Social networks are used daily by almost all adolescents and young people. They are used extensively, and their positive aspects are well-known, but they present multiple risks. Parents’ mediation (PM) in their children’s use of social networks (SNs) to prevent numerous problems has been recently researched. This systematic review analyzed works published since 2012 about online PM strategies concerning the use of SNs by children/adolescents aged between 9 and 18 years old. Following the PRISMA protocol, this review was submitted to Prospero (ID: CRD42022345033), five electronic databases were examined (WOS, SCOPUS, ERIC, ProQuest Psychology, and PubMed), and to assess the risk of bias the ROBIS tool was used. 32 papers were selected. The results indicate that PM strategies (especially the restrictive strategies over the enabling ones) effectively reduce the time spent on SNs and their associated risks. However, it is unclear whether one type of strategy is more effective or whether a combination of the different strategies, depending on the problem to be addressed, is most effective. Finally, no studies have been found that have analyzed the relationship between PM strategies and the benefits associated with the use of SNs. Possible lines of action for future programs and research are proposed.几乎所有青少年与青年群体每日都会使用社交网络（Social Networks, SNs），这类平台的使用频率极高，其积极作用已广为人知，但同时也潜藏诸多风险。近年来，学界针对家长介导（Parental Mediation, PM）子女使用社交网络以规避各类问题的相关研究逐渐增多。本系统综述针对2012年以来发表的、针对9至18岁儿童/青少年使用社交网络时的在线家长介导策略相关研究展开分析。本综述遵循PRISMA报告规范，已在Prospero平台注册（编号：CRD42022345033），共检索了WOS、SCOPUS、ERIC、ProQuest Psychology及PubMed共5个电子数据库，并采用ROBIS工具进行偏倚风险评估。最终共纳入32篇文献。研究结果显示，家长介导策略（相较于赋能型策略，限制性策略的效果更为显著）可有效减少用户在社交网络上的使用时长，并降低相关风险。但目前仍无法明确单一类型的策略是否更具成效，亦或是需根据具体待解决的问题组合使用不同策略，方能达到最优效果。此外，目前尚未有研究探讨家长介导策略与社交网络使用所带来的积极效益之间的关联。本综述最后提出了未来相关研究与实践项目可探索的可行方向。
