Evaluation of the ATS respiratory diseases questionnaire among French-speaking silicon carbide workers.
The American Thoracic Society (ATS) respiratory disease questionnaire for adults was translated by two fluently bilingual Quebec health professionals into simple, everyday French easily understood by an adult population of varying age and educational background. After independent assessment by professional translators, it was field-tested on 165 silicon carbide production workers. Responses to the ATS cough questions were significantly related to those obtained by a semiquantitative estimate of cough frequency. ATS questions on cough and phlegm were significantly associated with the physical sign of productive cough on request. A significant association was found between answers to questions on mild or moderate breathlessness and self-evaluation of breathing on a linear scale. Workers with cough, wheeze, or breathlessness had significantly lower percent-predicted FEV1, and FEV1 decreased as the severity of breathlessness increased. Highly significant, dose-dependent associations with current cigarette smoking habit were found for cough, phlegm and wheeze. Significant, dose-dependent associations with phlegm, wheeze and mild breathlessness also occurred with exposure to sulfur dioxide. All of these relationships are similar to findings from studies of English-speaking populations. Minor problems with the original English ATS questionnaire were discovered on translation, and suggestions for improvements were made. Preliminary experience with this French translation suggests that it is a useful, comparable version of the English ATS questionnaire.
