Health Literacy and Self-Efficacy Among Low-Income Men with Prostate Cancer

描述（由申请人提供）：自我效能感和健康素养都影响个人如何能够获得和理解与癌症有关的症状管理信息，以及如何自信地执行管理症状所需的技能。有效管理前列腺癌治疗相关症状是维持良好生活质量的必要条件。然而，许多低收入前列腺癌患者的自我认知和自我效能都很低，但我们不知道这两个特征是如何共同影响这些人的生活质量的。在低收入和文化多样化的人口中，卫生知识普及对可能影响个人控制其疾病、从而有效控制症状和维持生活质量的能力的因素的影响知之甚少。其中一个因素，自我效能感或对自己与医生互动能力的信心，或自我效能感与健康素养之间的关系，在很大程度上尚未与健康素养相关。然而，低自我效能也被证明不利于获取和理解关键的健康信息。因此，本研究旨在探讨健康素养与医患互动自我效能、前列腺癌特异性症状功能和烦恼、健康相关生活质量（HRQOL）之间的关系。确定重要的关联将有助于理解卫生知识普及在获取和理解有效自我管理慢性、危及生命的疾病所必需的信息方面所起的作用，并为制定针对极端脆弱个体需求的具体干预措施奠定基础。本研究的具体目的是：1。使用标准化仪器测量健康素养、与医生互动的自我效能、疾病特异性和一般健康相关生活质量（HRQOL）。检查健康素养水平和自我效能与医生互动、HRQOL、疾病特异性QOL和社会人口因素之间的关系。为了实现这些目标，横断面描述性设计将采用二级和初级数据。我们将随机抽取100名在公共资助项目中接受前列腺癌治疗并参与HRQOL研究的低收入男性，并使用英语或西班牙语进行功能健康素养测试。统计分析将分为两个阶段。第一阶段将检验社会人口学因素与健康素养评分之间的成对关联，以及社会人口学措施和健康素养评分与疗效和生活质量结果之间的成对关联[PEPPI评分、一般HRQOL （SF-12）和疾病特异性HRQOL (UCLA PCI)]。PAR-04-117理解和促进健康素养（RO3）说明：项目总结和相关性。在低收入和文化多样化的人口中，卫生知识普及对可能影响个人控制其疾病、从而有效控制症状和维持生活质量的能力的因素的影响知之甚少。其中一个因素，自我效能感，对自己与医生互动能力的信心，或者自我效能感和健康素养之间的关系，在很大程度上尚未与健康素养相关。然而，低自我效能也被证明不利于获取和理解关键的健康信息。因此，本研究旨在探讨健康素养与医患互动自我效能、前列腺癌特异性症状功能和烦恼、健康相关生活质量（HRQOL）之间的关系。确定重要的关联将有助于理解卫生知识普及在获取和理解有效自我管理慢性、危及生命的疾病所必需的信息方面所起的作用，并为制定针对极端脆弱个体需求的具体干预措施奠定基础。

DESCRIPTION (provided by applicant): Self-efficacy and health literacy both influence how an individual is able to obtain and understand symptom management information related to cancer, and to feel confident in performing the skills needed to manage symptoms. Managing prostate cancer treatment-related symptoms effectively is necessary to maintaining good quality of life. However, many low-income men with prostate cancer have low self-literacy and low self-efficacy, but we do not know how these 2 characteristics may work together to influence quality of life for these men. Little is known about the effects of health literacy in low-income and culturally diverse populations on the factors that might influence an individual's ability to take charge of their illness such that symptoms can be effectively managed and quality of life maintained. One of these factors, self-efficacy or confidence in one's ability to interact with physicians, or how self-efficacy and health literacy, may be associated are largely unexplored in relation to health literacy. Yet, low self-efficacy has been shown to be detrimental to obtaining and understanding critical health information, also. Therefore, this study seeks to examine relationships between health literacy and self-efficacy for patient-physician interaction, prostate cancer-specific symptom function and bother, and health-related quality of life (HRQOL). Identification of significant associations will help in understanding the role that health literacy plays in obtaining and understanding information necessary for effective self-management of chronic, life-threatening illness and to lay the groundwork for the development of interventions specific to the needs of extremely vulnerable individuals. The specific aims of this study are to: 1. Measure health literacy, self-efficacy for interacting with physicians, and disease specific and general health related quality of life (HRQOL) using standardized instruments and 2. Examine associations between health literacy level and self-efficacy for interacting with physicians, HRQOL, disease-specific QOL, and sociodemographic factors. To accomplish these goals a cross-sectional descriptive design will be used employing secondary and primary data. We will randomly sample 100 low-income men treated for prostate cancer in a public-funded program and participating in a HRQOL study and administer the Test of Functional Health Literacy in English of Spanish. The statistical analysis will consist of two stages. The first stage will be to examine pairwise associations between sociodemographic factors and health literacy scores as well as associations between sociodemographic measures and health literacy scores with efficacy and QOL outcomes [PEPPI scores, general HRQOL (SF-12), and disease-specific HRQOL (UCLA PCI)].
