This study assessed the claim that children's television use interferes with time spent in more developmentally appropriate activities.
Data came from the first wave of the Child Development Supplement, a nationally representative sample of children aged 0 to 12 in 1997 (N = 1712). Twenty-four-hour time-use diaries from 1 randomly chosen weekday and 1 randomly chosen weekend day were used to assess children's time spent watching television, time spent with parents, time spent with siblings, time spent reading (or being read to), time spent doing homework, time spent in creative play, and time spent in active play. Ordinary least squares multiple regression was used to assess the relationship between children's television use and time spent pursuing other activities.
Results indicated that time spent watching television both with and without parents or siblings was negatively related to time spent with parents or siblings, respectively, in other activities. Television viewing also was negatively related to time spent doing homework for 7- to 12-year-olds and negatively related to creative play, especially among very young children (younger than 5 years). There was no relationship between time spent watching television and time spent reading (or being read to) or to time spent in active play.
The results of this study are among the first to provide empirical support for the assumptions made by the American Academy of Pediatrics in their screen time recommendations. Time spent viewing television both with and without parents and siblings present was strongly negatively related to time spent interacting with parents or siblings. Television viewing was associated with decreased homework time and decreased time in creative play. Conversely, there was no support for the widespread belief that television interferes with time spent reading or in active play.
本研究评估了儿童观看电视会干扰其参与更具发展适宜性活动的时间这一说法。
数据来自《儿童发展补充调查》的第一波,该调查于1997年对全国具有代表性的0至12岁儿童样本进行(N = 1712)。使用从1个随机选择的工作日和1个随机选择的周末日记录的24小时时间使用日记,来评估儿童看电视的时间、与父母相处的时间、与兄弟姐妹相处的时间、阅读(或被阅读)的时间、做作业的时间、进行创造性游戏的时间以及进行积极游戏的时间。采用普通最小二乘多元回归来评估儿童观看电视的时间与参与其他活动时间之间的关系。
结果表明,无论是否有父母或兄弟姐妹陪伴,看电视的时间分别与与父母或兄弟姐妹在其他活动中的相处时间呈负相关。看电视也与7至12岁儿童做作业的时间呈负相关,并且与创造性游戏呈负相关,尤其是在非常年幼的儿童(5岁以下)中。看电视的时间与阅读(或被阅读)的时间或积极游戏的时间之间没有关系。
本研究结果首次为美国儿科学会在其屏幕时间建议中所做的假设提供了实证支持。无论有无父母和兄弟姐妹在场,看电视的时间与与父母或兄弟姐妹互动的时间都呈强烈负相关。看电视与作业时间减少和创造性游戏时间减少有关。相反,对于电视会干扰阅读时间或积极游戏时间这一普遍观点,本研究并未提供支持。
