To investigate associations between adolescent screen time behaviors, screen time rules, and presence of electronic media in the bedrooms of adolescents.
Parents and adolescents (N = 160 dyads) from the cities of Boston, Cincinnati, and San Diego were asked to complete a questionnaire which included questions related to demographics, screen time rules, availability of media devices, and screen time behavior. Separate multiple regression models were used for adolescent and parent reports to test correlates of adolescent television (TV) watching, video game play, and computer usage for entertainment.
Data from adolescents indicated that rules for watching TV, computer usage, and total number of screen time rules were significantly correlated with time spent watching TV (β = -.22, p < .01), playing video or computer games (β = -.18, p < .05), and using the Internet and/or computer for entertainment (β = -.18, p < .05), respectively. Data from parents indicated that TV rules were significantly associated with lower rates of TV viewing, and parent-adolescent agreement on rules strengthened this relationship. Data from parents as well as adolescents indicated that the presence of a TV in the bedroom was positively associated with TV viewing time (β = .18 and .24, p < .05, respectively). Adolescent data indicated a positive association between having at least one video game system in the bedroom and time spent playing video games (β = .19, p < .05).
Having clear rules, setting limits on screen time, and not having screen-based media in the bedroom were associated with fewer hours of screen time for adolescents.
研究青少年屏幕时间行为、屏幕时间规则以及卧室中是否存在电子媒体与青少年之间的关联。
来自波士顿、辛辛那提和圣地亚哥的父母和青少年(N = 160 对)被要求完成一份问卷,其中包括与人口统计学、屏幕时间规则、媒体设备的可用性以及屏幕时间行为相关的问题。使用分别的多元回归模型来检验青少年电视(TV)观看、视频游戏和娱乐性计算机使用的相关因素,模型基于青少年和家长的报告。
青少年的数据表明,观看电视、使用计算机和总屏幕时间规则的规则与观看电视(β = -.22,p <.01)、玩视频或电脑游戏(β = -.18,p <.05)以及使用互联网和/或计算机娱乐(β = -.18,p <.05)的时间显著相关。父母的数据表明,电视规则与观看电视的比率显著降低有关,并且父母与青少年之间对规则的共识加强了这种关系。父母和青少年的数据都表明,卧室中存在电视与观看电视时间呈正相关(β =.18 和.24,p <.05,分别)。青少年数据表明,卧室中至少有一个视频游戏系统与玩视频游戏的时间呈正相关(β =.19,p <.05)。
制定明确的规则、限制屏幕时间以及不在卧室中放置屏幕媒体与青少年的屏幕时间减少有关。
