To ensure diverse representation of Latino families and healthcare settings, the sample will be recruited from two school-based health clinics and one clinical practice site in Phoenix, AZ, and two inner-city hospital asthma clinics in the Bronx, NY. Approximately 300 families will be recruited and enrolled from the asthma/allergy and general pediatric clinics and ER at Jacobi Medical Center and North Central Bronx Hospital (N= 150), Phoenix Children's Hospital Breathmobile (N= 75), and the two school-based health clinics in Phoenix (N= 75).
