This interdisciplinary multi-level study moves the research in asthma health disparities from descriptive studies of individual constructs and contexts to testing an integrated, multi-factorial model among Latino families and children with asthma. The investigators seek to gain a more thorough understanding of the interaction of individual characteristics, cultural and experiential factors, social-environmental context, and healthcare system factors on parents' illness representations, use of CAM and controller medications, and children's asthma health outcomes.
