  1. MBSR = Mindfulness-based stress reduction. BEAT Cancer trial = Better Exercise Adherence after Treatment for Cancer trial. FSI = Fatigue Symptom Inventory. SF-36 Vitality = Short Form-36 Vitality subscale. Change = baseline score—post-intervention score. Between-group effect size = (Intervention group change—control group change)/ pooled baseline SD. Between-group SRM = (Intervention group change—control group change)/SD of pooled change score
