- 요약Attention-deficit/hyperactivity disorder (ADHD) is associated with increased risk for internalizing and externalizing psychiatric disorders, functional impairment, and risky behaviors across the lifespan. Psychostimulants, the first-line treatment for ADHD, reduce symptoms of hyperactivity and impulsivity, but show limited efficacy for reversing common sequalae of this disorder (e.g., more serious externalizing conditions), once established. Thus, targeting environmental factors through which these conditions are shaped and maintained may be required.Decades of research has assessed relations between ADHD symptoms and screen time (i.e., time watching television, playing video games, and using other screen-based devices). However, much of this research is cross-sectional and relies on decades-old data that does not reflect the current media environment. In addition, many studies evaluate effects of media use on ADHD symptoms, but not the reverse relation, despite evidence suggesting that certain characteristics may predispose individuals to use screen media more. Finally, few studies assess potential moderators of these relations, which is critical to identify subgroups of individuals who are especially susceptible to media effects.This study examined relations between ADHD symptoms and screen time in the Adolescent Brain Cognitive Development (ABCD) study, an ongoing longitudinal study that includes a large, nationally representative sample of young children in the United States, with nearly 12,000 participants at baseline. I assessed bidirectional relations between self-reported screen time and ADHD symptoms over one year (baseline and one-year follow-up). In addition, I assessed candidate moderators of these relations: ADHD presentation, sex, socioeconomic status (SES), and race/ethnicity. Finally, based on evidence that both screen time and ADHD symptoms are associated with altered reward processing, I assessed relations between screen time and neural responding during anticipation of reward over two years (baseline and two-year follow-up).I found that ADHD symptoms and screen time were reciprocally related, such that each predicted the other over a one-year time period. Effects of baseline screen time on later ADHD symptoms were stronger for children with fewer symptoms of sluggish cognitive tempo (a set of symptoms associated with social withdrawal and academic impairment, over-and-above ADHD presentation) and for white, non-Hispanic children. In addition, baseline screen time predicted blunted responding during reward anticipation in subcortical brain regions two years later. The reverse relation (i.e., a negative association between neural responding during reward anticipation and subsequent screen time) was also observed for subcortical brain regions and subregions of orbitofrontal cortex. These results suggest that screen time may represent a potential target for intervention among individuals with ADHD symptoms. Furthermore, they indicate that individuals with increased ADHD symptoms are more likely to use screen media, which may exacerbate current symptoms or predispose them to other media effects on socioemotional development or psychiatric health. These bidirectional effects may be particularly salient for certain subgroups of children (e.g., children with less sluggish cognitive tempo; white, non-Hispanic children). Finally, to my knowledge, this is the first study to demonstrate bidirectional effects between media use and neural responding during reward anticipation, which points to a potential pathway by which screen media increases risk for ADHD and other internalizing/externalizing disorders and/or by which ADHD symptoms increase the likelihood of excessive media use.
