STATISTICAL ANALYSIS Aim #1: Are there differences in illness representations between Mexican and Puerto Rican parents due to social and contextual factors (i.e., acculturation, education, parental age, poverty, child's illness duration, household members with asthma, and parent-healthcare provider relationship)? Ethnicity (0=Mexican 1=Puerto Rican) and healthcare setting (1=school-based 2=Breathmobile 3=hospital-based) will be entered as classification factors in the regression model with the above covariates to examine differences in the total AIRS© score as well as the individual subscale scores. The interaction of acculturation and ethnic group will be included to assess the potential mediation effect of acculturation on IR.
