Abstract
The COVID-19 lockdown has forced young children to spend more time on media and significantly impacted their mothers' mental health. This study explored how mothers' individual distress influences children's problematic media use during the Shanghai citywide lockdown caused by COVID-19. Data were collected from 1889 Chinese mothers (M(age) = 34.69 years, SD = 3.94 years) with preschoolers aged 3-6 years (M(age) = 4.38 years, SD = 1.06 years; 49.0% boys) via an online survey. The statistical analyses relied on SPSS Statistics version 26.0 and macro-program PROCESS 3.3. to investigate the associations and mediation analysis among all the study variables. The results indicated a positive association between maternal distress and children's problematic media use, mediated by parenting stress and maladaptive parenting. Specifically, the serial mediation analysis revealed that high levels of maternal distress exacerbate parenting stress, which in turn leads to maladaptive parenting practices. These maladaptive practices subsequently increase problematic media use in preschool children. The findings highlighted that parents need to enhance their ability to manage risk and promote mental health during periods of significant stress and routine disruption to reduce children's problematic media use.
