Health and Life Study of Koreans, United States, 2016-2018

The Health and Life Study of Koreans (HLSK) was conducted as a part of the study, "Empirical Assessment of Respondent Driven Sampling from Total Survey Error Perspectives" supported by the National Science Foundation. The larger study aimed to examine the operational and inferential properties of respondent driven sampling (RDS). HLSK applied RDS using a web survey, to examine the health of foreign-born Korean-American adults living in Los Angeles County or the State of Michigan. It should be noted that the literature on analysis of RDS data is not fully established, and there is less than clear empirical evidence illustrating the fit of using RDS for population-level inferences. Hence, data users are advised to exercise extreme caution in making population-level inferences.
This study uses existing questions from established surveys such as the American Community Survey (ACS), Kessler survey of psychological distress, and the California Health Interview Survey (CHIS). The Main Survey covers topics like socio-demographics, physical and mental health, healthcare utilization, religiosity, political engagement, psychosocial traits, and racial/ethnic identity. The Follow-up Survey and Restricted Data focuses on RDS sampling questions and allows users to examine the relationships between recruiters and their recruits. Additionally, the Follow-up Survey and Restricted Data includes variables that contain sensitive information such as multi-racial identity, citizenship status, and physical health characteristics.

韩裔健康与生活研究（Health and Life Study of Koreans, HLSK）作为"基于总调查误差视角的受访者驱动抽样实证评估"项目的子研究开展，该项目由美国国家科学基金会资助。该母体研究旨在探究受访者驱动抽样（Respondent Driven Sampling, RDS）的操作特性与推断特性。HLSK采用网络调查方式实施RDS，以调研居住于洛杉矶县或密歇根州的海外出生韩裔美国成年人的健康状况。需要说明的是，当前针对RDS数据分析的研究体系尚未完全成熟，尚无明确的实证证据表明RDS适用于总体层面的统计推断。因此，建议数据使用者在进行总体层面推断时保持极度谨慎。
本研究采用了成熟调查问卷中的既有问题，包括美国社区调查（American Community Survey, ACS）、凯斯勒心理痛苦量表调查以及加州健康访谈调查（California Health Interview Survey, CHIS）。主调查问卷涵盖社会人口统计学特征、身心健康状况、医疗服务利用、宗教信仰情况、政治参与度、社会心理特质以及种族/族裔身份认同等议题。追踪调查问卷与受限数据集聚焦于RDS抽样相关问题，可供使用者分析招募者与被招募者之间的关联。此外，追踪调查问卷与受限数据集包含多族裔身份认同、公民身份以及身体健康特征等敏感信息变量。
