Stage 2—validation of the abbreviated adapted Zarit Burden Interview (ZBI) across samples of veterinary clients recruited through a small animal general veterinary hospital and a large academic hospital with specialty services who reported ownership of a sick dog or cat and provided responses to an online research protocol including the ZBI adapted for use with pets, the Perceived Stress Scale (PSS), and the Quality of Life Enjoyment and Satisfaction Questionnaire‐Short Form (Q‐LES‐Q‐SF)

Validation sample	N	Full ZBI			Abbreviated ZBI			r with abbreviated ZBI
		M (SD)	Range	Cronbach's α	M (SD)	Range	Cronbach's α	Full ZBI	PSS	Q‐LES‐Q‐SF
General veterinary	118	18.84 (9.85)	0‐56	.86	7.57 (4.16)	0‐22	.73	0.93	0.40	−0.34
Specialty internal med	144	17.14 (9.56)	0‐48	.86	7.10 (4.20)	0‐20	.75	0.88	0.57	−0.42
Oncology	49	16.67 (10.43)	2‐46	.88	5.92 (4.11)	0‐14	.71	0.90	0.75	−0.56
Other specialty	148	15.45 (9.78)	0‐50	.86	6.17 (4.06)	0‐19	.71	0.91	0.57	−0.32

Note: “Other Specialty” includes orthopedics, neurology, cardiology, behavior, dermatology, and ophthalmology. Correlations between the abbreviated adapted ZBI and PSS/Q‐LES‐Q‐SF were all significant, P < .001.
