AbstractThis thesis explores social workers' strategies and perceptions to support youth mental health amid rising social media addiction. It emphasizes a holistic approach that includes digital literacy, mental health screening, well-being and family engagement. Using a qualitative grounded theory approach, data were collected through face-to-face interviews with four social workers, analyzed via the Constant Comparative Method, and interpreted through Social Cognitive Theory (SCT) and Cognitive Behavioral Theory (CBT). The study contributes a youth-centred model to social work theory and practice in Sweden and internationally.Findings reveal that social workers perceive social media addiction as having dual impacts, adverse outcomes like low self-esteem and risky behaviors, and positive potential like peer support and entrepreneurial confidence. Challenges include parental resistance and ethical dilemmas, addressed through trust-building and guiding youths toward positive content. They offered insights into how elements like gender, age, and social environment can deeply affect the experience of addiction and its severity
