This study explores the impact of social integration on the sociocultural adaptation of university students, with a particular focus on the mediating role of campus recreation services. Recognizing the challenges faced by international students in adapting to new cultural environments, the research highlights the significance of recreation services as a supportive mechanism. Data were collected from international students at a large Turkish university, utilizing validated instruments to assess recreation service quality, social integration, and sociocultural adaptation. Structural equation modeling (SEM) was employed to analyze the data, revealing that recreation services exert both direct and indirect effects on sociocultural adaptation through social integration. The findings demonstrate that high-quality recreation services not only facilitate social bonding among students but also contribute to their cultural adjustment by creating inclusive and engaging environments. These results emphasize the importance of campus recreation as a strategic tool in higher education, fostering a sense of belonging and enhancing cross-cultural experiences. This study offers valuable insights for university administrators, recreation program developers, and policymakers seeking to improve the campus experience for diverse student populations. By prioritizing the role of recreation in promoting social integration and cultural adaptation, institutions can better support the well-being and success of their international students.
