Adolescent Use of Digital Media and Parental Mediation - A Research Review Digital media are wide spread, frequently used, and highly relevant in the lives of children, adolescents and their parents. Because parents aim to reduce or prevent potential risks of media use for their children, many parents apply different strategies of parental mediation of children's media use: restrictive parental mediation, active parental mediation, co-media use, technical monitoring, and participatory learning. These forms of parental mediation have differential impact on children and adolescents. Different types of media (e. g. television, video games, internet, and mobile phones) have common features but also specific characteristics that lead to partially inconsistent research findings that are not only due to age differences of children and adolescents. Concerning an impact model of parental mediation, the current contribution presents overarching and divergent empirical findings, approaches the effectiveness of parental mediation for cyberbullying, and discusses practical implications as well as research gaps in the analysis of parental mediation.
