Daily Experiences and Well-being in Late Life, Austin, Texas, 2016-2017

The Daily Experiences and Well-Being Study (DEWS) was conducted in 2017 by the University of Michigan Survey Research Center. Adults aged 65 and older were recruited from the greater Austin Texas Metropolitan Statistical Area. To be eligible for the study, respondents had to be aged 65 or older, community dwelling, cognitively capable of completing the study, and not working full time. Surveys and interviews were conducted in Spanish or English. After an initial phone screening, a local interviewer contacted the respondent to conduct an in-person interview that lasted approximately 1.5 to 2 hours. They then engaged in a 5-6 day intensive data collection, involving ambulatory assessments. The study provided handheld Android devices (i.e. smart phones) for the additional data collection, as well as training in the use of these devices to complete surveys. The devices gathered self-reports of social interactions, activities and mood every 3 hours via ecological momentary assessments, EMA), recorded conversations 30 seconds out of every 7 minutes, (via electronically activated recordings, EAR), and physical activity every minute measured via actigraphs (Actical). At the end of the intensive data collection, the interviewer returned to the respondent's house to pick up the devices as well as a self-administered Leave-Behind Questionnaire (LBQ). A total of 333 respondents completed the baseline interview, 326 (97.9%) of whom completed device collection. This collection includes an in-person interview (baseline/global), additional device collection (EMA, EAR, Actical), and Leave Behind Questionnaire. These data provide information on how social partners contribute to emotional, physical and cognitive experiences and to daily and global well-being. Demographic information includes age, race, ethnicity, gender, marital status, living arrangement, and education level.

每日体验与幸福感研究（Daily Experiences and Well-Being Study, DEWS）由密歇根大学调查研究中心于2017年开展。研究从德克萨斯州大奥斯汀都会统计区招募65岁及以上成年人作为受试者。本研究的入选标准为：年龄年满65周岁、社区居住、具备完成研究所需的认知能力且未从事全职工作。

调查与访谈采用西班牙语或英语进行。流程首先为电话初筛，随后由本地访员联系受试者开展时长约1.5至2小时的当面访谈。此后受试者需参与为期5至6天的密集数据采集工作，涵盖流动评估。

研究为额外数据采集提供了手持安卓设备（即智能手机），并配套设备使用培训以协助受试者完成问卷填报。该设备通过生态瞬时评估（ecological momentary assessments, EMA）每3小时采集一次社交互动、活动与情绪的自我报告；通过电子激活录音（electronically activated recordings, EAR）每7分钟录制30秒的对话内容；同时通过活动记录仪（Actical）每分钟采集一次身体活动数据。

密集数据采集结束后，访员将返回受试者家中回收设备及自评式留置问卷（Leave-Behind Questionnaire, LBQ）。最终共有333名受试者完成基线访谈，其中326人（占比97.9%）完成了设备数据采集流程。

本数据集包含当面基线/整体访谈、设备采集数据（EMA、EAR、Actical）及留置问卷相关内容。这些数据可用于解析社交伙伴对个体情绪、生理与认知体验，以及日常与整体幸福感的影响。人口统计学信息涵盖年龄、种族、族裔、性别、婚姻状况、居住安排及受教育水平。
