There were 627 degrees of freedom in the denominators for all analyses, except Friends (df = 624) and Spouse (df = 251, because many subjects had not lived with a spouse/partner in the preceding 2 months). There was 1 degree of freedom in the numerator of all analyses except Group (DAT vs. MD vs. nonclinical) and gender x group, which both had 2 degrees of freedom.

^aGroup = Dementia of the Alzheimer’s type vs. Mood disorders (MD) vs. nonclinical.

^bNot significant when corrected for the number of analyses of this variable (16).
