摘要

背景:同时完成一系列任务所需的心理资源量被视为心理工作量(MWL)。工作场所的精神工作量过高或过低通常与精神疲劳、工作绩效下降、人为失误,甚至长期有害健康有关。在各种 MWL 评估技术中,问卷调查等结果测量方法在工作场所环境中更为简便实用。我们旨在对目前普遍提倡和使用的三种问卷进行比较。材料与方法用于评估工作负荷的三种常见的不同结果测量方法是 NASA 任务负荷指数(NASA-TLX)、主观工作负荷评估技术(SWAT)和 CarMen-Q 工作负荷问卷。其中,NASA-TLX 以其六个分量表而闻名,在工业和官方工作场所被广泛使用。SWAT 是最简单的一种,有三个维度。NASA-TLX 的灵敏度较高,尤其是在最低工作负荷较低的情况下,因此是一种较好的方法。CarMen-Q 问卷是一种新的问卷,有 29 个项目和 4 个分量表,主要针对认知工作量和心理疲劳。结论与 NASA-TLX 和 CarMen-Q 问卷相比,SWAT 是最简单、灵敏度较低的测量方法。相比之下,NASA-TLX 是一种广泛使用且更为人熟知的工作负荷评估工具。

Common Subjective Mental Workload Assessment Measures: Advantages and Disadvantages
Background: The amount of mental resources required to perform simultaneously a series tasks is considered as mental workload (MWL). High and Low mental workload in the workplace is usually associated with mental fatigue, decreased performance, human error, and even harmful long-term health effects. Among the various MWL assessment techniques, the outcome measures such as questionnaires are easier and more practical in workplace settings. We aimed to compare the three current commonly advocated and used questionnaires. Material and Methods: Three common different outcome measures for evaluation of the MWL are NASA Task Load Index (NASA-TLX), Subjective Workload Assessment Technique (SWAT), and the CarMen-Q workload questionnaire. Among them the NASA-TLX is well known and more popular with six subscales that are used extensively in industrial and official workplaces. SWAT is the simplest one with three dimensions. The NASA-TLX is preferable method because of its higher sensitivity, especially in low MWL conditions. The CarMen-Q questionnaire is a new questionnaire with 29 items and 4 subscales that focuses on cognitive workload and mental fatigue. Conclusion: SWAT is the simplest and less sensitive measure than the NASA-TLX and CarMen-Q questionnaires. In contrast, the NASA-TLX is widely used and more known instrument for MWL evaluation.
