Also, the mean overall depression score for women with breast cancer in the therapy session was considerably lower than the pre-test score, although optimism was significantly higher than the pre-test score (Pvalue<۰.۰۵).Conclusion: The results of this study support the use of MBSR to minimize symptom burden in women with breast cancer.
