Purpose: The purpose of this study was to examine the relationship among self-efficacy, career attitude maturity, and campus life satisfaction in nursing college students. Method: A total of 277 students agreed to participate in this study from 1 May 2016 to 31 May 2016. Data analysis included t-test, ANOVA, Scheffe's test, and multiple regression using the SPSS/WIN 18.0 program. Results: The results of the analysis revealed a positive correlation between campus life satisfaction and career attitude maturity (r=.316, p=.001); between campus life satisfaction and self-efficacy (r=.256, p=.001); and between self-efficacy and career attitude maturity (r=.469, p=.001). Career attitude maturity had the highest R-squared value of 10% (${\beta}=.22$) for campus life satisfaction, while peer relationships had an R-squared value of 2% (${\beta}=-.18$), residence type of 2% (${\beta}=.14$), and self-efficacy of 1% (${\beta}=.14$), for a total R-squared value of 15%. Discussion: Given these results, individual counseling is recommended to improve campus life satisfaction by helping college students to acquire the skills to foster good interpersonal relationships, self-efficacy, and a positive view of their future vocation. Furthermore, it is essential for an educational environment to support students to ensure that after graduation they become fully-fledged members of society with a sense of pride in their profession.
