这项研究的目的是探讨在相对压力和认知要求较高的工作场所环境中，茶、咖啡和其他饮料的消费与个人的工作表现和情绪之间的关系。采用自然主义的横断面研究设计，95 名专业和学术人员在十个工作日内每天四次记录他们的饮料摄入量并完成员工的工作表现（疲劳/疲惫、正念、工作投入）、主观工作表现、情绪、与工作相关的压力和恢复情况的自我报告。使用多级建模来分析数据，以符合数据的层次结构。喝茶与提高工作绩效和减少疲劳有关，尤其是在不喝牛奶或糖的情况下。饮用不含咖啡因的饮料与工作后的放松和恢复程度增加有关。相比之下，茶和其他含咖啡因的饮料会增强夜间恢复和早晨情绪对白天正念的负面影响。研究结果表明，饮料摄入可能有助于优化与工作相关的心理状态和表现。 (C) 2011 Elsevier Ltd. 保留所有权利。
The aim of this research was to examine relationships between tea, coffee and other beverage consumption and associates of work performance and mood among individuals in relatively stressful and cognitively demanding work-place settings. Using a naturalistic, cross-sectional study design, 95 professional and academic staff logged their beverage intake and completed self-reports of associates of work performance (fatigue/exhaustion, mindfulness, work engagement), subjective work performance, mood, work-related strain and recovery four times daily during ten working days. Data were analysed using multilevel modelling in keeping with the hierarchical structure of the data. Tea consumption was associated with increased perceived work performance and reduced tiredness, especially when consumed without milk or sugar. Consumption of non-caffeinated beverages was associated with increased relaxation and recovery from work. In contrast, tea and other caffeinated beverages were found to enhance the negative effects of evening recovery and morning mood on mindfulness during the day. The findings suggest that beverage intake may have a role in optimising work-related psychological states and performance. (C) 2011 Elsevier Ltd. All rights reserved.
