Prior studies show the relationship between perfectionism and insomnia, and the detrimental effects of insomnia on performance, job satisfaction, self-control, organizational citizenship behavior, and interpersonal deviance. In the present study, we hypothesize that perfectionism has a significant impact on task performance. However, the relationship between the two is riddled by daytime sleepiness. The indirect effect of perfectionism on performance through daytime sleepiness is contingent upon the perfectionism level of an individual. Empirical investigation of the hypothesized relationships was conducted on four professional groups such as Consultants, Academicians, Marketing Managers and Technical professionals. A total no. of 419 responses were collected through questionnaire administration. Data was analyzed using SPSS, AMOS (version-22) and Process Macro for SPSS (2013). Results indicate that Self-oriented and Other-oriented perfectionism significantly predicts daytime sleepiness. Both perfectionism and daytime sleepiness are significant predictors of task performance. The mediation effect of daytime sleepiness on task performance significantly depends on the level of perfectionism of the participants. Grounded upon the study results, implications for future research are discussed.

完美主义者？你不需要睡觉：白天嗜睡和任务表现的相互作用

先前的研究表明完美主义与失眠之间的关系，以及失眠对绩效、工作满意度、自我控制、组织公民行为和人际偏差的不利影响。在本研究中，我们假设完美主义对任务绩效有显着影响。然而，两人之间的关系充满了白天的困倦。完美主义通过白天嗜睡对表现的间接影响取决于个人的完美主义水平。对四个专业群体进行了假设关系的实证调查，例如顾问、院士、营销经理和技术专业人员。总没有。通过问卷管理收集了 419 份回复。使用SPSS对数据进行分析，AMOS (version-22) 和 Process Macro for SPSS (2013)。结果表明，自我导向和他人导向的完美主义显着预测白天的嗜睡。完美主义和白天嗜睡都是任务绩效的重要预测因素。白天嗜睡对任务绩效的中介作用显着取决于参与者的完美主义水平。基于研究结果，讨论了对未来研究的影响。
