A multiple study mixed methods research design was used to examine how gifted English as a Foreign Language (EFL) high school students in Vietnam form their career intentions. In the first study, interview data collected from 25 participants were analyzed using grounded theory to develop models that describe the formation of career intentions. In the second study, survey data collected from 512 participants were analyzed using structural equation modeling procedures to quantitatively test and refine the qualitative models developed in the first study. In the final third study, structural equation modeling was again used on data collected from 602 participants using a refined survey to quantitatively retest and refine the models developed in both of the earlier two studies. The finally accepted optimal model highlighted the importance of career interest, career self-efficacy, and career prospects in the formation of the career intentions of gifted EFL high school students in Vietnam.

一项采用多种研究混合方法的研究设计用于检查越南资优英语作为外语（EFL）高中生如何形成其职业意向。在第一项研究中，使用扎根理论分析了从25名参与者那里收集的访谈数据，以开发描述职业意图形成的模型。在第二项研究中，使用结构方程建模程序分析了从512名参与者中收集的调查数据，以定量测试和完善在第一项研究中开发的定性模型。在最后的第三项研究中，结构方程建模再次用于从602名参与者中收集的数据，并使用改进的调查定量地重新测试和改进了前两项研究中开发的模型。
