Information avoidance: An interchangeable strategy of self-protection.

Across two studies, using five samples (N = 1,850), we examined whether health information avoidance-the deliberate decision to remain ignorant of available but unwanted personal health information-serves a defensive purpose and is interchangeable with other defensive strategies. We tested this idea by examining the relationship between health information avoidance-both as a dispositional tendency and deliberate decision-and feedback derogation. In Study 1, we experimentally demonstrated that a situation known to reduce defensiveness-self-uncertainty-decreased both proactive avoidance and reactive defensiveness relative to a control group. Study 2 demonstrated, across four samples, that people with a greater defensive orientation toward personal health information were more likely to derogate health information. These results are consistent with the idea that feedback derogation replaced the decision to avoid feedback. Together, results suggest that health information avoidance is likely part of a broader self-protective system and is replaceable with other motivated self-protection strategies.

Self-administered mindfulness interventions reduce stress in a large, randomized controlled multi-site study.

Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ ; retrospective registration at ClinicalTrials.gov NCT06308744 ) multi-site study (nsites = 37, nparticipants = 2,239, 70.4% women, Mage = 22.4, s.d.age = 10.1, all fluent English speakers), we experimentally tested whether four single, standalone mindfulness exercises effectively reduced stress, using Bayesian mixed-effects models. All exercises proved to be more efficacious than the active control. We observed a mean difference of 0.27 (d = -0.56; 95% confidence interval, -0.43 to -0.69) between the control condition (M = 1.95, s.d. = 0.50) and the condition with the largest stress reduction (body scan: M = 1.68, s.d. = 0.46). Our findings suggest that mindfulness may be beneficial for reducing self-reported short-term stress for English speakers from higher-income countries.

Plasma apolipoprotein E levels, isoform composition, and dimer profile in relation to plasma lipids in racially diverse patients with Alzheimer's disease and mild cognitive impairment.

BACKGROUND: The APOEε4-promoted risk of Alzheimer's disease (AD) is lower in Black/African-Americans (B/AAs), compared to non-Hispanic whites (NHWs). Previous studies reported lower plasma apolipoprotein E (apoE) levels in NHW APOEε4-carriers compared to non-carriers, and low plasma apoE levels were directly associated with an increased risk of AD and all dementia. We further showed that APOEε3/ε3 AD patients exhibited reduced plasma apoE dimers compared to corresponding control subjects. Whether plasma apoE levels and apoE dimer formation differ between races/ethnicities and therefore may help explain AD risk racial disparity remains to be elucidated. METHODS: Using mass spectrometry, we determined total plasma apoE and apoE isoform levels in a cohort of B/AAs (n = 58) and NHWs (n = 67) including subjects with normal cognition (B/AA: n = 25, NHW: n = 28), mild cognitive impairment (MCI) (B/AA: n = 24, NHW: n = 24), or AD dementia (B/AA: n = 9, NHW: n = 15). Additionally, we used non-reducing western blot analysis to assess the distribution of plasma apoE into monomers/disulfide-linked dimers. Plasma total apoE, apoE isoform levels, and % apoE monomers/dimers were assessed for correlations with cognition, cerebrospinal fluid (CSF) AD biomarkers, sTREM2, neurofilament light protein (NfL), and plasma lipids. RESULTS: Plasma apoE was predominantly monomeric in both racial groups and the monomer/dimer distribution was not affected by disease status, or correlated with CSF AD biomarkers, but associated with plasma lipids. Plasma total apoE levels were not related to disease status and only in the NHW subjects we observed lower plasma apoE levels in the APOEε4/ε4-carriers. Total plasma apoE levels were 13% higher in B/AA compared to NHW APOEε4/ε4 subjects and associated with plasma high-density lipoprotein (HDL) in NHW subjects but with low-density lipoprotein levels (LDL) in the B/AA subjects. Higher plasma apoE4 levels, exclusively in APOEε3/ε4 B/AA subjects, were linked to higher plasma total cholesterol and LDL levels. In the controls, NHWs and B/AAs exhibited opposite associations between plasma apoE and CSF t-tau. CONCLUSIONS: The previously reported lower APOEε4-promoted risk of AD in B/AA subjects may be associated with differences in plasma apoE levels and lipoprotein association. Whether differences in plasma apoE levels between races/ethnicities result from altered APOEε4 expression or turnover, needs further elucidation.

Surviving Racism and Sexism: What Votes in the Television Program Survivor Reveal About Discrimination.

We examined whether there is evidence for racial and gender bias in the voting patterns of contestants on Survivor, a reality-television zero-sum game in which contestants compete for up to 39 days to win $1 million. Among 731 contestants across 40 seasons, we found evidence of racial and gender bias at multiple stages of Survivor. Compared with men, women were more likely to be voted out of their tribe first and were less likely to make it to the individual-competition stage of the game (i.e., the "merge"). They were also less likely to win Survivor. Black, Indigenous, and people of color (BIPOC) contestants, compared with White contestants, were more likely to be voted out of their tribe first and were less likely to make it to the individual-competition stage of the game. These findings suggest a systemic bias in favor of White men and against women of color.

Comparing Foodie Calls in Poland, the United Kingdom, and the United States: A Registered Replication Report.

Collisson et al. (2020) found Dark Triad traits and gender role beliefs predicted "foodie calls," a phenomenon where people go on a date with others, to whom they are not attracted, for a free meal. Because gender roles and dating norms differ across cultures, we conducted a registered replication across different cultures by surveying 1838 heterosexual women from Poland, the United Kingdom (UK), and the United States (US). Relying on the structural equation modeling, as conducted in the original study, our findings revealed gender role beliefs best predicted foodie calls and their perceived acceptability, whereas the Dark Triad's general factor was nonsignificant. Analyses at the country level yielded mixed results. The original findings were replicated in the UK and Poland, but not in the US, where only narcissism predicted foodie calls. In the US, gender role beliefs predicted foodie call acceptability, but the Dark Triad general factor did not. Potential reasons for why traditional gender roles, but not the Dark Triad, predicted foodie calls in the US are discussed.

Implicit and explicit COVID-19 associations and mental health in the United States: a large-scale examination and replication.

BACKGROUND: Given the sensitive nature of COVID-19 beliefs, evaluating them explicitly and implicitly may provide a fuller picture of how these beliefs vary based on identities and how they relate to mental health. OBJECTIVE: Three novel brief implicit association tests (BIATs) were created and evaluated: two that measured COVID-19-as-dangerous (vs. safe) and one that measured COVID-19 precautions-as-necessary (vs. unnecessary). Implicit and explicit COVID-19 associations were examined based on individuals' demographic characteristics. Implicit associations were hypothesized to uniquely contribute to individuals' self-reports of mental health. METHODS: Participants (N = 13,413 US residents; April-November 2020) were volunteers for a COVID-19 study. Participants completed one BIAT and self-report measures. This was a preregistered study with a planned internal replication. RESULTS: Results revealed older age was weakly associated with stronger implicit and explicit associations of COVID-as-dangerous and precautions-as-necessary. Black and Asian individuals reported greater necessity of taking precautions than White individuals (with small-to-medium effects); greater education was associated with greater explicit reports of COVID-19-as-dangerous and precautions-as-necessary with small effects. Replicated relationships between COVID-as-dangerous explicit associations and mental health had very small effects. CONCLUSIONS: Implicit associations did not predict mental health but there was evidence that stronger COVID-19-as-dangerous explicit associations are weakly associated with worse mental health.

Eating together more but feeling worse: Discrepancies between observed and reported well-being of Latino(a/x) students at a Hispanic-Serving Institution.

Objective. Past research suggests that eating alone is associated with less social support and poorer physical health. The current study examines the comparative health and well-being of Hispanic/Latino(a/x) and non-Hispanic/Latino(a/x) students, with a focus on comparing self-reported well-being to the observed marker of social well-being that is eating alone.Participants. Undergraduate students from a college dining hall completed online surveys in exchange for a gift card.Methods. Participants completed measures of eating alone in the dining hall, food choices, social support, quality of life, and overall health.Results. Although, compared to their non-Hispanic/Latino(a/x) peers, Hispanic/Latino(a/x) students were much more likely to be eating with others, both groups reported similar levels of social support and life satisfaction. Furthermore, Hispanic/Latino(a/x) students reported poorer physical health and chose unhealthier meals.Conclusion. Although Hispanic/Latino(a/x) students appeared to be more socially connected than their peers, these connections did not translate to better well-being.

Associations between perceived everyday discrimination and health among college students at a Hispanic-serving institution.

Despite efforts by universities to promote racial/ethnic, gender, and socioeconomic diversity, college students continue to report discrimination. In two studies, we examined the frequency, predictors, and health consequences of experiencing everyday discrimination at a Hispanic-Serving Institution. Findings show the majority of students reported experiencing discrimination at the university, with most experiences attributed to their gender and aspects of their physical appearance. More frequent discrimination was associated with poorer physical and psychological health. Furthermore, most participants cited other students as the source of their discrimination. These findings offer important insight into students' experiences of everyday discrimination at a diverse setting.

Uncertainty in healthcare and health decision making: Five methodological and conceptual research recommendations from an interdisciplinary team.

Uncertainty is prevalent in various health contexts. It is imperative to understand how health-related uncertainty can impact individuals' healthcare experiences and health decision making. The purpose of the present paper is to provide five overarching recommendations from an interdisciplinary team of experts to address gaps in the literature on health-related uncertainty. We present a case study of health-related uncertainty within the specific context of alcohol use to demonstrate these gaps and provide context for the recommendations. The five recommendations concerning health-related uncertainty include: (1) use common, consistent terminology to discuss uncertainty, (2) clarify measures of individual differences in response to uncertainty, (3) increase research on uncertainty and affect, (4) investigate the impact of the channel through which uncertainty is communicated, and (5) develop theory-driven interventions to improve uncertainty management. We conclude by reviewing health contexts in which health-related uncertainty exists and note how our recommendations complement existing reviews and data.

The role of uncertainty, worry, and control in well-being: Evidence from the COVID-19 outbreak and pandemic in U.S. and China.

Uncertainty about the future often leads to worries about what the future will bring, which can have negative consequences for health and well-being. However, if worry can act as a motivator to promote efforts to prevent undesirable future outcomes, those negative consequences of worry may be mitigated. In this article, we apply a novel model of uncertainty, worry, and perceived control to predict psychological and physical well-being among four samples collected in China (Study 1; during the early COVID-19 outbreak in China) and the United States (Studies 2-4, during 4 weeks in May 2020, 4 weeks in November 2020, and cross-sectionally between April and November 2020). Grounded in the feeling-is-for-doing approach to emotions, we hypothesized (and found) that uncertainty about one's COVID-19 risk would predict greater worry about the virus and one's risk of contracting it, and that greater worry would in turn predict poorer well-being. We also hypothesized, and found somewhat mixed evidence, that perceptions of control over 1's COVID-19 risk moderated the relationship between worry and well-being such that worry was related to diminished well-being when people felt they lacked control over their risk for contracting the virus. This study is one of the first to demonstrate an indirect path from uncertainty to well-being via worry and to demonstrate the role of control in moderating whether uncertainty and worry manifest in poor well-being.

Understanding parental vaccine refusal: Implicit and explicit associations about vaccines as potential building blocks of vaccine beliefs and behavior.

OBJECTIVE: A movement of parents refusing vaccines for their children has contributed to increasingly large outbreaks of diseases that are preventable by vaccines. Research has identified multiple factors that relate to parents' vaccination behaviors (i.e., whether not they vaccinate their children), including their beliefs about vaccines' safety and utility and their trust in those who recommend vaccines. Here we examine the role of more fundamental psychological processes that may contribute to multiple vaccine-related beliefs and behaviors: cognitive associations. METHODS: Using a large sample of U.S. parents (pre-COVID-19), we investigated parents' associations between vaccines and helpfulness/harmfulness, as well as between the self and vaccines (vaccine identity), and their relation to parents' beliefs about vaccine safety and utility, trust in authorities' vaccine recommendations, and prior vaccination refusal for their children. To capture a more complete understanding of people's associations, we examined both explicit associations (measured via self-report) and implicit associations (measured by the Implicit Association Test). RESULTS: Both implicit and explicit associations correlated with beliefs, trust, and vaccination refusal. Results from structural equation models indicated that explicit vaccine-identity and vaccine-helpfulness associations and implicit vaccine helpfulness associations were indirectly related to vaccination refusal via their relation with vaccine beliefs. CONCLUSIONS: Collectively, study findings suggest that vaccine associations-especially those related to helpfulness/harmfulness-may serve as psychological building blocks for parental vaccine beliefs and behaviors.

YKL-40 changes are not detected in post-mortem brain of patients with Alzheimer's disease and frontotemporal lobar degeneration.

BACKGROUND: YKL-40 (Chitinase 3-like I) is increased in CSF of Alzheimer's disease (AD) and frontotemporal lobar degeneration (FTLD) patients and is therefore considered a potential neuroinflammatory biomarker. Whether changed YKL-40 levels in the CSF reflect dysregulation of YKL-40 in the brain is not completely understood yet. We aimed to extensively analyze YKL-40 levels in the brain of AD and different FTLD pathological subtypes. The direct relationship between YKL-40 levels in post-mortem brain and ante-mortem CSF was examined in a small set of paired brain-CSF samples. METHOD: YKL-40 was analyzed in post-mortem temporal and frontal cortex of non-demented controls and patients with AD and FTLD (including FTLD-Tau and FTLD-TDP) pathology by immunohistochemistry (temporal cortex: 51 controls and 56 AD and frontal cortex: 7 controls and 24 FTLD patients), western blot (frontal cortex: 14 controls, 5 AD and 67 FTLD patients), or ELISA (temporal cortex: 11 controls and 7 AD and frontal cortex: 14 controls, 5 AD and 67 FTLD patients). YKL-40 levels were also measured in paired post-mortem brain and ante-mortem CSF samples from dementia patients (n = 9, time-interval collection: 1.4 years) by ELISA. RESULTS: We observed that YKL-40 post-mortem brain levels were similar between AD, FTLD, and controls as shown by immunohistochemistry, western blot, and ELISA. Interestingly, strong YKL-40 immunoreactivity was observed in AD cases with cerebral amyloid angiopathy (CAA; n = 6). In paired CSF-brain samples, YKL-40 concentration was 8-times higher in CSF compared to brain. CONCLUSION: Our data suggest that CSF YKL-40 changes may not reflect YKL-40 changes within AD and FTLD pathological brain areas. The YKL-40 reactivity associated with classical CAA hallmarks indicates a possible relationship between YKL-40, neuroinflammation, and vascular pathology.

High impact: Examining predictors of faculty-undergraduate coauthored publication and presentation in psychology.

Despite the increasing popularity of faculty-undergraduate research, a dearth of research has investigated factors that predict the professional outcomes of these collaborations. We sought to address this gap by examining a wide range of institutional (e.g., institution type, selectivity, course load) and faculty variables (e.g., rank, years of experience, enjoyment of mentoring) potentially related to coauthored undergraduate publication and conference presentation in psychology. Negative binomial regressions were used to analyze online survey data from 244 faculty members from both graduate-serving institutions (i.e., doctoral, master's) and primarily undergraduate institutions. The results showed that, after controlling for overall research productivity, faculty at primarily undergraduate institutions were more likely to publish journal articles with undergraduates, whereas faculty at graduate-serving institutions were more likely to coauthor conference presentations with undergraduates. Institutions with higher selectivity, more support for faculty-undergraduate research, and lower course loads produced higher numbers of undergraduate publications. Faculty characteristics were even more strongly related to undergraduate research outcomes. Specifically, publication was most likely with faculty who are of higher rank, have more years of experience, spend more time on research, foster close collaborative relationships with undergraduates, and/or perceive their students as high quality and well trained. By contrast, conference presentation was most likely with faculty who work with more undergraduate students on more projects per year and/or who enjoying mentoring undergraduates. Our findings suggest ways that institutions can facilitate undergraduate publication, which we argue is an increasingly common and achievable outcome.

Social Threat Reduces Alcohol Consumption among College Students.

AIMS: Past research suggests that people report a greater desire to consume alcohol when they experience social threat-or threats to their social selves, such as social exclusion. Nevertheless, experimental research on the role of social threat in alcohol consumption is limited. The present study examined the causal relationship between social threat and wine consumption. METHODS: Undergraduate students (N = 83; Mage = 21.8 years old, SDage = 1.62 years old; 72.3% women; 61.4% Latinx/Hispanic) participated in a study under the pretense that they were in a focus group gauging students' opinions of a bar being constructed at their university. During the study, participants and two confederate researchers completed a group activity in which they selected design elements for the bar. Participants were randomly assigned to one of two conditions. In the social threat condition, confederates rejected participants' design choices and socially excluded them during a follow-up task. In the social acceptance condition, confederates supported participants' choices and did not socially exclude them. All participants then completed a wine taste test. RESULTS: Contrary to predictions, an independent-samples t-test revealed that participants who experienced social threat consumed significantly less wine than those who were socially accepted, t(81) = -2.22, P = 0.03, d = -0.49. Furthermore, a linear regression test revealed that this effect persisted even when controlling for typical alcohol-consumption behavior, b = 56.09, t = -2.50, P = 0.02, d = -0.61. CONCLUSION: The relationship between social threat and alcohol consumption may be more nuanced than anticipated. Discussion centers around two potential moderators including positive affect and identity.

Impact of COVID-19 forecast visualizations on pandemic risk perceptions.

People worldwide use SARS-CoV-2 (COVID-19) visualizations to make life and death decisions about pandemic risks. Understanding how these visualizations influence risk perceptions to improve pandemic communication is crucial. To examine how COVID-19 visualizations influence risk perception, we conducted two experiments online in October and December of 2020 (N = 2549) where we presented participants with 34 visualization techniques (available at the time of publication on the CDC's website) of the same COVID-19 mortality data. We found that visualizing data using a cumulative scale consistently led to participants believing that they and others were at more risk than before viewing the visualizations. In contrast, visualizing the same data with a weekly incident scale led to variable changes in risk perceptions. Further, uncertainty forecast visualizations also affected risk perceptions, with visualizations showing six or more models increasing risk estimates more than the others tested. Differences between COVID-19 visualizations of the same data produce different risk perceptions, fundamentally changing viewers' interpretation of information.

Long Curriculum 3.0 in Resident Education: Comprehensive Curriculum in Pediatric and Adolescent Gynecology for Postgraduate Trainees in Obstetrics/Gynecology, Pediatrics, and Adolescent Medicine.

In 2015, the Resident Education Committee of the North American Society for Pediatric and Adolescent Gynecology published the Long Curriculum in Resident Education to provide educators with a comprehensive document to be used in postgraduate medical education. The original curriculum was designed to meet the resident learning objectives for the Council on Resident Education in Obstetrics and Gynecology, the American Board of Pediatrics, and the Royal College of Physicians and Surgeons of Canada and to provide a more intensive, broader learning experience. The curriculum was updated in 2018. This Committee Document is the third updated version (3.0) of the Long Curriculum in Resident Education.

Coping self-efficacy influences health information avoidance.

Avoiding information about one's health can have long-term implications for health and well-being. Two studies examined the relationship between health information avoidance and coping self-efficacy, or a sense that one can effectively cope. In Study 1, coping self-efficacy, but not general self-efficacy, was associated with information avoidance. In Study 2, participants who reflected on their positive coping strategies were less likely to avoid learning their risk for disease as compared to those who did not reflect on their coping strategies. These findings suggest that coping self-efficacy is a good target for future interventions aimed at reducing health information avoidance.
