title: [Validation of an asthma knowledge questionnaire].
abstract: BACKGROUND
  A patient's knowledge of his disease and its treatment is an essential part of the evaluation of an educational process. It is useful therefore to use a rapid, easy and valid means of collecting the information necessary to produce an educational programme adapted to the needs of the patient.
  
  
  METHODS
  Following a review of the literature an initial questionnaire was constructed. It included four domains: biomedical, signs and symptoms of severity, general knowledge and treatment. The questionnaire was administered to 73 asthmatics in order to assess its clarity and comprehensibility. It was then reviewed and modified in both format and content by 10 French experts. The revised questionnaire was completed by 108 asthmatics distributed throughout 10 French respiratory centres, a group of 83 non-asthmatic subjects and 203 sixth year medical students at the Bordeaux University School of Medicine.
  
  
  RESULTS
  The mean scores were: 19 for the non-asthmatics (range 2-36), 25.7 for the asthmatics (range 4-38) and 32.9 for the students (range 17-40), p 0.0001. The questionnaire was shown to be discriminating with good reliability and reproducibility: alpha Cronbach coefficient=0.82; intra-class correlation coefficient=0.70.
  
  
  CONCLUSIONS
  This study has validated a French language asthma knowledge questionnaire.
