This report compares the estimated (or realized) precisions of a key set of estimates with the targets for the 2013 National Survey on Drug Use and Health (NSDUH), formerly called the National Household Survey on Drug Abuse (NHSDA). The comparison was made with targets specified by the Substance Abuse and Mental Health Services Administration (SAMHSA) and with the predicted precisions that statisticians from RTI International anticipated during the design of the survey. In addition, tables of realized DEFFs are provided. This report is organized as follows. Chapter 2 summarizes the 2013 sample design. Chapter 3 describes the calculation of relative standard errors (RSEs) and DEFFs. Chapter 4 presents tables that compare the observed precisions with the expected precisions. Chapter 5 compares median and mean DEFFs. Chapter 6 presents median and mean DEFFs for specific analysis domains. Finally, concluding remarks are provided in Chapter 7.

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.

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.
