Summary

The University of California, Irvine COVID-19 Study is a longitudinal study of over 6,500 people from the NORC AmeriSpeak panel, a probability-based nationally representative sample of U.S. households on whom baseline mental and physical health data were collected prior to the start of the COVID-19 threat in the U.S. The study addresses the emotional (fear, worry, distress), cognitive (perceived risk), and behavioral (media use, health protective behaviors) responses to the COVID-19 outbreak and how they shape health outcomes over time. Researchers also examine how direct and indirect exposure through widespread media coverage of the COVID-19 outbreak are associated with acute stress responses, the media's success (or failure) in affording people the information needed to understand the threat, and how cognitive and affective processes shape risk assessments, behavioral responses, and mental health outcomes. Researchers have examined national trends over time in respondents' risk perceptions, fear, media use, health protective behaviors, and distress surrounding the outbreak.

Study Purpose

The purpose of this study is to assess risk perceptions, media use, acute stress, social norms, self- and response-efficacy, and protective behaviors at the start of an ambiguous and deadly domestic threat on a large representative sample with existing pre-threat mental and physical health data.

Sample

The probability sample was collected to represent the United States national sample.

Time Method

Longitudinal: Trend / Repeated Cross-section

Version History

2024-03-04 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Performed recodes and/or calculated derived variables.

Weight

Wave 1: WEIGHT was calculated based on the complete Wave 1 sample and should be used for most cross-sectional analyses of the Wave 1 sample (N=6,514). WEIGHT_C1, WEIGHT_C2, and WEIGHT_C3 are the cohort specific weights. These are the weights to use if doing any cohort specific analyses.

Wave 2: WEIGHTW2 was calculated based on the complete Wave 2 sample and should be used for most cross-sectional analyses of the Wave 2 sample (N=5,661) or when completing longitudinal analyses of Waves 1 and 2. WEIGHT_C1W2, WEIGHT_C2W2, and WEIGHT_C3W2 are the cohort specific weights. These are the weights to use if doing any cohort specific analyses.

Wave 3: WEIGHTCROSSW3 was calculated based on the complete Wave 3 sample and should be used for most cross-sectional analyses of the Wave 3 sample (N=4,881) or when completing longitudinal analyses of Waves 1 and 3. WEIGHTLONGW3 was calculated based on the complete sample of individuals who completed Waves 1, 2, and 3 (n=4,667) and should be used for longitudinal analyses of all three waves (if a complete case analysis is necessary).
