This report compares the estimated (or realized) precisions of a key set of estimates with the targets for the 2012 National Survey on Drug Use and Health (NSDUH). The report provides an overall of the 2012 sample design, describes relative standard errors and design effects, and the use of domain specific design effects for approximating standard error.

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.

This report describes the statistical inference procedures used to produce design-based estimates for the 2011 National Survey on Drug Use and Health (NSDUH). These design-based estimates are presented in the 2011 national findings report detailed tables, as well as the 2011 mental health findings report and detailed tables.

This document focuses on how the prevalence estimates and their standard errors were derived from the 2008 to 2012 MHSS clinical sample. In particular, it describes how the prevalence estimates covering the 2008 to 2012 time period were computed using sampling weights that had undergone a number of calibration adjustments with an emphasis on the last adjustment: poststratification—the annual calibration of the clinical sample to the NSDUH control totals. It then discusses several alternative methods for measuring the standard errors of those estimates.

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.

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).

These are the computer-assisted interviewing (CAI) specifications (English version) to the 2013 National Survey on Drug Use and Health (NSDUH) survey questionnaire.

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.

This report presents an evaluation of the coverage, overlap, biases, strengths, and weaknesses of three sources of data on the receipt of specialty substance use treatment: the National Survey on Drug Use and Health (NSDUH), the National Survey of Substance Abuse Treatment Services (N-SSATS), and the Treatment Episode Data Set (TEDS). Specialty substance use treatment measures compared include numbers and characteristics of persons treated in a given year, single-day treatment counts, numbers of admissions in a given year, and estimates of the numbers of persons who needed substance use treatment but did not receive it. This report includes data from the 2005 through 2010 NSDUHs; 2007 through 2009 N-SSATS; and 2007 through 2009 TEDS. Results are show by substance treated, age, race/ethnicity, and employment status,
