ABSTRACT

Pundits have speculated that the spread of conspiracies and misinformation (termed "misbeliefs") is leading to a resurgence of right-wing, reactionary movements. However, the current empirical picture regarding the relationship between misbeliefs and collective action is mixed. We help clarify these associations by using two waves of data collected during the COVID-19 Pandemic (in Australia, N = 519, and the United States, N = 510) and democratic elections (in New Zealand N = 603, and the United States N = 609) to examine the effects of misbeliefs on support for reactionary movements (e.g., anti-lockdown protests, Study 1; anti-election protests, Study 2). Results reveal that within-person changes in misbeliefs correlate positively with support for reactionary collective action both directly (Studies 1-2) and indirectly by shaping the legitimacy of the authority (Study 1b). The relationship between misbelief and legitimacy is, however, conditioned by the stance of the authority in question: the association is positive when authorities endorse misbeliefs (Study 1a) and negative when they do not (Study 1b). Thus, the relationship between conspiracy beliefs and action hinges upon the alignment of the content of the conspiracy and the goals of the collective action.

ABSTRACT

Carotenoid pigments provide some of the most common exclusively biogenic markers on Earth, and these organic pigments may be present in extraterrestrial life. Raman spectroscopy can be used to identify carotenoids quickly and accurately through the inelastic scattering of laser light. In this study, we show that Raman spectra of organic matter found in hot spring bacterial assemblages exhibit "spectral overprinting" of the carotenoid spectrum by the carbon spectrum as the organic matter progressively breaks down. Here, we present how, with increasing thermal maturity, the relative intensity of the carotenoid spectrum increases, and as maturity increases a low-intensity carbon spectrum forms in the same region as the carotenoid spectrum. This carbon spectrum increases in intensity as the thermal maturity increases further, progressively obscuring the carotenoid spectrum until only the carbon spectrum can be observed. This means key carotenoid biogenic signatures in hot spring deposits may be hidden within carbon spectra. A detailed study of the transition from carotenoid to carbon, Raman spectra may help develop deconvolution processes that assist in positively identifying biogenic carbon over abiogenic carbon. Our results are relevant for the data analysis from the Raman spectroscopy instruments on the Perseverance (National Aeronautics and Space Administration [NASA]) and Rosalind Franklin (European Space Agency [ESA]) rovers.

ABSTRACT

BACKGROUND: This study examined student and caregiver preference for school communication and explored the feasibility and acceptability of a digital tool to assist with communication about school meal program between schools and families. METHODS: The study used qualitative methodology through youth focus groups and caregiver semi-structured phone interviews. The study was conducted in 4 high schools in a large, urban city. The phenomenon of interest included the exploration of preferences regarding communication around school meal programs and feasibility and acceptability of a digital tool for communication and promoting the ordering of healthful foods in the school environment. Interviews were transcribed, coded, and analyzed through NVivo qualitative software using thematic analysis approach to examine themes. RESULTS: Forty-seven students (ages 14-21, grades 9-12) participated in 7 focus groups and 24 caregivers participated in semi-structured phone interviews. Three themes emerged around (1) communication preferences, (2) accessibility, and (3) extrinsic motivational factors for engagement in healthy eating behaviors. CONCLUSION: Results indicated that communication methods could potentially influence motivation and engagement in youth school meal participation.

ABSTRACT

Food insecurity occurs when a household lacks consistent access to food and is more prevalent in ethnic and racial minority populations. While there has been a proliferation of research linking food insecurity to obesity, these findings are mixed. It may be helpful to consider some additional geographic factors that may be associated with both factors including socioeconomic status and grocery store density. The purpose of the current study aimed to examine spatial relationships between food insecurity and SES/store density and BMI and SES/store density in a diverse sample of adolescents and young adults across two studies in a large, urban city. GIS analysis revealed that participants with the highest food insecurity tend to live in the zip codes with the lowest median income. There did not appear to be clear a relationship between food insecurity and store density. Participants with the highest BMI tend to live in zip codes with lower median income and participants with higher BMI tended to live in the south and west sides of Chicago, which have a relatively lower concentration of grocery stores in the city. Our findings may help to inform future interventions and policy approaches to addressing both obesity and food insecurity in areas of higher prevalence.

ABSTRACT

Building local food systems through a food sovereignty lens, harnessing the right of people to control their own food systems, may enhance healthy food access and increase the consumption of fruits and vegetables in local communities. While research to date has described the outcomes of various multilevel, multicomponent food systems interventions, no known literature reviews to date have systematically examined food system interventions and dietary and health outcomes through the context of a food sovereignty lens. Utilization of a food sovereignty framework allows for the incorporation of key food systems and community-based concepts in the food environment literature. The purpose of this systematic review was to describe and summarize the efficacy of community-based local food system interventions, using the food sovereignty framework, for both pediatric and adult populations and their impact on health behaviors and physiological outcomes. We searched for peer-reviewed articles using Scopus, PubMed, PsychInfo and CINAHL databases and identified 11 articles that met the inclusion criteria for this study. Seven studies found that food systems interventions had a significant positive effect on improving health outcomes, three had null findings and one had null or negative results. Two studies utilized a community-based participatory approach. The most successful interventions involved community-based engagement involving multiple aspects of the food system and involving both children and adults for maximum impact. Our results inform how community-based food systems interventions can be guided by food sovereignty principles to improve health outcomes, such as body weight and fruit and vegetable intake, for both pediatric and adult populations.

ABSTRACT

Refugees can experience elevated levels of psychological distress upon resettlement, although disparate outcomes over time are expected. The current study modeled trajectories of changes in distress over a 5-year period among resettled refugees and sought to explicate post-settlement factors that influence distress over time. A large-scale sample of refugees resettled in Australia (2,399) was tracked over a 5-year period, completing measures of psychological distress at each wave and initial risk and protective factors immediately after resettlement. A latent class growth analysis conducted on distress found four unique classes characterized by (1) resilient levels of distress, (2) consistent clinical distress, (3) recovering levels of distress, and (4) deteriorating distress. Lower perceived discrimination and greater positive context of reception predicted membership to the resilient group and differentiated the recovering and deteriorating groups. Further, lower ingroup social support predicted membership to the clinically distressed group relative to all others. We conclude by echoing calls to strengthen community support for refugees and promote ingroup ties, particularly among those who are the most vulnerable.

ABSTRACT

Australian adolescents living in regional communities are significantly more likely to perform worse at school, relative to those in metropolitan communities. These disparities are partially due to the development of lower educational expectations among regional adolescents. In the current study, we tested whether the differences in educational expectations across communities were reduced when adolescents engage in extracurricular activities, and any subsequent downstream effects on academic outcomes. The current study used a subsample of 1,477 adolescents recruited as part of the Longitudinal Study of Australian Children who have graduated from high school. Using a random-intercept cross-lagged panel model, we found that residing in a regional community at the start of secondary education predicted worse academic performance when graduating 6 years later. This association was partially mediated by lower educational expectations and school functioning, measured biennially. However, the significant difference between adolescents in metropolitan and regional communities dissipated when participants engaged in three or more types of extracurricular activities. These results highlight that increasing access and support to participate in extracurricular activities in regional communities may contribute to reducing inequities in educational outcomes.

ABSTRACT

BACKGROUND: The school food environment is a critically important area to target the health of millions of students, especially those experiencing food insecurity. However, both students and caregivers have noted significant barriers to participation in the school meal program, including taste, lunchroom experience, and limited availability of fresh, healthy foods. There is a lack of qualitative research which considers both caregiver and adolescent perspectives, particularly among youth of color. METHODS: Forty-seven students (77% Black) and 24 caregivers across 4 midwestern high schools participated in focus groups and key informant interviews assessing barriers and facilitators to school meal participation. We conducted thematic analysis of the data using matrix intersection queries and reviewing frequencies of relevant nodes to identify themes. RESULTS: Themes about the importance of freshness and quality of the foods served in the lunchroom emerged from both students and caregivers. CONCLUSIONS: Future research may explore differences in meal participation depending on types of vender, farm to school program status, and other local variations in public schools and determine whether they increase participation, reduce food insecurity, and increase diet quality.

ABSTRACT

Using the frameworks of Latino Critical Race Theory (LatCrit) and an integrative model of developmental competencies, this study examined the roles of cultural mistrust toward education and natural mentoring relationship quality in the academic outcomes of Latinx adolescents. Participants were 294 Latinx students (52.9% female; mean age 15 years in 9th grade; 21% first-generation, 63% second-generation, and 6% third-generation immigrants) who completed surveys in 9th and 10th grades. The negative effect of cultural mistrust on educational aspirations was greater for students who had poorer quality mentoring relationships. This study addresses gaps in the literature related to cultural mistrust as a coping strategy and discusses the ways in which mentors can serve a protective role.

ABSTRACT

Increasing substance use and decreasing well-being are typical in adolescence, yet how social contexts shape disparate development during this time is less well-understood. A latent growth class analysis was conducted that identified groups of early (N = 706; Agem = 12.20) and middle (N = 666; Agem = 14.38) adolescents distinguished by rates of substance use and well-being over three years. In both cohorts, the largest group reported low substance use and high well-being, with a smaller group exhibiting maladaptive trajectories for both substance use and well-being. Two additional groups were identified during middle adolescence characterized by either low well-being or high substance use. Family connectedness was a protective factor, while high peer connectedness was a risk factor for substance-use groups and low peer connectedness for languishing.

ABSTRACT

This study aimed to test a longitudinal model of trust in adults and psychological well-being among Latinx adolescents, a population that has received little attention in the trust literature. The participants were urban, low-income Latinx (N = 294) students at two urban, Midwestern high schools who indicated they had at least one natural mentor in 9th grade. Participants completed surveys at two-time points, in 9th and 10th grade, and responded to measures of their feelings toward adults, quality of their natural mentoring relationships, self-esteem, intrinsic academic motivation, and coping self-efficacy. More trust in adults was indirectly, but not directly, associated with higher coping self-efficacy via higher mentoring relational quality and self-esteem. Positive expectations of adults may open Latinx youth to closeness in natural mentoring relationships and positive self-perceptions, which may, in turn, bolster coping ability.

ABSTRACT

Four studies investigated the link between cross-race friendships and attraction. In Study 1, White Australian participants (N = 240) who reported friendships with racial outgroup members were more likely to report attraction to the members of the racial group their friends belonged to. Studies 2a (N = 300 White American participants) and 2b (N = 303 White British participants) showed that experiences of cross-race non-verbal intimacy, perceived cross-race reciprocity in attraction, positive perceived ingroup norms about dating cross-racially, and warmth toward the racial outgroup were particularly important in explaining the friendship-attraction link in majority samples. Study 3 (N = 292 Black British participants) showed that in addition to the mediators above, self-disclosure was key to explaining the friendship-attraction link for racial minority group members. These findings extend the contact literature by exploring the specificity and mediators of the link between contact and attraction in the context of race relations.

ABSTRACT

Parents/caregivers are consistently described as integral targets given their influential role in supporting and managing behaviors such as diet and physical activity. Identifying effective obesity prevention interventions to enhance and sustain parent participation is needed. Digital obesity prevention interventions are a promising strategy to improve parent/caregiver participation. Digital health interventions demonstrate acceptable participation and retention among parents/caregivers. However, our understanding of digital obesity prevention interventions targeting Black American and Latinx parents/caregivers is limited. This systematic review aims to identify Black American and Latinx parents'/caregivers' level of participation in digital obesity prevention and treatment interventions and determine the relationship between parent/caregiver participation and behavioral and weight status outcomes. This review adheres to PRISMA guidelines and is registered in PROSPERO. Eligibility criteria include: intervention delivered by digital technology, targeted Black American and Latinx parents/caregivers of young children (2-12 years), reported parent/caregiver participation outcomes, targeted diet or physical activity behaviors, and randomized controlled trial study design. Searches were conducted in September 2020 in ERIC, PsychInfo, PubMed, and Web of Science. Initial searches returned 499 results. Four reviewers screened records against eligibility criteria and 12 studies met inclusion criteria. Across all studies, parent/caregiver participation ranged from low to high. Only half of the included studies reported significant improvements in behavioral or weight status outcomes for parents/caregivers and/or children. Of these studies, three reported high parental/caregiver participation rates, and three reported high satisfaction rates. These findings suggest that participation and satisfaction may impact behavior change and weight status. The small number of studies indicates that additional research is needed to determine whether engagement or other factors predict responsiveness to the digital health intervention. Our results lay the groundwork for developing and testing future digital health interventions with the explicit goal of parental/caregiver participation and considers the need to expand our digital health intervention research methodologies to address obesity inequities among diverse families better.

ABSTRACT

Laboratory-based aversive conditioning studies have reliably induced fear toward an image of an outgroup member by pairing the image with a fear-inducing, aversive stimulus. However, laboratory-based studies have been criticized for being simplistic in comparison to the complexities of the real world. The current study is the first to apply an aversive conditioning framework to explain the formation of intergroup fear and subsequent anxiety toward, and avoidance of, the outgroup outside the laboratory. Two samples recalled details of their first negative encounter with an African American (N = 554) or Muslim (N = 613) individual, respectively. Congruent with learning theory, participants who reported an unpleasant event with an outgroup member reported more fear during the encounter than did those who did not report experiencing an unpleasant event. Additionally, the intensity of unpleasantness during the first encounter indirectly predicted outgroup avoidance, via retrospectively recalled fear and current levels of intergroup anxiety.

ABSTRACT

INTRODUCTION: Youth with refugee backgrounds experience social and socioeconomic difficulties that arise following resettlement. Research has found that sport participation generally provides youth with a protective milieu that is especially beneficial for the most disadvantaged youth. Accordingly, the current study examines whether sport participation is related to positive psychosocial outcomes for resettled adolescent refugees, and if these effects are greater for those living in socioeconomically disadvantaged communities. METHOD: Data were from a large, nationally representative cohort of refugees recently resettled in Australia (Building New Life in Australia study, BNLA). Self-reported social and emotional well-being was collected from 415 youth who entered the country as refugees (Mage = 14.04, SD = 1.99) at three years post settlement were used. RESULTS: A moderated regression analysis indicated that refugee youth living in socioeconomically disadvantaged neighborhoods who participated in sports reported significantly better outcomes compared to those refugee youth in economically similar neighborhoods who did not participate in sport. In contrast, refugee youth residing in more socioeconomically advantaged communities had better developmental outcomes, regardless of sport participation. CONCLUSIONS: Sport participation is a protective factor for youth with refugee backgrounds. Community socioeconomic disadvantage moderates this relationship, whereby stronger effects were observed for adolescents in more disadvantaged communities. Protecting the most disadvantaged in our society is a human rights imperative, and the current study indicates that sport participation could contribute to these efforts among resettled refugee populations.

ABSTRACT

RATIONALE: Humanitarian crises and ongoing conflicts around the world have created large populations of refugees who require permanent resettlement. The often-difficult pathway to resettlement for refugees places them at elevated risks for ongoing psychological and financial problems, creating an imperative to investigate the longterm outcomes for refugees as they resettle. OBJECTIVE: The current study explores how adversities before and after resettlement impact the psychological distress and experiences of financial hardship over the course of four years postsettlement for a large group of resettled refugees in Australia. METHOD: Data from the first four waves of the Building New Life in Australia (BNLA) study (N = 1509) were used. Recently resettled refugees completed measures of pre-migration trauma and post-settlement difficulties at the initial data collection wave as well as measures of psychological distress and financial hardship across all four waves. RESULTS: Through a random intercept cross-lagged panel model, a time-sensitive bi-directional relationship between psychological distress and financial hardship was found. Additionally, early post-settlement difficulties were indirectly related to both psychological distress and financial hardship over time. In contrast, pre-migration trauma did not significantly predict later outcomes. CONCLUSIONS: These results illustrate that trauma focused interventions may be insufficient on their own for assisting resettled refugees in this context. As such, our findings highlight the crucial importance of early identification and responsiveness to the variety of initial difficulties, such as language and housing problems, that may be experienced by resettled refugees to mitigate against subsequent psychological and financial difficulties in the long-term.

ABSTRACT

Social networking sites (SNSs) are social platforms that facilitate communication. For adolescents, peers play a crucial role in constructing the self online through displays of group norms on SNSs. The current study investigated the role of online social identity (OSI) in the relationship between adolescent exposure to alcohol-related content posted by peers on SNSs and alcohol use. In a sample (N = 929) of Australian adolescents (Age M = 17.25, SD = 0.31) higher levels of exposure to alcohol-related content on SNSs was associated with higher levels of alcohol use. Importantly, the association was stronger when the participants reported higher OSI particularly when also reporting low or moderate amount of time spent on SNS. The findings can be explained by social identity literature that demonstrates individuals align their behaviors with other members of their social group to demonstrate, enact, and maintain social identity. The results of this study reflect the importance of considering the construction of the "self" through online and offline constructs.
