Early detection and preventive measures can reduce the risk of cancer among first degree relatives (FDRs) of cancer patients.Several studies investigated the effect of subjective norm in relation to FDRs' tendency to conduct preventive behaviors. Therefore, the purpose of this study was to systematically evaluate the effect of subjective norms on cancer patients' FDRs as well as their willingness for screening.
PubMed and Scopus were studied to investigate the effect of subjective norms on preventive measures such as breast cancer self-examination, colonoscopy, PSA testing, skin examination, and genetic testing. Odds Ratio (OR), correlation was and confidence intervals were extracted for meta-analysis. After reviewing the studies, only 16 studies met the criteria to be included in this systematic review.
The meta- analysis and OR showed that Physician Recommendation (OR=6.98, 95% CI; 2.55-19.09, P<0.001), Health Care Provider (HCP) (OR=2.79, 95% CI; 1.26-6.16; P=0.011), family and friends (OR=1.82, 95% CI; 1.33-2.50, P <0.001) significantly enhanced the likelihood of referring for screening and preventive measures.
The results of the current study indicated that subjective norms can significantly increase willingness to screening.
早期发现和预防措施可以降低癌症患者一级亲属（FDR）的癌症风险。有几项研究调查了主观规范与 FDR 进行预防行为倾向之间的关系。因此，本研究的目的是系统评估主观规范对癌症患者 FDR 进行筛查的意愿和预防措施的影响。
研究了 PubMed 和 Scopus，以调查主观规范对乳腺癌自检、结肠镜检查、PSA 检测、皮肤检查和基因检测等预防措施的影响。提取了荟萃分析的比值比（OR）、相关性和置信区间。在审查研究后，只有 16 项研究符合纳入本系统评价的标准。
荟萃分析和 OR 表明，医生建议（OR=6.98，95%CI；2.55-19.09，P<0.001）、医疗保健提供者（HCP）（OR=2.79，95%CI；1.26-6.16；P=0.011）、家人和朋友（OR=1.82，95%CI；1.33-2.50，P<0.001）显著提高了进行筛查和预防措施的可能性。
本研究结果表明，主观规范可以显著提高筛查意愿。
