Effectiveness of Mindfulness-Based Stress Reduction (MBSR) Interventions on Mindfulness and Stress Symptoms for Cancer Patients: A Quantitative Assessment

A meta-analysis of eight studies found that Mindfulness-Based Stress Reduction (MBSR) interventions for cancer patients and survivors increased mindfulness by an average of 7.93% and reduced stress symptoms by an average of 22.58%. A regression analysis showed a strong negative correlation between mindfulness and stress, suggesting that increases in mindfulness are associated with decreases in stress. The authors conclude that MBSR is effective for enhancing mindfulness and alleviating stress in this population and recommend its use as a complementary therapy in cancer care.

Abstract

The aim of this article is to provide a quantitative assessment of the correlation between heightened mindfulness and stress reduction among cancer patients and survivors who engaged in Mindfulness-Based Stress Reduction (MBSR) interventions. Utilizing data from eight studies, we conducted quantitative analyses to provide the effectiveness scores of MBSR interventions on mindfulness, assessed using the Mindful Attention Awareness Scale (MAAS), and stress symptoms, evaluated through standardized self-reported questionnaires. The effectiveness scores are standardized as percentages relative to baseline (pre-intervention) levels, which allows for the comparison of two variables: mindfulness and perceived stress, on a common scale, facilitating a regression analysis to generate a correlation trendline. The findings reveal that MBSR interventions yielded an average increase in mindfulness levels of 7.93%, with a standard deviation of 4.97%, while concurrently reducing stress or stress-like symptoms by an average of 22.58%, with a standard deviation of 8.77%. Subsequent linear regression analyses were performed on these effectiveness metrics to establish a correlation trendline, demonstrating a robust negative correlation between mindfulness and stress among cancer patients and survivors. In conclusion, MBSR interventions are effective in enhancing mindfulness and alleviating stress or stress-like symptoms in cancer patients and survivors. This finding suggests a causal relationship between mindfulness and stress reduction, endorsing the integration of MBSR as a complementary therapy for cancer management.
