Computer use and, more specifically, the administration of tests and materials online continue to proliferate. A number of subjective, self-report workload measures exist, but the National Aeronautics and Space Administration-Task Load Index (NASA-TLX) is probably the most well known and used. The aim of this paper is to consider the workload costs associated with the computer-based and paper versions of the NASA-TLX measure. It was found that there is a significant difference between the workload scores for the two media, with the computer version of the NASA-TLX incurring more workload. This has implications for the practical use of the NASA-TLX as well as for other computer-based workload measures.
计算机的使用，更具体地说，在线测试和材料管理的应用持续增多。虽然存在一些主观的自我报告工作量测量方法，但美国国家航空航天局任务负荷指数（NASA-TLX）可能是最广为人知且使用最多的。本文旨在探讨与基于计算机和纸质版的NASA-TLX测量相关的工作量成本。研究发现，两种媒介的工作量得分存在显著差异，基于计算机版的NASA-TLX产生的工作量更多。这对NASA-TLX的实际应用以及其他基于计算机的工作量测量方法都有影响。
