Question pretext
During the last 12 months, have you experienced 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").
Interviewer instructions
The purpose of this question is to distinguish feeling of tightness in the chest caused by asthma from other types of health problems. The episode can last a few minutes or several hours. This question asks for specific reference to the time and the situation when the symptom occurs. It is characteristic for asthma to cause the feeling of tightness in the chest upon waking up.
