RESUMEN
The purpose of this study was to develop a measure of racial-ethnic-cultural (REC) belonging for Black, Indigenous, and other people of color (BIPOC). The iBelong Scale was designed to assess the multidimensional components of REC belonging across diverse BIPOC groups. The scale was constructed based on a grounded conceptual framework of REC belonging, and the initial pool of items received feedback from community members and content experts. Validation of the iBelong Scale comprised data from 808 BIPOC participants collected across three interrelated studies for the purposes of initial validation, construct validity, and test-retest reliability. In Study 1, an exploratory factor analysis yielded a 25-item scale with five factors: (a) Home, (b) Connection, (c) Authenticity, (d) REC Thriving, and (e) Self-Definition. Results from Study 2's confirmatory factor analysis indicated that the five-factor model was an acceptable fit of the data and the best fit among competing models. Measurement invariance was assessed, and results indicated that the iBelong Scale measures REC belonging similarly across differing BIPOC groups. The iBelong Scale was related to a range of measures in theoretically expected ways, including positive associations with general belonging, racial/ethnic identity, and general well-being, and negative associations with loneliness and REC nonbelonging. Findings from Study 3 indicated the test-retest reliability of the iBelong Scale over a 2-week period. Limitations of the studies and implications for research and practice are discussed.

Suicide is a leading cause of death among Black emerging adults. The concurrent effect of the COVID-19 pandemic and racial discrimination were projected to exacerbate suicide vulnerability for Black Americans. The purpose of the present study was to utilize a risk-resilience model to examine the effects of racial discrimination and COVID-related stress on suicide risk for Black emerging adults, as well as the moderating effect of three central components of radical healing: critical consciousness, resilience, and cultural authenticity. Study participants included 521 Black emerging adults between the ages of 18 and 29 (51.6% male; Mage = 24.6, SD = 2.6) who completed measures evaluating symptoms of racial discrimination, COVID-related stress, suicide risk, and psychological well-being. After controlling for age, gender, socioeconomic status, and general stress, structural equation modeling analyses revealed unique and interactive effects of racial discrimination, COVID-related stress, and culturally relevant protective factors on suicide risk for Black emerging adults. These findings provide preliminary insight into novel risk and protective factors that influence suicide risk for Black emerging adults. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
RESUMEN
Human activities and climate change threaten coldwater organisms in freshwater ecosystems by causing rivers and streams to warm, increasing the intensity and frequency of warm temperature events, and reducing thermal heterogeneity. Cold-water refuges are discrete patches of relatively cool water that are used by coldwater organisms for thermal relief and short-term survival. Globally, cohesive management approaches are needed that consider interlinked physical, biological, and social factors of cold-water refuges. We review current understanding of cold-water refuges, identify gaps between science and management, and evaluate policies aimed at protecting thermally sensitive species. Existing policies include designating cold-water habitats, restricting fishing during warm periods, and implementing threshold temperature standards or guidelines. However, these policies are rare and uncoordinated across spatial scales and often do not consider input from Indigenous peoples. We propose that cold-water refuges be managed as distinct operational landscape units, which provide a social and ecological context that is relevant at the watershed scale. These operational landscape units provide the foundation for an integrated framework that links science and management by (1) mapping and characterizing cold-water refuges to prioritize management and conservation actions, (2) leveraging existing and new policies, (3) improving coordination across jurisdictions, and (4) implementing adaptive management practices across scales. Our findings show that while there are many opportunities for scientific advancement, the current state of the sciences is sufficient to inform policy and management. Our proposed framework provides a path forward for managing and protecting cold-water refuges using existing and new policies to protect coldwater organisms in the face of global change.

One critical role counseling psychologists can play in dismantling anti-Blackness and eradicating systemic racism is to build on the field's strength in understanding individual-level processes (i.e., systems are created and maintained by individual actors). Drawing on antiracism scholarship, we aimed to better understand how colorblind racial ideology (CBRI), or the denial and minimization of race and racism, may serve as a barrier to engaging in antiracist praxis. Specifically, we conducted a meta-analysis to determine if color evasion (ignoring race) and power evasion (denying structural racism) CBRI were differentially associated with anti-Blackness and processes linked to antiracism. Findings based on 375 effects drawn from 83 studies with more than 25,000 individuals suggest different effects based on CBRI type. As hypothesized, we found that power evasion CBRI was related to increased endorsement of anti-Black prejudice (r = .33) and legitimizing ideologies (r = .24), and negatively associated with a range of other variables associated with antiracism, including social justice behaviors (r = -.31), multicultural practice competencies (r = -.16), diversity openness (r = -.28), and racial/ethnocultural empathy (r = -.35). Consistent with theory, color evasion CBRI was related to increased diversity openness (r = .12). We discuss limitations of our study, as well as outline future directions for research and practice to focus on the role of CBRI in sustaining and perpetuating anti-Blackness and systemic racism. Thus, this meta-analysis has implications for pushing the field of counseling psychology to build the bridge between individual ideologies and creating structural change.

The negative impact of racism on Black, Indigenous, and People of Color's (BIPOC's) mental and physical health is well-documented. Research supports the critical role of personal hope as a buffer against despair and adverse health outcomes among BIPOC. However, there is a dearth of empirical research exploring the experiences of BIPOC's sense of collective hope. This study aimed to help fill this gap in the literature by extending Mosley et al.'s (2020) multidimensional psychological framework of radical hope via a qualitative study. Radical hope includes a collective motivation of hope for BIPOC communities to work toward a more egalitarian future. In this study, focus groups and interviews were conducted with 29 BIPOC adults, with and without mental health training, to explore participants' perceptions of radical hope. Seven interrelated themes were identified. Two core components and four themes aligned with and extended Mosley et al.'s (2020) framework: Collective Orientation, Faith and Agency, Resisting Racism, Embracing Racial Pride, Envisioning Possibilities, and Meaning Making and Purpose. We also identified a new theme, Valuing Self. Implications for clinical practice and research are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

OBJECTIVES: The purpose of this study was to develop and provide initial psychometric support for the Racially Biased Reasoning Scale-Police (RBias-Police). The vignette-based RBias-Police is designed to capture rigid racially biased beliefs. The items focus on police interactions with people of color as this is a particularly emotional-laden issue in the United States that signifies deeper racial and social intolerance. METHOD: Data from a combined sample of 1,156 participants were collected through Mechanical Turk for two interrelated studies. In the first study, we used matrix sampling and exploratory structural equation modeling to explore the factor structure of RBias-Police. In the second study, we conducted confirmatory factor analysis and explored the construct validity with theoretically relevant concepts. RESULTS: In Study 1, we found that 10 items with three factors solution captured the data across each of the six vignettes: (a) Minimization of Racism, (b) Target Apathy, and (c) Target Blaming. In Study 2, findings from confirmatory factor analysis supported that the three-factor model was a good fit to the data. The RBias-Police factors were positively related to color-blind racial ideology and the general belief in a just world in theoretically expected ways. CONCLUSIONS: Across two studies, our findings provide initial psychometric support for the RBias-Police; this new measure captures both affective and cognitive dimensions of biased reasoning.

Objectives: Recently, research has focused both on the influence of institutional racism and how the Global Majority, which includes Black, Indigenous and People of Color, heal from processes related to racial and other forms of oppression. We propose a framework of healing research methodologies that is situated within emerging diversity science trends. This framework specifically is designed to apply diversity science principles to develop research that is culturally relevant and can help explain intragroup processes related to healing from institutional racism. Methods: Drawing from the diversity science, liberation and critical research methodologies, and psychological healing practices literature, we propose a healing research methodologies framework. Results: The healing research methodologies framework consists of six critical components: maintains social justice ethics, adopts liberation methodologies, implements healing methods, embraces interdisciplinary approaches, catalyzes action, and promotes community accessibility. Conclusions: We offer recommendations to guide future diversity science healing research. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Studies commonly examine resilience as an outcome by way of measuring the degree to which protective factors maintain individuals' well-being despite the presence of significant risk. In this study, we developed a model of community resilience that centered the voices of Black youth. Using data collected as part of a 3-year, youth participatory action research project, we developed a model that focuses on what 11 Black youth perceive and believe contributes to community resilience through their investigation of problems and solutions related to community gun violence. Findings from a constructivist grounded theory analysis of multiple data sources (e.g., field notes, transcribed group discussions, youth photovoice activities) revealed our developing model of community resilience: Power through Black Community and Unity. Specifically, Power through Black Community and Unity was a core category that reflected the importance of care, support, and safety as strengths in the community's current response and resilience to gun violence, and future aspects the community could develop to increase community resilience to gun violence. This core category emerged in three subsequent ways: Collective Care, "Seeing Beyond the Bad," and Supportive Teen Spaces. This study illustrates potential pathways that youth service agencies and community practitioners can consider enhancing in their programming to promote resilience in their communities.

Preliminary evidence suggests that people and scholars of African and/or Latin American and Caribbean origin are often under-represented in mainstream attachment scholarship. In this commentary, we highlight the difficulty of conducting attachment theory research outside of the United States, particularly in Latin American countries. We reflect on the contributions by the authors of this special issue . We also identify (a) ways in which to center the experiences of Black and Brown people and scholars to push the field toward antiracism, and (b) the challenges of attachment theory and research in becoming anti-racist by considering the structural nature of racism.

Population viability analysis (PVA) is a powerful conservation tool, but it remains impractical for many species, particularly species with multiple, broadly distributed populations for which collecting suitable data can be challenging. A recently developed method of multiple-population viability analysis (MPVA), however, addresses many limitations of traditional PVA. We built on previous development of MPVA for Lahontan cutthroat trout (LCT) (Oncorhynchus clarkii henshawi), a species listed under the U.S. Endangered Species Act, that is distributed broadly across habitat fragments in the Great Basin (U.S.A.). We simulated potential management scenarios and assessed their effects on population sizes and extinction risks in 211 streams, where LCT exist or may be reintroduced. Conservation populations (those managed for recovery) tended to have lower extinction risks than nonconservation populations (mean = 19.8% vs. 52.7%), but not always. Active management or reprioritization may be warranted in some cases. Eliminating non-native trout had a strong positive effect on overall carrying capacities for LCT populations but often did not translate into lower extinction risks unless simulations also reduced associated stochasticity (to the mean for populations without non-native trout). Sixty fish or 5-10 fish/km was the minimum reintroduction number and density, respectively, that provided near-maximum reintroduction success. This modeling framework provided crucial insights and empirical justification for conservation planning and specific adaptive management actions for this threatened species. More broadly, MPVA is applicable to a wide range of species exhibiting geographic rarity and limited availability of abundance data and greatly extends the potential use of empirical PVA for conservation assessment and planning.
Aplicación de un Análisis de Viabilidad Multi-Poblacional para Evaluar Alternativas de Recuperación de Especies Resumen El análisis de viabilidad poblacional (AVP) es una herramienta poderosa de conservación, que desafortunadamente sigue siendo impráctica para muchas especies, en particular para aquellas con poblaciones múltiples distribuidas ampliamente, para las cuales puede ser un reto la recolección de datos apropiados. Sin embargo, un método recientemente desarrollado de análisis de viabilidad multi-poblacional (AVMP) aborda muchas de las limitaciones de los AVP tradicionales. Partimos del desarrollo previo de un AVMP para la trucha degollada lahontana (LCT, en inglés) (Oncorhynchus clarkii henshawi), una especie enlistada bajo el Acta de Especies en Peligro de los Estados Unidos, la cual está distribuida ampliamente a lo largo de los fragmentos de hábitat que se encuentran en la Gran Cuenca (E.U.A.). Simulamos los escenarios potenciales de manejo y evaluamos sus efectos sobre el tamaño de las poblaciones y los riesgos de extinción en 211 arroyos en donde existe la LCT o en donde podría ser reintroducida. Las poblaciones de conservación (aquellas manejadas para su recuperación) tuvieron una tendencia hacia un riesgo de extinción más bajo que las poblaciones sin conservación (media = 19.8% vs. 52.7%), pero no en todos los casos. El manejo activo o la repriorización podrían ser justificadas en algunos casos. La eliminación de las truchas no nativas tuvo un fuerte efecto positivo generalizado sobre las capacidades de carga de las poblaciones de LCT, aunque frecuentemente esto no se transformó en un riesgo de extinción más bajo a menos que las simulaciones también redujeran la estocasticidad asociada (para la media de las poblaciones sin truchas no nativas). Para proporcionar un éxito de reintroducción cercano al máximo, el número mínimo de reintroducción debió ser de 60 peces o una densidad de 5-10 peces/km. Este marco de trabajo para el modelo proporcionó una percepción muy importante y una justificación empírica para la planeación de la conservación y para las acciones de manejo adaptativo para esta especie amenazada. En términos más generales, el AVMP puede aplicarse a una gama amplia de especies que exhiban una rareza geográfica y una disponibilidad limitada de datos de abundancia, además de que expande enormemente el uso potencial de AVP empíricos para la evaluación y planeación de la conservación.

This article reviews the trajectory of our research program on selective attention, which has moved from basic research on the neural processes underlying selective attention to translational studies using selective attention as a neurobiological target for evidence-based interventions. We use this background to present a promising preliminary investigation of how genetic and experiential factors interact during development (i.e., gene × intervention interactions). Our findings provide evidence on how exposure to a family-based training can modify the associations between genotype (5-HTTLPR) and the neural mechanisms of selective attention in preschool children from lower socioeconomic status backgrounds.

Discovering genetic markers associated with phenotypic or ecological characteristics can improve our understanding of adaptation and guide conservation of key evolutionary traits. The Lahontan cutthroat trout (Oncorhynchus clarkii henshawi) of the northern Great Basin Desert, USA, demonstrated exceptional tolerance to high temperatures in the desert lakes where it resided historically. This trait is central to a conservation hatchery effort to protect the genetic legacy of the nearly extinct lake ecotype. We genotyped full-sibling families from this conservation broodstock and samples from the only two remaining, thermally distinct, native lake populations at 4,644 new single nucleotide polymorphisms (SNPs). Family-based genome-wide association testing of the broodstock identified nine and 26 SNPs associated with thermal tolerance (p < 0.05 and p < 0.1), measured in a previous thermal challenge experiment. Genes near the associated SNPs had complex functions related to immunity, growth, metabolism and ion homeostasis. Principal component analysis using the thermotolerance-related SNPs showed unexpected divergence between the conservation broodstock and the native lake populations at these loci. FST outlier tests on the native lake populations identified 18 loci shared between two or more of the tests, with two SNPs identified by all three tests (p < 0.01); none overlapped with loci identified by association testing in the broodstock. A recent history of isolation and the complex genetic and demographic backgrounds of Lahontan cutthroat trout probably limited our ability to find shared thermal tolerance loci. Our study extends the still relatively rare application of genomic tools testing for markers associated with important phenotypic or environmental characteristics in species of conservation concern.

Population viability analysis (PVA) uses concepts from theoretical ecology to provide a powerful tool for quantitative estimates of population dynamics and extinction risks. However, conventional statistical PVA requires long-term data from every population of interest, whereas many species of concern exist in multiple isolated populations that are only monitored occasionally. We present a hierarchical multi-population viability analysis model that increases inference power from sparse data by sharing information among populations to assess extinction risks while accounting for incomplete detection and sampling biases with explicit observation and sampling sub-models. We present a case study in which we customized this model for historical population monitoring data (1985-2015) from federally threatened Lahontan cutthroat trout populations in the Great Basin, USA. Data were counts of fish captured during backpack electrofishing surveys from locations associated with 155 isolated populations. Some surveys (25%) included multi-pass removal sampling, which provided valuable information about capture efficiency. GIS and remote sensing were used to estimate August stream temperatures, peak flows, and riparian vegetation condition in each population each year. Field data were used to derive an annual index of nonnative trout densities. Results indicated that population growth rates were higher in colder streams and that nonnative trout reduced carrying capacities of native trout. Extinction risks increased with more environmental stochasticity and were also related to population extent, water temperatures, and nonnative densities. We developed a graphical user interface to interact with the fitted model results and to simulate future habitat scenarios and management actions to assess their influence on extinction risks in each population. Hierarchical multi-population viability analysis bridges the gap between site-level field observations and population-level processes, making effective use of existing datasets to support management decisions with robust estimates of population dynamics, extinction risks, and uncertainties.

The relationship between early adversity and outcomes across the lifespan is apparent in a striking range of measures. Evidence suggests that many of these outcomes can be traced to the impacts of early adversity on multiple and integrated biological systems mediated by the brain. In this review, we integrate empirical and theoretical advances in the understanding of relationships among the brain and the functions of the endocrine, autonomic, and immune systems. We emphasize the effects of environmental experiences related to caregiver relationships because it is these experiences, in particular, that shape regulatory and threat response systems in ways that increase vulnerability and may underlie the wide range of poor outcomes associated with early adversity. Thus, we metaphorically extend the concept of plasticity to highlight our goal of a broader consideration of these interconnected mechanisms. We conclude by discussing implications for neurobiologically informed interventions that can potentially ameliorate the broad and costly effects of early adversity.

OBJECTIVE: The current study was guided by Nigrescence theory (Cross, 1971, 1991) and explored the phenomenon of racial awakening or epiphanic experiences of Black adults. We were interested in describing the context and perceived outcomes of the epiphanies in participants' understanding of what it means to be Black. METHOD: Sixty-four adults participated in racial life narrative interviews. There was an equivalent number of men and women who participated from 4 sites: Australia, Bermuda, South Africa, and the United States. RESULTS: Findings from dimensional analysis highlight the turning points, triggers, and awakening or epiphanies in one's racial identity. Specifically, in this study racial awakening or increased awareness about the meaning of being Black was spurred by personal experiences and/or observations, education, and activism. Participants discussed increased racial activism, racial pride, and possible-selves after the process of racial awakening and continued exploration. Only 1 participant described disappointment and despair after a racial epiphany. CONCLUSIONS: Findings extend our understanding of the process in which people develop a sense of racial consciousness. Insights may help inform future researchers in terms of identifying racial awakening prototypic stories and counselors in terms of providing opportunities to assist individuals in the meaning-making process.

The relationship between early adversity and numerous negative outcomes across the lifespan is evident in a wide range of societies and cultures (e.g., Pakulak, Stevens, & Neville, 2018). Among the most affected neural systems are those supporting attention, self-regulation, and stress regulation. As such, these systems represent targets for neurobiologically informed interventions addressing early adversity. In prior work with monolingual native English-speaking families, we showed that a two-generation intervention targeting these systems in families improves outcomes across multiple domains including child brain function for selective attention (for detail, see Neville et al., 2013). Here, we discuss the translation and cultural adaptation (CA) of this intervention in local and international contexts, which required systematic consideration of cultural differences that could affect program acceptability. First, we conducted a translation and CA of our program to serve Latino families in the United States using the Cultural Adaptation Process (CAP), a model that works closely with stakeholders in a systematic, iterative process. Second, to implement the adapted program in Medellín, Colombia, we conducted a subsequent adaptation for Colombian culture using the same CAP. Our experience underscores the importance of consideration of cultural differences and a systematic approach to adaptation before assessing the efficacy of neurobiologically informed interventions in different cultural contexts.

Evolutionary and ecological consequences of hybridization between native and invasive species are notoriously complicated because patterns of selection acting on non-native alleles can vary throughout the genome and across environments. Rapid advances in genomics now make it feasible to assess locus-specific and genome-wide patterns of natural selection acting on invasive introgression within and among natural populations occupying diverse environments. We quantified genome-wide patterns of admixture across multiple independent hybrid zones of native westslope cutthroat trout and invasive rainbow trout, the world's most widely introduced fish, by genotyping 339 individuals from 21 populations using 9380 species-diagnostic loci. A significantly greater proportion of the genome appeared to be under selection favouring native cutthroat trout (rather than rainbow trout), and this pattern was pervasive across the genome (detected on most chromosomes). Furthermore, selection against invasive alleles was consistent across populations and environments, even in those where rainbow trout were predicted to have a selective advantage (warm environments). These data corroborate field studies showing that hybrids between these species have lower fitness than the native taxa, and show that these fitness differences are due to selection favouring many native genes distributed widely throughout the genome.

Selective attention, the ability to enhance the processing of particular input while suppressing the information from other concurrent sources, has been postulated to be a foundational skill for learning and academic achievement. The neural mechanisms of this foundational ability are both vulnerable and enhanceable in children from lower socioeconomic status (SES) families. In the current study, we assessed individual differences in neural mechanisms of this malleable brain function in children from lower SES families. Specifically, we investigated the extent to which individual differences in neural mechanisms of selective auditory attention accounted for variability in nonverbal cognitive abilities in lower SES preschoolers. We recorded event-related potentials (ERPs) during a dichotic listening task and administered nonverbal IQ tasks to 124 lower SES children (77 females) between the ages of 40 and 67 months. The attention effect, i.e., the difference in ERP mean amplitudes elicited by identical probes embedded in stories when attended versus unattended, was significantly correlated with nonverbal IQ scores. Larger, more positive attention effects over the anterior and central electrode locations were associated with superior nonverbal IQ performance. Our findings provide initial evidence for prominent individual differences in neural indices of selective attention in lower SES children. Furthermore, our results indicate a noteworthy relationship between neural mechanisms of selective attention and nonverbal IQ performance in lower SES preschoolers. These findings provide the basis for future research to identify the factors that contribute to such individual differences in neural mechanisms of selective attention.

Using information from research on the neuroplasticity of selective attention and on the central role of successful parenting in child development, we developed and rigorously assessed a family-based training program designed to improve brain systems for selective attention in preschool children. One hundred forty-one lower socioeconomic status preschoolers enrolled in a Head Start program were randomly assigned to the training program, Head Start alone, or an active control group. Electrophysiological measures of children's brain functions supporting selective attention, standardized measures of cognition, and parent-reported child behaviors all favored children in the treatment program relative to both control groups. Positive changes were also observed in the parents themselves. Effect sizes ranged from one-quarter to half of a standard deviation. These results lend impetus to the further development and broader implementation of evidence-based education programs that target at-risk families.

The purpose of this study was to develop a measure of gendered racial microaggressions (i.e., subtle and everyday verbal, behavioral, and environmental expressions of oppression based on the intersection of one's race and gender) experienced by Black women by applying an intersectionality framework to Essed's (1991) theory of gendered racism and Sue, Capodilupo, et al.'s (2007) model of racial microaggressions. The Gendered Racial Microaggressions Scale (GRMS), was developed to assess both frequency and stress appraisal of microaggressions, in 2 separate studies. After the initial pool of GRMS items was developed, we received input from a community-based focus group of Black women and an expert panel. In Study 1, an exploratory factor analysis using a sample of 259 Black women resulted in a multidimensional scale with 4 factors as follows: (a) Assumptions of Beauty and Sexual Objectification, (b) Silenced and Marginalized, (c) Strong Black Woman Stereotype, and (d) Angry Black Woman Stereotype. In Study 2, results of confirmatory factor analyses using an independent sample of 210 Black women suggested that the 4-factor model was a good fit of the data for both the frequency and stress appraisal scales. Supporting construct validity, the GRMS was positively related to the Racial and Ethnic Microaggressions Scale (Nadal, 2011) and the Schedule of Sexist Events (Klonoff & Landrine, 1995). In addition, the GRMS was significantly related to psychological distress, such that greater perceived gendered racial microaggressions were related to greater levels of reported psychological distress. Implications for future research and practice are discussed.
