Mental Health Effects of Internet Violence on Children

这项申请是对疾病控制和预防中心关于研究接触媒体暴力和青少年暴力之间的联系的合作协议的回应。我们提议在全国范围内对10-15岁的年轻人进行电话调查。当局会透过电话与青少年及其父母联络，然后透过互联网与他们会面，并安排两次跟进访问。虽然已经对电视暴力进行了大量研究，但对新媒体，特别是互联网的关注要少得多。互联网曝光对年轻人攻击性和暴力行为的影响可能比其他媒体曝光更大，因为 增强了涉及的互动性、逼真的图形和其他视觉刺激。由于这是一项年轻人可以大量接触的新兴技术，拟议的研究对公共卫生政策和实践具有重要影响。 我们建议对1400个家庭进行研究，其中包括一名照顾者和一名10-15岁的互联网用户儿童。数据将在两年内的三个时间点收集。参与者将通过随机数字拨号被识别出来，然后被引导到一个互联网网站对调查做出回应。这种方法结合了电话和基于网络的调查的优势，产生的结果最大限度地具有代表性，同时最大限度地减少了回答偏差。接触暴力新媒体和攻击行为之间的关系将在基线访谈后的两年内进行监测。我们假设孩子们和 与其他儿童和青少年相比，使用暴力媒体(包括暴力网站和视频/电脑游戏)的青少年随着时间的推移会表现出更多的暴力和攻击性行为。此外，我们认为，个体因素，如性别和特质攻击，以及情境因素，如目睹暴力，将是理解暴力媒体和暴力行为之间联系的重要组成部分。

This application is in response to the RFA from the Centers for Disease Control and Prevention for a cooperative agreement for research on the association between exposure to media violence and youth violence. We are proposing to conduct a national telephone survey of youth ages 10-15. Youth and their parents will be contacted by telephone and then interviewed through the Internet with two follow-up interviews scheduled. Although much research has been conducted with respect to television violence, much less attention has been paid to new medias, especially the Internet. It is likely that Internet exposures have a greater effect on aggressive and violent behavior of young people than other media exposure because of the heightened interactivity involved, realistic graphics, and other visual stimulation. Because this is an emerging technology to which youth have significant access, the proposed study has important implications for public health policy and practice. We propose a study of 1,400 households, including one caregiver and one child ages 10-15 who is a user of the lnternet. Data will be collected at three time points over a two-year time period. Participants will be identified via random digit dialing and then directed to an Internet site to respond to the survey. This method marries the strengths of telephone and web-based surveys to produce results that maximize representativeness while minimizing response bias. The relationship between exposure to violent new media and aggressive behavior will be monitored for two years atter the baseline interview. We hypothesize that children and acolescents who utilize violent media, including violent web sites and video/computer games, will manifest more violent and aggressive behaviors over time compared to other children and adolescents. In addition, we hxpothesize that individual factors such as sex and trait-aggression, and contextual factors such as witnessing violence will be important components inunderstanding the association between violent media and violent behavior.
