The authors examined career-related uncertainties perceived by college students in Taiwan. Five hundred thirty-two Taiwanese students responded to a free-response instrument containing 3 questions related to career uncertainties: (1) the sources of career uncertainty; (2) the experiences at the moment of feeling uncertainty; and (3) coping efficacies toward the uncertainty. Responses were sorted into categories within each question based on the grounded theory methodology (B. G. Glaser & A. L. Strauss, 1967). A hypothetical model was developed to describe college students' perceptions of career uncertainties, experiences of feeling uncertainty, and coping efficacy toward the uncertainty.
