The Role of Social Circle Perceptions in "False Consensus" about Population Statistics: Evidence from a National Flu Survey.

ABSTRACT: Purpose. "False consensus" refers to individuals with (v. without) an experience judging that experience as more (v. less) prevalent in the population. We examined the role of people's perceptions of their social circles (family, friends, and acquaintances) in shaping their population estimates, false consensus patterns, and vaccination intentions. Methods. In a national online flu survey, 351 participants indicated their personal vaccination and flu experiences, assessed the percentage of individuals with those experiences in their social circles and the population, and reported their vaccination intentions. Results. Participants' population estimates of vaccination coverage and flu prevalence were associated with their perceptions of their social circles' experiences, independent of their own experiences. Participants reporting less social circle "homophily" (or fewer social contacts sharing their experience) showed less false consensus and even "false uniqueness." Vaccination intentions were greater among nonvaccinators reporting greater social circle vaccine coverage. Discussion. Social circle perceptions play a role in population estimates and, among individuals who do not vaccinate, vaccination intentions. We discuss implications for the literature on false consensus, false uniqueness, and social norms interventions.

Project description:BACKGROUND:Vaccination against seasonal influenza (SIV) is recommended for patients with diabetes, but their vaccination coverage is unsatisfactory in France and elsewhere. This qualitative survey of people with diabetes sought to explore 1) the extent to which SIV-related behaviour is more or less automatic; 2) reasons they choose/reject SIV; 3) their trust/distrust in authorities, science, and medicine. METHODS:We conducted semi-structured in-depth interviews of 19 adults with diabetes in 2014. We recruited them through physicians or patient associations and implemented an analysis of thematic content. RESULTS:Eight patients were vaccinated against flu in the preceding flu season and 11 were not. SIV uptake and refusal were stable over time and justified by multiple arguments. Coupons for free vaccines and regular doctor visits contributed to the habit of vaccination. Vaccination decisions were frequently anchored in past experiences of influenza and its vaccine. Patients often justified non-vaccination with attitudes of trivialisation/relativisation of influenza-associated risks and the perception that these can be controlled by means other than vaccination (e.g., through the avoidance of exposure). Some misbeliefs (e.g., SIV causes influenza) and doubts about SIV effectiveness and safety also existed. Several patients reported increased mistrust of SIV since the A/H1N1 pandemic in 2009. Patients trusted their doctors strongly regardless of their SIV behaviour, but unvaccinated patients had little trust in the government and pharmaceutical companies. Some discordances were found between perceptions and behaviour (e.g., remaining vaccinated despite doubts about SIV effectiveness or remaining unvaccinated despite feelings of vulnerability towards influenza complication), suggesting the existence of some vaccine hesitancy among patients. CONCLUSION:This study among patients with diabetes suggest that SIV uptake is stable, thanks to a favourable environment. Nonetheless, SIV refusal is also stable over time. Unvaccinated patients used multiple arguments to justify SIV refusal, including compensatory health beliefs. Physicians should take every opportunity to recommend SIV. The necessary individualised patient education regarding SIV requires better physician training in patients priorities. While almost all patients strongly trust their doctors, unvaccinated patients distrust distal stakeholders: it is absolutely essential to restore trust in them and to develop new more effective influenza vaccines.

Project description:BackgroundLimited COVID-19 vaccination acceptance among healthcare assistants (HCAs) may adversely impact older adults, who are at increased risk for severe COVID-19 infections. Our study objective was to evaluate the perceptions of COVID-19 vaccine safety and efficacy in a sample of frontline HCAs, overall and by race and ethnicity.MethodsAn online survey was conducted from December 2020 to January 2021 through national e-mail listserv and private Facebook page for the National Association of Health Care Assistants. Responses from 155 HCAs, including certified nursing assistants, home health aides, certified medical assistants, and certified medication technicians, were included. A 27-item survey asked questions about experiences and perceptions of COVID-19 vaccines, including how confident they were that COVID-19 vaccines are safe, effective, and adequately tested in people of color. Multivariable regression was used to identify associations with confidence in COVID-19 vaccines.ResultsWe analyzed data from 155 completed responses. Among respondents, 23.9% were black and 8.4% Latino/a. Most respondents worked in the nursing home setting (53.5%), followed by hospitals (12.9%), assisted living (11.6%), and home care (10.3%). Respondents expressed low levels of confidence in COVID-19 vaccines, with fewer than 40% expressing at least moderate confidence in safety (38.1%), effectiveness (31.0%), or adequate testing in people of color (27.1%). Non-white respondents reported lower levels of confidence in adequate testing of vaccines compared to white respondents. In bivariate and adjusted models, respondents who gave more favorable scores of organizational leadership at their workplace expressed greater confidence in COVID-19 vaccines.ConclusionFrontline HCAs reported low confidence in COVID-19 vaccines. Stronger organizational leadership in the workplace appears to be an important factor in influencing HCA's willingness to be vaccinated. Action is needed to enhance COVID-19 vaccine uptake in this important population with employers playing an important role to build vaccine confidence and trust among employees.
