NCT ID NCT07731386
First seen Jul 28, 2026 · Last updated Jul 29, 2026 · Updated 1 time
Summary
This study explores whether the amount of daily screen time toddlers are exposed to is related to their language development. Researchers are assessing children aged 12 to 42 months using the Bayley-4, a standard developmental test. The goal is to see if more screen time is linked to differences in receptive and expressive language skills.

Who is studied
Community-based sample of children aged 12 to 42 months who presented consecutively to the pediatric outpatient clinics of a tertiary care city hospital in Türkiye between August 2025 and January 2026, each accompanied by a primary caregiver. Children were enrolled irrespective of the reason for the outpatient visit provided they met the eligibility criteria. The upper age limit of 42 months reflects the normative ceiling of the Bayley-4. Of 153 screened records, 2 were excluded for missing covariate data, yielding an analytical sample of 151.
