Acculturation Stressors and Academic Adjustment among Nepalese Students in South Korean Higher Education Institutions

International students are steadily increasing in South Korean higher education institutions. How well international students are adjusted academically and the relationship between acculturation stressors and academic adjustment has not yet been determined. This study aimed to fill this research gap by examining the relationship between acculturation stressors and academic adjustment among Nepalese international students in South Korean higher education institutions. The sample of the study consisted of Nepalese students who enrolled in 36 universities in South Korea. Students’ background characteristics and acculturation stressors were selected to examine the association between acculturation stressors and academic adjustment. Pearson correlation and hierarchical multiple regression were utilized. The results from the Pearson correlation revealed the negative correlation of perceived discrimination (r = −0.23, p < 0.01), perceived hate/rejection (r = −0.18, p < 0.05), perceived fear (r = −0.24, p < 0.01), and perceived cultural shock (r = −0.17, p < 0.05) with academic adjustment. Further, the hierarchical regression model revealed that perceived fear (β = −0.220, p < 0.05) had a negative association with academic adjustment. Addressing acculturation stressors among international students is essential to facilitate a positive academic environment. Mainly, perceived fear has negatively affected students’ academic adjustment. Based on these findings, tailored programs must be developed to curtail international students’ perceived fear.
