Self-Esteem as a Potential Mediator of the Association Between Social Integration, Mental Well-Being, and Physical Well-Being

Previous research points to a significant impact of social integration and self-esteem on well-being. The present study examined whether self-esteem constitutes one pathway from social integration in the classroom to mental and physical well-being of students and accordingly serves as a mediator. Therefore, 163 students (mean age: 12.98 years, age range: 9–17 years, 57.9% male) of three German secondary schools were examined regarding their experience of social integration, self-esteem, and mental as well as physical well-being. Results revealed that self-esteem mediated the effect of social integration on mental and physical well-being. This finding elucidates one pathway from social integration to well-being and points to the importance of improving both self-esteem and social integration for the promotion of well-being among adolescents.
