The Health and Well-Being of Koreans (HAWK) was a cross-sectional survey of adults ages 18 and older in the United States who are of Korean descent supported by the National Institute on Aging. The goal of HAWK was to implement Web-based respondent driven sampling (Web-RDS) is an extension of RDS, which exploits existing social networks for recruiting research participants, specifically, of small and hard-to-sample groups. In the case of HAWK, the target participants were of granular racial/ethnic minority groups. A total of 772 participated between May 2022 and January 2023. The participants were asked about COVID-19, physical as well as mental health, life satisfaction, health behaviors, healthcare coverage and utilization as well as social relations and networks along with socio-demographic characteristics. The questions mostly come from established surveys, such as the American Community Survey and the California Health Interview Survey. The questionnaires were provided in English and Korean, and participants self-selected the language that they preferred to complete the survey in. The data is expected to provide a broad overview of Korean Americans through the last stage of the Covid-19 pandemic. To protect respondent privacy and data confidentiality, peer recruitment information as well as sensitive information (e.g., citizenship), such variables were excluded from the current file and will be included in a dataset available through ICPSR in a restricted format. Because HAWK uses RDS, which does not follow the conventions of probability sampling, users are advised to exercise caution in making population-level inference with results from the analysis of HAWK data.

Health and Life Study of Koreans, United States, 2016-2018 (ICPSR 37635)

Released/updated on: 2020-09-10

Geographic coverage: United States, Los Angeles County, California, Michigan

Time period: 2016-01-01--2018-12-31

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.

Race/Ethnic Variability in Survey Question Processing and Response (ICPSR 35928)

Released/updated on: 2015-06-03

Geographic coverage: United States

This project collects data from a sample of 1,200 adults representing four distinct cultural groups in the United States: African Americans, Korean Americans, Mexican Americans, and non-Hispanic Whites, to investigate how respondent race/ethnicity and culture influence survey-related behaviors. Sampled adults are further stratified by gender, age, education, and language preference groups. Interviews are audio-recorded and videotaped.
