Surrogate decision makers (SDMs) of the critically ill experience intense emotions and transient states of decision fatigue. These factors may increase the cognitive load experienced by electronic decision aids. This cross-sectional study explored the associations of emotion regulation (expressive suppression and cognitive reappraisal) and decision fatigue with cognitive load (intrinsic and extraneous) among a sample of 97 SDMs of the critically ill. After completing subjective measures of emotion regulation and decision fatigue, participants were exposed to an electronic decision aid and completed a subjective measurement of cognitive load. Multiple regression analyses indicated that decision fatigue predicted intrinsic cognitive load and expressive suppression predicted extraneous cognitive load. Emotion regulation and decision fatigue represent modifiable determinants of cognitive load among SDMs exposed to electronic decision aids.
重症患者的替代决策者（SDMs）会经历强烈的情绪和决策疲劳的短暂状态。这些因素可能会增加电子决策辅助工具所带来的认知负荷。这项横断面研究探讨了97名重症患者替代决策者样本中情绪调节（表达抑制和认知重评）及决策疲劳与认知负荷（内在和外在）之间的关联。在完成情绪调节和决策疲劳的主观测量后，参与者接触了一种电子决策辅助工具，并完成了认知负荷的主观测量。多元回归分析表明，决策疲劳可预测内在认知负荷，表达抑制可预测外在认知负荷。情绪调节和决策疲劳是接触电子决策辅助工具的替代决策者认知负荷的可改变决定因素。
