Improving Survey/Cognitive Completions and Home Examination Successes in Wave VI of Add Health

项目摘要 在具有全国代表性的纵向研究中实现高的同意率和应答率是一项紧迫的任务。 科学问题。国家青少年到成人健康纵向研究（Add Health） 包括基于网络的调查和认知功能评估（样本1），基于人的 调查和认知，身体和感觉功能评估（样本2），以及基于血液的家庭 样品1和样品2的检查-现在在现场。在过去的六个月里，我们派出了 我们在一个州进行的基于网络的调查和认知评估，作为样本1的一部分。此外，我们还推出了 2022年6月进行家庭检查，我们正在收集血液以检测AD/ADRD的几种风险标志物， 包括神经变性和炎症。这个试点在两个非常重要的方面做得很好。第一、 我们的实地调查程序运作良好。第二，我们收到的数据，无论是从基于网络的 认知评估调查和用于检测AD/ADRD生物标志物的生物样本， 都是高质量的。同时，从我们的试点实地工作中也已经清楚地看到， 回复率目标和我们的家庭考试回复率目标将非常具有挑战性。这可以是 部分原因是与2019冠状病毒病大流行有关的持续实地工作障碍;两极分化的社会和政治 该国的背景也可能是一个问题，尽管这两个因素都很难确定。但 还有一些关键的研究特定的挑战，其中一些是我们提出这项研究时没有预料到的， 这使得我们的调查响应率目标和我们的家庭考试响应率目标的实现， 难这些因素包括受访者的年龄范围和极其忙碌的生活（40-49岁），时间越长- 我们的调查和认知评估工具的预期长度（特别是对于我们的人 抽样2调查），以及接触我们教育程度较低和种族/少数民族样本的具体挑战 成员鉴于Add Health的巨大科学潜力，特别是考虑到种族/民族和 参与者的社会经济多样性、年龄范围和整体健康状况不佳，增加了对方法的投资 需要增加同意和参与。为了应对上述挑战和机遇， 本补充材料的具体目标是：1）实现最高的基于网络的认知功能调查 第六波抽样1的答复率可能较高，特别是在受教育程度较低和少数民族答复者中， 通过我们将采用的三种新策略。2)实现最高的面对面调查答复率 在第六波抽样2中，特别是在教育程度较低和少数群体的受访者中， 我们将做出两个关键的调整。3)为了实现最高的家庭考试完成率，请添加 第六次健康浪潮，特别是在受教育程度较低和少数群体的受访者中。这将涉及针对 努力实现家庭检查的较高同意率和家庭检查的较高完成率 一旦被调查者同意。

Project Summary Achieving high consent and response rates in nationally-representative longitudinal studies is a pressing scientific issue. Wave VI of the National Longitudinal Study of Adolescent to Adult Health (Add Health) – consisting of a web-based survey and cognitive functioning assessment (Sample 1), an in-person based survey and cognitive, physical, and sensory functioning assessments (Sample 2), and a blood-based home examination for both Sample 1 and Sample 2 – is now in the field. Over the last six months, we have fielded our web-based survey and cognitive assessment in one state as part of Sample 1. In addition, we launched our home exam in June 2022, where we are collecting blood to test for several risk markers for AD/ADRD, including neurodegeneration and inflammation. This pilot has gone quite well in two very important ways. First, our fieldwork processes are working well. Second, the data that we are receiving, both from the web-based survey with cognitive assessment and the biological samples that will be used to test for AD/ADRD biomarkers, are of high quality. At the same time, it is also already clear from our pilot fieldwork that achieving our survey response rate goals and our home exam response rate goal is going to be very challenging. This may be in part due to ongoing fieldwork hurdles related to the Covid-19 pandemic; the polarized social and political context of the country is likely an issue as well, although both of these factors are difficult to ascertain. But there are also key study-specific challenges, some of which were unanticipated when we proposed the study, that make attainment of our survey response rate goals and our home exam response rate goal especially difficult. These include the age range and extremely busy lives of our respondents (ages 40-49), the longer- than-anticipated length of our survey and cognitive assessment instruments (especially for our in-person Sample 2 survey), and the specific challenges of reaching our less-educated and racial/ethnic minority sample members. Given the immense scientific potential of Add Health, particularly given the racial/ethnic and socioeconomic diversity, age range, and overall poor health of participants, enhanced investment in methods to increase consent and participation is needed. In response to the above challenges and opportunities, the Specific Aims of this supplement are: 1) To achieve the highest web-based and cognitive functioning survey response rate possible in Sample 1 of Wave VI, particularly among less-educated and minority respondents, through three fresh strategies we will employ. 2) To achieve the highest in-person-based survey response rate possible in Sample 2 of Wave VI, particularly among less-educated and minority group respondents, through two key adaptations we will be making. 3) To achieve the highest possible home exam completion rate in Add Health Wave VI, particularly among less-educated and minority group respondents. This will involve targeted efforts toward achieving both a higher consent rate for the home exam and a high completion rate for the home exam once respondents are consented.
