Acceptance and commitment training focused on repetitive negative thinking for clinical psychology trainees: A randomized controlled trial

Controlled trial in 85 psychology students (6 RNT-focused group sessions vs WL). Training reduced emotional symptoms (d≈0.75), depression, values-obstructing behaviors, and RNT (greater effects in those with elevated symptoms). Practice-focused RNT reduction mediated effects; suggests an effective brief program for trainees.
