This short report summarizes the type of national-, State-, and substate-level publications and methodologies using National Survey on Drug Use and Health (NSDUH). Information on accessing the NSDUH public-use file (PUF), the restricted-use data analysis system (R-DAS), and other future NSDUH data access options are discussed.

Learn how to produce basic estimates with the 2021 National Survey on Drug Use and Health (NSDUH). The report describes the techniques that were used to make the 2021 NSDUH Detailed Tables and the 2021 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.

Learn about the sample design used for the 2023 National Survey on Drug Use and Health (NSDUH). The report describes the five stages of sample selection, sample weighting and variance estimation procedures, and the Mental Illness Calibration Study sample design.Chapters:Introduces the report, describes the target population, and provides a general overview of the 2023 NSDUH sample design.Summarizes the 2014 through 2023 coordinated sample design.Discusses the first three stages of selection in greater detail.Describes the 2023 NSDUH hybrid field enumeration and address-based sampling frame.Discusses the fourth and fifth stages of selection.Describes sample weighting and variance estimation procedures for 2023.Summarizes the sample design for the Mental Illness Calibration Study.

Explore the data quality of the 2014-2019 National Survey on Drug Use and Health (NSDUH) Public Use Files (PUFs) and its comparability with the NSDUH Restricted Use Files (RUFs). This report demonstrates the overall quality of the NSDUH PUFs and the statistical disclosure control techniques used to create them.Chapters:Describes NSDUH and lays out the objective of the report.Presents an overview of the NSDUH disclosure concerns, briefly discusses the disclosure technique known as Micro Agglomeration, Substitution, Subsampling, and Calibration (MASSC), and provides a summary of this study’s quality assessment and research methods.Discusses how some of the detailed tables based on RUF data were selected and replicated using PUF data.Describes the data quality assessment results and findings.Summarizes the conclusions.There are also five appendices that support the analysis further.Aprevious reportanalyzed the PUF data from 2002-2013.

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.

This report describes the supplemental Mental Health Surveillance Study data collection to the 2011 National Survey on Drug Use and Health (NSDUH).

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.

This report describes the design and estimation procedures to the supplemental Mental Health Surveillance Study data collection to the 2011 National Survey on Drug Use and Health (NSDUH).

Use this summary report to properly interpret 2021 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 2021 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. The report also includes methodological changes and related issues in the 2021 NSDUH due to COVID-19.Technical details on the statistical methods and measurement, such as suppression criteria for unreliable estimates, statistical testing procedures, issues around selected substance use and mental health measures, and the impact of methodological changes on response rates.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 2021 NSDUH, including the results of special analyses that led SAMHSA to not compare estimates from 2021 to estimates from previous years.An appendix covers key definitions used in NSDUH reports and tables.

This report provides a guide to the development and presentation of the 2013-2014 NSDUH State estimates. A summary of the methodology is included along with tables containing sample sizes, response rates, and population estimates (i.e., denominators of percentages) by State and age group.
