^aAll items and comparison groups taken from the NHANES III, except injury item and comparison group, which were from the NHIS. The psychiatric sample was based on n = 185 for the items matched to the NHANES and n = 191 for the items matched to the NHIS.

^bMedical conditions included were arthritis rheumatoid, osteoarthritis, asthma, chronic bronchitis, emphysema, diabetes, congestive heart failure, hypertension, stroke, heart failure, and cancer.

^cSignificant differences (p-values = .0024 or less) remained significant after controlling the false discovery rate at 5% (.05).
