Polychronicity refers to the preference of some individuals to structure their time in order to deal with multiple tasks simultaneously in a short period of time. Past research regarding the correlation between individual polychronicity and performance presented distinct arguments. Although most studies supported a positive correlation with performance, empirical findings showed inconsistent results, indicating the presence of other influencing factors. According to the person–environment fit theory and self-determination theory, the effect of polychronicity on job performance was verified and the mediation effect of well-being was tested in this study. Dual-mode questionnaires were collected from 532 subordinators and their direct supervisors in 98 chain restaurants and hierarchical regression analysis was performed to test the research hypotheses. The results showed that polychronicity positively affected well-being, that is, well-being was a full mediator between polychronicity and job performance. This study provides valuable insight for managers to understand employee polychronicity and, in turn, improve their well-being, which could help improve job performance.

从人与环境的适应角度探讨多时性与工作绩效之间的联系-幸福的中介作用。

多时性是指某些人倾向于安排他们的时间，以便在短时间内同时处理多个任务。过去有关个体多时性与绩效之间关系的研究提出了不同的论点。尽管大多数研究都支持与绩效呈正相关，但经验发现表明结果不一致，表明存在其他影响因素。根据人与环境的适应理论和自我决定理论，验证了多时性对工作绩效的影响，并检验了幸福感的中介作用。从98家连锁餐厅的532名下属及其直接主管中收集了双模式问卷，并进行了层次回归分析以检验研究假设。结果表明，多时性对幸福感产生积极影响，也就是说，幸福感是多时性与工作绩效之间的完全中介。这项研究为管理人员了解员工的多元性提供了宝贵的见解，进而改善了他们的幸福感，这可以帮助改善工作绩效。
