ABSTRACT The widespread use of smartphones and tablets has greatly increased screen exposure among preschoolers. Since early childhood is crucial for cognitive, behavioural and social development, excessive screen time represents a major public health concern. Identifying factors influencing young children's screen use is vital for creating effective family guidance and health policies. Using convenience sampling, this study collected data from 633 parents across 31 countries to examine how family composition, parental and child characteristics affect the screen time of preschoolers (aged 1–5 years). The model, based on Ordinary Least Squares regression, explained 42% of the variance in children's screen time. Parental device‐giving frequency emerged as the strongest predictor, with more frequent giving linked to greater exposure. Screen time also increased with child age and the number of children in the family. Children supervised by mothers had significantly less screen time than those supervised by fathers. Parental age, number of adults in the home, child's sex and temperament were not significant predictors. These findings highlight the significant impact of parental behaviour and household dynamics on preschoolers' screen habits. Interventions should directly target these factors, and family screen time guidelines must evolve to reflect the modern technology landscape, promoting balanced and healthy use.
