Building career decision self-efficacy (CDSE) and engaging in career exploratory behavior (CEB) have been identified as key adaptive career behaviors that promote successful career choice and development among adolescents and young adults. Using the RI-CLPM and a five-wave dataset gathered from first-year exploratory college students (N = 833), this study examined temporal predominance between CDSE and CEB and their effects in mediating the relations of personality traits to career decidedness. At the within-person level, the bidirectional model revealed a reciprocal relation from T2 CDSE to T5 CEB for the entire sample. A similar temporal pattern also emerged for European American students and female students, whereas the baseline model was retained for male students and students of color. At the between-person level, random intercepts of CDSE and CEB were found to mediate the relations of T1 extraversion and emotional stability to T5 career decidedness for the entire sample. While the mediating effect of CDSE was significant and tended to be larger than that of CEB across racial/ethnic and gender subgroupings, mediational pathways of personality traits → CEB → career decidedness varied by race/ethnicity. This study provides evidence for theory-based hypotheses regarding how CDSE and CEB relate to each other temporally within the student and how the two variables channel the effects of personality traits on career decidedness between students. It also offers practical implications for including CDSE and CEB in career interventions designed to facilitate career development of exploratory students of different racial/ethnic and gender backgrounds during their initial transition to college.

建立职业决策自我效能（CDSE）和参与职业探索行为（CEB）已被确定为促进青少年和年轻人成功职业选择和发展的关键适应性职业行为。使用 RI-CLPM 和从一年级探索性大学生收集的五波数据集 ( N = 833），本研究考察了 CDSE 和 CEB 之间的时间优势及其在调节人格特质与职业决策关系中的影响。在人体内层面，双向模型揭示了整个样本从 T2 CDSE 到 T5 CEB 的相互关系。欧裔美国学生和女学生也出现了类似的时间模式，而男学生和有色人种学生则保留了基线模型。在人与人之间的层面上，发现 CDSE 和 CEB 的随机拦截可以调节整个样本的 T1 外向性和情绪稳定性与 T5 职业决策的关系。虽然 CDSE 的中介效应显着，并且在种族/族裔和性别亚组中往往比 CEB 的中介效应更大，人格特质的中介路径 → CEB → 职业决策因种族/民族而异。这项研究为基于理论的假设提供了证据，这些假设涉及 CDSE 和 CEB 在学生内部如何在时间上相互关联，以及这两个变量如何引导人格特质对学生之间职业决策的影响。它还为将 CDSE 和 CEB 纳入职业干预措施提供了实际意义，这些干预措施旨在促进不同种族/民族和性别背景的探索性学生在进入大学的最初过渡期间的职业发展。
