Screen Time Linked to Reduced Parent-Child Communication in Early Childhood

In a recent study published in JAMA Pediatrics, researchers from Australia have uncovered a longitudinal link between increased screen time and decreased interactions between parents and their children aged between 12 to 36 months. This correlation underscores concerns around "technoference," the idea that technology may distract from valuable moments of dialogue and interaction within families.

The study, led by Dr. Mary E. Brushe, PhD, and colleagues from various Australian institutions, followed 220 families and closely monitored the home language environment using advanced speech recognition technology, capturing the frequency of adult words, child vocalizations, and conversational turns. The research spanned from January 1, 2018, to December 31, 2021, with statistical analysis concluding in July 2023.

Key findings of the study showed that every additional minute of screen time was associated with fewer instances of adult words spoken, child vocalizations, and conversational exchanges. These effects were noted to be most pronounced at the age of 36 months. For example, an extra minute of screen time at this age correlated with 6.6 fewer adult words, 4.9 fewer child vocalizations, and 1.1 fewer conversational turns.

The results support the concept of technoference and may have significant implications for early childhood language development interventions and support mechanisms. Families may require guidance in understanding the potential associations between screen time and children's language and communication opportunities at home.

The importance of a rich linguistic environment in childhood is well-documented, influencing socioemotional development, IQ, and even brain function. With the rising pervasiveness of screen time in young children's lives, findings from this study present a clear need for mitigating the impacts of screens. Suggestions for potential interventions include fostering interactive co-viewing periods where parents engage with children during screen time, and choosing educational programs engineered to enhance language development.

To advance understanding in this domain, further exploration into the qualities of children's screen time and its diverse impacts on family dynamics is vital. Strategies that incorporate screen time while promoting parent-child interactions could serve as beneficial supports for families in the technologically saturated modern age.

This study was made possible with funding from an NHMRC Ideas Grant and an NHMRC Project Grant. It reflects an extensive collaborative effort to further our comprehension of early childhood development and to potentially direct future educational programs and parenting guidelines towards fostering healthier, more communicative home environments for children.
