Cross-Sectional Retrospective Assessments versus Longitudinal Prospective Assessments of Substance Use Change among Young Adults during COVID-19: Magnitude and Correlates of Discordant Findings.

ABSTRACT: Significance: Findings regarding changes in substance use since COVID-19 have been mixed, potentially due to differences in methods used to assess change. Thus, we compared changes in substance use per retrospective self-report at one time-point (March-May 2020) versus prospective, longitudinal self-report across 2 time-points (Sept-Dec 2019; March-May 2020), and identified predictors of discordance. Methods: We analyzed data from a longitudinal study of 1,082 young adults from 6 metropolitan areas. Across cigarettes, e-cigarettes, marijuana, and alcohol, participants were categorized as Increasers (increased based on both methods), Decreasers/Stable (decreased/same per both methods), Over-reporters (decreased/same per longitudinal data/increased via retrospective report), or
