Associations between Media Use and Executive Dysfunction among Preschool Children in Bangkok, Thailand

Abstract This study aims to describe the relation between media use characteristics and executive dysfunction in Thai preschoolers. Secondary data were retrieved from a cross-sectional study to compare two Thai executive functions (EFs) assessment forms. Questionnaire data from 110 caregivers of preschool children were analyzed. The research materials included a sociodemographic information form, parenting style and dimensions questionnaire, a 1-week screen time diary, and the behavior rating inventory of executive function-preschool version (BRIEF-P). Findings showed a 23.6% prevalence of executive dysfunction among Thai preschool children. Children's media use characteristics associated with global executive dysfunction included less co-viewing time with caregivers. Shorter co-viewing time was linked to a deficiency of inhibition, emotional control, and planning and organization. Meanwhile, extended viewing of low-quality content was associated with impaired working memory. However, total screen time and setting screen time limits were not associated with executive dysfunction. Co-viewing with caregivers and limiting exposure to low-quality content must be promoted to minimize the adverse effects on EF development.
