Sample and Setting: 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. A multisite study is warranted because neither site alone has sufficient numbers of both Mexican and Puerto Rican families to conduct this research independently. It is also preferable that interviews and assessments be conducted simultaneously among these two populations to minimize seasonal variations in asthma symptom severity and control and to maximize standardization of survey administration across time and samples. 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). These clinical partner sites provide adequate populations of inner-city, poor Mexican and Puerto Rican children with asthma to recruit the study sample, thus we anticipate no problems recruiting and enrolling 300 families.
