RESUMEN
OBJECTIVE: Modified Mini-Mental State Examination (3MSE) is often used to screen for dementia, but little is known about psychometric validity in American Indians. METHODS: We recruited 818 American Indians aged 65-95 for 3MSE examinations in 2010-2013; 403 returned for a repeat examination in 2017-2019. Analyses included standard psychometrics inferences for interpretation, generalizability, and extrapolation: factor analysis; internal consistency-reliability; test-retest score stability; multiple indicator multiple cause structural equation models. RESULTS: This cohort was mean age 73, majority female, mean 12 years education, and majority bilingual. The 4-factor and 2nd-order models fit best, with subfactors for orientation and visuo-construction (OVC), language and executive functioning (LEF), psychomotor and working memory (PMWM), verbal and episodic memory (VEM). Factor structure was supported for both research and clinical interpretation, and factor loadings were moderate to high. Scores were generally consistent over mean 7 years. Younger participants performed better in overall scores, but not in individual factors. Males performed better on OVC and LEF, females better on PMWM. Those with more education performed better on LEF and worse on OVC; the converse was true for bilinguals. All differences were significant, but small. CONCLUSION: These findings support use of 3MSE for individual interpretation in clinic and research among American Indians, with moderate consistency, stability, reliability over time. Observed extrapolations across age, sex, education, and bilingual groups suggest some important contextual differences may exist.

INTRODUCTION: Research on factors associated with late-life cognitive performance in diverse racial/ethnic groups is increasingly important due to the growing size and racial diversity of the elder population. METHODS: Using data on American Indians (AIs) from the Strong Heart Study, we measured associations between mid-life physical activity (PA), assessed by a questionnaire or pedometer, and performance on tests of general cognitive function, phonemic fluency, verbal learning and memory, and processing speed. Cognitive tests were administered 7-21 years after PA measurements. To estimate associations, we used regression models with and without inverse-probability weights to account for potential attrition bias in the cohort. RESULTS: Questionnaire and pedometer measures of PA were positively associated with cognitive function. Participants in the top quartile of questionnaire-based PA had Modified Mini-Mental State examination scores 3.2 (95% CI: 1.5-4.9) points higher than participants in the lowest quartile. Phonemic fluency scores also trended higher for participants in the top compared to the bottom categories for both PA measures: top questionnaire quartile = 2.7 (95% CI: 0.6-4.8) points higher and top pedometry tertile = 6.7 (95% CI: 2.7-10.7) points higher. We observed no associations between PA and tests assessing verbal learning and memory, or processing speed. Weighted model results were similar, but less precise. CONCLUSIONS: In this cohort of AIs with relatively low levels of PA, positive associations between mid-life PA and late-life cognitive performance were dose-dependent and of modest clinical significance.

BACKGROUND: American Indian elders, aged 55 years and older, represent a neglected segment of the United States (U.S.) health care system. This group is more likely to be uninsured and to suffer from greater morbidities, poorer health outcomes and quality of life, and lower life expectancies compared to all other aging populations in the country. Despite the U.S. government's federal trust responsibility to meet American Indians' health-related needs through the Indian Health Service (IHS), elders are negatively affected by provider shortages, limited availability of health care services, and gaps in insurance. This qualitative study examines the perspectives of professional stakeholders involved in planning, delivery of, and advocating for services for this population to identify and analyze macro- and meso-level factors affecting access to and use of health care and insurance among American Indian elders at the micro level. METHODS: Between June 2016 and March 2017, we undertook in-depth qualitative interviews with 47 professional stakeholders in two states in the Southwest U.S., including health care providers, outreach workers, public-sector administrators, and tribal leaders. The interviews focused on perceptions of both policy- and practice-related factors that bear upon health care inequities impacting elders. We analyzed iteratively the interview transcripts, using both open and focused coding techniques, followed by a critical review of the findings by a Community Action Board comprising American Indian elders. RESULTS: Findings illuminated complex and multilevel contextual influences on health care inequities for elders, centering on (1) gaps in elder-oriented services; (2) benefits and limits of the Affordable Care Act (ACA); (2) invisibility of elders in national, state, and tribal policymaking; and (4) perceived threats to the IHS system and the federal trust responsibility. CONCLUSIONS: Findings point to recommendations to improve the prevention and treatment of illness among American Indian elders by meeting their unique health care and insurance needs. Policies and practices must target meso and macro levels of contextual influence. Although Medicaid expansion under the ACA enables providers of essential services to elders, including the IHS, to enhance care through increased reimbursements, future policy efforts must improve upon this funding situation and fulfill the federal trust responsibility.

Traditional non-participatory research methodologies have struggled to address the needs of multicultural populations in the United States (U.S.). Community-based participatory research (CBPR) is a research paradigm offering a unique opportunity for culturally appropriate research and improving health equity. CBPR is an equitable, strength-based approach involving all stakeholders throughout the research process. We investigate the field of psychology's utilization of CBPR as an approach for working with multicultural populations to collaboratively address relevant and impactful research questions. A total of 1912 CBPR-related articles, from 2004 to 2014, were identified using PsycINFO, PubMed, and CINAHL Complete databases. Of these, approximately 16% (n = 311) met our criteria for psychology-related CBPR articles accounting for a negligible amount (<1%) of peer-reviewed publications in mainstream psychological journals during the same time period. Among U.S. psychology-related CBPR articles, 86% focused on multicultural and marginalized populations. Prominent topics of investigation included physical health, mental and behavioral health, and theoretical or methodological articles. Features of publications, including authors' training, types of journals, study populations, and topics under investigation, were explored for all 1912 publications. Findings highlight an opportunity for further utilization of CBPR within psychology, with key implications for health equity. Recommendations for increasing CBPR uptake within the discipline are also offered.

OBJECTIVE: American Indians experience substantial health disparities relative to the US population, including vascular brain aging. Poorer cognitive test performance has been associated with cranial magnetic resonance imaging findings in aging community populations, but no study has investigated these associations in elderly American Indians. METHODS: We examined 786 American Indians aged 64 years and older from the Cerebrovascular Disease and its Consequences in American Indians study (2010-2013). Cranial magnetic resonance images were scored for cortical and subcortical infarcts, hemorrhages, severity of white matter disease, sulcal widening, ventricle enlargement, and volumetric estimates for white matter hyperintensities (WMHs), hippocampus, and brain. Participants completed demographic, medical history, and neuropsychological assessments including testing for general cognitive functioning, verbal learning and memory, processing speed, phonemic fluency, and executive function. RESULTS: Processing speed was independently associated with the presence of any infarcts, white matter disease, and hippocampal and brain volumes, independent of socioeconomic, language, education, and clinical factors. Other significant associations included general cognitive functioning with hippocampal volume. Nonsignificant, marginal associations included general cognition with WMH and brain volume; verbal memory with hippocampal volume; verbal fluency and executive function with brain volume; and processing speed with ventricle enlargement. CONCLUSIONS: Brain-cognition associations found in this study of elderly American Indians are similar to those found in other racial/ethnic populations, with processing speed comprising an especially strong correlate of cerebrovascular disease. These findings may assist future efforts to define opportunities for disease prevention, to conduct research on diagnostic and normative standards, and to guide clinical evaluation of this underserved and overburdened population.

OBJECTIVES: Insulin resistance is a substantial health issue for American Indians, with type 2 diabetes overrepresented in this population as compared with non-Hispanic whites. Insulin resistance and its related conditions in turn increase risk for dementia and cognitive impairment. The aim of the current study was to determine whether type 2 diabetes and insulin resistance at midlife was associated with later-life cognitive testing in a large sample of older American Indians, aged 65 and older. METHODS: American Indian participants who underwent both fasting blood draw as part of the Strong Heart Study and had subsequent cognitive testing as part of the later adjunct Cerebrovascular Disease and its Consequences in American Indians study were included (n = 790). Regression models examined type 2 diabetes and impaired fasting glucose and subsequent cognitive test performance as part of a longitudinal study design. The relationship between a continuous measure of insulin resistance and later cognitive test performance was assessed using generalized estimating equations. RESULTS: Controlling for demographic and clinical factors, verbal fluency and processing speed/working memory were significantly negatively associated with having type 2 diabetes and with insulin resistance, but not with impaired fasting glucose. CONCLUSION: In this sample of American Indians, type 2 diabetes at midlife was associated with subsequent lower performance on measures of executive function. These results may have important implications for future implementation of diagnostic and intervention services in this population.

OBJECTIVE: Health literacy is critical for understanding information from health-care providers and correct use of medications and includes the capacity to filter other information in navigating health care systems. Older adults with low health literacy exhibit more chronic health conditions, worse physical functioning, and poorer mental health. This study examined the relationship between sociodemographic variables and health literacy, and the impact of cognitive training on change in health literacy over 10 years in older adults. METHODS: Participants (N = 2,802) aged 65 years and older completed assessments, including reading and numeracy health literacy items, as part of the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study. We evaluated baseline sociodemographic variables and change in health literacy over a 10-year period in individuals exposed to cognitive training in reasoning, processing speed, memory, or a no-contact control condition. RESULTS: Age, sex, race, education level, and general cognitive functioning at baseline were all associated with baseline health literacy in older adults. Predictors of change in health literacy over the 10-year follow-up were age, race, education level, general cognitive functioning, and neighborhood income; disparities in health literacy because of race attenuated over time, while the effect of age increased over time. Health literacy was generally stable across the ACTIVE intervention groups over 10 years. CONCLUSIONS: The present study showed important disparities in health literacy level and change over 10 years. Cognitive training did not significantly impact health literacy, suggesting that alternative approaches are needed to reduce the disparities.

INTRODUCTION: The present study sought to determine whether cognitive trajectories differ between men and women across and within racial/ethnic groups. METHODS: Participants were 5258 non-Hispanic White (NHW), Black, and Hispanic men and women in the Washington/Hamilton Heights-Inwood Columbia Aging Project who were administered neuropsychological tests of memory, language, and visuospatial abilities at 18- to 24-month intervals for up to 25 years. Multiple-group latent growth curve modeling examined trajectories across sex/gender by race/ethnicity. RESULTS: After adjusting for age and education, the largest baseline differences were between NHW men and Hispanic women on visuospatial and language, and between NHW women and Black men on memory. Memory and visuospatial decline was steeper for Black women compared with Hispanic men and NHW women, respectively. DISCUSSION: This study takes an important first step in understanding interactions between race/ethnicity and sex/gender on cognitive trajectories by demonstrating variability in sex/gender differences across race/ethnicity.

BACKGROUND: More than six million American Indians live in the United States, and an estimated 1.6 million will be aged ≥65 years old by 2050 tripling in numbers since 2012. Physical functioning and related factors in this population are poorly understood. Our study aimed to assess lower body functioning and identify the prevalence and correlates of "good" functioning in a multi-tribe, community-based sample of older American Indians. METHODS: Assessments used the Short Physical Performance Battery (SPPB). "Good" lower body functioning was defined as a total SPPB score of ≥10. Potential correlates included demographic characteristics, study site, anthropometrics, cognitive functioning, depressive symptomatology, grip strength, hypertension, diabetes mellitus, heart disease, prior stroke, smoking, alcohol use, and over-the-counter medication use for arthritis or pain. Data were collected between 2010 and 2013 by the Cerebrovascular Disease and Its Consequences in American Indians Study from community-dwelling adults aged ≥60 years (n = 818). RESULTS: The sample's mean age was 73 ± 5.9 years. After adjustment for age and study site, average SPPB scores were 7.0 (95% CI, 6.8, 7.3) in women and 7.8 (95% CI, 7.5, 8.2) in men. Only 25% of the sample were classified with "good" lower body functioning. When treating lower body functioning as a continuous measure and adjusting for age, gender, and study site, the correlates of better functioning that we identified were younger age, male gender, married status, higher levels of education, higher annual household income, Southern Plains study site, lower waist-hip ratio, better cognitive functioning, stronger grip strength, lower levels of depressive symptomatology, alcohol consumption, and the absence of hypertension, diabetes mellitus, and heart disease. In our fully adjusted models, correlates of "good" lower body functioning were younger age, higher annual household income, better cognitive functioning, stronger grip, and the absence of diabetes mellitus and heart disease. CONCLUSIONS: These results suggest that "good" lower body functioning is uncommon in this population, whereas its correlates are similar to those found in studies of other older adult populations. Future efforts should include the development or cultural tailoring of interventions to improve lower body functioning in older American Indians.

BACKGROUND: Public insurance reforms of the past two decades have failed to substantively address the healthcare needs of American Indians in general, let alone the particular needs of American Indian elders, ages 55 years and older. Historically, this population is more likely to be uninsured and to suffer from greater morbidities, poorer health outcomes and quality of life, and lower life expectancies compared to all other United States aging populations, representing a neglected group within the healthcare system. Despite the pervasive belief that the Indian Health Service will address all their health-related needs, American Indian elders are negatively affected by gaps in insurance and lack of access to health care. While the 2010 Patient Protection and Affordable Care Act included provisions to ameliorate disparities for American Indians, its future is uncertain. In this context, American Indian elders with variable health literacy must navigate a complex and unstable healthcare system, regardless of where they seek care. METHODS: This community-driven study features a mixed-method, participatory design to examine help-seeking behavior and healthcare experiences of American Indian elders in New Mexico, in order to develop and evaluate a tailored intervention to enhance knowledge of, access to, and use of insurance and available services to reduce healthcare disparities. This study includes qualitative and quantitative interviews combined with concept mapping and focus groups with American Indian elders and other key stakeholders. DISCUSSION: The information gathered will generate new practical knowledge, grounded in actual perspectives of American Indian elders and other relevant stakeholders, to improve healthcare practices and policies for a population that has been largely excluded from national and state discussions of healthcare reform. Study data will inform development and evaluation of culturally tailored programming to enhance understanding and facilitate negotiation of the changing landscape of health care by American Indian elders. This work will fill a gap in research on public insurance initiatives, which do not typically focus on this population, and will offer a replicable model for enhancing the effects of such initiatives on other underserved groups affected by healthcare inequities. TRIAL REGISTRATION: This protocol does not include the collection of health outcome data. Clinicaltrials.gov, NCT03550404 . Registered June 6, 2018.

BACKGROUND: Estimates of hippocampal volume by magnetic resonance imaging have clinical and cognitive correlations and can assist in early Alzheimer disease diagnosis. However, little is known about the relationship between global or regional brain volumes and cognitive test performance in American Indians. MATERIALS AND METHODS: American Indian participants (N=698; median age, 72 y) recruited for the Cerebrovascular Disease and its Consequences in American Indians study, an ancillary study of the Strong Heart Study cohort, were enrolled. Linear regression models assessed the relationship between magnetic resonance imaging brain volumes (total brain and hippocampi) and cognitive measures of verbal learning and recall, processing speed, verbal fluency, and global cognition. RESULTS: After controlling for demographic and clinical factors, all volumetric measurements were positively associated with processing speed. Total brain volume was also positively associated with verbal learning, but not with verbal recall. Conversely, left hippocampal volume was associated with both verbal learning and recall. The relationship between hippocampal volume and recall performance was more pronounced among those with lower scores on a global cognitive measure. Controlling for APOE ε4 did not substantively affect the associations. CONCLUSIONS: These results support further investigation into the relationship between structural Alzheimer disease biomarkers, cognition, genetics, and vascular risk factors in aging American Indians.

BACKGROUND: Inorganic arsenic at high and prolonged doses is highly neurotoxic. Few studies have evaluated whether long-term, low-level arsenic exposure is associated with neuropsychological functioning in adults. OBJECTIVES: To investigate the association between long-term, low-level inorganic arsenic exposure and neuropsychological functioning among American Indians aged 64-95. METHODS: We assessed 928 participants in the Strong Heart Study by using data on arsenic species in urine samples collected at baseline (1989-1991) and results of standardized tests of global cognition, executive functioning, verbal learning and memory, fine motor functioning, and speed of mental processing administered during comprehensive follow-up evaluations in 2009-2013. We calculated the difference in neuropsychological functioning for a 10% increase in urinary arsenic with adjustment for sex, age, education, and study site. RESULTS: The sum of inorganic and methylated arsenic species (∑As) in urine was associated with limited fine motor functioning and processing speed. A 10% increase in ∑As was associated with a .10 (95% CI -.20, -.01) decrease on the Finger Tapping Test for the dominant hand and a .13 decrease (95% CI -.21, -.04) for the non-dominant hand. Similarly, a 10% increase in ∑As was associated with a .15 (95% CI -.29, .00) decrease on the Wechsler Adult Intelligence Scale-Fourth Edition Coding Subtest. ∑As was not associated with other neuropsychological functions. CONCLUSIONS: Findings indicate an adverse association between increased urinary arsenic fine motor functioning and processing speed, but not with other neuropsychological functioning, among elderly American Indians.

The Cerebrovascular Disease and its Consequences in American Indians (CDCAI) Study recruited surviving members of a 20-year, longitudinal, population-based cohort of American Indians focused on cardiovascular disease, its risk factors, and its consequences. The goal of the CDCAI Study is to characterize the burden, risk factors, and manifestations of vascular brain injury identified on cranial MRI. The CDCAI Study investigators enrolled 1,033 participants aged 60 and older from 11 American Indian communities and tribes in the Northern Plains, Southern Plains, and Southwestern United States. In addition to cranial MRI performed according to standardized protocols, participants underwent extensive medical interview, clinical examination, neurocognitive testing, physical function evaluation, electrocardiogram, and provided blood and urine specimens. Participants also self-administered questionnaires covering demographics, quality of life, and medical history. This report describes the design, implementation, and some of the unique challenges of this study and data collection.

Addressing systemic injustices and racism in training and clinical service provision are key next steps in clinical science. While the APA Multicultural Guidelines and accreditation standards have long emphasized this need, most graduate programs offer a single course on diversity, equity, and inclusion topics, which is inadequate to train and sustain culturally humble providers and redress systemic injustices and racism within psychology. Few "real-world" examples exist to guide the development of training models. We provide background on the development and components of a specialty clinic, the University of New Mexico's Cultural Counseling Center, whose mission is providing culturally informed clinical services to diverse clientele, and to infuse multicultural training throughout the graduate program. Informed by the racial-spatial framework for psychology and critical race theory, we describe our approach intended to: 1) offer applications for the operationalization and delivery of multicultural and antiracist training; 2) enhance supervisory models; and 3) increase awareness of structural competence. Our clinic, developed collaboratively among students and faculty, serves as a safe forum for dialogue around structural injustices and seeks to improve treatment for diverse clients and those underserved in mental health care. We discuss issues of student and faculty engagement and offer the perspectives of faculty and students of color, case examples illustrating our services, and current efforts to expand and formalize community collaborations. We offer a model that integrates coursework, informal activities, and multicultural supervision for comprehensive student training and that promotes a departmental culture of dialogue and support around equity, diversity, and justice.
RESUMEN
OBJECTIVE: This study describes trajectories of cognitive aging among American Indian/Alaskan Native (AI/AN) adults with and without HIV and the role of immunosenescence longitudinally. METHOD: We characterized trajectories of cognitive aging in a sample of 333 AI/AN and 309 non-Hispanic White (NHW) adults who were followed longitudinally for up to 20 years by the HIV Neurobehavioral Research Program (HNRP) across six U.S. research sites. We used growth curve modeling with autoregressive Lag-1 structures and heterogeneous residual variances to assess the role of ethnoracial identity and HIV grouping upon decline in trajectories of cognitive aging. RESULTS: HIV- AI/AN adults demonstrated earlier and steeper decline in normative trajectories of cognitive aging on tasks of processing speed, timed tasks of attention/working memory, executive function, and psychomotor speed in comparison to HIV- NHW adults. Accentuated trajectories of cognitive aging were evident in both HIV+ and HIV+ immunosuppressed groups in comparison to HIV- peers and were primarily driven by the role of immunosenescence. CONCLUSIONS: AI/AN disparities in trajectories of cognitive aging are evident and are likely explained by the interplay of biopsychosociocultural factors, including immunosenescence.

RESUMEN
Intersectionality and minority stress frameworks were used to guide examination and comparisons of psychological distress (depression, anxiety, posttraumatic stress disorder symptoms) and protective factors (religiosity, spirituality, social support) among 673 Black, Latinx, and White lesbian and bisexual women with and without histories of sexual assault. Participants were from Wave 3 of the 21-year longitudinal Chicago Health and Life Experiences of Women (CHLEW) study. More than one-third (38%) of participants reported having experienced adolescent or adult sexual assault (i.e., rape or another form of sexual assault) since age 14. Confirmatory factor analysis, structural equation modeling, and multivariate analyses of covariance were used to analyze the data. Results revealed that levels of religiosity/spirituality and psychological distress varied by race/ethnicity and by sexual identity (i.e., Black lesbian, Black bisexual, Latinx lesbian, Latinx bisexual, White lesbian, White bisexual). Black lesbian women reported the highest level of religiosity/spirituality whereas White lesbian women reported the lowest level. White bisexual women reported the highest level of psychological distress whereas White lesbian women reported the lowest level. We found no significant differences in reports of sexual assault or in social support (i.e., significant other, family, friend, and total social support). However, White lesbian women had higher friend, significant other, and total social support relative to the other five groups of women with minoritized/marginalized sexual identities. Future work should examine whether religiosity, spirituality, and social support serve as protective factors that can be incorporated into mental health treatment for lesbian and bisexual who have experienced sexual assault to reduce psychological distress.

Information about the equality of psychometric properties of the medical outcomes study (MOS) Short Form-36 (SF-36), a health status measure, across gender and across the lifespan for American Indian adults is lacking. We tested measurement invariance (configural, metric, scalar invariance) of the physical and mental components between gender and over time in a sample of 2,709 (1,054 men, 1,654 women) American Indian older adults at three time points, and across a 6-year time frame. Measurement invariance of a 2-factor higher-order model was demonstrated between gender at each time point. Tests of longitudinal invariance indicated longitudinal measurement invariance over time. Multiple-group latent means analysis indicated men had significantly higher physical and mental component latent means compared to women at each time point, and longitudinal latent means analysis found physical and mental component latent means decreased over time. The 2-factor higher-order model SF-36 is valid for American Indian older adults over a 6-year time frame. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

In the context of recent policies aimed at deterring immigration and criminalizing undocumented Latino immigrants, we examined factors predicting implicit and explicit attitudes toward this population. We hypothesized that more positive implicit and explicit attitudes toward undocumented Latino immigrants would be displayed by Latinxs (compared to non-Hispanic Whites) and by individuals having personal connections to undocumented immigrants or a high level of intercultural sensitivity. Latinx (n = 376) and non-Hispanic White (n = 214) college students (70% female, M age = 21) participated in this cross-sectional study and completed two Implicit Association Tests and measures of explicit attitudes, personal connections, and intercultural sensitivity. As predicted, Latinx participants held more positive implicit and explicit attitudes than non-Hispanic White participants. Intercultural sensitivity and personal connections to undocumented immigrants were associated with more positive explicit attitudes. Identifying factors that increase a sense of commonality and cultural sensitivity with undocumented Latino immigrants may be helpful in diminishing the profiling and criminalization of this community.
RESUMEN
Social support protects against perceived stress and its harmful effects on psychological well-being. College students in general are at high risk for mental health disorders, and Latinx college students face unique stressors placing them at greater risk of psychological distress. Social support may be a key construct in improving outcomes for college students; however, few studies have empirically tested whether the protective effect of social support is equivalent across racial/ethnic groups. Using a series of regression models, we investigated whether social support moderates the relationship between perceived stress and endorsement of depression and anxiety symptoms in Latinx (n = 265) and non-Latinx White college students (n = 216) and whether this moderating effect varied by group membership. Participants completed a series of questionnaires measuring social support, perceived stress, and depression and anxiety symptoms. The moderating effects of social support varied by group membership and outcomes (i.e., depression and anxiety). Social support moderated the relationship between perceived stress and depression symptoms for both Latinx and non-Latinx White students. However, social support only buffered the effect of perceived stress on anxiety symptom endorsement for Latinx college students. These findings suggest that social support does not function uniformly across racial/ethnic groups or the endorsement of depression and anxiety symptoms. Social support may be particularly important for Latinx students by providing a buffer between perceived stress and symptoms of anxiety.
El apoyo social protege contra el estrés y sus efectos en el bienestar psicológico. El riesgo de desarrollar trastornos psicológicos es elevado en estudiantes universitarios. Estudiantes universitarios Latinxs enfrentan situaciones relacionadas con identificatión de minoría que pueden contribuir a una elevación en el riesgo de desarrollar problemas psicológicos. Como tal, el apoyo social es un área clave para la preventión y mejoría del bienestar psicológico. Sin embargo, pocas investigaciones han comparado los efectos protectores del apoyo social a través de raza y etnia. Usamos una serie de modelos de regresión para investigar si el apoyo social modera la relación entre la percepción de estrés y el reporte de síntomas de depresión y ansiedad en estudiantes universitarios Latinxs y anglosajones. Además, investigamos si este efecto de moderación varia en dependencia de la membresía etnia. Participantes completaron una serie de cuestionarios midiendo variables de interés, incluyendo apoyo social, percepcicón de estrés, síntomas de depresión y ansiedad. El apoyo social modera la relación entre la percepcición de estrés y síntomas de depresión en los dos grupos étnicos, Latinxs y anglosajones. Sin embargo, para los síntomas de ansiedad, el efecto protector del apoyo social fue distinto para los estudiantes Latinxs. Estos resultados sugieren que la función del apoyo social no es uniforme a través de grupos étnicos o en términos de protectión contra diferentes problemas psicológicos. El apoyo social es particularmente importante para los estudiantes Latinxs en términos de proveer protectión contra síntomas de ansiedad en la presencia de la perceptión del estrés.
RESUMEN
The validation of the assessment of depression across ethnic groups is critical yet deficient for American Indian (AI) adults. Therefore, we assessed the psychometric properties of the Center for Epidemiological Studies-Depression (CES-D) in AI elders and tested differences in depression constructs between gender. Participants were 817 AI adults (68% women), mean age 73.2 years (SD = 6.1, range: 64-95) for women and 72.6 years (SD = 5.3, range: 65-90) for men., in the Cerebrovascular Disease and Its Consequences in AIs Study. We evaluated the factor structure of the 20-item and 12-item CES-D and tested measurement invariance between gender. Results demonstrated a poor fit for the 20-item CES-D and partial gender measurement invariance of the 12-item CES-D. AI female elders had significantly higher depression levels than AI male elders on the Depressed Affect subscale, the Somatic Symptoms subscale, and the Well-Being (reverse-coded) subscale. Further replication is needed, and we recommend future psychometric work with the 12-item CES-D with AI elders. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
