Social Media Use and Adolescent Mental Health: Mediating and Moderating Roles of Parenting Practices and a Critical Reflection on Existing Research Paradigms from a Family - Education Perspective

In the era of mobile Internet, social media is deeply involved in teenagers' daily life. The same media use behavior will bring different psychological consequences. Family education is regarded as a key influencing factor by many studies. Using the method of literature research, this paper combs the empirical research of journals and dissertations at home and abroad, and analyzes the mediating and regulating effects of different parenting modes, media parenting, and parents' bow behavior on Teenagers' social media use and mental health. This paper not only summarizes the existing research consensus, but also critically reflects on the limitations of the existing research paradigm: most studies tend to the ideal family model, there are causal inference problems, and there is insufficient explanation for the contradictory mixed family that is widespread in reality. The study found that authoritative parenting has psychological buffering effect, but it is not a "panacea"; The effect of media parenting is not simply divided by "restriction/guidance". The negotiation process of rules and the background of parent-child relationship are the key; It is difficult to resolve the internal psychological dilemma simply relying on the control of hard equipment. This study suggests that the psychological risk of teenagers' social media can not be completely attributed to family education, which can provide a reflection reference for family media education and subsequent related research.
