A Stronger Association Between Screen Time and Externalizing Problems in Typically Developing Children than in Children with Autism Spectrum Disorder

Excessive screen use is associated with childhood behavioral problems, but whether associations differ between typically developing (TD) children and those with autism spectrum disorder (ASD) is unclear. Our cross-sectional study included 108 children aged 5–9 years (61 TD, 47 ASD). ASD was diagnosed using standardized clinical instruments. Measures included parent-reported screen time (excluding TV/DVD), cognitive ability (K-ABC), and behavioral problems (Vineland-II). Screen time and externalizing problems were associated in the TD group (Spearman’s ρ = 0.361, p < 0.01), but not in the ASD group. In the regression model, screen time (β = 0.40, t = 2.60, p < 0.05), ASD status (β = 0.70, t = 8.30, p < 0.001), and their interaction (β = −0.34, t = −2.06, p < 0.05) significantly predicted externalizing problems. Considering the diversity within the autism spectrum, future studies with larger sample sizes should consider individual heterogeneity when examining the association between behavioral outcomes and screen time.
