^aMMSE, Mini-mental State Exam; Blessed, Blessed Dementia Rating Scale; CSDD, Cornell Scale for Depression in Dementia for patients; CESD, Center for Epidemiological Studies Depression Scale for caregivers; CG Gender, caregivers' gender coded so that a positive coefficient indicates that women caregivers were more likely to report the behavior; CG age, informant age similar or younger than the patient, coded so that a negative coefficient indicates that younger caregivers were more likely to report the behavior; Patient gender, patient gender coded so that a positive coefficient indicates that women were more likely to display the behavior.

^bTests associated with these factors reflect difference from base category which was non-Hispanic whites.
