The use of digital devices by young children is a topic that has gained a lot of attention in recent years. Although scientific advances have been made, the precise influence of these devices on children’s development is still not known. This research examines the association between preschoolers’ use of screens and their social skills, exploring the moderating role of parental mediation in these relationships. 116 parents with at least one child aged 3 to 5 years living in Quebec completed an online questionnaire. No relationship was found between screen time and children’s social skills. In contrast, parental supervision was positively associated with children’s social skills and emerged as a significant moderator of the relationship between screen time and social skills.
