Note. All predictors found to be statistically significant (p < .05) in bivariate analyses were included in full models; OR = odds ratio; 95%CI = 95% confidence interval; IADL = Instrumental Activities of Daily Living; BADL = Basic Activities of Daily Living; SP = Study Partner.
a
1 to 5 with higher rankings being better.
b
IADL = Informant rating of participant’s functioning on five IADLs, where higher scores reflect greater impairment.
c
BADL = Informant rating of participant ‘s functioning on six BADLs, where higher scores reflect greater impairment.
d
Two missing observations.
e
6.5% missing data (n=44).
f
9.0% missing data (n=66).
