IMPACT OF DATA COLLECTION MODE ON LOW-LITERACY SUBJECTS

据估计，47%的美国成年人口(9000万 (成年人)识字能力低。在美国进行的研究 各国和发展中国家都发现，拥有 识字能力差的人往往比成年人的健康状况更差。 具有更高的识字水平。这种关联在其他情况下仍然存在 在分析中控制了社会经济因素。为了进一步 检查这种关系以及为什么它可能存在，调查人员需要 请确保所使用的数据收集模式为 适用于识字能力较低的受访者。很少有研究 已经进行了研究以评估数据收集的影响 模式与低识字率的受试者。建议的随机化 研究将考察三种数据收集模式对以下方面的影响 数据质量与这一人群的样本进行比较。实现以下三种模式 被研究的是面试者管理(IA)，纸和铅笔自我 管理(PPSA)和音频计算机辅助的自我访谈 (ACASI)。健康中常用的两种测量仪器 这项研究将使用以下研究：简明健康调查 (SF-36)和流行病学研究中心的抑郁量表 (CES-D)。因为较差的识字率在少数民族中更为普遍 和低收入人群，主题将是低收入非洲人- 美国女性。要符合资格，受试者的年龄必须在 --35岁及以下年级同等阅读能力 六年级水平，由成人识字快速评估来衡量 医学(领域)。研究的具体目的是：1) 检查数据收集模式对数据质量的影响， 以报告水平、缺失率、规模为特征 内部一致性；和反应偏差；以及2)检查 心理障碍造成的认知负担之间的关系 测量工具和受试者的认知能力。

It is estimated that 47% of the U.S. adult population (90 million adults) have low literacy skills. Studies conducted in the United States and in developing countries have found that populations with poor literacy skills tend to have poorer health as compared to adults with higher levels of literacy. This association remains when other socioeconomic factors are controlled in analysis. In order to further examine this relationship and why it may exist, investigators need to be assured that the modes of data collection being used are appropriate for respondents with low literacy skills. Few research studies have been conducted to assess the impact of data collection mode with subjects who are low literate. The proposed randomized study will examine the impact of three modes of data collection on data quality with a sample from this population. The three modes to be studied are interviewer administered (IA), paper-and-pencil self- administered (PPSA), and audio computer-assisted self-interviews (ACASI). Two measurement instruments frequently used in health research will be used in this study: the Short-Form Health Survey (SF-36) and the Center for Epidemiologic Studies Depression Scale (CES-D). Because poor literacy is more prevalent among minority and low income populations, subjects will be low income African- American women. To be eligible, subjects must be between the ages of 35-64 years and grade equivalent reading abilities at or below the 6th grade level, as measured by the Rapid Estimate of Adult Literacy in Medicine (REALM). The specific aims of the study are to 1) examine the effects of mode of data collection on data quality, characterized by level of reporting, rates of missing values, scale internal consistency; and response bias; and 2) to examine the relationship between the cognitive burden imposed by the measurement instruments and subjects cognitive abilities.
