Abstract This study integrated trait, state, and learner perspectives to better understand the potential relationships between self-regulation in L2 writing and two personality factors (conscientiousness and neuroticism) in a university EFL context. Based on an innovative mixed methods design, data from cross-sectional and longitudinal samples were analyzed using quantitative and qualitative techniques, including structural equation modeling, visualization tools, and participant interviews. One novel finding of this study was that, from a trait perspective, conscientiousness positively contributed to self-regulation, whereas neuroticism negatively contributed to it. This analysis also supported a link between self-regulation and L2 writing. From a state perspective, in contrast, fluctuations were observed in self-regulation and personality factors over a 15-week period. Also reported are learner perspectives on self-regulation, which can offer practical insights for writing instructors and advisors. Themes included, among others: social engagement, composing processes, motivational issues, negative emotions, and rationalizing withdrawal. As a whole, this study has implications for understanding L2 writers’ complex attributes in terms of structural relations, temporal dynamics, and writing processes.

二语写作者的自我调节和个性：整合特质、状态和学习者的观点

摘要 本研究综合了特质、状态和学习者的观点，以更好地了解大学英语环境中二语写作中的自我调节与两种人格因素（尽责性和神经质）之间的潜在关系。基于创新的混合方法设计，使用定量和定性技术（包括结构方程建模、可视化工具和参与者访谈）分析来自横截面和纵向样本的数据。这项研究的一个新发现是，从特质的角度来看，尽责性对自我调节有积极贡献，而神经质对自我调节有负面影响。该分析还支持自我调节和 L2 写作之间的联系。相比之下，从国家的角度来看，在 15 周内观察到自我调节和个性因素的波动。还报告了学习者对自我调节的看法，可以为写作教师和顾问提供实用的见解。主题包括：社会参与、创作过程、动机问题、负面情绪和合理化退缩。总的来说，这项研究对于理解二语写作者在结构关系、时间动态和写作过程方面的复杂属性具有重要意义。
