Mediators’ Prediction of Symptom Change after Session 10 (Hostile Resistance Not Included as a Covariate).

Mediator x Time Term	n	β	SE	t (df)	p	r	CI 95%
Adherence	54	0.10	0.26	0.37 (87)	.71	.05	−.22, .31

Off-Protocol-Squared	56	1.67	3.03	0.55 (91)	.58	.07	−.19, .33
Working Alliance-Client, Residualized	36	0.10	0.31	0.32 (62)	.75	.05	−.28, .38
Working Alliance-Therapist, Residualized	52	0.22	0.26	0.85 (88)	.40	.11	−.16, .38

Note: Results were generated using hierarchical linear modeling. All putative mediators were measured at Session 10 with the exception of the two working alliance variables, which are residualized change scores (i.e., residuals of regressing Session 10 alliance on the average of alliance scores from Sessions 2 and 5).
