This study was conducted to help students in tourism-related departments make career decisions by confirming the influence of career barriers, divided into psychological and environmental factors, on career decision-making self-efficacy and career decision level in the career decision-making process of college students. For the study, a total of 300 questionnaires were distributed to four-year tourism-related departments in the Jeonbuk region from September 1 to September 20, 2023, and after collection, 288 questionnaires, excluding 12 with insincere responses, were used for analysis through SPSS Ver. 23.0 The results of the study are as follows. First, psychological and environmental career barriers had a negative impact on college students’ career decision self-efficacy and career decision level. Second, college students' career decision self-efficacy had a positive effect on their career decision level. This means that in the case of encountering a student with high psychological and environmental career barriers during the student counseling process within a university, the counseling process is primarily necessary to increase the student's self-efficacy in making medical treatment decisions, and ultimately through this, will be able to raise the level of students' career decisions.
