The objective of this research is to enhance comprehension of the strategies employed by field workers to prevent criminal and deviant behaviour among young people in marginalised areas. The data collected from the interviews were examined using thematic analysis and theoretical frameworks such as social capital and social bond theory. The study found that field workers prioritise building strong relationships, trust and creating a sense of purpose for youth. They achieve this by being open and inclusive, showing interest, and socialising with the youth. The activities organised by the field operations were crucial in fostering a sense of purpose in the youth’s daily lives, by catering to their interests and helping them progress.Two key tools that field workers use in their preventive work were identified in this study; field specific competence and a sense for your surroundings.The study also revealed that field workers face challenges such as uncertainty due to lack of clear guidelines, difficulties in managing some youth, and obstacles like limited resources and issues with collaborating with other organisations.
