    • Publications Using SAMHSA DataNSDUH 2018 Person-Level Sampling Weight Calibration Report

    Metadata Updated: September 6, 2025

    This report contains a brief review of the sampling weight calibration methodology used for the 2018 National Survey on Drug Use and Health (NSDUH). This report also lists detailed documentation on the implementation steps and evaluation results from the weight calibration application. The constrained exponential modeling (CEM) method used in the surveys before 1999 (referred to in this report as the generalized exponential model [GEM]) was modified to provide more flexibility in dealing internally with the extreme weights and for setting bounds directly on the weight adjustment factors so they can become suitable for nonresponse (nr) and poststratification (ps) adjustments.
