The Role of Different Screen Media Devices, Child Dysregulation, and Parent Screen Media Use in Children's Self-Regulation

Public Policy Relevance Statement This study shows that preschool-aged children's screen time on mobile devices, such as tablets and smartphones, is more negatively related to their self-regulation than their TV use. Children's earlier self-regulatory deficits and parental screen time were mostly unrelated to their media use, and their self-regulation was unrelated to parents' screen time. As young children are increasingly exceeding screen time guidelines, these findings encourage parents and other caregivers to limit children's screen media use in early childhood. Higher TV exposure has been repeatedly linked to poorer self-regulation among young children. Recent studies show that the use of mobile screen media devices is also negatively related to self-regulation in early childhood. Despite the proliferation of mobile devices in households with young children, it is unclear whether children's use of smartphones and tablets predicts their self-regulation independently of TV use and parents' screen media use or when also considering evocative effects of children's dysregulation. This multimethod, cross-sectional study with a racially diverse sample (N = 72) in the western United States examines parents' (86.3% mothers) leisure media use and preschool-aged children's (M = 38.02 months, 55.6% girls, 47.2% racial-ethnic minority) mobile media use, TV use, and dysregulation as predictors of their behavioral battery-assessed self-regulation. As hypothesized, path models show that the amounts of children's mobile media use, TV use, and dysregulation negatively predict their self-regulation, and mobile media use is a stronger predictor than TV use. We conclude with future directions to yield stronger inferences of screen media effects on child development that can inform interventions and screen time guidelines.
