The study utilizes a mixed-methods approach, combining both qualitative and quantitative data analysis. Findings suggest that social media use has both positive and negative effects on youth development. On the one hand, social media provides unprecedented opportunities for social networking, self-expression, and information sharing. On the other hand, excessive use of social media can lead to addiction, anxiety, and depression. These findings have important implications for parents, educators, and policymakers in promoting healthy social media use among young people.
