Use this summary report to properly interpret 2020 NSDUH estimates of substance use and mental health issues. The report accompanies theannual detailed tablesand covers overall methodology, key definitions for measures and terms used in 2020 NSDUH reports and tables, and selected analyses of the measures and how they should be interpreted.The report is organized into six chapters:Introduction.Description of the survey, including information about the sample design, data collection procedures, and key aspects of data processing such as development of the analysis weights.Technical details on the statistical methods and measurement, such as suppression criteria for unreliable estimates, statistical testing procedures, issues around data accuracy, and measurement issues for selected substance use and mental health measures.Special topics related to prescription psychotherapeutic drugs.A comparison between NSDUH and other sources of data on substance use and mental health issues, including data sources for populations outside the NSDUH target population.A more in-depth view of special methodological issues for the 2020 NSDUH, including those related to methodological changes made because of the Coronavirus 2019 Pandemic.An appendix covers key definitions used in NSDUH reports and tables.

This report summarizes the 2018 NSDUH methods and other supporting information relevant to estimates of substance use and mental health issues, and organized into five chapters. Chapter 1 is an introduction to the report. Chapter 2 describes the survey, including information about the sample design; data collection procedures; and key aspects of data processing, such as development of analysis weights. Chapter 3 presents technical details on the statistical methods and measurement, such as suppression criteria for unreliable estimates, statistical testing procedures, and issues for selected substance use and mental health measures. Chapter 4 covers special topics related to prescription psychotherapeutic drugs. Chapter 5 describes other sources of data on substance use and mental health issues, including data sources for populations outside the NSDUH target population. Appendix A is a glossary that covers key definitions for use as a resource with the 2018 NSDUH reports and detailed tables. Appendix B provides a list of contributors to the report.

The Annual Detailed Tables present in-depth findings on location, characteristics, and utilization of substance use and mental health services as collected by the National Substance Use and Mental Health Survey (N-SUMHSS). The data presented are intended to provide behavioral health services providers; researchers; and federal, state, and local governments with information about the number and characteristics of public and private substance use and mental health treatment facilities nationwide.

This report is organized into seven sections. Section A describes the survey, including information about the sample design, data collection procedures, and key aspects of data processing (e.g., development of analysis weights). Section B presents technical details on the statistical methods and measurement, such as suppression criteria for unreliable estimates, statistical testing procedures, and issues for selected substance use and mental health measures. Section C discusses special topics related to prescription psychotherapeutic drugs. A glossary that covers key definitions used in NSDUH reports and tables is included in Section D. Section E describes other sources of data on substance use and mental health issues, including data sources for populations outside the NSDUH target population. A list of references cited in the report (Section F) and a list of contributors to this report (Section G) also are provided.

This report describes the supplemental Mental Health Surveillance Study data collection to the 2012 National Survey on Drug Use and Health (NSDUH). The MHSS staffing, data collection procedures and materials, data collection staff training, response rates, and quality control procedures.

Learn how to produce basic estimates with the 2022 National Survey on Drug Use and Health (NSDUH). The report describes the techniques that were used to make the 2022 NSDUH Detailed Tables and the 2022 NSDUH Annual National Report, but users may also find these techniques useful for their own research with NSDUH. The report describes the calculation of estimates and sampling errors, degrees of freedom, and the procedures for determining when low-precision estimates should be suppressed. It also includes sample code in several statistical languages that data users can modify to use in their own research.Chapters:Introduction to the report.Background on the survey design, including redesign and questionnaire changes.Prevalence estimates and how they were calculated, including specifics on various topics presented in the detailed tables.Discussion of how missing item responses of variables that are not imputed may lead to biased estimates.Discussion of sampling errors and how they were calculated.Description of degrees of freedom and how they were used to compare estimates.Discussion of how the statistical significance of differences between estimates was determined.Discussion of confidence interval estimation.Discussion of when estimates with low precision were suppressed.Appendix A contains code samples for various statistical procedures documented within the report.

This report describes the design and estimation procedures to the supplemental Mental Health Surveillance Study (MHSS) data collection to the 2012 National Survey on Drug Use and Health (NSDUH). The report describes instruments used in measuring mental illness, sample design and selection (including the MHSS clinical sample characteristics), data collection and processing, weighting, nonresponse adjustment, and the development of the model for estimating mental illness.

Learn about all the data collection operations for the 2022 National Survey on Drug Use and Health (NSDUH). The report details the sampling, counting, and listing operations; field staffing and training; preparation of survey materials; data collection (both in-person and web); and quality control practices. It also includes information on the results of data collection, including detailed response rates.

This report describes the statistical inference procedures used to produce design-based estimates for the 2012 National Survey on Drug Use and Health (NSDUH). These design-based estimates are presented in the 2012 national findings report detailed tables, as well as the 2012 mental health findings report and detailed tables. The report covers missingness rates, sampling error, degrees of freedom, statistical significance differences, confidence intervals, incidence estimates, and suppression of estimates with low precision.
