The purposes of the study were threefold: (1) to construct the Chinese version of “Career Decision-making Difficulties Inventory;” (2) to investigate the career-related problems encountered by college students; and (3) to test a classification system for career decision difficulties for college students. Four hundred and sixty-seven college students completed the Career Decision-making Difficulties Questionnaire. Data obtained was analyzed by Chi-square, ANOVA, factor analysis, and ADDTREE. The results indicated the significant differences between decided and undecided students on their perceptions of career difficulties. The three-group classification system for career decision difficulties was generally speaking supported by the data in this study.
