Resum

Objective: The present research evaluates several psychometric properties of three multidimensional subjective workload assessment instruments: NASA-TLX, SWAT and WP. Material and methods: Thirty six subjects performed two laboratory tasks separately and simultaneously. A discrete Sternberg memory task and a continuos tracking task were used. Results: The results showed that: a) the three instruments were sensitives to the difficulty task manipulations, but WP was the best; b) diagnosticity of WP and SWAT was clearly superior to the obtained using TLX, and c) convergent validity of the three instruments was elevated
