Note. AD = Alzheimer’s dementia; MMSE = Mini-Mental State Examination; NPI = Neuropsychiatric Inventory; K-IADL = Katz Index of Activities of Daily Living; GDS = Global Deterioration Scale; CES-D = Center for Epidemiological Studies-Depression; ZBI = Zarit Burden Inventory. β corresponds to standardized beta coefficients. Bold adjusted correspond to models significantly explaining the variance of the dependent variable (i.e., GDS scoring). p < 0.05; p < 0.01; p < 0.001.
