Impact of the Use of Interactive Screens on Language Development in Children up to 6 Years of Age: A Systematic Review.
Djalma Carmo da Silva Junior, Yasmin Marques Castro, Rinelly Pazinato Dutra and 2 others
PMID 41235618WHAT IT FOUND
Interactive screens do not uniformly harm language.
Heavy, solitary use is linked to delays and poorer vocabulary, but supervised co-viewing or educational content can support learning. Clinicians should assess how and with whom the child uses the device, not just total screen time.
Key findings
01Several studies found negative associations between heavy screen use and language outcomes, including speech delays and lower vocabulary scores.
02Other studies found no significant association between screen use and language development, suggesting the relationship is not universal.
03Some evidence suggests that interactive content or shared use may have positive effects on language skills, contrasting with passive or isolated use.

What it does not show
Most included studies were cross-sectional, so they cannot prove that screens cause language delays. Screen time was largely measured by parent report, which is prone to recall bias. The review included heterogeneous methods for defining and measuring 'interactive screen use' and language outcomes. Many studies did not control for key confounders like socioeconomic status or parental interaction quality.
Declared interests
The authors declare no conflicts of interest. The study was funded by the Coordination for the Improvement of Higher Education Personnel.
The easy way to misread this
Do not conclude that all screen use is harmful or that all screen use is safe. The evidence is inconsistent and mostly observational. Do not advise strict screen bans based on this review alone, as it does not prove causation and suggests that context and interaction quality matter more than total time.
