The impact of children's use of "screen" media including television and computer games, continues to be debated. The American Academy of Pediatrics (AAP) until recently recommended a relatively restrictive screen time diet of 2 h or less for most youth. A representative correlational sample of youth were assessed for links between screen time and risky behavioral outcomes. Data collection occurred in 2013 conducted by the State of Florida. Use of screens that was moderately high, in excess of the AAP's former recommendations, but not excessive (1 SD or higher than average), was not associated with delinquency, risky behaviors, sexual behaviors, substance abuse, reduced grades or mental health problems. Even excessive screen use (1 SD or higher) was only weakly associated with negative outcomes related to delinquency, grades and depression only, and at levels unlikely to be practically significant. Results conceptually replicate those of Przybylski (2014) with a US sample for depression and delinquency as outcomes. Moderate use of screens, though in excess of the AAP's historical recommendations, are unassociated with problem outcomes. Excessive use of screens is only weakly associated with negative outcomes, and only those related to depression and delinquency as well as reduced grades, but not risky driving, substance use, risky sex or disordered eating. Although an "everything in moderation" message when discussing screen time with parents may be most productive, results do not support a strong focus on screen time as a preventative measure for youth problem behaviors.
儿童使用“屏幕”媒体(包括电视和电脑游戏)的影响仍在争论中。直到最近,美国儿科学会 (AAP) 还建议大多数年轻人的屏幕时间限制在 2 小时或更短。代表性的相关样本青少年被评估屏幕时间与危险行为结果之间的联系。数据收集于 2013 年在佛罗里达州进行。屏幕使用时间适度较高,超过 AAP 之前的建议,但不过度(高于平均水平 1 个标准差或更高),与犯罪行为、危险行为、性行为、药物滥用、成绩下降或心理健康问题无关。即使是过度的屏幕使用(高于平均水平 1 个标准差)也仅与犯罪行为、成绩和抑郁相关的负面结果弱相关,且不太可能具有实际意义。结果在概念上复制了 Przybylski(2014 年)的研究结果,以美国样本为抑郁和犯罪行为的结果。尽管屏幕使用量适度较高,超过了 AAP 的历史建议,但与问题结果无关。过度使用屏幕仅与负面结果弱相关,并且仅与抑郁和犯罪行为以及成绩下降相关,而与危险驾驶、药物使用、危险性行为或饮食失调无关。尽管在与父母讨论屏幕时间时,“适度一切”的信息可能最有效,但结果并不支持将屏幕时间作为预防青少年问题行为的主要措施。
