A test or system for detection of increased/excessive fatigability and as a screening tool for on- or up-coming depression, and Chronic Fatigue Syndrome. Fatigue is dissected into components including general feelings, activity, and emotions, each expressed through sets or pairs of opposite feelings. Between the opposite feelings there is a scale, from which the person will select the most applicable point that best reflects the person's present feelings. The scale is scored, and based on the score it is determined whether to perform the test again, or to evaluate for depression. If the test is performed again, need for further evaluation is determined from that score.
