Psychophysiological Stress Indicators of Heart Rate Variability and Electrodermal Activity With Application in Healthcare Simulation Research.

Psychological stress arises from a stressor placed on an individual that leads to both emotional and physiological responses. The latter is referred to as psychophysiological stress. Healthcare simulation provides a platform to investigate stress psychobiology and its effects on learning and performance. However, psychophysiological stress measures may be underused in healthcare simulation research. The inclusion of such measures with subjective measures of stress in healthcare simulation research provides a more complete picture of the stress response, thereby furthering the understanding of stress and its impact on learning and performance. The goals of this article were to review 2 commonly used psychophysiological stress measures involving heart rate variability and electrodermal activity reflecting sweat gland activity and to demonstrate their utility in an example pilot study in healthcare simulation research.
