Predictors of willingness to get a COVID-19 vaccine in the U.S.

BACKGROUND: As COVID-19 vaccine distribution efforts continue, public health workers can strategize about vaccine promotion in an effort to increase willingness among those who may be hesitant. METHODS: In April 2020, we surveyed a national probability sample of 2279 U.S. adults using an online panel recruited through address-based sampling. Households received a computer and internet access if needed to participate in the panel. Participants were invited via e-mail and answered online survey questions about their willingness to get a novel coronavirus vaccine when one became available. The survey was completed in English and Spanish. We report weighted percentages. RESULTS: Most respondents were willing to get the vaccine for themselves (75%) or their children (73%). Notably, Black respondents were less willing than White respondents (47% vs. 79%, p < 0.001), while Hispanic respondents were more willing than White respondents (80% vs. 75%, p < 0.003). Females were less likely than makes (72% vs. 79%, p < 0.001). Those without insurance were less willing than the insured (47% vs. 78%, p < 0.001). Willingness to vaccinate was higher for those age 65 and older than for some younger age groups (85% for those 65 and older vs. 75% for those 50-64, p < 0.017; 72% for those 35-49, p < 0.002; 70% for those 25-34, p = NS and 75% for ages 18-24, p = NS), but other groups at increased risk because of underlying medical conditions or morbid obesity were not more willing to get vaccinated than their lower risk counterparts. CONCLUSIONS: Most Americans were willing to get a COVID-19 vaccine, but several vulnerable populations reported low willingness. Public health efforts should address these gaps as national implementation efforts continue.

Risk Adjustment, Mode Adjustment, and Nonresponse Bias Analysis on Quality Measures From a Long-Term Care Hospital Experience of Care Survey.

OBJECTIVES: To develop a patient risk adjustment model for experience of care (EOC) quality measures for long-term care hospitals (LTCHs) that includes mode of survey administration. To assess presence of nonresponse bias in the adjusted facility-level scores. DESIGN: We tested 3 modes of collecting the EOC data: mail-only, mixed (ie, mail with telephone follow-up), and in-facility. This study used sequential modeling and impact analysis, specified a risk and mode adjustment model, and evaluated presence of nonresponse after adjustment. SETTING: LTCHs. PARTICIPANTS: Patients (N=1364) and 69 LTCHs. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Risk and mode adjusted responses to 28 survey questions and 6 facility-level scores derived from survey responses. RESULTS: Mode of data collection and patient risk variables (age, sex, overall health, overall mental health, marital status, education, race, and whether a proxy responded) were included in the model. Clinical variables were not significant. The in-facility mode was associated with significantly higher performance scores than the other modes. When the recommended risk and mode adjustment model was applied, nonresponse bias was not observed in any mode. CONCLUSIONS: LTCH EOC data should be adjusted for patient risk variables including mode of data collection.

Americans' Attitudes Toward COVID-19 Preventive and Mitigation Behaviors and Implications for Public Health Communication.

PURPOSE: Identifying drivers of behavior is essential to develop effective messaging around COVID-19 prevention and mitigation. Our study assessed for behavioral antecedents of social distancing, wearing face coverings, and sheltering in place during the onset of the COVID-19 pandemic. Although ours is an early assessment, understanding motivation for behavior will remain critical as U.S. vaccination uptake has stalled and variants continue to pose a health threat. DESIGN: Cross-sectional survey; Setting: Online assessments in April 10-13 and 17-20, 2020; Subjects: 2,279 U.S. adults identified through a national, probability-based web panel (34% response rate). Measures: self-reported behavior, perceived effectiveness and risk, worry, social norms, and knowledge. ANALYSIS: Multivariable regression analyses. RESULTS: Most Americans reported social distancing (91%) and sheltering in place (86%). Just over half reported wearing face coverings (51%), whereas more (77%) said they intended to do so. Perceived effectiveness of the behavior was consistently associated with each outcome (OR = 2.34, 1.40, 2.11, respectively; all P < .01). Perceptions about the extent to which others should comply with behavior (social norms) were strongly associated with intentions to wear a face covering only (OR = 6.30, 95% CI 4.34-9.15; P < .001) and worry about getting COVID-19 was associated with sheltering in place and social distancing (OR = 2.63, 95% CI 1.15-5.00; 4.91, 95% CI 1.66, 14.50, respectively; all P < .05). CONCLUSION: Behavioral constructs were strongly associated with COVID-19 preventive and mitigation behaviors and have implications for communication.

Gaps in Knowledge About COVID-19 Among US Residents Early in the Outbreak.

OBJECTIVES: The novel coronavirus disease 2019 (COVID-19) resulting from severe acute respiratory syndrome coronavirus 2 began to affect the United States in early 2020. This study aimed to assess the US public's initial understanding about the disease and virus to inform public health communication efforts. METHODS: We conducted a survey of US households from February 28 through March 2, 2020, using a probability-based web-panel survey of 1021 US residents. To assess knowledge about COVID-19, we asked respondents a series of 16 true/false questions. We conducted descriptive statistics and linear regression analyses to examine differences in knowledge scores based on demographic and background characteristics. RESULTS: Knowledge about COVID-19 and the virus was relatively low overall at the beginning of the outbreak, with average scores of 62% on a 16-item knowledge index (ie, answers for 6 of the 16 questions were incorrect or unknown). Knowledge was especially low among people who had low education and income levels, were unemployed, were Hispanic, were non-Hispanic Black, were aged 18-24 and 35-49, indicated having "other" health insurance, and had limited exposure to information about the pandemic. Non-Hispanic Black respondents were less knowledgeable about COVID-19 and the virus at every education level compared with non-Hispanic White respondents at higher education levels. Non-Hispanic Black respondents with

Design and Operation of the National Survey of Children's Health, 2011-2012.

Objectives This report presents the development, plan, and operation of the 2011-2012 National Survey of Children's Health, a module of the State and Local Area Integrated Telephone Survey, conducted by the National Center for Health Statistics. Funding was provided by the Maternal and Child Health Bureau, Health Resources and Services Administration. The survey was designed to produce national and state prevalence estimates of the physical and emotional health of children aged 0-17 years, as well as factors that may relate to child well-being including medical homes, family interactions, parental health, school and after-school experiences, and neighborhood characteristics.

Design and operation of the National Survey of Children with Special Health Care Needs, 2009-2010.

OBJECTIVES: This report presents the development, plan, and operation of the 2009-2010 National Survey of Children with Special Health Care Needs, a module of the State and Local Area Integrated Telephone Survey. The survey is conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. This survey was designed to produce national and state-specific prevalence estimates of children with special health care needs (CSHCN), to describe the types of services that they need and use, and to assess aspects of the system of care for CSHCN. METHODS: A random-digit-dial sample of households with children under age 18 years was constructed for each of the 50 states and the District of Columbia. The sampling frame consisted of landline phone numbers and cellular(cell) phone numbers of households that reported a cell-phone-only or cell-phone-mainly status. Children in identified households were screened for special health care needs. If CSHCN were identified in the household, a detailed interview was conducted for one randomly selected child with special health care needs. Respondents were parents or guardians who knew about the children's health and health care. RESULTS: A total of 196,159 household screening interviews were completed from July 2009 through March 2011, resulting in 40,242 completed special-needs interviews, including 2,991 from cell-phone interviews. The weighted overall response rate was 43.7% for the landline sample, 15.2% for the cell-phone sample, and 25.5% overall.

Design and operation of the National Survey of Children's Health, 2007.

OBJECTIVES: This report presents the development, plan, and operation of the 2007 National Survey of Children's Health, a module of the State and Local Area Integrated Telephone Survey, conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. This survey was designed to produce national and state-specific prevalence estimates for a variety of physical, emotional, and behavioral health indicators and measures of children's experiences with the health care system. The survey also includes questions about the family (for example, parents' health status, stress and coping behaviors, family activities) and about respondents' perceptions of the neighborhoods where their children live. Funding and direction for this survey was provided by the Maternal and Child Health Bureau of the Health Resources and Services Administration. METHODS: A random-digit-dialed sample of households with children under age 18 years was selected from each of the 50 states and the District of Columbia. One child was randomly selected from all children in each identified household to be the subject of the survey. The respondent was a parent or guardian who knew about the child's health and health care. RESULTS: A total of 91,642 interviews were completed from April 2007 to July 2008. Nearly 80% of the interviews were completed in 2007. Interviews were completed in 66.0% of identified households with children. The weighted overall response rate was 46.7%. A data file has been released that contains demographic information on the selected child, substantive health and well-being data for the child and his or her family, and sampling weights. Estimates based on the sampling weights generalize to the noninstitutionalized population of children in each state and nationwide.

Design and operation of the National Survey of Adoptive Parents, 2007.

OBJECTIVE: This report presents the development, plan, and operation of the National Survey of Adoptive Parents (NSAP), a module of the State and Local Area Integrated Telephone Survey conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. NSAP was designed to produce national estimates of the characteristics, health, and well-being of adopted children and their families, the preadoption experiences of the adoptive parents, and their access to and utilization of postadoption supports and services. Funding for the survey was provided by the Office of the Assistant Secretary for Planning and Evaluation and the Administration for Children and Families, both of the Department of Health and Human Services. METHODS: The National Survey of Children's Health, 2007 (NSCH) was a random-digit-dial telephone survey of households with children under age 18 years. In households with more than one child, one child was randomly selected to be the subject of the interview. Children identified as adopted, who did not live with a biological parent and who lived in households where English was spoken, were eligible for the NSAP follow-up interview. The NSAP interview was a call-back scheduled at the end of the NSCH telephone interview. Sampled children included those adopted from other countries, from the U.S. foster care system, and from private domestic sources. Respondents were either the adoptive mother or the adoptive father. RESULTS: A total of 2,089 NSAP interviews were completed from April 2007 to July 2008. The interview completion rate (i.e., cooperation rate) for eligible respondents was 74.4%. The overall response rate, taking into account nonresponse to NSCH, was 34.6%.

Design and operation of the National Survey of Adoptive Parents of Children With Special Health Care Needs, 2008.

OBJECTIVE: This report presents the development, plan, and operation of the National Survey of Adoptive Parents of Children with Special Health Care Needs (NSAP-SN), a module of the State and Local Area Integrated Telephone Survey conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. The survey was designed to produce national estimates of the characteristics, health, and well-being of adopted children with special health care needs (CSHCN) and their families, the preadoption experiences of the adoptive parents, and their access to and utilization of postadoption services. Funding was provided by the Office of the Assistant Secretary for Planning and Evaluation and the Administration for Children and Families, both of the U.S. Department of Health and Human Services. METHODS: The National Survey of Children with Special Health Care Needs 2005-2006 (NS-CSHCN), a random-digit-dial telephone survey of households with children, included questions that identified whether the sampled child was adopted. Adopted CSHCN under age 18 in 2008 who lived in households where English was spoken were eligible for the NSAP-SN follow-up interview. The NSAP-SN interview was a follow-back telephone call 1 to 3 years after the original NS-CSHCN interview. Sampled children included CSHCN adopted from other countries, from the U.S. foster care system, and from private domestic sources. Respondents were either the adoptive mother or the adoptive father. RESULTS: A total of 1,007 NSAP-SN interviews were completed from February 2008 to July 2008. The interview completion rate (i.e., cooperation rate) for eligible respondents was 67.3%. The overall response rate, taking account of nonresponse to NS-CSHCN, was 37.7%.
