services (N–SSATS), sponsored by SAMHSA.

This array of indicators provides a unique overview of the nation’s behavioral health at a point in time as well as a 

mechanism for tracking changes over time. Behavioral Health Barometers for the nation, 10 regions, and all 50 states 

and the District of Columbia are published as part of SAMHSA’s behavioral health quality improvement approach. Most 

importantly, the Behavioral Health Barometers provide critical information in support of SAMHSA’s mission of reducing 

the impact of substance abuse and mental illness on America’s communities.

Introduction

Purpose of This Report 

Behavioral Health Barometer: California, Volume 6: Indicators as measured through the 2019 National Survey on 

Drug Use and Health and the National Survey of Substance Abuse Treatment Services provides an annual update on 

a series of topics that focus on substance use and mental health (collectively referred to as behavioral health) in the 

United States. SAMHSA selected specific topics and indicators in this report to represent a cross-section of the key 

behavioral health indicators that are assessed in SAMHSA data collections, including NSDUH and N–SSATS. This report 

is intended to provide a concise, reader-friendly summary of key behavioral health measures for lay and professional 

audiences. 

Organization of This Report

This report is divided into sections based on content areas and age groups. It begins with sections on substance 

use, mental health, and mental health treatment among youth aged 12–17, followed by a section on substance use 

and mental health among young adults aged 18–25. Next are sections on substance use, misuse, use disorders, and 

treatment among youth and adults combined and on mental health and treatment among adults aged 18 or older. 

Figure titles are included above all graphics, including callouts for figure notes that are presented on pages 34–35. 

These figure notes include additional information about the measures, populations, and analyses presented in the 

graphics and text. Definitions of key measures and terms included in the report are presented on pages 36–37. 

Methodological Information

Statistical tests (t-tests) have been conducted for all statements appearing in the text of the report based on NSDUH 

data that compare estimates between years or population subgroups. These tests properly account for the variances 

of each estimate being tested, as well as any joint variability (covariance) due to sample design or among nonmutually exclusive groups (e.g., each state is a subgroup of its respective region, and each region is a subgroup 

of the total United States). Positive covariance reduces the overall variance of the test statistic and may produce 

statistically significant results, even when the confidence intervals of each estimate overlap. Unless explicitly stated 

that a difference is not statistically significant, all statements based on NSDUH data that describe differences are 

significant at the .05 level. Standard NSDUH suppression rules have been applied for all NSDUH estimates in this 

report. Pages 27–30 present N–SSATS data, and because N–SSATS provides counts of people enrolled at all treatment 

facilities (as opposed to providing estimates based on a sample of treatment facilities), conducting significance tests 

is not necessary. Tables that display all data points included in this report, including tests of statistical significance and 

standard errors, are available upon request. To request these tables or to ask any questions regarding how to use or 

interpret the data included in this report, please contact CBHSQRequest@samhsa.hhs.gov.

Figure Notes

1 Estimates are annual averages based on combined 2017–2019 NSDUH data or NSDUH data for other combined 

years as indicated. 

2 Respondents with unknown past-year major depressive episode (MDE) data were excluded. 

3 Respondents with unknown past-year MDE or unknown treatment data were excluded. 

4 Consistent with federal definitions and other federal data collections, the NSDUH definition for binge alcohol use 

since 2015 differs for males and females. Thus, this indicator is based only on the 2015–2019 NSDUH data. Binge 

drinking for males is defined as drinking five or more drinks on the same occasion on at least 1 day in the past 

30 days, which is unchanged from the threshold prior to 2015. Since 2015, binge alcohol use for females has been 

defined as drinking four or more drinks on the same occasion on at least 1 day in the past 30 days. 

5 Estimates were based only on responses to suicidality items in the NSDUH Mental Health module. Respondents 

with unknown suicidality information were excluded. 

6 For further information, see The NSDUH Report: Revised Estimates of Mental Illness from the National Survey on 

Drug Use and Health, which is available on the SAMHSA website at https://www.samhsa.gov/data/sites/default/

files/NSDUH148/NSDUH148/sr148-mental-illness-estimates.pdf.

7 Significance testing was not conducted on these data. Conducting statistical significance tests is not necessary 

because these are counts of people enrolled at all treatment facilities (rather than estimates from a sample of 

treatment facilities).

8 Single-day counts reflect the number of individuals who were enrolled in substance use treatment on the last 

business day in March: March 31, 2015; March 31, 2016; March 31, 2017; and March 29, 2019. Single-day counts 

of the number of individuals enrolled in substance use treatment were not included in the 2018 National Survey of 

Substance Abuse Treatment Services (N–SSATS).

9 Enrollees whose substances were unknown were excluded. 

10 These counts reflect only individuals who were receiving these specific medication-assisted therapies (MATs) as 

part of their opioid treatment in specialty substance abuse treatment programs; they do not include counts of 

individuals who were receiving other types of treatment (such as those who received MAT from private physicians) 

for their opioid addiction on the reference dates.

11 Physicians who obtain specialized training per the Drug Addiction Treatment Act of 2000 (DATA 2000) may 

prescribe buprenorphine to treat opioid addiction. Some physicians are in private, office-based practices; others 

are affiliated with substance abuse treatment facilities or programs and may prescribe buprenorphine to clients at 

those facilities. Additionally, opioid treatment programs (OTPs) may also prescribe and/or dispense buprenorphine. 

The buprenorphine single-day counts include only those clients who received/were prescribed buprenorphine by 

physicians affiliated with substance abuse treatment facilities; they do not include clients from private practice 

physicians.

12 Respondents were not to include treatment for drug or alcohol use. Respondents with unknown service use 

information were excluded. Estimates were based only on responses to items in the NSDUH Adult Mental Health 

Service Utilization module.

Definitions

Alcohol use disorder and illicit drug use disorder are defined using diagnostic criteria specified within the 

Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), which include such symptoms as 

withdrawal, tolerance, use in dangerous situations, trouble with the law, and interference with major obligations at 

work, school, or home during the past year. For details, see American Psychiatric Association (1994). 

Any mental illness (AMI) is defined in NSDUH as adults aged 18 or older who currently or at any time in the past 

year have had a diagnosable mental, behavioral, or emotional disorder (excluding developmental and substance use 

disorders) of sufficient duration to meet DSM-IV criteria. AMI estimates are based on a predictive model applied to 

NSDUH data and are not direct measures of diagnostic status. Adults estimated as having a diagnosable mental, 

behavioral, or emotional disorder in the past year, regardless of their level of functional impairment, were defined as 

having AMI. 

Depression care is defined as seeing or talking to a medical doctor or other professional or using prescription 

medication for depression in the past year.

Major depressive episode (MDE) is defined as in the Diagnostic and Statistical Manual of Mental Disorders, Fifth 

Edition (DSM-5), which specifies a period of at least 2 weeks in the past year when an individual experienced a 

depressed mood or loss of interest or pleasure in daily activities and had a majority of specified depression symptoms. 

For details, see American Psychiatric Association (2013).

Marijuana use disorder is defined using diagnostic criteria specified within the DSM-IV (APA, 1994), which 

include such symptoms as tolerance, use in dangerous situations, trouble with the law, and interference with major 

obligations at work, school, or home during the past year.

Mental health service use is defined in the National Survey on Drug Use and Health (NSDUH) for adults aged 18 or 

older as receiving treatment or counseling for any problem with emotions, nerves, or mental health in the 12 months 

before the interview in any inpatient or outpatient setting, or the use of prescription medication for treatment of any 

mental or emotional condition that was not caused by the use of alcohol or drugs. 

Number of individuals enrolled in substance use treatment refers to the number of clients in treatment at 

alcohol and drug abuse facilities (public and private) throughout the 50 states, the District of Columbia, and other 

U.S. jurisdictions.

Opioid use disorder is defined as heroin use disorder or prescription pain reliever use disorder using diagnostic 

criteria specified within the DSM-IV (APA, 1994), which include such symptoms as withdrawal, tolerance, use in 

dangerous situations, trouble with the law, and interference with major obligations at work, school, or home during 

the past year.

Definitions

Prescription pain relievers include the following subcategories of pain relievers (examples of specific pain relievers 

shown in parentheses): hydrocodone products (e.g., Vicodin®, Lortab®, Norco®, Zohydro® ER, generic hydrocodone); 

oxycodone products (e.g., OxyContin®, Percocet®, Percodan®, Roxicodone®, generic oxycodone); tramadol products

(e.g., Ultram®, Ultram® ER, Ultracet®, generic tramadol, generic extended-release tramadol); codeine products

(e.g., Tylenol® with codeine 3 or 4, generic codeine pills); morphine products (e.g., Avinza®, Kadian®, MS Contin®, 

generic morphine, generic extended-release morphine); fentanyl products (e.g., Duragesic®, Fentora®, generic 

fentanyl); buprenorphine products (e.g., Suboxone®, generic buprenorphine, generic buprenorphine plus naloxone); 

oxymorphone products (e.g., Opana®, Opana® ER, generic oxymorphone, generic extended-release oxymorphone); 

Demerol®; hydromorphone products (e.g., Dilaudid® or generic hydromorphone, Exalgo® or generic extended-release 

hydromorphone); methadone; or any other prescription pain reliever. 

Prescription pain reliever misuse is defined as prescription pain reliever use in any way not directed by a doctor, 

including use without a prescription of one’s own; use in greater amounts, more often, or longer than told; or use in 

any other way not directed by a doctor.

Serious mental illness (SMI) is defined in NSDUH as adults aged 18 or older who currently or at any time in the 

past year have had a diagnosable mental, behavioral, or emotional disorder (excluding developmental and substance 

use disorders) of sufficient duration to meet diagnostic criteria specified in the DSM-IV and has resulted in serious 

functional impairment, which substantially interferes with or limits one or more major life activities. SMI estimates are 

based on a predictive model applied to NSDUH data and are not direct measures of diagnostic status. The estimation 

of SMI covers any mental disorders that result in serious impairment in functioning such as major depression and 

bipolar disorders. However, NSDUH data cannot be used to estimate the prevalence of specific mental disorders in 

adults. Also, it should be noted that SAMHSA has recently updated the definition of SMI for use in mental health block 

grants to include mental disorders as specified in the DSM-IV (APA, 1994).

Substance use disorder is defined as dependence on or abuse of alcohol, illicit drugs (e.g., marijuana, cocaine, 

hallucinogens, heroin, or inhalants), or psychotherapeutics (e.g., prescription pain relievers, sedatives, tranquilizers, 

or stimulants) in the past 12 months based on assessments of individual diagnostic criteria from the DSM-IV (APA, 

1994), which include such symptoms as withdrawal, tolerance, use in dangerous situations, trouble with the law, and 

interference with major obligations at work, school, or home during the past year.

The National Survey on Drug Use and Health (NSDUH) is an annual survey sponsored by the Substance Abuse 

and Mental Health Services Administration (SAMHSA). NSDUH is the primary source of information on the use of 

illicit drugs, alcohol, and tobacco in the U.S. civilian, noninstitutionalized population aged 12 years or older and 

includes mental health issues and mental health service utilization for adolescents aged 12–17 and adults aged 18 

or older. Conducted by the federal government since 1971, NSDUH collects data by administering questionnaires to 

a representative sample of the population through face-to-face interviews at their place of residence. The data used 

in this report are based on information obtained from approximately 67,500 individuals aged 12 years or older per 

year in the United States. Additional information about NSDUH is available at https://www.samhsa.gov/data/data-wecollect/nsduh-national-survey-drug-use-and-health. 

The National Survey of Substance Abuse Treatment Services (N–SSATS) is an annual census designed to collect 

information from all public and private treatment facilities in the United States that provide substance abuse 

treatment. The objectives of N–SSATS are to collect multipurpose data that can be used to assist SAMHSA and state 

and local governments in assessing the nature and extent of services provided and in forecasting treatment resource 

requirements, to update SAMHSA’s Inventory of Behavioral Health Services, to analyze general treatment services 

trends, and to generate the Behavioral Health Treatment Services Locator (https://findtreatment.samhsa.gov/). Data 

presented in this report reflect all publicly available data in N–SSATS reports at the time of the writing of this report 

and may present data previously unavailable in prior barometer reports. Additional information about N–SSATS is
