Stay-at-home orders were first issued across the study sites between March 19 and April 6, 2020. Beginning in May 2020, ABCD Study participants were invited to complete surveys measuring the impacts of the pandemic on youth and families. Legal guardians were emailed links for the parent and youth to separately complete three online surveys between May and August 2020, spaced 40 days apart. Links were sent on May 16 (survey 1), June 23 (survey 2), and August 4 (survey 3), with 90% of completions occurring within 2 weeks of sending. Among youth, 5,388, 5,716, and 5,284 completed surveys 1, 2, and 3, respectively. Among parents, 6,860, 7,064, and 6,489 completed surveys 1, 2, and 3, respectively.
