Objective : This study aims to investigate the correlations among contact experiences with the elderly, knowledge about dementia, and attitudes toward dementia among Vietnamese international students residing in Korea. It seeks to serve as foundational research for improving dementia awareness among international students and developing educational programs. Methods : An online survey was conducted on 73 Vietnamese international students enrolled in Korean language training programs and degree programs in Gwangju and Jeollanam-do. The collected data were analyzed using descriptive statistics and Spearman's correlation analysis with SPSS 25.0. Results : The quality of international students' contact experiences with the elderly was 9.92 points, their knowledge of dementia was 7.08 points, and their attitudes toward dementia were 36.26 points. Positive contact experiences with the elderly showed a significant positive correlation with emotional attitudes toward dementia, while knowledge of dementia showed a significant positive correlation with behavioral attitudes. Conclusion : This study confirmed that an integrated approach is necessary to positively change the attitudes of Vietnamese international students toward dementia, including not only fragmented knowledge education but also providing opportunities for positive contact with the elderly to form positive relationships. Future studies should be expanded to include international students of various nationalities and confirm the need for educational programs and vocational training to improve international students' awareness of dementia.
