Juvenile delinquency among teenage boys in Sweden is a pressing social issue influenced by various factors. This study explores and analyzes these dynamics by examining the perspectives of professional social workers and youth center workers, aiming to understand how peer influences, family dynamics, and community environments contribute to delinquent behavior. Employing a qualitative approach, semi-structured interviews were conducted with social workers and youth center workers. Guided by Social Learning Theory and the Life Model of Social Work Practice, four interviews provided data for content analysis. The findings revealed significant impacts of peer influence, family dynamics, and community environment on juvenile delinquency. Social Learning Theory highlighted the role of observational learning and reinforcement, while the Life Model of Social Work Practice emphasized the interaction between individuals and their environments. This study underscores the need for comprehensive interventions addressing both individual and environmental factors, suggesting future research should incorporate a broader range of variables to enhance understanding and intervention effectiveness.
