Enhancing quality of life in Iranian women with breast cancer: the efficacy of psychological interventions. A meta-analysis

This meta-analysis assessed the impact of psychological interventions on the quality of life of breast cancer patients in Iran, reviewing sources from 2006 to 2021, including theses, journals, and international research by Iranian authors. The study analyzed 40 clinical trials with effect sizes, sourced from databases like Magiran, Civilica, Normgs, Scientific-Research Journals, Irandoc, PubMed, Scopus, and PsycINFO, involving 1946 participants. The overall effect size was 0.45, with a significant level of p<0.001, indicating a considerable impact on patients’ quality of life. The highest effect sizes were d=1.91 and Fisher’s z (Zr)=0.84, while the lowest were d=0.28 and Zr=0.14. According to Cohen’s interpretation, these interventions have a moderate effect size, suggesting they can effectively improve the quality of life for breast cancer patients. The study highlights the potential of psychological interventions as a non-pharmacological strategy for enhancing patient well-being, emphasizing their importance in breast cancer care in Iran. This research supports the adoption of psychological interventions to improve the quality of life among individuals diagnosed with breast cancer.
