ABSTRACT Little is known about how parents utilized parental mediation strategies during the early months of the COVID-19 pandemic, which saw an upsurge in youths’ technology use and increased family time at home. The current study surveyed the parents of 964 U.S. school-aged children for their mediation behaviors, perceptions of media risk, views about youth media use, and awareness of and reliance upon professional youth media guidelines to identify key factors influencing the use of media parenting strategies (i.e. parental mediation) during the lockdown (March – May 2020). Structural equation modeling revealed that parents’ use of professional media use guidelines and their perceived changes in media views during the lockdown were positively related to their use of active mediation, restrictive mediation, and coviewing. Further, perceptions of media risk were associated with restrictive mediation, but not other mediation types, and single parents were less likely to engage in active and restrictive mediation than parents with a partner.
