Associations of Summary Physical Functioning Factor for Persons with Dementia and Aspects of Caregiving (N=1,211)

Parameter	Caregiver burden			Depressive symptoms of the caregiver
	Estimate	Standard Error	95% Confidence Interval	Estimate	Standard Error	95% Confidence Interval
Residual baseline covariance	3.37*	1.89	(1.47, 5.26)	2.74*	2.23	(0.51, 4.96)
Regression of slope on PWD physical functioning	−0.23*	0.04	(−0.29, −0.14)	−0.08	0.04	(−0.17, 0.00)
Intercept for PWD physical functioning	43.52	0.34		43.49	0.35
Intercept for model outcome	51.34	0.29		51.09	0.30
Slope for model outcome	4.82	2.17		−2.32	2.76

^*p<0.05, PWD = persons with dementia

Note: The first row 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 presents regressions of rate of change for each negative aspect of caregiving on the baseline physical functioning factor of the persons with dementia. Subsequent rows provide model-estimated mean levels and rates of change in each exposure and outcome. 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.
