项目摘要

The requested funding for a replacement to relieve the applicant from teaching and administrative duties for a period of 12 months is designed to aid the completion of the project Effects of media violence use in adolescence: A longitudinal study with an experimental intervention that has been funded by the DFG since 2007. The extensive data base of five data waves at yearly intervals provides the possibility of addressing a number of theoretical and methodological questions regarding the development of aggressive behavior in adolescence that go beyond the core research questions specified for the project. To fully exploit this potential and publish the findings in a timely fashion, it is necessary for the applicant to be relieved from regular teaching and administrative duties for the completion of these analyses. The project has generated data for the longitudinal analysis from a sample of 1,750 participants from 96 school classes who were in Grade 7 or 8 at the beginning of the project and took part in at least two of the five measurements. The proposed program of work for the replacement period is directed at three major tasks: (1) The multi-level analysis of the relation between media violence use and aggression over time, seeking to demonstrate interactions between the covariation of media violence use and aggression at the individual level, and patterns of media violence use and aggression at the class level. Such multi-level analyses are currently not available in the international research on media violence and aggression. (2) The analysis of trajectories of aggressive behavior over time in terms of identifying persisting or desisting patterns of aggressive behavior as well as their predictors, using state-of-the-art latent growth curve modeling analyses. Here, the aim is to identify mediating processes that may contribute to the persistence or increase of aggressive behavior patterns in the course of adolescence. (3) The methodological analysis of different operationalizations of media violence use and their divergent or convergent outcomes in relation to aggressive behavior. The present data set provides the opportunity to create indices of media violence use based on different measures of frequency of use and of violent content ratings. Examining the extent to which these different indices show convergent or different relations with aggressive behavior as well as the proposed mediating variables over time can make a significant contribution to the understanding of the role of method variance in interpreting the links between media violence use and aggression in the current research literature.

为免除申请人12个月的教学和行政职责而申请的替代者经费，旨在帮助完成青少年使用媒体暴力的影响项目：一项纵向研究，其中包括一项实验干预，该研究自2007年以来一直由副总干事资助。每年间隔五次的庞大数据库提供了解决有关青春期攻击性行为发展的许多理论和方法问题的可能性，这些问题超出了该项目指定的核心研究问题。为了充分利用这一潜力并及时公布研究结果，申请人有必要免除完成这些分析的常规教学和行政职责。该项目已经为纵向分析生成了数据，样本来自96个学校班级的1750名参与者，他们在项目开始时就读于7年级或8年级，至少参与了五项测量中的两项。更替期间的拟议工作方案针对三项主要任务：(1)多层次分析媒体暴力使用和攻击性随时间推移的关系，力求证明在个人层面上媒体暴力使用和攻击性的协变，以及在阶级层面上媒体暴力使用和攻击的模式之间的相互作用。目前，关于媒体暴力和侵略的国际研究还没有这种多层次的分析。(2)利用最新的潜在成长曲线建模分析，分析攻击行为随时间的轨迹，识别持续或停止的攻击行为模式及其预测因素。在这里，目的是确定可能有助于青春期攻击性行为模式持续或增加的中介过程。(3)媒体暴力使用的不同可操作性及其与攻击行为的差异或趋同结果的方法论分析。目前的数据集提供了根据使用频率和暴力内容评级的不同衡量标准创建媒体暴力使用指数的机会。考察这些不同的指数与攻击性行为的趋同或不同关系的程度，以及所提出的中介变量随时间的变化，有助于理解方法差异在解释当前研究文献中媒体暴力使用与攻击性之间的联系中的作用。
