Covariance parameters for the interactive effect of condition and time (study day) predicting daily self-reported mindfulness.

Parameter	Estimate (SE)	Z valuea	P value
Intercept	0.395 (0.134)	2.95	.002
Covariance (I,S)b	−0.006 (0.004)	−1.64	.10
Study day	0.000 (0.000)	2.49	.006
Residual (VCc)	0.526 (0.025)	21.09	<.001

^aThe Z value represents the test value of the z distribution on which statistical significance is determined for this analysis.

^bCovariance between the random parameters for intercept and slope in the multilevel model.

^cVC: variance component (method for structuring the covariance matrix).
