Table 4 Hayes process mediation model 4: regression and mediation coefficients

n = 69	Change in Y		C1: direct effect of X on Y before mediation		C2: direct effect of X on Y after mediation		A: indirect effect of X on Y mediated via M		B: direct effect of M on Y adjusted for X

Model A
X = Group M = MCCBT1	0.49	.000	0.49	−4.69, 5.68	−1.10	−6.27, 4.05	1.60	0.12, 4.21	0.88	0.16, 1.60
Model B

Models A and B controlled for baseline MCCB and baseline SOFAS. Model C controlled for baseline MCCB and gender
Model A: Y = SOFAS at end of treatment. Model B: Y = SOFAS at 8 months follow up. Model C: Y = number of net positive moves; Results in bold are statistically significant
CI Confidence interval
