Latent difference score model with decentering as the mediator and depressive symptoms as outcome. Path coefficients (unstandardized) are estimated separately for ACT (italics) and CBT (boldfaced) as this model resulted in a superior fit to a model with equality constraints on the difference score to outcome path coefficients. EQ-D = EQ-D scores, QIDS = QIDS-SR scores, pre = pre-treatment, s = session number during treatment, post = post-treatment, ∆ = latent difference score. *** p < .001, **p < .01, *p <.05, ns = non-significant
