These questions are about how you feel and how things have been with you during the past month. For each question, please circle one number for each question that comes closest to the way you have been feeling.
Score the number circled, except items 1 and 3, which are reversed (i.e., 5, 4, 3, 2, 1), then take the mean of the five items. If two consecutive numbers are circled for one item, code the more conservative (i.e., less energy or more fatigue). If two non-consecutive items are circled, do not score the item. The scales' score is the mean of the 5 items. If more than two items are missing, do not score this scale. Range is 0-5; higher score indicates more energy.
Tested on 1,130 subjects with chronic disease. N=51 for test-retest.

This scale was adapted from the Medical Outcomes Study. Items should be scrambled among other items using the same response categories, if possible (e.g., Health Distress scale). We have found that items 1,3, and 4 change much more than the other two items. In other words one can be less fatigued without having much more energy.
