The current course of research aims to understand the connection between community engagement and the well-being of university students. It aims to demonstrate the effect of the frequency of use of social networks, the accessibility of content, diversity, and the level of participation within the community on the improvement of the emotional state of students, their sense of belonging, and the reduction of stress. These findings suggest a multidimensional link: although some aspects of community engagement have positive implications for well-being, others are either positive or harmful. Regular community participation enhances psychological well-being and sense of belonging, but not emotional well-being or stress reduction. Access to community services positively impacts emotional health but not community connectedness. The study found a negative relationship between community diversity and well-being outcomes, highlighting the impact of tensions in heterogeneous contexts. High engagement levels are crucial for community engagement but can lead to negative emotions and decreased community identification. The findings highlight the complexity of community engagement and student well-being.
