  • * NS = not statistically significant.

  • Mean of 5 symptoms, based on NIH criteria, 0 = mild, 2 = severe.

  • Mean of 9 ratings of communication, involvement, access, and overall care, 1 = excellent, 5 = poor.

  • § Percentage correct out of 11 items.

  • Mean agreement with 6 items emphasizing perceived controllability of asthma. (1 = strongly agree, 4 = strongly disagree).

  • Mean reported frequency of 12 desirable behaviors; 1 = almost always, 4 = hardly ever.
