In addition to watching television, children now have access to and interact with video games, computers, mobile devices, and DVDs that simply did not exist before (common sense media, 2013). Prescriptive research is limited, but current recommendations suggest that children aged three to five should view no more than one hour of screen time per day, and children six to 12 years of age should be limited to two hours of screen time per day (Canadian Paediatric Society, 2017). Although screen time is a pervasive part of a child’s life, reliable estimates on the use of technology, and its impact on various areas of child development are of critical importance. This lends to the research questions of what are the estimated effects of preschool-age screen time on behavioural outcomes and what role do parents play in moderating those effects? The present study examined how screen time is associated with behavioural outcomes in three-year-old children using data from a pregnancy cohort in Calgary, Alberta. The results indicate that 85.3% of the children in this study were exceeding the screen time recommendation of 1 hour per day. Screen time predicted hyperactivity/inattention and separation anxiety, but parental engagement did not moderate those relationships. This research informs on the role of a number of factors that can explain the association between screen time and poor behaviour outcomes. Findings from this study benefit educators and parents by affirming their role as important monitors and limiters of screen time while encouraging other enriching activities for child development.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
