Strop color and word test
A modified version of the SCWT was used to promote mental stress in the study participants. The test started with 3-min baseline, and then the participants were presented with a sequence of words of different colors (red/green/blue) printed in either same (congruent condition) or different colors (incongruent condition). Participants were requested to respond the color of the ink rather than the words meaning [HR and BP were measured in 1-min intervals during the test, and SBP, DBP and HR reactivity to the SCWT were calculated as the absolute changes (delta changes – Δ) from mean baseline to their highest values achieved during the stress phase (usually within the 2nd of 3rd minute of stress).
