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 report describes the statistical inference procedures used to produce design-based estimates for the 2010 National Survey on Drug Use and Health (NSDUH). These design-based estimates are presented in the 2010 national findings report detailed tables, as well as the 2010 mental health findings report and detailed tables.

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.

The focus of this report is to describe the statistical inference procedures used to produce design-based estimates as presented in the 2020 detailed tables and the 2020 FFR, which are based on restricted-use data.

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.

This is the 2016 NSDUH Statistical Inference Report.
