Despite recent attention to trust, comparatively little is known about distrust as distinct from trust. In this paper, we drew on case study data of a reorganized court of law, where intergroup distrust had grown between judges and administrators, to develop a dynamic theory of distrust. We used insights from the literatures on distrust, conflict escalation, and professional–organization relations to guide the analysis of our case data. Our research is consistent with insights on distrust previously postulated, but we were able to extend and make more precise the perceptions and behaviors that make up the elements of the self-amplifying cycle of distrust development, how these elements are related, and the mechanisms of amplification that drive the cycle. To help guide and focus future research, we modeled the process by which distrust emerges and develops, and we drew inferences on how it can be repaired.

Background People bring the social contexts of their lives into the medical encounter. As a social determinant of health, police brutality influences physical and mental health. However, negative experiences with institutions such as law enforcement might decrease trust in other institutions, including medical institutions. Mistrust might limit engagement with the healthcare system and affect population health. This study investigates the relationship between police brutality and medical mistrust and assesses whether it varies by race. Basic Procedures Data were obtained from a 2018 cross-sectional survey of adults living in urban areas in the USA ( N  = 4389). Medical mistrust was regressed on police brutality (experiences and appraisal of negative encounters with the police), controlling for socio-demographics, health status, and healthcare access. Means of mistrust were predicted by racial group after including interactions between police brutality and race. Main Findings Respondents who had negative encounters with the police, even if they perceived these encounters to be necessary, had higher levels of medical mistrust compared to those with no negative police encounters. Police brutality increased mistrust for all racial groups. Principal Conclusions Conditions outside the medical system such as experiencing police brutality impact relationships with the medical system. Given that clinicians are in a unique position of having access to firsthand information about the struggles and injustices that shape their patients’ health, advocating for systemic change on behalf of their patients might build trust.

An invisible threat has visibly altered the world. Governments and key institutions have had to implement decisive responses to the danger posed by the coronavirus pandemic. Imposed change will increase the likelihood that alternative explanations take hold. In a proportion of the general population there may be strong scepticism, fear of being misled, and false conspiracy theories. Our objectives were to estimate the prevalence of conspiracy thinking about the pandemic and test associations with reduced adherence to government guidelines. A non-probability online survey with 2501 adults in England, quota sampled to match the population for age, gender, income, and region. Approximately 50% of this population showed little evidence of conspiracy thinking, 25% showed a degree of endorsement, 15% showed a consistent pattern of endorsement, and 10% had very high levels of endorsement. Higher levels of coronavirus conspiracy thinking were associated with less adherence to all government guidelines and less willingness to take diagnostic or antibody tests or to be vaccinated. Such ideas were also associated with paranoia, general vaccination conspiracy beliefs, climate change conspiracy belief, a conspiracy mentality, and distrust in institutions and professions. Holding coronavirus conspiracy beliefs was also associated with being more likely to share opinions. In England there is appreciable endorsement of conspiracy beliefs about coronavirus. Such ideas do not appear confined to the fringes. The conspiracy beliefs connect to other forms of mistrust and are associated with less compliance with government guidelines and greater unwillingness to take up future tests and treatment.

Our aim was to estimate provisional willingness to receive a coronavirus 2019 (COVID-19) vaccine, identify predictive socio-demographic factors, and, principally, determine potential causes in order to guide information provision. A non-probability online survey was conducted (24th September-17th October 2020) with 5,114 UK adults, quota sampled to match the population for age, gender, ethnicity, income, and region. The Oxford COVID-19 vaccine hesitancy scale assessed intent to take an approved vaccine. Structural equation modelling estimated explanatory factor relationships. 71.7% ( =3,667) were willing to be vaccinated, 16.6% ( =849) were very unsure, and 11.7% ( =598) were strongly hesitant. An excellent model fit (RMSEA=0.05/CFI=0.97/TLI=0.97), explaining 86% of variance in hesitancy, was provided by beliefs about the collective importance, efficacy, side-effects, and speed of development of a COVID-19 vaccine. A second model, with reasonable fit (RMSEA=0.03/CFI=0.93/TLI=0.92), explaining 32% of variance, highlighted two higher-order explanatory factors: 'excessive mistrust' ( =0.51), including conspiracy beliefs, negative views of doctors, and need for chaos, and 'positive healthcare experiences' ( =-0.48), including supportive doctor interactions and good NHS care. Hesitancy was associated with younger age, female gender, lower income, and ethnicity, but socio-demographic information explained little variance (9.8%). Hesitancy was associated with lower adherence to social distancing guidelines. COVID-19 vaccine hesitancy is relatively evenly spread across the population. Willingness to take a vaccine is closely bound to recognition of the collective importance. Vaccine public information that highlights prosocial benefits may be especially effective. Factors such as conspiracy beliefs that foster mistrust and erode social cohesion will lower vaccine up-take.

The associations among normal personality and many mental disorders are well established, but it remains unclear whether and how symptoms of schizophrenia and schizotypal traits align with the personality taxonomy. This study examined the joint factor structure of normal personality, schizotypy, and schizophrenia symptoms in people with psychotic disorders (n = 288) and never-psychotic adults (n = 257) in the Suffolk County Mental Health Project. First, we evaluated the structure of schizotypal (positive schizotypy, negative schizotypy, and mistrust) and normal traits. In both the psychotic-disorder and never-psychotic groups, the best-fitting model had 5 factors: neuroticism, extraversion, conscientiousness, agreeableness, and psychoticism. The schizotypy traits were placed on different dimensions: negative schizotypy went on (low) extraversion, whereas positive schizotypy and mistrust went on psychoticism. Next, we added symptoms to the model. Numerous alternatives were compared, and the 5-factor model remained best-fitting. Reality distortion (hallucinations and delusions) and disorganization symptoms were placed on psychoticism, and negative symptoms were placed on extraversion. Models that separated symptom dimensions from trait dimensions did not fit well, arguing that taxonomies of symptoms and traits are aligned. This is the first study to show that symptoms of psychosis, schizotypy, and normal personality reflect the same underlying dimensions. Specifically, (low) extraversion, negative schizotypy, and negative symptoms form one spectrum, whereas psychoticism, positive schizotypy, and positive and disorganized symptoms form another. This framework helps to understand the heterogeneity of psychosis and comorbidity patterns found in psychotic disorders. It also underscores the importance of traits to understanding these disorders.

In recent years, medical journals have emphasized the increasingly critical role that social media plays in the dissemination of public health information and disease prevention guidelines. However, platforms such as Facebook and Twitter continue to pose unique challenges for clinical health care providers and public health officials alike. In order to effectively communicate during public health emergencies, such as the COVID-19 pandemic, it is increasingly critical for health care providers and public health officials to understand how patients gather health-related information on the internet and adjudicate the merits of such information. With that goal in mind, we conducted a survey of 1003 US-based adults to better understand how health consumers have used social media to learn and stay informed about the COVID-19 pandemic, the extent to which they have relied on credible scientific information sources, and how they have gone about fact-checking pandemic-related information. A web-based survey was conducted with a sample that was purchased through an industry-leading market research provider. The results were reported with a 95% confidence level and a margin of error of 3. Participants included 1003 US-based adults (aged ≥18 years). Participants were selected via a stratified quota sampling approach to ensure that the sample was representative of the US population. Balanced quotas were determined (by region of the country) for gender, age, race, and ethnicity. The results showed a heavy reliance on social media during the COVID-19 pandemic; more than three-quarters of respondents (762/1003, 76%) reported that they have relied on social media at least \"a little,\" and 59.2% (594/1003) of respondents indicated that they read information about COVID-19 on social media at least once per week. According to the findings, most social media users (638/1003, 63.6%) were unlikely to fact-check what they see on the internet with a health professional, despite the high levels of mistrust in the accuracy of COVID-19-related information on social media. We also found a greater likelihood of undergoing vaccination among those following more credible scientific sources on social media during the pandemic (χ =50.790; φ=0.258; P<.001). The findings suggest that health professionals will need to be both strategic and proactive when engaging with health consumers on social media if they hope to counteract the deleterious effects of misinformation and disinformation. Effective training, institutional support, and proactive collaboration can help health professionals adapt to the evolving patterns of health information seeking.

Uptake of pre-exposure prophylaxis (PrEP) among Black women living in the US is suboptimal. We sought to determine the association between HIV-related medical mistrust (or belief in HIV conspiracy theories) and willingness to use PrEP among Black women. We analyzed data from the 2016 National Survey on HIV in the Black Community (NSHBC), a nationally representative cross-sectional survey. Among NSHBC participants, 522 were women and 347 (69.0%) reported HIV risk factors. Only 14.1% were aware that PrEP exists; 30.8% reported willingness to use PrEP. HIV-related medical mistrust was reported by 60.4% of women. In multivariable analysis, controlling for income, education, marital status and health care engagement, belief in conspiracy theories was significantly associated with higher willingness to use PrEP. The HIV-Related Medical Mistrust Scale item: “there is a cure for HIV, but the government is withholding it from the poor” was independently associated with higher PrEP willingness. This finding speaks to the need for an improved understanding of the role of HIV-related medical mistrust among Black women to improve uptake of biomedical HIV prevention.

•Categorized vaccine hesitancy into watchful, skeptics, and system distrusters.•Unvaccinated adults are younger and have lower education and income.•Adults who voted for Trump are less likely to be vaccinated.•Adults who voted for Trump have higher skepticism and distrust.•Females, non-Hispanic Black, and unmarried adults are most likely to be watchful. COVID-19 vaccine hesitancy is complex, with adults identifying various reasons for not getting vaccinated. Using data from the 2022 National Wellbeing Survey on 7612 U.S. adults aged 18–64, we identified how age, race/ethnicity, sex, marital status, education, income, employment status, partisanship, and metropolitan status are associated with COVID-19 vaccination status and three non-mutually exclusive types of vaccine hesitancy: 1) watchful, concerned about vaccine side effects and efficacy; 2) skeptics, distrust the vaccine, and 3) system distrusters, distrust government. A third of respondents overall (N = 2643) had not received at least one dose at the time of the survey. Among respondents who were not vaccinated, 67 % are classified as watchful, 53 % are skeptics, and 32 % are system distrusters. Results from logistic regression show that concerns about side effects and safety (watchfulness) appear to be major drivers for not getting vaccinated among females and among non-Hispanic Black and unmarried adults, whereas skepticism and distrust appear to be more important barriers among ages 25–44. All three types of hesitancy appear to be important contributors to lower vaccination uptake among low-income, low-education, and unemployed adults, and among individuals who voted for Donald Trump in the 2020 election (with skepticism and distrust being most endorsed by this group). Findings suggest that universal messaging and intervention strategies are unlikely to be effective in reducing vaccine hesitancy. Different messages, messengers, and tactics must be used with different groups.

Racially or ethnically targeted events may have adverse health implications for members of the group not directly targeted, a phenomenon known as peripheral trauma. Recent evidence suggests that mass incarceration, police brutality, and immigration actions all have such effects, as did medical exploitation by the US government during the Tuskegee Study of Untreated Syphilis in the Negro Male. We summarize recent findings in the economics literature on population-level effects of the Tuskegee study, including a decline in health-seeking behavior and a rise of both mortality and medical mistrust among African-American men not enrolled in the study. We highlight the relevance of our findings for present-day racial health disparities. Practitioner awareness of peripheral trauma is an important element of cultural competency. But among options to substantially improve minority trust in the healthcare system, the diversification of medical practitioners may hold greatest promise.
