This National Survey on Drug Use and Health (NSDUH) methodological report examines the feasibiilty and impacts of a variety of sample design changes on survey costs and data precision.

This report describes the sample design to the 2011 National Survey on Drug Use and Health (NSDUH).

If the Substance Abuse and Mental Health Services Administration (SAMHSA) is to move NSDUH to a hybrid ABS/field-enumerated frame, several questions will need to be answered, procedures will need to be developed and tested, and costs and benefits will need to be weighed. This report outlines what is known to date, how it may be applied to NSDUH, and what additional considerations need to be addressed.

This report evaluates NSDUH\'s coverage of several demographic, socioeconomic, and geographic domains or subpopulations that are of interest to data users. It is intended to be an informative summary of NSDUH coverage with respect to other sources of data. In most cases, the data source that is used for comparison is a primary source of information on that domain or another flagship survey of HHS.

This report describes the sample design to the 2012 National Survey on Drug Use and Health (NSDUH). A coordinated sample design was developed for the 2005 through 2009 NSDUHs. The 2010-2011 and 2012-2013 samples are extensions of the 5-year sample. This report describes the general sample allocation procedures for the main NSDUH study, the NSDUH\'s Mental Health Surveillance Study, and the Questionnaire Field Test.

This report describes the general principles and procedures for editing and imputation for the variables in the 2012 National Survey on Drug Use and Health (NSDUH). The report also describes imputation and the predictive mean neighborhood methodology.

This report describes changes in the 2014 and 2015 NSDUHs that were designed to increase the efficiency of data collection and processing and to improve the quality of the data collected. In 2014, changes were made in the sample sizes allocated to each state and to different age groups in order to increase the precision of national and many state estimates as well as estimates for older adults. In 2015, changes were made to the survey questionnaire to improve the quality of the data collected, expand the number of prescription drugs covered, and address changing substance use and mental health policy and research needs. New data collection equipment was introduced in 2015 to replace the older equipment in the field. Respondent materials also were updated. This report provides information on the key changes made as well as some of the potential implications for data users.

This report describes the sampling design for the 2015 NSDUH.

Although PMN imputation as currently implemented has a number of advantages, including the ability to use a large number of similar variables to determine the imputed value and to provide individual record consistency among very complex variable relationships, the goal of this study was to evaluate this method compared with other options, especially in the context of the redesign of the NSDUH.

This report compares specific health conditions, overall health, and health care utilization prevalence estimates from the 2006 National Survey on Drug Use and Health (NSDUH) and other national data sources. Methodological differences among these data sources that may contribute to differences in estimates are described. In addition to NSDUH, three of the data sources use respondent self-reports to measure health characteristics and service utilization: the National Health Interview Survey (NHIS), the Behavioral Risk Factor Surveillance System (BRFSS), and the Medical Expenditure Panel Survey (MEPS). One survey, the National Health and Nutrition Examination Survey (NHANES), conducts initial interviews in respondents\' homes, collecting further data at nearby locations. Five data sources provide health care utilization data extracted from hospital records; these sources include the National Hospital Discharge Survey (NHDS), the Nationwide Inpatient Sample (NIS), the Nationwide Emergency Department Sample (NEDS), the National Health and Ambulatory Medical Care Survey (NHAMCS), and the Drug Abuse Warning Network (DAWN). Several methodological differences that could cause differences in estimates are discussed, including type and mode of data collection; weighting and representativeness of the sample; question placement, wording, and format; and use of proxy reporting for adolescents.
