In this study we investigate the antecedents of career exploration. We apply the perspectives of Flum and Blustein [Flum, H., & Blustein, D. L. (2000). Reinvigorating the study of vocational exploration: A framework for research. "Journal of Vocational Behavior, 56", 380-404] for the first time in Hong Kong, and we also test culture-specific factors in exploration. A quantitative research study was conducted with Chinese students from a university in Hong Kong over a period of up to six months to examine relationships between career exploration and its antecedent variables. Data were obtained from a cross-sectional sample of 271 students and a longitudinal sample of 101 students who participated in either a student internship or a series of career seminars. The results demonstrated that relational support and prior career exploration were related consistently to career exploration as hypothesized, but the claim that achievement motivation is an antecedent of exploration received only limited support. The framework of Flum and Blustein [Flum, H., & Blustein, D. L. (2000). Reinvigorating the study of vocational exploration: A framework for research. "Journal of Vocational Behavior, 56", 380-404] was found very relevant in our conceptualization and analysis of career exploration in the Hong Kong context. Implications of this study are discussed and suggestions are made to further extend career exploration research in Hong Kong and other Chinese societies. (Contains 4 tables.)
