The purpose of this dissertation is to study stress, anxiety, and depression factors that are influencing the campus adjustment of Korean students. In particular, I tried to discover what internal factors exist that allow Korean students to adapt to campus life, including while in high risk situations. Also I found ways to raise ability of adjustment into campus life by identifying the factors which are more influential between stress, anxiety, and depression factors. The result of the study are as follows; First, mental factors are more important than risk factors when adapting to campus life. Significantly, there should be a large number of campus external factors in place to help Korean students adapt to life in the campus. Students who live in a tight group require the improvement of their environment to retain a trusting relationship and positive outlook within the campus organization, and within their daily lives in order to cultivate a positive relationship with the other students and seniors. Campus consultation systems must be working efficiently, and students should have more stable lives to help prevent accidents during their campus. The obsessive compulsive that risk factors are really high should be adapted in campus life, Risk factors, obsessive compulsive can raise the stress levels of students and can cause maladjustment to campus life. We need to improve various consultation programs, such as mental health care and human nature education, in order to prevent students' maladjustment to their present condition. We need to teach students to view their problems with a positive outlook through programs such as these. If students are in a situation where many risk factors are present, I was able to check these risk factors effect on the students adjustment by using the buffer of external factors. Moreover, support from other students shows the most influence among campus environment factors, meaning we should be aware of the importance of their consideration, attention, encouragement, and support.
