Has Screen Use Crossed the Line? (with Brad Marshall) [R]

In this episode of Dr. Justin Coulson's Happy Families podcast, host Justin Coulson is joined by Dr. Brad Marshall, Chief Research Officer at Control Shift and researcher at Macquarie University, to discuss the growing crisis of internet gaming disorder and smartphone overuse among Australian primary and secondary school children. Drawing on their 2023 study of over 1,000 students across independent schools, they reveal alarming statistics: high school students spend an average of nine hours per day on recreational screens, while primary schoolers average just over six hours—far exceeding the two hours reported by the e-safety commissioner. The study also found that nearly 10% of Australian children exhibit medium to high levels of smartphone addiction, with about 5% showing signs of clinical or subclinical gaming disorder. Crucially, the research shows that these behaviors have significant developmental impacts across education, emotional health, social development, and physical well-being—especially when they cross into compulsive use. The conversation shifts from alarming data to practical parenting strategies, with Brad Marshall warning against three critical mistakes: criticizing children’s online behavior in the moment (which triggers defensiveness), allowing screen access in bedrooms (which disrupts sleep and snowballs into broader issues), and having emotional screen-related conversations while the child is still on a device. Instead, he advocates for calm, intentional conversations during relaxed times and thoughtful transitions off screens. The episode ends with a call for better parental controls and policy support to empower parents in setting healthy boundaries.
