US parents were surveyed to determine the amount of background television that their children are exposed to as well as to isolate demographic factors associated with increased exposure to background television. After this, we ask how certain home media practices are linked to children's background television exposure.
US parents/caregivers (N = 1454) with 1 child between the ages of 8 months and 8 years participated in this study. A nationally representative telephone survey was conducted. Parents were asked to report on their child's exposure to background television via a 24-hour time diary. Parents were also asked to report relevant home media behaviors related to their child: bedroom television ownership, number of televisions in the home, and how often a television was on in the home.
The average US child was exposed to 232.2 minutes of background television on a typical day. With the use of multiple regression analysis, we found that younger children and African American children were exposed to more background television. Leaving the television on while no one is viewing and children's bedroom television ownership were associated with increased background television exposure.
Although recent research has shown the negative consequences associated with background television, this study provides the first nationally representative estimates of that exposure. The amount of exposure for the average child is startling. This study offers practitioners potential pathways to reduce exposure.
对美国父母进行调查,以确定其子女接触背景电视的时间,并确定与增加背景电视接触相关的人口统计学因素。之后,我们将探讨某些家庭媒体习惯与儿童背景电视接触之间的关系。
这项研究的对象是 1454 名年龄在 8 个月至 8 岁之间的儿童的美国父母/照顾者。通过全国性电话调查进行了此项研究。父母被要求通过 24 小时时间日记报告其子女接触背景电视的情况。父母还被要求报告与子女有关的相关家庭媒体行为:卧室电视拥有情况、家庭中的电视机数量以及家庭中电视机的开启频率。
典型情况下,美国儿童每天接触 232.2 分钟的背景电视。通过多元回归分析,我们发现年龄较小的儿童和非裔美国儿童接触的背景电视更多。无人观看时电视常开以及儿童卧室拥有电视与增加背景电视接触有关。
尽管最近的研究表明背景电视会带来负面影响,但这项研究提供了首次具有全国代表性的背景电视接触估计值。普通儿童的接触量令人震惊。这项研究为从业者提供了减少接触的潜在途径。
