Abstract
Background
The National Aeronautics and Space Administration-Task Load Index (NASATLX) is a subjective instrument for measuring cognitive load. Originally designed for aviation, it has proven a valid and reliable instrument across disciplines. Despite extensive use, its ability to measure cognitive load in group and individual nursing simulation has yet to be explored.
Methods
This secondary analysis investigates NASA-TLX psychometric properties among 488 surveys completed by learners from a Bachelor's nursing program during individual and group simulation. Psychometric tests included item analysis, Cronbach's alpha, inter-item correlations, and exploratory factor analysis.
Results
NASA-TLX demonstrated acceptable reliability and validity in individual simulation; however, there was less reliability in group simulations.
Conclusion
Administration variances across individual and group simulation impact NASATLX validity and reliability.
期刊介绍：
Clinical Simulation in Nursing is an international, peer reviewed journal published online monthly. Clinical Simulation in Nursing is the official journal of the International Nursing Association for Clinical Simulation & Learning (INACSL) and reflects its mission to advance the science of healthcare simulation.
We will review and accept articles from other health provider disciplines, if they are determined to be of interest to our readership. The journal accepts manuscripts meeting one or more of the following criteria:
Research articles and literature reviews (e.g. systematic, scoping, umbrella, integrative, etc.) about simulation
Innovative teaching/learning strategies using simulation
Articles updating guidelines, regulations, and legislative policies that impact simulation
Leadership for simulation
Simulation operations
Clinical and academic uses of simulation.
