BDI-II = Beck Depression Inventory-II; DAS-18B = Dysfunctional Attitudes Scale, Version 18-B; HDRS = Hamilton Depression Rating Scale; RRS = Ruminative Response Scale; MCQ-PB = Metacognition Questionnaire-Positive Beliefs subscale. **p < 0.01; *p < 0.05. Treatment group coded as MCT-Silver = 1 and active control = 0. Higher scores on the mediators and outcomes indicate greater reductions. Bold indicates that the 95% confidence interval does not encompass zero.
