The extent to which early childhood exposure to violent media is associated with subsequent adverse child functioning remains disconcerting. In this study, we examine whether preschool child exposure to what parents generally characterize as violent television programming predicts a range of second-grade mental health outcomes.
Participants are from the Quebec Longitudinal Study of Child Development (N = 1786). At 41 and 53 months, parents reported whether the child had viewed television shows and videos consisting of what they judged as violent content.
According to parents, children watched on average 1.8 hours of mixed programming per day. Parent-reported child exposure to televised violence was associated with teacher-reported antisocial symptoms (β = 0.180, 95% confidence interval [CI]: 0.026-0.333), emotional distress (β = 0.224, 95% CI: 0.010-0.438), inattention (β = 0.349, 95% CI: 0.048-0.651), and lower global academic achievement (β = -0.127, 95% CI: -0.237-0.017) in second grade. Violent televiewing was also associated with less child-reported academic self-concept (β = -0.175, 95% CI: -0.296-0.053) and intrinsic motivation (β = -0.162, 95% CI: -0.016-0.307) in second grade. Effects remained significant after adjusting for preexisting child and family characteristics such as baseline child aggression.
This prospective study suggests risks associated with early childhood violent media exposure for long-term mental health in children. These findings, suggesting diffusive relationships between early childhood violent media exposure and negative socioemotional and academic outcomes, empirically support the notion that access to early childhood violent television represents a threat to population health and should be discouraged by adult caregivers.
幼儿时期接触暴力媒体与随后的儿童不良行为之间的关系令人不安。在这项研究中，我们研究了学龄前儿童接触父母普遍认为的暴力电视节目是否会预测一系列二年级心理健康结果。
参与者来自魁北克儿童发展纵向研究（N=1786）。在 41 个月和 53 个月时，父母报告孩子是否观看了他们认为包含暴力内容的电视节目和视频。
根据父母的说法，孩子平均每天观看 1.8 小时的混合节目。父母报告的孩子接触电视暴力与教师报告的反社会症状（β=0.180，95%置信区间[CI]：0.026-0.333）、情绪困扰（β=0.224，95%CI：0.010-0.438）、注意力不集中（β=0.349，95%CI：0.048-0.651）和整体学业成绩下降（β=-0.127，95%CI：-0.237-0.017）有关。暴力电视观看也与孩子报告的较低的学业自我概念（β=-0.175，95%CI：-0.296-0.053）和内在动机（β=-0.162，95%CI：-0.016-0.307）有关。在调整了基线儿童攻击性等现有儿童和家庭特征后，这些影响仍然显著。
这项前瞻性研究表明，幼儿时期接触暴力媒体与儿童长期心理健康风险之间存在关联。这些发现表明，早期接触暴力媒体与负面的社会情感和学业结果之间存在扩散关系，从实证上支持了这样一种观点，即接触早期儿童暴力电视代表了对人口健康的威胁，应该受到成人照顾者的劝阻。
