Comparison of responses according to time on the job and primary species tended

			Tukey multiple–comparisons test
Statement	Variable	ANOVA	Groups compared	Mean difference	SE of difference	P
I feel frustrated when I cannot help an animal because the needed treatment is not allowed under the protocol, or because disease or injury is part of the model.	Time on job	F2, 303 = 5.618 P < 0.005	0–5 vs 6–10	3.494	4.807	ns
			0–5 vs >10	12.04	4.027	< 0.05
			6–10 vs >10	8.542	3.838	ns
The animals I work with are capable of a full range of emotions, from depression and fear to joy and anticipation.	Time on job	F2, 305 = 3.502 P < 0.05	0–5 vs 6–10	4.386	4.137	ns
			0–5 vs >10	8.808	3.466	< 0.05
			6–10 vs >10	4.422	3.280	ns
	Species	F2, 305 = 3.494 P < 0 0.05	Mixed vs large	–4.895	3.710	ns
			Mixed vs small	3.193	3.352	ns
			Large vs small	8.088	3.061	< 0.05
It is up to the IACUC to decide if the value of the research project justifies animal use. Once a protocol is approved, I will support it.	Species	F2, 303 = 5.241 P < 0.05	Mixed vs large	–1.454	3.645	ns
			Mixed vs small	–9.059	3.288	< 0.05
			Large vs small	–7.605	3.015	< 0.05
I maintain some professional distance between myself and the animals I work with. I think it is best not to become too emotionally involved.	Species	F2,304 = 5.949 P < 0.005	Mixed vs large	–11.50	4.845	< 0.05
			Mixed vs small	–15.02	4.367	< 0.005

ns, not significant

Groups regarding time on the job: 0–5 y, 6–10 y, and >10 y. Groups regarding primary species: large, majority large animals; mixed, equal large and small animals; and small, majority small animals. Groups in boldface agreed more strongly in the listed comparison. Only significant ANOVA results and their post hoc comparisons are reported. Degrees of freedom are reported as a subscript to the F statistic; α = 0.05.
