Abstract (300 words maximum)
A performance comparison between NASA-TLX and SURG-TLX workload measurements
Undergraduate Student: Isabella Duque
Research Mentor(s): Dr. Luisa Valentina Nino
Mental workload has gained attention in the workplaces since technology has recently become more common. Mental workload is a concept with multiple dimensions, such as stress or time demand, that includes qualities about the task, the operator, and the workplace environment. NASA-TLX and SURG-TLX are mental workloads measurement tools. The NASA-TLX is currently the most used tool to measure workload and is a questionnaire of six dimensions: mental demand, physical demand, temporal demand, performance, effort, and frustration. The SURG-TLX is a recently developed tool that measures mental workload in the medical field, especially in the surgery area. It also consists of six dimensions: mental demands, physical demands, temporal demands, task complexity, situational stress, and distractions. It is important to know that SURG-TLX has the additional dimensions of complexity, situational stress, and distractions dimensions. The objective of this research is to analyze the data of thirty-two participants in a study where they were exposed to external psychosocial factors that generated different levels of stress, mental, and physical reactions. The NASA-TLX and SURG-TLX were used to measure those reactions. The data collected from the two tools will be compared to explore strengths, weaknesses, similarities, differences, and correlation, and to determine if SURG-TLX and its dimensions are more appropriate to use in future research in the medical field.
