The primary aim of this study is to determine the role of medical care, as well as social and psychological factors in explaining black/white differences in the stage at diagnosis of breast cancer. Black/white differences in stage have been observed in national as well as Connecticut data and contribute to the poorer five-year survival rate among black women. The specific role of medical care factors which influence stage at diagnosis can be appreciated only after thorough exploration of the complex social/psychological factors which either promote or hinder early diagnosis. Previous research suggests that aspects of medical care, like social/psychological factors, may differ for blacks and whites. Specifically, medical care and cancer screening factors are the primary focus of this proposal because of their direct link to stage at diagnosis. Three other categories of factors which may operate indirectly through medical care in affecting stage will also be explored: patient delay in seeking diagnosis once symptoms are detected, knowledge and opinions regarding cancer, and socioeconomic status. This is a retrospective, population-based comparison of black and white breast cancer cases diagnosed in Connecticut between February, 1987 and May, 1989. The study population consists of 148 black women and a 179 white women diagnosed with a first primary breast cancer in 22 Connecticut hospitals. All black breast cancer cases and a random sample of white cases were selected for possible interview. Data were collected by in-person interview and include the following domains of information: 1) general medical care factors; 2) specific factors which describe the steps in the medical care episode which ended with the cancer diagnosis; 3) social-psychological factors; 4) pertinent medical history of cases and reports of cancer in selected blood relatives; 5) health attitudes, beliefs, knowledge, and practices (general and cancer specific); 6) broad sociodemographic and socioeconomic factors. The scope of the data collection instrument will provide a unique opportunity to focus on medical care issues after adjustment for other important contributory factors.

这项研究的主要目的是确定医学的作用 关心，以及解释的社会和心理因素 乳腺癌诊断时阶段的黑色/白色差异。 国家也观察到舞台上的黑色/白人差异 作为康涅狄格州的数据并促进较差的五年生存率 在黑人妇女中。 医疗保健因素的具体作用 只有在彻底之后才能理解诊断的影响阶段 探索复杂的社会/心理因素 促进或阻碍早期诊断。 先前的研究表明 医疗服务的各个方面，例如社会/心理因素，可能有所不同 对于黑人和白人。 具体而言，医疗和癌症筛查 因素是该提案的主要重点，因为他们的直接 链接到诊断时的阶段。 其他三类可能的因素 通过影响阶段间接通过医疗服务也将是 探索：一旦发现症状，患者延迟寻求诊断， 有关癌症和社会经济地位的知识和观点。 这是对黑人和黑色和基于人群的回顾性比较 1987年2月之间在康涅狄格州诊断出的白色乳腺癌病例 1989年5月。研究人群由148名黑人妇女和A组成 179名白人妇女被诊断为22岁的初次乳腺癌 康涅狄格州医院。 所有黑色乳腺癌病例和随机样本 选择白色案件进行可能采访。 收集数据 通过面对面的访谈，包括以下信息领域： 1）一般医疗因素； 2）描述的具体因素 以癌症诊断结束的医疗保健发作中的步骤； 3）社会心理因素； 4）病例相关病史 以及选定血液亲属中癌症的报道； 5）健康态度， 信念，知识和实践（特定于一般和癌症）； 6）广泛 社会人口统计学和社会经济因素。 数据范围 收集工具将为专注于 调整其他重要贡献后的医疗服务问题 因素。
