“…Later studies have included cross-sectional panel or longitudinal methodology. Some of these key studies involved localized data (e.g., Bade et al, 2021 ; Charles et al, 2021 ; Evans et al, 2021 ; Fruehwirth et al, 2021 ; Graupensperger et al, 2021 ; Jackson et al, 2021 ; Lechner et al, 2021 ; Minhas et al, 2021 ; Ryerson et al, 2021 ; Salazar-Fernández et al, 2021 ; Ward et al, 2021 ), while others utilized national data. Of those using national data, some have included trend data ( Schulenberg et al, 2021 ) but have not specifically examined changes during the pandemic while controlling for existing trends; others have included limited data points (i.e., one or two) preceding the COVID-19 pandemic (e.g., Barbosa et al, 2021 ; Daly and Robinson, 2021 ; Oksanen et al, 2021 ; Pollard et al, 2020 ), while others included only data points after pandemic onset (e.g., Irizar et al, 2021 ; Nordeck et al, 2021 ).…”
