Objectives: This study explored how sense of belonging, satisfaction with one’s major, and resilience influence the development of career identity among dental hygiene students. Methods: A total of 180 dental hygiene students in South Korea were surveyed using a structured questionnaire. Data were analyzed using t-tests, ANOVA, Pearson’s correlation, and multiple regression with SPSS. Results: Career identity was significantly and positively correlations with sense of belonging (r=0.399), major satisfaction (r=0.577), and resilience (r=0.485). Multiple regression analysis identified clinical practice satisfaction (β=-0.177, p=0.004), sense of belonging (β=-0.183, p=0.034), resilience (β=0.326, p<0.001), and major satisfaction (β=0.400, p<0.001) as significant predictors, collectively explaining 41.9% of the variance in career identity. Conclusions: In order to strengthen career identity among dental hygiene students, it is crucial to cultivate a sense of belonging within clinical environments, enhance major satisfaction, and promote resilience. The implementation of integrated career guidance and emotional support systems is recommended.
