RT Journal Article SR Electronic T1 Societal Disruptions and Childhood ADHD Diagnosis during the COVID-19 Pandemic JF Journal of Human Resources FD University of Wisconsin Press SP S187 OP S226 DO 10.3368/jhr.1222-12708R2 VO 59 IS S A1 Freedman, Seth A1 Marquardt, Kelli A1 Salcedo, Dario A1 Simon, Kosali A1 Wing, Coady YR 2024 UL http://jhr.uwpress.org/content/59/S/S187.abstract AB We study how the societal disruptions of the COVID-19 pandemic impacted diagnosis of a prevalent childhood mental health condition, attention deficit hyperactivity disorder (ADHD). Using both nationwide private health insurance claims and a single state’s comprehensive electronic health records, we compare children exposed to the pandemic to same-aged children prior to the pandemic. We find the pandemic reduced new ADHD diagnoses by 8.6 percent among boys and 11.0 percent among girls nationwide through February 2021. We further show that higher levels of in-person schooling in fall 2020 dampened the decline for girls but had no moderating effect for boys.
