The purpose of this study was to classify university students in emerging adulthood according to grit(effort vs. interest) and passion mindset(fix vs. growth), and to identify if there are differences in psychological characteristics such as depression, anxiety and life satisfaction and career adaptability between the profiles. To this end, we used Latent Profile Analysis(LPA) for university students age 18 between 25. As the result of analysis, we determined 4 distinct profiles are most appropriate classification. The profile1(LP1, 22.2%) had high levels of grit and passion growth mindset. The profile2(LP2, 63.8%) showed average levels in both grit and passion mindset. The profile3(LP3, 8.8%) had a low level of grit and a high level of passion fixed mindset. At last, the profile4(LP4, 5.1%) showed a low level of grit and a high level of passion growth mindset. As the result of examining differences in psychological characteristics and career adaptability, the profile1 was most adaptive contrasting to the profile 3. Those findings suggest grit has more effect on psychological characteristics and passion growth mindset in career adaptability. Therefore, it is suggested the passion growth mindset and grit need to be considered together as an intervention to enhance the individual’s comprehensive psychological well-being and to increase the level of adaptation for career adaptation.
