Regression of psychiatric morbidity on demographic, responsibility, and burden variables

Dependent variable	Independent variables	β	t statistic	p value
Depression symptoms^a	Caregiver age	− 0.00	− 0.02	0.985
	Caregiver education	− 0.36	− 2.23	0.036
	Nursing responsibilities^b	0.65	4.03	0.001
	r = 0.660, F_(3,23) = 5.92, p = 0.004
Anxiety symptoms^a	Caregiver age	− 0.44	− 2.47	0.022
	Caregiver education	0.22	− 1.37	0.185

	Subjective burden	0.03	0.141	0.889
	r = 0.663, F_(4,22) = 4.32, p = 0.01

Note:

Log10 transformed data used in the analyses.

Dichotomized as responsibility for any nursing tasks (yes/no) for multiple regression analyses.
