Description

A standardized six-subscale self-report assessment developed by NASA for measuring perceived workload across mental, physical, temporal, performance, effort, and frustration dimensions.

Components

  • NASA-TLX multidimensional workload questionnaire used as a common measurement instrument across design activities: NASA-TLX is a multi-dimensional rating procedure that assigns a total workload score based on a weighted average of six sub-scales: mental demand, physical demand, temporal demand, performance, effort, and frustration level. Its application has two sequential phases: weighing, consisting of 15 binary comparisons among the six dimensions after task execution, and estimation, in which the individual rates each dimension on a scale from 0 to 100 immediately after task completion. In this study it was adopted as an outcome evaluation instrument for comparing different design phases and activities, with 133 questionnaires delivered. (Christopher Nikulin et al. (2019))
