Acceptability and Feasibility Metrics

	Cronbach’s Alpha	Possible Range	Mean (± SD)
	Cronbach’s Alpha	Possible Range	Yoga	HE	t(p = )
Credibility (CEQ), after first class	0.90	0-1	0.79 (± 0.21)	0.67 (± 0.20)	1.82 (0.08)
Expectancy (CEQ), after first class	0.91	0-1	0.59 (±0.19)	0.48 (± 0.19)	1.57 (0.13)
Program satisfaction, (CSQ-8) Endpoint	0.83	8-32	27.5 (±3.4)	27.4 (±3.9)	0.09 (0.93)

Note. For credibility and expectancy, n=17 and 18 in the yoga arm and HE arm, respectively. For program satisfaction, n=19 in each arm. This includes two people who did not complete the CSQ-8 at M3 assessment but did complete it 3 months later.
