To determine the importance of the questions, they were put to 100 participating asthmatic patients. The number of questions was reduced by consensus taking into account the importance given to each question by these patients. A further 25 patients participated in the assessment of reliability and sensitivity. The questionnaire was administered 5 times: twice before and 3 times after an educational intervention. The direct and indirect test-retest consistency (κ statistic) and the overall κ value were determined.
