The purpose of this study was to evaluate the effect of peak flow monitoring on asthma quality of life (QOL) for school-age children with asthma (N = 77) who participated in a 16-week asthma self-management program. QOL was measured using the Children's Health Survey for Asthma. Findings indicated significant improvement in asthma QOL from baseline to Week 16 and higher QOL scores for those with better asthma health outcomes.
