To conduct a meta-analytic review of studies that examine the impact of violent media on aggressive behavior and to determine whether this effect could be explained through methodological problems inherent in this research field.
A detailed literature search identified peer-reviewed articles addressing media violence effects. Effect sizes were calculated for all studies. Effect sizes were adjusted for observed publication bias.
Publication bias was a problem for studies of aggressive behavior, and methodological problems such as the use of poor aggression measures inflated effect size. Once corrected for publication bias, studies of media violence effects provided little support for the hypothesis that media violence is associated with higher aggression. The corrected overall effect size for all studies was r = .08.
Results from the current analysis do not support the conclusion that media violence leads to aggressive behavior. It cannot be concluded at this time that media violence presents a significant public health risk.
对研究暴力媒体对攻击行为影响的研究进行荟萃分析综述，并确定这种影响是否可以通过该研究领域固有的方法学问题来解释。
通过详细的文献检索确定了探讨媒体暴力影响的同行评审文章。计算了所有研究的效应量。针对观察到的发表偏倚对效应量进行了调整。
发表偏倚是攻击行为研究中的一个问题，诸如使用不良攻击测量方法等方法学问题夸大了效应量。一旦校正发表偏倚，媒体暴力影响的研究几乎没有为媒体暴力与更高攻击性相关的假设提供支持。所有研究校正后的总体效应量为r = 0.08。
当前分析结果不支持媒体暴力导致攻击行为的结论。目前不能得出媒体暴力构成重大公共卫生风险的结论。
