本研究目的為探討積極性人格與幸福感的關係，另瞭解與職涯適應力在其中之中介效果為何。本研究共有221自願外派至臺灣工作者完成紙本或線上之問卷。大部分參與者（89.1%）來自亞洲國家，其中有114名是男性。參與者的平均年齡為30.29歲，標準差為6.92。本研究使用SPSS 23.0，AMOS 22.0及Mplus 8.0以分析有效問卷。本研究的結果顯示，積極性人格與幸福感有正向相關，其中職涯適應完全中介其二者之關係。故此，有積極人格的自願外派人員，藉由其職涯適應力在外派國家會有較高的幸福感。

Drawing from career construction theory, the purpose of this study was to examine the relationship between proactive personality and subjective well-being with the mediating effect of career adaptability. The valid sample was 221 self-initiated expatriate (SIEs) working in Taiwan by collecting the paper-based or online questionnaires. Most of the participants (81.9 %) come from Asia countries, 114 of them were male, and average of age was 30.29 (SD = 6.92). To test the hypotheses, SPSS 23.0, AMOS 22.0, and Mplus 8.0 were used to analyze the valid data. The results demonstrated that proactive personality was positively related to subjective well-being and career adaptability fully mediated this relationship. This study contributed to understand that proactive SIEs experienced better subjective well-being via their adaptability on the career in the host country.
