背景：乳房X光检查对于早期发现乳腺癌和提高存活率是必不可少的。妇女，特别是那些社会经济地位较低的妇女，面临阻碍她们坚持筛查的障碍。尽管许多研究试图确定这些障碍，但还需要更多的研究来解决实践中的这些障碍。这项研究的目的是利用经验证据将乳房X光检查筛查障碍划分为功能簇，这可能会指导有效的乳房X光检查宣传信息的发展。方法：从管理型医疗机构随机选择173名低收入白人和黑人女性，对21个潜在的乳房X光检查障碍中的每一个进行评级，范围从“强烈同意”到“强烈不同意”。结果：共划分出5个类群，相似度指数较高(0.881)。每个集群的命名是为了反映其内部障碍的共同主题：感知到的医疗保健价值缺乏、缺乏信息、不信任/怀疑、医疗延误行为和焦虑/无法控制。在每个分类中确定了一个主要障碍，并报告了双变量相关系数。结论：聚类分析产生了5个不同的乳房X光摄影筛查障碍亚组。版权所有(C)2012年，由雅各布斯妇女健康研究所所有。由爱思唯尔公司出版。
Background: Mammography screening is essential for early detection of breast cancer and increased survival rates. Women, particularly those of low socioeconomic status, face barriers that impede their screening adherence. Although many studies have sought to identify these barriers, more research is needed on to address these obstacles in practice. The objective of this study is to divide mammography screening barriers into functional clusters using empirical evidence, which may guide the development of effective mammography screening promotion messages.Methods: A sample of 173 low-income White and Black women randomly selected from a managed care organization rated each of 21 potential mammography barriers on a scale ranging from "strongly agree" to "strongly disagree." A maximum clustering similarity method was used to identify relevant clusters of screening barriers.Results: Five clusters were derived, with a high similarity index (0.881). Each cluster was named to reflect the shared theme of the barriers within it: Perceived Lack of Value in Health Care, Lack of Information, Mistrust/Skepticism, Medical Delay Behavior, and Anxiety/No Control. A dominant barrier within each cluster was identified, and bivariate correlation coefficients were reported.Conclusion: Cluster analysis yielded five distinct subgroups of mammography screening barriers.
