The purpose of this study was to develop a Korean College Stress Inventory (KCSI), which is designed to measure Korean college students' experiences and symptoms of career stress. Even though there have been numerous scales related to career issues, few scales measure the career stress construct and its dimensions. Factor structure, internal consistency, and concurrent validity of the KCSI scores are described. Results indicated that the internal consistency reliabilities of 4 KCSI subscale scores were reasonably high. In addition, the exploratory and confirmatory factor analyses indicated that the modified 4-factor solution seemed to provide a reasonably good fit to the data. Implications, limitations, and recommendations for future research are discussed. (Contains 3 tables and 1 figure.)
