Measuring asthma self-management knowledge in adults.
OBJECTIVE
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.


METHODS
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.


CONCLUSIONS
The questionnaire is recommended for assessing self-management knowledge in clinical settings and for evaluation of asthma education programs.
