Before developing interventions that target asthma health disparities among this diverse group of Latino families, it is necessary to gain a more thorough understanding of the interaction of individual characteristics, cultural and experiential factors, social-environmental context, and healthcare system factors. The investigators also need to examine how the interaction of these factors impacts parents' illness representations, use of CAM and controller medications, and children's asthma health outcomes. This innovative study moves the research from descriptive studies of individual constructs and contexts to testing an integrated, multi-factorial model. Targeted interventions, aimed at reshaping illness representations, can be developed and implemented to integrate the family's ethnomedical belief system (medical system based on the cultural beliefs of specific ethnic groups) into the biomedical model. The proposed interdisciplinary multi-level study will address gaps in the evidence base and expand the framework for assessing disparities in asthma health outcomes among Latino children. This will be a one-year longitudinal, multi-site study among samples of Mexican and Puerto Rican parents and children aged 5-12 who have asthma. This age range was selected because children in this age group typically have not assumed daily control for managing their asthma.
