The increased prevalence of media multitasking among adolescents has raised concerns that media multitasking may cause attention problems. Despite cross-sectional evidence of the relationship between media multitasking and attention problems, no study has yet investigated this relationship longitudinally. It is therefore unclear how these two variables are related. Two 3-wave longitudinal studies with 3- and 6-month time lags were conducted. In total, 2,390 adolescents aged 11–16 provided data on media multitasking and attention problems. Findings from random intercept autoregressive cross-lagged models suggest that media multitasking and attention problems were strongly related between individuals. Empirical evidence for a potential detrimental long-term effect of media multitasking on attention problems was only found among early adolescents but not among middle adolescents.

青少年媒体多任务与注意力问题的关系：两项纵向研究的结果

青少年中媒体多任务处理的日益流行引起了人们的关注，即媒体多任务处理可能会引起注意力问题。尽管有横截面证据表明媒体多任务处理和注意力问题之间存在关系，但尚无纵向研究。因此，尚不清楚这两个变量如何相关。进行了两个3个月和6个月时滞的3波纵向研究。总共有2390名11-16岁的青少年提供了有关媒体多任务处理和注意力问题的数据。随机截距自回归交叉滞后模型的发现表明，媒体多任务处理和注意力问题与个人之间密切相关。
