During last 12 months, have you experienced any of the following…
For this set of questions, the interviewer must read out a series of symptoms and determine if the respondent had any of those symptoms in the last 12 months. The point of asking symptom-related questions is to screen those individuals who might have a specific health condition or disease. Because there could be a number of symptoms that characterise a given health condition, and because some symptoms may be common to different conditions, it is important that the interviewer probe for each symptom to see whether the respondent may have an active disease. It is also important that the time period for the symptoms (in the last 12 months) be clearly understood by the respondent and not confused with other time frames used in this section (such as "ever" and "the last 2 weeks").
During last 12 months, have you had a period lasting several days when you have been feeling your energy decreased or that you are tired all the time?
Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
The emphasis is on a period that lasted several days (not just one or two days), where the person felt having had less energy than usual and experienced marked tiredness even after minimum effort.
If the answer to Q6028, Q6029, Q6030 is “no”, the interviewer may skip the following four questions and go to question 6035, with the understanding that Q6031-Q6034 will be not applicable or answer is the negative.
