In May 2020, shortly after the pandemic began and the data collection for the latest lifespan protocol had just begun, we added adapted versions of the CoRonavIruS Health Impact Survey (CRISIS) PhenX questionnaire [40] and the ABCD (Adolescent Brain Cognitive Development Study) COVID questionnaire [41] to the COGA assessment protocol to capture major COVID-19 related stressors, healthy coping activities, and changes in alcohol use/misuse since the onset of the pandemic in March 2020. While data collection is ongoing, as of July 22, 2022, questionnaire data had been obtained on 1654 participants. Genome-wide association data are available in 96.1% of this sample, and EEG assessments are available in 75.7% of the sample. Of those who completed the COVID-19 questionnaire, 61.8% were female, 79% were White, and the average age was 50.7 (Table 1).Table 1Descriptive characteristics of COGA’s lifespan project COVID-19 sample, stratified by pre-pandemic AUD status.All participants (N = 1651)No past AUD (N: 645)Current AUD symptoms (N: 606)Remitted AUD, Drinking (N: 231)Remitted AUD, Not-Drinking (N: 169)Socio-demographics Female (%)61.874.9a51.760.250.3 Self-reported Black (%)16.121.2a15.88.27.7 Self-reported White (%)79.074.777.688.388.8 Self-reported Hispanic (%)7.96.010.17.86.5 Age (Mean, SD)50.7 (15.8)49.7
