本文的目的是通过比较横断面和纵向分析来研究美国儿童媒体使用的预测因素。数据来自儿童发展补充计划（CDS-I；CDS-II）的第一波和第二波，这是 1997 年 0-12 岁和 2002 年 5-18 岁美国儿童的全国代表性样本。二十四小时时间使用日记用于评估儿童花在媒体（电视、视频游戏、电脑和阅读）上的时间。研究的预测因素包括社会人口统计、社区质量、家庭因素和其他媒体使用。按三个年龄组（学龄前儿童、学龄早期和青春期前）进行普通最小二乘 (OLS) 多元回归。研究结果表明，邻里质量、父母限制和家庭冲突是儿童在一段时间内或一段时间内使用媒体的重要预测因素，但其重要性取决于媒体类型和儿童的发展阶段。此外，儿童的电视观看和阅读习惯是在生命早期形成的，并随着时间的推移而加强。这项研究是第一个从发展角度提供早期情境因素对儿童媒体使用生命历程影响的实证证据的研究。
The purpose of this paper is to examine the predictors of children's media use in the USA, comparing cross-sectional and longitudinal analyses. Data come from Waves 1 and 2 of the Child Development Supplement (CDS-I; CDS-II), a nationally representative sample of American children aged 0-12 in 1997 and 5-18 in 2002. Twenty-four hour time use diaries are used to assess children's time spent with media (television, video games, computers, and reading). Predictors examined include socio-demographics, neighbourhood quality, family factors, and other media use. Ordinary least square (OLS) multiple regressions were performed by three age groups (preschoolers, early school age, and preadolescence). The findings suggest that neighbourhood quality, parental limits and family conflict are significant predictors of children's media use within time or over time, but the significance depends on the type of media and child's developmental stage. In addition, children's television viewing and reading habits are formed early in life and reinforced over time. This study is among the first to provide empirical evidence for the effect of early contextual factors on the life course of children's media use from a developmental perspective.
