Changes on secondary outcomes, associations with communitas.

	Baseline (N = 819)		Key endpoint (N = 399)					Change scores vs. communitas
	M	SD	M	SD	t	p	d	r	p
QIDS	6.98	4.77	4.20	3.33	−11.015	<0.0001	−0.60	−0.11	0.04
STAI	13.53	4.27	11.13	3.65	−11.745	<0.0001	−0.53	−0.16	<0.01
IPTS	5.57	0.74	5.69	0.68	5.043	<0.0001	0.19	0.19	<0.001

Means (M) and standard deviation (SD) are reported for each outcome at baseline (2 weeks before) and key endpoint (4 weeks after) a psychedelic retreat or ceremony. Significance and Cohen's d effect sizes are reported for two-sided pairwise t-tests, as well correlation coefficients with Communitas experienced during the psychedelic sessions. QIDS: Quick Inventory of Depressive Symptomatology; STAI: Trait version of the State-Trait Anxiety Inventory; IPTS: warm tolerance subscale of the Interpersonal Tolerance Scale.
