Screen time in 36-month-olds at increased likelihood for ASD and ADHD

Area of Science:

• Developmental Psychology
• Pediatric Neurodevelopment
• Child Language Acquisition

Background:

• Understanding the impact of screen time on early child development is crucial.
• Children with a family history of Autism Spectrum Disorder (ASD) or Attention-Deficit/Hyperactivity Disorder (ADHD) may be at higher risk for developmental differences.
• The interplay between media consumption, behavior, and language in toddlers requires further investigation.

Purpose of the Study:

• To investigate the association between video-based media viewing (screen time) and developmental outcomes in 36-month-old children.
• To compare screen time and language development across children with Autism Spectrum Disorder (ASD), elevated Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms, and typically developing peers.

Main Methods:

• A cohort of 120 children aged 36 months was assessed.
• Participants were categorized into diagnostic groups: ASD, ADHD Concerns, and Comparison.
• Screen time was measured, and language development (receptive and expressive) was evaluated.

Main Results:

• Children with ADHD Concerns exhibited significantly higher screen time compared to the Comparison group.
• Across all groups, increased screen time was correlated with diminished receptive and expressive language abilities.
• No specific diagnostic group differences in screen time were found beyond the ADHD Concerns group.

Conclusions:

• Higher screen time in toddlers is associated with poorer language development, irrespective of family history of ASD or ADHD.
• The findings highlight a potential concern for early language acquisition in relation to media exposure.
• Longitudinal research is necessary to establish causality and the direction of the relationship between screen time and developmental outcomes.
