Abstract
The purpose of this study was to develop and determine the validity of a patient-completed questionnaire that assesses metered-dose inhaler (MDI) technique. Self-reported MDI technique was compared to observed technique. The questionnaire included nine steps for MDI use, with two to three response choices for each step. A total of 159 patients were studied. Direct observation revealed that greater than 82% of patients exhibited inadequate technique (more than two out of nine steps incorrect). The mean percentage agreement between the questionnaire and observation was 77.4%. Questionnaire results where in higher agreement with observation when patients performed correct MDI technique.
