Many studies show high rates of depression in CFS patients, but usually use inappropriate questionnaires which take physical and cognitive symptoms as an indication of depression. Hence actual rates are difficult to even guess at. So the one item in this questionnaire is a simple question: Are you depressed? A diagnosis of depression is not sufficient, unless you agree that you feel depressed. If you are not depressed, but only because of ongoing treatment/medication for depression, then please answer "yes". I realize the options are very dichotomous, but please select the answer which you feel is most accurate most of the time.
