RESUMEN

Does repeated exposure to climate-skeptic claims influence their acceptance as true, even among climate science endorsers? Research with general knowledge claims shows that repeated exposure to a claim increases its perceived truth when it is encountered again. However, motivated cognition research suggests that people primarily endorse what they already believe. Across two experiments, climate science endorsers were more likely to believe claims that were consistent with their prior beliefs, but repeated exposure increased perceptions of truth for climate-science and climate-skeptic claims to a similar extent. Even counter-attitudinal claims benefit from previous exposure, highlighting the insidious effect of repetition.

RESUMEN

The COVID-19 pandemic resulted in significant disruptions for children and youth around the world, especially given school closures and shifts in teaching modes (on-line and hybrid). However, the impact of these disruptions remains unclear given data limitations such as a reliance on cross-sectional and/or short-interval surveys as well as a lack of broad indicators of key outcomes of interest. The current research employs a quasi-experimental design by using an Australian four-year longitudinal survey with student responses from Grade 7 to 10 (aged 12-15 years old) (N = 8,735 from 20 schools) in one education jurisdiction. Responses are available pre-pandemic (2018 and 2019) and during the pandemic (2020 and 2021). Importantly the survey included measures of well-being, mental health and learning engagement as well as potential known school-environment factors that could buffer against adversity: school climate and school identification. The findings were generally in line with key hypotheses; 1) during COVID-19 students' learning engagement and well-being significantly declined and 2) students with more positive school climate or stronger school identification pre-COVID-19 fared better through the disruption of the pandemic. However, these same students suffered from a steeper decline in well-being and engagement which may be explained through the impact of losing meaningful social or group connections. This decline was evident after controlling for gender, academic grade (as a proxy of age), parental education, and socioeconomic status. It is concluded that investing in the social environment of schools is important in crisis preparedness and can facilitate better crisis response among youth.

RESUMEN

BACKGROUND: Scott syndrome is a mild platelet-type bleeding disorder, first described in 1979, with only 3 unrelated families identified through defective phosphatidylserine (PS) exposure and confirmed by sequencing. The syndrome is distinguished by impaired surface exposure of procoagulant PS on platelets after stimulation. To date, platelet function and thrombin generation in this condition have not been extensively characterized. OBJECTIVES: Genetic and functional studies were undertaken in a consanguineous family with a history of excessive bleeding of unknown cause. METHODS: A targeted gene panel of known bleeding and platelet genes was used to identify possible genetic variants. Platelet phenotyping, flow adhesion, flow cytometry, whole blood and platelet-rich plasma thrombin generation, and specialized extracellular vesicle measurements were performed. RESULTS: We detected a novel homozygous frameshift variant, c.1943del (p.Arg648Hisfs∗23), in ANO6 encoding Anoctamin 6, in a patient with a bleeding history but interestingly with normal ANO6 expression. Phenotyping of the patient's platelets confirmed the absence of PS expression and procoagulant activity but also revealed other defects including reduced platelet δ granules, reduced ristocetin-mediated aggregation and secretion, and reduced P-selectin expression after stimulation. PS was absent on spread platelets, and thrombi formed over collagen at 1500/s. Reduced thrombin generation was observed in platelet-rich plasma and confirmed in whole blood using a new thrombin generation assay. CONCLUSION: We present a comprehensive report of a patient with Scott syndrome with a novel frameshift variant in AN06, which is associated with no platelet PS exposure and markedly reduced thrombin generation in whole blood, explaining the significant bleeding phenotype observed.

RESUMEN

There are widespread concerns about a decline in young people's mental health. One promising direction to address this issue involves group memberships and social identity processes. Despite progress, there are several issues in current theory and research including (1) whether the number of groups to which an individual belongs is related to more positive well-being, (2) better understanding the relationship between group memberships and social identification processes and (3) the need for more comprehensive longitudinal methods. The goal of this study was to address these issues using a three-wave longitudinal design (n = 1331) conducted with high-school students. Both the number and importance (an indicator of social identification) of student extracurricular activities (ECA) were assessed as predictors of six well-being outcomes. Importantly, we also assessed whether identification with the school as the context in which the ECAs were situated mediated this association. Results show that, generally, the number of group memberships had no direct effect on well-being, however, there was a consistent mediation via school identification. When considering number and importance of one model (comprising a subsample) importance emerged as the key predictor. Such findings advance understanding of the social identity and well-being relationship and have practical implications.

RESUMEN

Mental illness in adolescents is on the rise, thus it is vital to study factors that can improve youth mental health. The extant theory and research have identified both social (school climate; school identification) and individual (resilience) constructs as protectors of mental health. However, these protective factors remain in silo and require further integration. To address this issue, the present study proposed and investigated an integrative model in which social factors (i.e., school climate, school identification) nurture individual (i.e., resilience) protective factors, which in turn impact adolescent mental health. Using three-wave longitudinal data (2017-2019) from school students (Grades 7-8; N = 1,357), we found evidence supporting the integrated model examining five dimensions of mental health: anxiety, depression, happiness, life satisfaction, and positive affect. Greater Wave 1 school climate predicted greater identification 1 year later, which in turn predicted greater resilience. Furthermore, greater resilience predicted lower depression and anxiety, and greater happiness, life satisfaction, and positive affect 1 year later. These results support efforts to strengthen the school climate and reconceptualize resilience as an outcome of social processes. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

BACKGROUND: Schools are increasingly recognized as key facilitators of child and youth well-being. Much attention has been directed to the school social environment and the areas of school climate or school connectedness/identification. Drawing on the social identity approach and related work, it has been argued that school social identification may be the mechanism or process through which school climate comes to impact individual student functioning (Applied Psychology, 28, 2009, 171). Much of the previous research on social identity and well-being, though, is limited because it is cross-sectional. AIMS, SAMPLE & METHODS: This current study aims to advance understanding of the relationships between school climate, school identification and positive and negative well-being. It adopts a three-wave longitudinal sample of Australian students (N = 6537 wave 3, grades 7-10) and incorporates a range of control variables. Multilevel modelling (MLM) is used to test relationships of interest. RESULTS AND CONCLUSIONS: In line with predictions, school identification was a significant mediator of the relationship between school climate and the well-being dimensions of positive affect and depression (but not anxiety). The substantial theoretical and practical implications of this research are discussed, including the role of the school social environment in helping young people successfully transition to adulthood.

RESUMEN

Previous research has focused on how social identification influences people's adherence to group norms, but has rarely considered how norm adherence might in turn influence how strongly people identify with the group. We proposed a reciprocal relationship between social identification and norm adherence that is shaped by the salience of the social identity in question. Drawing on data from a longitudinal field study of young people attending a mass gathering (N = 661, 1239 unique observations), we used cross-lagged panel modelling across five timepoints to test the reciprocal relationship between social identification with friends and anticipated adherence to perceived drinking norms among friends before (T0), during (T1-T3), and after (T4) the event. Greater social identification at T1 significantly predicted greater norm adherence at T2 which, in turn, predicted greater social identification at T3. These bidirectional effects were only significant during the mass gathering event, when the referent social identity was salient and thus relevant and meaningful in the social context. Findings indicate a complex interplay between social identity and norm adherence that is context dependent and evolves over time. Not only does social identity promote norm adherence but also adherence to those same norms can reinforce a sense of connection to the group.

RESUMEN

Young people worldwide face new challenges as climate change and complex family structures disrupt societies. These challenges impact on youth's subjective well-being, with evidence of decline across many countries. While the burden of negative well-being on productivity is widely examined amongst adults, its cost among youth remains understudied. The current research comprehensively investigates the relationship between youth subjective well-being and standardized academic test scores. We use highly controlled machine learning models on a moderately-sized high-school student sample (N ~ 3400), with a composite subjective well-being index (composed of depression, anxiety and positive affect), to show that students with greater well-being are more likely to have higher academic scores 7-8 months later (on Numeracy: ß* = .033, p = .020). This effect emerges while also accounting for previous test scores and other confounding factors. Further analyses with each well-being measure, suggests that youth who experience greater depression have lower academic achievement (Numeracy: ß* = - .045, p = .013; Reading: ß* = - .033, p = .028). By quantifying the impact of youth well-being, and in particular of lowering depression, this research highlights its importance for the next generation's health and productivity.

RESUMEN

RATIONALE: The effect of COVID-19 lockdowns on mental health is a major concern worldwide. Measuring the impacts, however, is difficult because of a lack of data that tracks and compares outcomes and potential protective social factors before and during lockdowns. OBJECTIVE: We aim to quantify the impact of a second lockdown in 2020 in the Australian city of Melbourne on levels of depression, anxiety, and loneliness, and analyse whether social relations in the neighbourhood may buffer against the worst effects of lockdown. METHODS: We draw on quasi-experimental data from a nationally-representative longitudinal survey conducted in Australia. We use a difference-in-difference approach with a number of control variables to estimate changes in mental health among respondents in Melbourne following the imposition of the lockdown. A measure of perceived neighbourhood social relations is included as an explanatory variable to analyse potential protective effects. RESULTS: Lockdown is estimated to have increased depressive symptoms by approximately 23% and feelings of loneliness by 4%. No effect on anxiety was detected. Levels of neighbourhood social relations were strongly negatively associated with mental health symptoms. A significant interaction between lockdown and neighbourhood social relations suggests that lockdown increased depressive symptoms by 21% for people with average perceived neighbourhood relations, compared with a 9.7% increase for people whose perceived relations is one standard deviation greater than average. CONCLUSION: The results add to evidence of the harsh impacts of the COVID-19 pandemic and associated lockdowns on mental health. Importantly, neighbourhood social relations and social cohesion more broadly may be an important source of social support in response to lockdowns. These findings provide important insights for researchers and policy-makers in how to understand and respond to the mental health impacts of COVID-19.

RESUMEN

The ability to control photoinduced charge transfer within molecules represents a major challenge requiring precise control of the relative positioning and orientation of donor and acceptor groups. Here we show that such photoinduced charge transfer processes within homo- and hetero-rotaxanes can be controlled through organisation of the components of the mechanically interlocked molecules, introducing alternative pathways for electron donation. Specifically, studies of two rotaxanes are described: a homo[3]rotaxane, built from a perylenediimide diimidazolium rod that threads two pillar[5]arene macrocycles, and a hetero[4]rotaxane in which an additional bis(1,5-naphtho)-38-crown-10 (BN38C10) macrocycle encircles the central perylenediimide. The two rotaxanes are characterised by a combination of techniques including electron diffraction crystallography in the case of the hetero[4]rotaxane. Cyclic voltammetry, spectroelectrochemistry, and EPR spectroscopy are employed to establish the behaviour of the redox states of both rotaxanes and these data are used to inform photophysical studies using time-resolved infra-red (TRIR) and transient absorption (TA) spectroscopies. The latter studies illustrate the formation of a symmetry-breaking charge-separated state in the case of the homo[3]rotaxane in which charge transfer between the pillar[5]arene and perylenediimide is observed involving only one of the two macrocyclic components. In the case of the hetero[4]rotaxane charge separation is observed involving only the BN38C10 macrocycle and the perylenediimide leaving the pillar[5]arene components unperturbed.

RESUMEN

Most health models emphasize individual factors in predicting health behavior. However, in the context of COVID-19 where the immediate response to stopping the spread of the virus requires collective efforts and change, other sociopolitical factors need to be considered. Prior research points to health behaviors being impacted by neighborhood and national social relations, social identification, confidence in government and political orientation. This research, though, is generally piecemeal (or specific), tends to be cross-sectional, and is usually not oriented to pandemics. These issues are addressed in the current research. A two-wave study with a representative sample of Australians (N Wave 1 = 3028) gathered during COVID-19 examined sociopolitical factors at the local and national level as predictors of health behaviors one month later. Four models were tested. These encapsulated geographic levels (local or national) and two health behaviors (hand hygiene or physical distance). In the three of the four models, social identification was a significant predictor of health behavior, while controlling for sociodemographic and individual-level measures. There were more mixed results for social relations and confidence in government. There is evidence that to better promote health behaviors sociopolitical factors need to be more prominent in public policy and health behavior models.

RESUMEN

Against the backdrop of evidence that physical activity can protect against depression, there has been growing interest in the mechanisms through which this relationship operates (e.g., biological adaptations), and the factors that might moderate it (e.g., physical activity intensity). However, no attempt has been made to examine whether, or through what mechanisms, depression-related benefits might arise from belonging to groups that engage in physical activity. Across two studies, we addressed these shortcomings by (a) examining whether engaging in physical activity specifically in the context of sport or exercise groups protects against depression and (b) testing two pathways through which benefits might arise: greater physical activity and reduced loneliness. Study 1 (N = 4549) used data from three waves of a population study of older adults residing in England. Sport or exercise group membership predicted fewer depression symptoms four years later. This relationship was underpinned by sport or exercise group members engaging in physical activity more frequently and feeling less lonely. Clinical depression rates were almost twice as high among non-group members than group members. Study 2 (N = 635) included Australian adults who were members of sport and exercise groups, recruited during the enforced suspension of all group-based sport and exercise due to COVID-19 restrictions. The more sport or exercise groups participants had lost physical access to, the more severe their depression symptoms. Clinical depression rates were over twice as high among those who had lost access to >2 groups compared to those who had lost access to <2 groups. The relationship between number of groups lost and depression symptom severity was mediated by greater loneliness, but not by overall physical activity. Overall, findings suggest that belonging to groups that engage in physical activity can protect against depression, and point to the value of initiatives that aim to promote people's engagement in such groups.

RESUMEN

BACKGROUND: Australian health and medical research funders support substantial research efforts, and incentives within grant funding schemes influence researcher behaviour. We aimed to determine to what extent Australian health and medical funders incentivise responsible research practices. METHODS: We conducted an audit of instructions from research grant and fellowship schemes. Eight national research grants and fellowships were purposively sampled to select schemes that awarded the largest amount of funds. The funding scheme instructions were assessed against 9 criteria to determine to what extent they incentivised these responsible research and reporting practices: (1) publicly register study protocols before starting data collection, (2) register analysis protocols before starting data analysis, (3) make study data openly available, (4) make analysis code openly available, (5) make research materials openly available, (6) discourage use of publication metrics, (7) conduct quality research (e.g. adhere to reporting guidelines), (8) collaborate with a statistician, and (9) adhere to other responsible research practices. Each criterion was answered using one of the following responses: "Instructed", "Encouraged", or "No mention". RESULTS: Across the 8 schemes from 5 funders, applicants were instructed or encouraged to address a median of 4 (range 0 to 5) of the 9 criteria. Three criteria received no mention in any scheme (register analysis protocols, make analysis code open, collaborate with a statistician). Importantly, most incentives did not seem strong as applicants were only instructed to register study protocols, discourage use of publication metrics and conduct quality research. Other criteria were encouraged but were not required. CONCLUSIONS: Funders could strengthen the incentives for responsible research practices by requiring grant and fellowship applicants to implement these practices in their proposals. Administering institutions could be required to implement these practices to be eligible for funding. Strongly rewarding researchers for implementing robust research practices could lead to sustained improvements in the quality of health and medical research.

RESUMEN

BACKGROUND: The social identity model of risk taking proposes that people take more risks with ingroup members because they trust them more. While this can be beneficial in some circumstances, in the context of the COVID-19 pandemic it has the potential to undermine an effective public health response if people underestimate the risk of contagion posed by ingroup members, or overestimate the risk of vaccines or treatments developed by outgroup members. METHODS: Three studies (two prospective surveys, one experiment) with community-based adults tested the potential for the social identity model of risk taking to explain risk perception and risk taking in the context of COVID-19. RESULTS: Study 1 was a two-wave study with a pre-COVID baseline, and found that people who identified more strongly as a member of their neighborhood pre-COVID tended to trust their neighbors more, and perceive interacting with them during COVID-19 lockdown to be less risky. Study 2 (N = 2033) replicated these findings in a two-wave nationally representative Australian sample. Study 3 (N = 216) was a pre-registered experiment which found that people indicated greater willingness to take a vaccine, and perceived it to be less risky, when it was developed by an ingroup compared to an outgroup source. We interpret this as evidence that the tendency to trust ingroup members more could be harnessed to enhance the COVID-19 response. CONCLUSIONS: Across all three studies, ingroup members were trusted more and were perceived to pose less health risk. These findings are discussed with a focus on how group processes can be more effectively incorporated into public health policy, both for the current pandemic and for future contagious disease threats.

RESUMEN

BACKGROUND: Blunt chest trauma is associated with significant morbidity, but the long-term functional status for these patients is less well-known. Return to work (RTW) is a benchmark for functional recovery in trauma patients, but minimal data exist regarding RTW following blunt chest trauma. MATERIALS AND METHODS: Patients ≥ 18 y old admitted to a Level 1 trauma center following blunt chest trauma with ≥ 3 rib fractures and length of stay (LOS) ≥ 3 d were included. An electronic survey assessing RTW was administered to patients after discharge. Patients were stratified as having delayed RTW (> 3 mo after discharge) or self-reported worse activities-of-daily-living (ADL) function after injury. Patient demographics, outcomes, and injury characteristics were compared between groups. RESULTS: Median time to RTW was 3 mo (IQR 2,5). Patients with delayed RTW had higher odds of having more rib fractures than those with RTW ≤ 3 mo (median 10 versus 7; OR:1.24, 95%CI:1.04,1.48) as well as a longer LOS (median 13 versus 7 d; OR:1.15, 95% CI:1.04,1.30). Patients with stable ADL after trauma returned to work earlier than those reporting worse ADL (median 2 versus 3.5 mo, P < 0.01). 23.6% of respondents took longer than 5 mo to return to independent functioning, and 50% of respondents' report limitations in daily activities due to physical health after discharge. CONCLUSIONS: The significant proportion of patients with poor physical health and functional status suggests ongoing burden of injury after discharge. Patients with longer LOS and greater number of rib fractures may be at highest risk for delayed RTW after injury.

RESUMEN

INTRODUCTION: Preinjury alcohol use and older age have independently been associated with poor outcomes. This study examined whether higher levels of blood alcohol concentration (BAC) correlated with an increased likelihood of poor outcomes in older trauma patients. METHODS: This was a retrospective cohort study of injured patients ≥65 years with BAC testing presenting to a Level 1 trauma center between 2015 and 2018. Patients were stratified by BAC at 4 thresholds of intoxication: BAC ≧10 mg/dL, BAC ≧80 mg/dL, BAC ≧150 mg/dL, and BAC ≧200 mg/dL. Propensity score matching using inverse probability of treatment weighting was used to estimate outcomes. Logistic and Poisson regression models were performed for each threshold of the BAC level with the matched cohort to assess clinical outcomes. RESULTS: Of all older patients (n = 3112), 32.5% (n = 1012) had BAC testing. In the matched cohort of 883 patients (76.7 ± 8.2 years; 48.1% female), 111 (12.5%) had BAC ≧10 mg/dL, 83 (74.8%) had BAC ≧80 mg/dL, 60 (54.1%) had BAC ≧150 mg/dL, and 37 (33.3%) had BAC ≧200 mg/dL. Falls (60.5%) and motor vehicle crashes (28.9%) were the most common mechanisms of injury. Median (IQR) of Injury Severity Score (ISS) was 5 (1-10). The risk of severe injury (ISS ≧15) was similar between alcohol-positive and alcohol-negative patients (9.9% vs 15.0%, P = .151). BAC ≧10 g/dL was not associated with length of stay, intensive care unit admission, or in-hospital complication, nor was any of the other 3 analyzed BAC thresholds. CONCLUSION: Overall, any detectable BAC along and increasing thresholds of BAC was not associated with poor in-hospital outcomes of older patients after trauma. Alcohol screening was low in this population, and intoxication may bias injury assessment, leading to mistriage of older trauma patients.

RESUMEN

The current study investigates the theory of planned behavior with important additional predictors from the social identity approach. The study explores whether social identity might function as a driver of the theory of planned behavior and help explain how abstract group processes might impact student binge drinking behavior. Adopting a controlled statistical analysis, the hypothesized model expands the theory of planned behavior's current conceptualization of group norms and considers how the behavioral content of a specific group, with group identification, impacts binge drinking behavior (N = 551 university students). A path analysis that simultaneously mapped all the hypothesized relationships supported a reconceptualization of social identity as a predictor within the theory of planned behavior. The interaction between group identification and the importance of drinking to the group's identity significantly predicted an individual's attitudes towards binge drinking and perceived social binge drinking norms (subjective, descriptive and injunctive), which in turn predicted intentions to binge drink. Intentions to binge drink predicted self-reported binge drinking behavior two weeks later, above and beyond relevant covariates. The implications of these findings are discussed, with recommendations for future research.

RESUMEN

Rasch/Guttman Scenario (RGS) scales produce scores that map onto interpretable descriptions of individuals at different levels of hierarchically progressive constructs. The unique scenario item format provides actionable and rich content-relevant feedback about (a) respondent status, (b) intervention design, and (c) longitudinal change on a construct. This article presents a seven-step methodological framework for the development of RGS scales. We also reflect on plausible challenges that may arise in the applications of RGS scale development and propose future research directions for the methodology.

RESUMEN

Poor recognition of other-race faces is ubiquitous around the world. We resolve a longstanding contradiction in the literature concerning whether interracial social contact improves the other-race effect. For the first time, we measure the age at which contact was experienced. Taking advantage of unusual demographics allowing dissociation of childhood from adult contact, results show sufficient childhood contact eliminated poor other-race recognition altogether (confirming inter-country adoption studies). Critically, however, the developmental window for easy acquisition of other-race faces closed by approximately 12 years of age and social contact as an adult - even over several years and involving many other-race friends - produced no improvement. Theoretically, this pattern of developmental change in plasticity mirrors that found in language, suggesting a shared origin grounded in the functional importance of both skills to social communication. Practically, results imply that, where parents wish to ensure their offspring develop the perceptual skills needed to recognise other-race people easily, childhood experience should be encouraged: just as an English-speaking person who moves to France as a child (but not an adult) can easily become a native speaker of French, we can easily become "native recognisers" of other-race faces via natural social exposure obtained in childhood, but not later.
