The purpose of this study was to assess the effect of loneliness on academic participation and success among 213 students studying at Usak University. A total of 213 international students studying at Usak University, including 151 males and 62 females, were selected and participated in the research voluntarily. In the study, feelings of loneliness among international students significantly impacted academic participation and success of the students. According to research, feelings of isolation and lack of aspiration for the future significantly affect the academic performance of students in complex ways. Generally, students who have aspirations for the future tend to participate and thrive in school. However, students who feel lonely and isolated tend to spend their time idly and therefore do not thrive in academic environments.
