Abstract

The aim was to validate the Borg CR100 (centiMax) Scale® for mental stress against heart rate and blood pressure as well as the Stress-Energy Questionnaire (Kjellberg and Wadman, 2002). Subtraction with 7 and 13 respectively was used as stressors, for 11 men and 11 women. Significant differences were obtained between the stressful and rest situations for perceived stress (cMax CR100), heart rate, systolic and diastolic blood pressure (p < 0.05). A high and significant correlation was obtained between peak perceived stress (CR100) and the stress dimension of the Stress-Energy Questionnaire (r = 0.81, p < 0.001). A moderate, but non-significant correlation was obtained with heart rate (r = 0.41, p = 0.056) and a rather strong and significant correlation was obtained with diastolic blood pressure (r=0.48, p=0.025). The results show that the CR100 Scale functions well to measure mental stress.
