Associations of Summary Physical Functioning Factor of Persons with Dementia and Negative Caregiving Aspects by Caregiver Race (N=1,211)

Parameter	Caregiver burden			Depressive symptoms of the caregiver
	Estimate	Standard Error	95% Confidence Interval	Estimate	Standard Error	95% Confidence Interval
Non-white Caregivers (n=481)
Residual baseline covariance	1.84	1.89	(−0.04, 3.73)	4.21*	3.38	(0.83, 7.59)
Regression of slope on PWD physical   functioning	−0.14*	0.07	(−0.28, −0.01)	−0.04	0.10	(−0.22, 0.18)
White Caregivers (n=730)
Residual baseline covariance	2.63	5.45	(−2.82, 8.08)	−0.09	0.85	(−0.94, 0.75)
Regression of slope on PWD physical   functioning	−0.27*	0.07	(−0.40, −0.14)	−0.12*	0.06	(−0.24, −0.02)

^*p<0.05, PWD = persons with dementia

Note: The first row under each subgroup presents associations of the intercept of the summary physical functioning factor of persons with dementia with the intercepts for negative caregiving aspects. The second row under each subgroup presents regressions of rate of change for each negative aspect of caregiving on the baseline physical functioning factor of persons with dementia. For factor scores representing physical functioning of persons with dementia, caregiver burden, and caregiver depressive symptoms, higher scores indicate greater impairment, more burden, and more depressive symptoms, respectively.
