RESUMEN
Recent studies have shown the relationship between excessive screen time and autism symptoms. Unfortunately, there are no studies that evaluated the interventions for children with autism symptoms and excessive screen-time. This paper is a preliminary attempt to examine the effects of parent training on the duration of screen-time, repetitive behaviors and brain electrophysiological characteristics in young children with subthreshold autism symptoms and excessive screen time. Results showed that after the 2 months' parent-child interaction, children's screen-time and repetitive behaviors decreased and EEG ratio power in some channels changed. Our findings suggest that parent training have positive effects on young children with excessive screen-time and autism symptoms.
