Purpose: To present the development and psychometrics of a brief asthma self‐management questionnaire for adults incorporating the five content areas considered essential for asthma self‐management by the National Asthma Education and Prevention Program. Data sources: After development of the criterion‐referenced questionnaire, determination of content validity, pilot testing, and revision, the questionnaire was administered to 305 adults with asthma. Conclusions: After exploratory principal component factor analysis, the final 24‐item questionnaire had a reliability of .69, close to the preferred reliability of .70. Implications: The questionnaire is recommended for assessing self‐management knowledge in clinical settings and for evaluation of asthma education programs.
