Data_Sheet_1_The Correlation Between Quality of Life and Positive Psychological Resources in Cancer Patients: A Meta-Analysis.docx

PurposeThis study aimed to assess the evidence of the association between positive psychological resources and quality of life in patients with cancer.MethodsElectronic searching was performed to retrieve articles from PubMed, Web of Science, Embase, CNKI, and CBM (from inception to 7 April 2022). Summary correlation coefficient (r) values were extracted from each study, and 95% CIs were calculated by the random-effect model. Subgroup and sensitivity analyses were performed to investigate potential heterogeneity.ResultsIn total, sixty-six articles were included in the present study. The pooled r for resilience was 0.71 (95%CI: 0.55, 0.87), hope 0.50 (95%CI: 0.43, 0.56), self-efficacy 0.53 (95%CI: 0.46, 0.61), self-esteem 0.46 (95%CI: 0.28, 0.63), and optimism 0.30 (95%CI: 0.19, 0.40). For subgroup analysis, no significant differences were found between minors and adults.ConclusionThis study indicated that resilience, hope, optimism, self-esteem, and self-efficacy were positively correlated with quality of life in patients with cancers. Therefore, intervention programs should be focused on increasing state-like positive psychological resources to improve the quality of life in patients with cancer.

本项研究旨在评估积极心理资源与癌症患者生活质量之间关联的证据。研究方法包括对PubMed、Web of Science、Embase、CNKI和CBM数据库（自起始至2022年4月7日）的电子检索，以获取相关文章。从每项研究中提取了总结相关系数（r）值，并利用随机效应模型计算了95%置信区间。进行了亚组和敏感性分析，以探究潜在的异质性。结果显示，共纳入本研究的文章共计六十六篇。韧性相关系数的汇总r值为0.71（95%置信区间：0.55，0.87），希望为0.50（95%置信区间：0.43，0.56），自我效能感为0.53（95%置信区间：0.46，0.61），自尊为0.46（95%置信区间：0.28，0.63），乐观为0.30（95%置信区间：0.19，0.40）。在亚组分析中，未成年人与成年人之间未发现显著差异。结论指出，韧性、希望、乐观、自尊和自我效能感与癌症患者的生活质量呈正相关。因此，干预项目应聚焦于提升状态性积极心理资源，以改善癌症患者的生活质量。
