本研究旨在探討開放性人格與適應性績效之關係,是否會受學習敏捷性與恆毅力之中介。適應性績效是個人為因應環境、工作的要求來修正其行為的工作績效。學習敏捷性指的是在新的、艱難的或不同的條件下,表現出學習新能力的意願和能力(Lombardo & Eichinger, 2000)。恆毅力指的是為達成長期目標所具備的毅力與熱情(Duckworth et al., 2007)。透過問卷調查法,共計回收320份來自不同行業員工之問卷。研究結果顯示,學習敏捷性可中介開放性人格與適應性績效之關係,但是恆毅力與適應性績效僅有低到中度相關。;The present study aims to explore the relationship between openness to experience and adaptive performance, with regards to the possible mediation by learning agility and grit. Adaptive performance is a type of job performance that an individual adapts to its environmental and work demand. Learning agility refers to “the willingness and ability to learn new competencies in order to perform under first-time, tough, or different conditions” (Lombardo & Eichinger, 2000). Grit refers to “perseverance and passion for long-term goals” (Duckworth et al., 2007). A total of 320 questionnaires from working adults were collected and analyzed. Results show positive correlation among openness to experience and adaptive performance. While learning agility is able to mediate such relationship, the mediation of grit is not present, probably due to low to moderate correlations with adaptive performance.
