a
Poor was coded as 1=yes if enrolled in Medicaid/SCHIP and 0=no.
b
Clinic setting was coded 0=private practice and 1=hospital-based ambulatory clinic.
c
Asthma duration was computed as age at interview (months)-age at diagnosis (months).
d
Items are scored on a 5-point Likert-type scale; responses range from 1 (strongly agree) to 5 (strongly disagree). Higher scores represent beliefs aligned with the professional model. The total score was calculated as the mean of the items.
e
Health care visits were abstracted from the medical record and obtained from parent report.
