	Variables	Fcha	r2cha	β	Partial r	t-value	Significant
Step 1 enter		2.20	0.12

Predictors are age, gender, change scores from pre-treatment to 1-year follow-up ΔRRS, ΔPSWQ and ΔMCQ-30 using forward variable selection. Δ, changes from pre-treatment to 1-year follow-up scores; BDI, Beck Depression Inventory; MCQ-30, Metacognitions Questionnaire-30; PSWQ, Penn State Worry Questionnaire; RRS, Ruminative Response Scale.
