The increasing exposure of adolescents to social media demands their development of critical thinking skills to responsibly deal with online information. Media and Information Literacy for Critical Thinking (MIL-CT) enhances adolescents’ ability to critically assess content, misinformation and digital engagement. In relation to Positive Youth Development (PYD), an MIL-CT intervention has the potential to promote critical thinking skills, reflection, resilience, autonomy, proactiveness, social responsibility, and ethical decision-making in the digital world.
