Data Analysis
The recorded content of the 24-hour asthma diaries was carefully examined and summarized by two researchers. Diary data were analyzed and described for each category including symptoms, feelings, activities and medication. The digitally recorded audio data were listened to by two project nurses in order to identify and annotate each eligible asthma symptom (e.g., coughing, wheezing, shortness of breath, throat clearing) for individual participants. A randomly selected sample of annotated symptom sounds were verified by consensus among three clinicians, including a nurse practitioner, a pediatrician and a pulmonologist. Subsequently, the annotated asthma symptoms for each participant were used to confirm self-reported symptoms provided in the asthma diaries. The list of medications reported in the diary was compared with the list that the research team compiled through the review of the medical record of each participant. The percent agreements between the diaries and medical records in each type of medications were computed
