be incompatible with the study’s focus on understanding successful recovery, potential participants with AUDIT-C scores above recognized thresholds (i.e., ≥4 for men; ≥3 for women) were excluded as they would constitute a contrasting population that had not achieved recovery. In total, 31,386 KnowledgePanel members were invited to participate, of whom 17,622 completed an eligibility screening (56% response rate). Of those respondents, 3285 self-identified as being in recovery or having resolved a past alcohol problem; however, 1648 (50%) of those same respondents had AUDIT-C scores indicative of current hazardous drinking and were excluded. Of the remaining participants, 1637 met eligibility criteria and completed the survey questionnaire. During data preparation, we discovered erroneous or inconsistent responses from 145 respondents and subsequently excluded them because of low data quality. The final analytic sample consisted of 1492 adults with resolved AUD. As compensation, participants received 20,000 KnowledgePanel points, worth approximately $20, which they could redeem for prizes from Ipsos. Study materials and procedures were reviewed and approved by the University of Iowa Institutional Review Board.
