An online mindfulness-based stress reduction (MBSR) program reduced anxiety and depression in breast cancer survivors with elevated anxiety. In a randomized trial, 68 survivors were assigned to an 8-week online MBSR course or a waitlist control. MBSR participants showed significantly greater reductions in anxiety (average 4.13 points lower on the GAD-7) and depression (average 6.03 points lower on the PHQ-9) compared to controls, with benefits lasting through 8 months of follow-up. The proportion of MBSR participants with clinically significant anxiety dropped from 96% before the program to 38% at 8 months, while control group rates stayed around 88%. No significant differences were found for fatigue, insomnia, cancer worry, or vasomotor symptoms.
