It is shown that the state of working people, determined using the WAM technique, (well-being, activity, mood) has statistically significant correlation with the results of instrumental measurements in terms of changes in the physiological state of the same workers. It is proposed to use the WAM test as an independent method for determining the functional state of workers. The purpose of this work was to determine the ratio of the functional state of workers according to the instrumental assessment, on the one hand, and self-assessment of their state, on the other.
