Screen time vs. scream time: Developmental interrelations between young children's screen time, negative affect, and effortful control

Abstract

This study aimed to examine developmental relations of screen time, negative affect and effortful control in children aged 12–36 months. Parents of 462 children up to 3 years of age at the start of the study (M = 1.28 years, SD = 0.61; 50% female) participated in four assessments within 10 months. Parents reported their children's screen time, negative affect, and effortful control at each assessment in a diary study. Results of multivariate Bayesian multilevel growth modeling revealed correlations between growth parameters of (1) children's screen time and their negative affect and (2) children's negative affect and their effortful control but not between growth parameters of (3) children's screen time and their effortful control. Overall, these results indicate that children's screen time may be associated with their negative affect independently of their effortful control. Hence, we found no evidence of displacement in the development of self-regulatory strategies in children of parents with higher levels of education. Future research on this topic should focus on children's excessive screen media use, considering contextual and content-related screen media factors and other factors in the child's immediate and broader environment.
