title: Cigarette smoking and children's respiratory symptoms: validity of the questionnaire method.
abstract: Children who report that they smoke cigarettes, also report increased respiratory symptoms. Could this be an artefact of the questionnaire method? Reports of children's respiratory symptoms obtained from children and from their parents were compared. There was a significant association between these reports, although the relationship was not close. The relationship between symptoms and cigarette smoking was consistent, whichever report was used. It is concluded that the questionnaire technique is valid, and that children who smoke cigarettes are more likely than non-smokers to have respiratory symptoms.
