Background: The definition of "need of self-management" in this study was "when someone was in critical situation, he or she would start to look for the resource to help them to understand what happen and to increase their ability to care themselves". Methods: A questionnaire survey was conducted with 60 parents, who have children with moderate to severe asthma, to understand the priority of the self-management needs of education. Results: Results from this survey presented the priority of the self-management needs of education for those families as following: (1) the definition of asthma, (2) the differences between asthma and a common cold, (3) the side effect of asthma medicine for long-term using, (4) the clarification of exercise induced asthma (EIA), (5) particular information for children with asthma in daily life care, and (6) the warning signs or symptoms for asthma attack. Conclusions/ Implications for practice: The result of this study may serve as a guideline to design the self-management program for school age children with asthma.
