Note: Adaptation to virtual format occurred in March 2020. Items highlighted in blue indicate COVID-19 related reasons for withdrawal. % referred = eligible patients (screened, not excluded) referred for trial; % enrolled = patients referred and enrolled; % withdrawn = youth withdrawn out of total enrolled. Two enrolled youth for in-person treatment immediately withdrew during the initial transition to the virtual format, as both did not want virtual treatment. Four in-person enrolled youth decided to continue with virtual treatment during the initial transition (these youth were considered “hybrid” because they received both in-person and virtual components). The “dual” phase occurred March-July 2021; both in-person and virtual options were available and individual youth remained in the chosen format. One youth, however, in the dual phase received a combination of formats in order to work with the family’s availability.
