CC1 = Symptom measure for comorbid condition; CC2 = Severity measure for comorbid condition.

Higher scores on severity and impact items indicate greater disease severity or greater disease impact.

Shortness of breath defined in Table 1. Higher scores indicate greater shortness of breath.

Heterotrait correlations r>0.42 (absolute value) failed convergent-discriminant 1-tailed test. Median (r=0.53) correlation from convergent triangle selected for convergent-discriminant comparisons.
