Screen time is a predictor of cognitive function in children with attention deficit hyperactivity disorder

Area of Science:

• Neuroscience
• Developmental Psychology
• Child Psychiatry

Background:

• Screen exposure is a growing concern for cognitive development in children with Attention Deficit Hyperactivity Disorder (ADHD).
• Understanding factors influencing cognitive function in ADHD is crucial for effective interventions.

Purpose of the Study:

• To investigate the relationship between daily screen time and cognitive function in children diagnosed with ADHD.
• To identify other significant risk factors impacting cognitive performance in this population.

Main Methods:

• The study involved 184 children (aged 6-16) diagnosed with ADHD.
• Cognitive function was assessed using the Das-Naglieri cognitive assessment system (DN:CAS) Chinese version.
• Multiple linear regression analysis examined predictors of DN:CAS subscale scores, including IQ, screen time, and socioeconomic factors.

Main Results:

• Higher intelligence quotient (IQ) was significantly associated with better cognitive function scores.
• Reduced daily screen time emerged as a strong predictor of enhanced cognitive performance.
• Higher maternal education level also correlated positively with improved cognitive function.

Conclusions:

• Intelligence quotient, controlled screen time, and maternal education are key predictors of cognitive function in children with ADHD.
• Parents play a vital role in managing children's screen time to support cognitive development.
• The DN:CAS Chinese version, based on PASS theory, offers a valuable tool for assessing cognitive function in ADHD.
