Family caregiving of older adults is more common in Korea than in the United States. Son et al. (A-3)

studied 100 caregivers of older adults with dementia in Seoul, South Korea. The dependent variable was caregiver burden as measured by the Korean Burden Inventory (KBI). Scores ranged from 28 to 140, with higher scores indicating higher burden. Explanatory variables were indexes that measured the following:

ADL: total activities of daily living (low scores indicate that the elderly perform activities independently).

MEM: memory and behavioral problems (higher scores indicate more problems).

COG: cognitive impairment (lower scores indicate a greater degree of cognitive impairment).

The reported data are as follows:

KBI (Y ) ADL (X1) MEM (X2) COG (X3) KBI (Y ) ADL (X1) MEM (X2) COG (X3)
