Differential roles of problematic media use by mothers and toddlers in the relation between parenting stress and toddlers' socioemotional development.

The increasing prevalence of digital media devices in families with young children has raised concerns over problematic media use. However, the link between toddlers' problematic media use, their socioemotional development, and the influence of parental factors remains unclear. The current study examined the roles of problematic media use by both mothers and toddlers in the association between maternal parenting stress and toddlers' socioemotional development. Participants comprised 215 mothers and 73 lead child care classroom teachers of toddlers aged 24-36 months enrolled in child care centers in South Korea. Mothers reported parenting stress and problematic media use by themselves and their toddlers, and child care teachers reported toddlers' socioemotional development. The results from structural equation modeling analysis revealed that maternal parenting stress was related to toddlers' socioemotional development both directly and indirectly through toddlers' problematic media use, both alone and in conjunction with mothers' problematic media use. Although maternal parenting stress was related to mothers' problematic media use, mothers' problematic media use was not directly related to toddlers' socioemotional development. These findings underscore the importance of toddlers' problematic media use in their socioemotional development and highlight the need for comprehensive approaches that address family dynamics, such as maternal parenting stress and problematic media use.
