Comparison of reaction time and percentage interference between pre- and post-MBCT on grief bereavement.

Source	Congruent		Incongruent		% Interference
	Mean	SE	Mean	SE	Mean	SE
Pre-MBCT	549.8	11.4	623.8	13.9	13.1	1.4
Post-MBCT	564.5	10.6	608.0	11.7	8.7	1.8
Significance	Interaction:				Mann–Whitney†
	F(1,18) = 6.73, p = 0.018∗				z = -2.33, p = 0.002∗∗

^†Mann–Whitney test was used instead of paired t-test because of the normality violation. ^∗p < 0.05; ^∗∗p < 0.01.
