This study used a pre-existing national cohort, KnowledgePanel, to recruit adults with resolved AUD. KnowledgePanel has been described in detail elsewhere (https://www.ipsos.com/en-us/solutions/public-affairs/knowledgepanel). Briefly, it is a probability-based sample of non-institutionalized adults that is designed to be representative of the United States and that is maintained by Ipsos Public Affairs for ongoing internet-based research. All KnowledgePanel members are assigned geodemographic weights (i.e., controlling for gender, age, Census region, metropolitan status, education, and income within race/ethnicity group) so that the panel is representative of the U.S. adult population following benchmark distributions from the March 2020 Current Population Survey and the 2018 American Community Survey.
