Abstract
BACKGROUND: An efficient asthma self-management for adolescents must be based on adolescents' needs, increase self-efficacy and adherence to treatment. The effects of such program are likely be dose dependent. AIM: To examine the impact of the dose-effect of multiple components on an asthma self-management program for adolescents aged 12-18 years in Taiwan. METHODS: A scoring system was developed to classify intervention groups into high- (19-23), medium- (11-18) and low (< 11) dose according to the number of components completed by participants. The impacts of the dose level on outcomes of asthma self-efficacy, prevention behaviors, asthma medication adherence, and asthma symptoms were examined. RESULTS/CONCLUSION: Our results suggest that a high dose of the intervention can improve adolescents' self-efficacy, asthma prevention behavior, and medication adherence.
