Mindfulness based stress reduction (MBSR(BC)) in breast cancer: evaluating fear of recurrence (FOR) as a mediator of psychological and physical symptoms in a randomized control trial (RCT)
Open accessAbstract
To investigate the mechanism(s) of action of mindfulness based stress reduction (MBSR(BC)) including reductions in fear of recurrence and other potential mediators. Eighty-two post-treatment breast cancer survivors (stages 0-III) were randomly assigned to a 6-week MBSR(BC) program (n = 40) or to usual care group (UC) (n = 42). Psychological and physical variables were assessed as potential mediators at baseline and at 6 weeks. MBSR(BC) compared to UC experienced favorable changes for five potential mediators: (1) change in fear of recurrence problems mediated the effect of MBSR(BC) on 6-week change in perceived stress (z = 2.12, p = 0.03) and state anxiety (z = 2.03, p = 0.04); and (2) change in physical functioning mediated the effect of MBSR(BC) on 6-week change in perceived stress (z = 2.27, p = 0.02) and trait anxiety (z = 1.98, p = 0.05). MBSR(BC) reduces fear of recurrence and improves physical functioning which reduces perceived stress and anxiety. Findings support the beneficial effects of MBSR(BC) and provide insight into the possible cognitive mechanism of action.

In the MBSR study, quality of life was unknown.
“Yet the QoL was unknown”
From Psychosocial Interventions for Improving the Quality of Life in Breast Cancer Survivors: A Literature Review (2019) · cites this paper as [7]
The Discussion’s Limitations section says the effect of MBSR(BC) on long-term quality of life was unknown. But the Methods’ Measures section says quality of life was measured, so the unqualified claim that it was unknown overstates the limitation. No page numbers were available in our copy.

Experimental — accuracy not yet measuredMindfulness therapy effectively overcomes the psychosocial problems experienced by women with breast cancer.
“Mindfulness therapy was effectively overcome the psychosocial problems experienced by women with breast cancer [6] [7] [8] [9].”
From Psychosocial Interventions for Improving the Quality of Life in Breast Cancer Survivors: A Literature Review (2019) · cites this paper as [7]
The Conclusions report that MBSR(BC), compared with usual care, significantly reduced fear of recurrence among breast cancer survivors, with associated reductions in perceived stress and anxiety. This supports benefit for specific psychosocial symptoms, but not the broader claim that mindfulness therapy overcomes psychosocial problems generally. (LLM, conf=0.86)
Experimental — accuracy not yet measuredExperimental groups with MBSR reduced fear of recurrence and improved physical function, which reduced perceived stress and anxiety, significantly compared to the control group given regular care.
“Experimental groups with MBSR have reduced the fear of recurrence and improved physical function that reduces perceived stress and anxiety, significantly compared to the control group given regular care”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
