NSDUH 2020 Person-Level Sampling Weight Calibration Report

Learn about the techniques used to create weights for the 2020 National Survey on Drug Use and Health (NSDUH) at the person level. The report reviews the generalized exponential model (GEM) used in weighting, discusses potential predictor variables, and details the practical steps used to implement GEM. The report also details the weight calibrations, and presents the evaluation measures of the calibrations, as well as a sensitivity analysis.Chapters:Introduces the survey design, weight components, and the remainder of the report.Discusses the impact of the survey interruption on the weighting for 2020.Reviews GEM and outlines how GEM provides a unified approach to adjustments for nonresponse, poststratification, and extreme weights.Discusses potential predictor variables and the strategy for dealing with many predictors.Discusses extreme weights in the GEM.Discusses the control totals for poststratification adjustments.Details the weight calibrations at the dwelling unit level.Discusses the design weight components and weight calibration at the person level.Presents the evaluation measures of calibrated weights and a sensitivity analysis of selected prevalence estimates.Discusses the break-off analysis weights.Appendices include technical details about the model and the evaluations that were performed.
