Abstract Objective Patients with breast cancer experience decreased quality of life due to various physical and psychological challenges. Web‐based interventions are accessible, cost‐effective, and convenient for improving their quality of life. This study evaluated whether web‐based interventions improve quality of life and included only randomized controlled trials (RCTs) with clear evidence. Methods PubMed, Embase, Cochrane Library, CINAHL, Web of Science, and PsycINFO were searched for articles published until October 16, 2023. Inclusion criteria were RCTs evaluating the effect of web‐based interventions on quality of life in patients with breast cancer. The risk of bias was assessed with Cochrane's Risk of Bias Tool 2.0. Standardized mean differences were calculated with a random effects model using R version 4.0.3, and subgroup and moderator analyses were performed. Results Since quality of life was measured using two different instruments in two studies, 21 comparisons were analyzed from 19 RCTs. As a result, the findings suggest that web‐based interventions have a small effect size on improving the quality of life for patients with breast cancer (SMD = 0.27, 95% confidence intervals [CIs]: 0.15–0.38, p = 0.03). Heterogeneity was found to be low (I2 = 40%). The quality‐of‐life subdomain results showed a moderate effect size on the physical functioning and a small effect size on the cognitive and emotional functioning of patients with breast cancer but no significant impact on their role or social functioning. Conclusions Web‐based interventions are effective in improving patients' quality of life with breast cancer; they also improve physical, cognitive, and emotional functioning. However, evidence regarding intervention methods remains inconclusive due to the limited number of RCTs, necessitating further research. |
