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会影响个人如何获得和理解与癌症有关的症状管理信息，并对执行管理症状所需的技能感到自信。有效地管理前列腺癌治疗相关症状对于保持良好的生活质量是必要的。然而，许多患有前列腺癌的低收入男性的自我识别力和自我效能感都很低，但我们不知道这两个特征如何共同作用来影响这些男性的生活质量。关于低收入和文化多样性人群的健康素养对可能影响个人控制其疾病的能力从而有效管理症状和维持生活质量的因素的影响，人们知之甚少。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，或者自我效能感与健康素养可能如何关联，在健康素养方面基本上没有被探索。然而，低自我效能感也被证明不利于获得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、前列腺癌特有症状功能与困扰、健康相关生活质量(HRQOL)之间的关系。确定重大关联将有助于理解卫生知识在获取和了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发挥的作用，并为制定针对极端脆弱个人需要的干预措施奠定基础。本研究的具体目的是：1.使用标准化工具测量健康素养、与医生交往的自我效能感以及特定疾病和一般健康相关生活质量(HRQOL)；2.检验健康素养水平与与医生互动的自我效能感、HRQOL、疾病特定生活质量和社会人口统计因素之间的关系。为了实现这些目标，将使用横断面描述性设计，使用二手和一手数据。我们将在一个公共资助的项目中随机抽取100名接受前列腺癌治疗的低收入男性，并参与一项HRQOL研究，并用西班牙语进行英语功能性健康素养测试。统计分析将分为两个阶段。第一阶段将检查社会人口因素和健康素养得分之间的成对关系，以及社会人口统计测量和健康素养得分与疗效和生活质量结果[Peppi得分、一般HRQOL(SF-12)和疾病特定HRQOL(UCLA PCI)]之间的关系。PAR-04-117了解和促进健康素养(R03)说明：项目摘要和相关性。关于低收入和文化多样性人群的健康素养对可能影响个人控制其疾病的能力从而有效管理症状和维持生活质量的因素的影响，人们知之甚少。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可能如何关联，在健康素养方面基本上没有被探索。然而，低自我效能感也被证明不利于获得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、前列腺癌特有症状功能与困扰、健康相关生活质量(HRQOL)之间的关系。确定重大关联将有助于理解卫生知识在获取和了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发挥的作用，并为制定针对极端脆弱个人需要的干预措施奠定基础。

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)].
