The problem
Intervention: Various media parenting practices including parental monitoring, setting limits on screen time, modelling healthy screen use, managing screens at mealtimes and in bedrooms, and use of screens for behaviour management
Who it was tested with: 7,947 early adolescents with mean age 12.9 years from the Adolescent Brain Cognitive Development Study; subsample of 840 with smartphone app-reported data.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"We used data from the Adolescent Brain Cognitive Development Study, a prospective cohort of 7947 adolescents [Mage 12.9 years]. Media parenting practices from Year 3 (2019-2021) and adolescent-reported screen time, app-reported smartphone time (subsample N = 840), and problematic screen use from Year 4 were analyzed using linear regression models adjusted for potential confounders." This prospective cohort design with adjustment for confounders provides evidence of associations between specific parenting practices and child screen outcomes, though the direction of causality cannot be definitively determined.
Prospective design does not establish causation; bidirectional relationships possible between parental practices and child outcomes; self-reported screen time may be subject to recall bias
