Screen Time of Preschool-Aged Children and Their Mothers, and Children's Language Development

Although children's increased screen time has been found to associate with poorer language development, it is open to question which part of language ability screen time specifically associates with. Our aim was to examine the association between children's screen time (alone and together with a parent), mothers' screen time, and the different domains of children's language skills. Mothers reported their children's (N = 164, aged 2.5 to 4.1 years) screen time and their own on a weekday and a day off. Children's lexical, phonological, morphological, receptive, and general language abilities were measured using validated tests. The connections between children's and mothers' screen time and children's language skills were analyzed using correlation analyses and linear regression models. The more the children used screen time alone, or the greater the amount of the mothers' screen time, the weaker the children's lexical and general language abilities when the children's age, maternal education level, and birth order were controlled for. We also found cumulative, negative links to the children's lexical and general language abilities when the amount of their screen time alone and the amount of the mothers' screen time were simultaneously included in the regression model. The results suggest that it is important to restrict both children's screen time spent alone and mothers' screen time.
