DESIGN: This will be a longitudinal study of parental illness representations and CAM and controller medication use among a diverse sample of 300 Latino families (primarily Mexican and Puerto Rican) of children with asthma aged 5-12. This age range was selected because children in this age group typically have not assumed daily control for managing their asthma. We will use a structured interview with parents, conduct a short interview with the children, obtain objective measures of lung function from the children, and review children's medical records. Interviews and child assessments will be conducted at five time periods: enrollment, and 3, 6, 9 and 12 months after enrollment, for a total data collection period of 12 months. This assessment schedule will allow us to capture seasonal variations in the children's asthma symptoms as well as conform to the recommendation by NAEPP that children on daily controller medications have follow-up visits every 3 months. Medical record abstractions will take place at the 12-month follow-up.
