Eligibility criteria: a) The child must be between 5 and 12 years of age, b) have a diagnosis of asthma (described below) as obtained from the child's medical record, c) the family is Latino (English or Spanish speaking) as self-identified by the primary caregiver, d) the child has no other significant pulmonary conditions (e.g., cystic fibrosis), e) the participating parent has primary or at least equal responsibility for the day-to-day management of the child's asthma, and f) no cognitive learning disability that could interfere with the parent's or child's (as determined by parents' report) ability to comprehend the interview questions. All of the recruitment sites have computerized data systems that allow participant identification by diagnosis, age, and ethnicity. If no documentation of a diagnosis of asthma is found in the medical record but asthma is suspected, the potential participant will be offered an appointment for a bronchodilator test for the child. Prior to the test date, the potential participants will be instructed to withhold short-acting β2- agonist medications (e.g., albuterol), caffeine, medicines and drinks containing methylxanthines (e.g., root beer), long-acting bronchodilator medications (e.g., salmeterol, formoterol), and combination agents (e.g., Advair, Symbicort) for 24 hours. Herbal preparations (e.g., kanpo, ding chan tang) and over-the-counter medications (e.g., Primatene™ mist) affecting pulmonary function will also be restricted accordingly.
