Effect of Grit, Positive Psychological Capital, and Nunchi on College Life Adjustment among Dental Hygiene Students
Abstract
Objective: This study examined the effects of grit, positive psychological capital, and nunchi use on college life adjustment among dental hygiene students and provided basic data for developing intervention programs. Methods: Data were collected from 193 dental hygiene students between March 3 and March 16, 2026. Data were analyzed using IBM SPSS 23.0 software. The collected data were analyzed using the t-test, one-way analysis of variance ANOVA, Pearson’s correlation, and multiple regression. Results: The mean score of college life adjustment was 3.57 out of 5. This was significantly higher among third-year students, those satisfied with their peer relationships, those who selected their majors for employment prospects, and those who were satisfied with their majors. College life adjustment positively correlated with grit, positive psychological capital, and nunchi. Multiple regression analysis identified positive psychological capital and nunchi as significant predictors, explaining 71.7% of the observed variance. Conclusions: Positive psychological capital and nunchi are key factors influencing college life adjustment among dental hygiene students. Therefore educational and extracurricular programs designed to enhance these attributes may facilitate successful adaptation to college life and foster professional competence.
