The purpose of this study was to provide initial results on the development and validation of the Career Futures Inventory (CFI), a new 25-item measure of positive career planning attitudes. Items were originated using the rational method. Results from an item analysis of scale homogeneity and exploratory factor analysis in a sample of 690 undergraduates from a large midwestern university revealed three subscales: Career Adaptability, Career Optimism, and Perceived Knowledge. Confirmatory factor analyses indicated that the three-factor model provided an excellent fit to the data. Additional analyses established high internal consistency, temporal stability, and construct validity through examination of correlates with dispositional optimism, Big Five personality characteristics, generalized problem solving, vocationally relevant self-efficacy, interests, and numerous career-relevant attitudes and outcomes. Implications for future research and counseling practice are discussed.
