Epidemiological studies of peptic ulceration in the stomach and duodenum based on a standard questionnaire were carried out among the employees of a sulphur mine. The results obtained in the preliminary cross-sectional study were checked against a sample of 180 people who had undergone radiological examination of the alimentary tract. The validity of the questionnaire was then assessed by comparison of these two sets of results. The study shows that a more revealing screening test may be based on a wide range of questions rather than on a smaller set of specific questions.
