Measurement issues in health disparities research

Ethno-racial differences in depressive symptom endorsement: Evaluation of brief forms of the Geriatric Depression Scale in older adults

BACKGROUND

Depression among older adults is a pressing public health concern, necessitating accurate assessment tools. The Geriatric Depression Scale (GDS) offers a brief and efficient means of screening depressive symptoms, yet its performance across ethno-racial groups remains understudied. This study aimed to compare the ability of various brief forms of the GDS to detect depressive symptoms and to assess potential ethno-racial differences in symptom endorsement among White, Black/African-American, and American Indian/Alaska Native older adults.

METHODS

Data were obtained from the Wisconsin Alzheimer's Disease Research Center (ADRC) clinical cohort, comprising 555 cognitively healthy individuals at risk for dementia. We used participants' baseline data for this cross-sectional analysis. Depressive symptoms were assessed using multiple brief forms of the GDS, derived from a systematic review and meta-analysis. We examined internal consistency and correlations with global Clinical Dementia Rating (CDR) scores. We conducted Kruskal-Wallis tests and post hoc pairwise comparisons to assess ethno-racial group differences in symptom endorsement.

RESULTS

Descriptive statistics revealed a predominance of female and White participants, with notable representation from Black and American Indian/Alaska Native groups. All GDS versions demonstrated moderate to high internal consistency. Significant positive correlations were observed between GDS scores and global CDR scores. Ethno-racial group differences in depressive symptom endorsement were evident, with Black participants consistently reporting higher levels of symptoms across most GDS versions. However, American Indian/Alaska Native participants endorsed significantly fewer symptoms than Black participants in one GDS version.

CONCLUSION

The study highlights the importance of considering ethno-racial differences in depressive symptomatology when assessing older adults. While the GDS demonstrates overall reliability, variations in symptom endorsement across different ethno-racial groups underscore the need for culturally sensitive assessment tools and interventions. Future research should further explore these group differences and develop tailored approaches to depression screening and treatment in diverse older adult populations.

Operationalizing Equity, Inclusion, and Access in Research Practice at a Large Academic Institution

INTRODUCTION

Healthcare advances are hindered by underrepresentation in prospective research; sociodemographic, data, and measurement infidelity in retrospective research; and a paucity of guidelines surrounding equitable research practices.

OBJECTIVE

The Joint Research Practices Working Group was created in 2021 to develop and disseminate guidelines for the conduct of inclusive and equitable research.

METHODS

Volunteer faculty and staff from two research centers at the University of Pennsylvania initiated a multi-pronged approach to guideline development, including literature searches, center-level feedback, and mutual learning with local experts.

RESULTS

We developed guidelines for (1) participant payment and incentives; (2) language interpretation and translation; (3) plain language in research communications; (4) readability of study materials; and (5) inclusive language for scientific communications. Key recommendations include (1) offer cash payments and multiple payment options to participants when required actions are completed; (2) identify top languages of your target population, map points of contact, and determine available interpretation and translation resources; (3) assess reading levels of materials and simplify language, targeting 6th- to 8th-grade reading levels; (4) improve readability through text formatting and style, symbols, and visuals; and (5) use specific, humanizing terms as adjectives rather than nouns.

CONCLUSIONS

Diversity, inclusion, and access are critical values for research conduct that promotes justice and equity. These values can be operationalized through organizational commitment that combines bottom-up and top-down approaches and through partnerships across organizations that promote mutual learning and synergy. While our guidelines represent best practices at one time, we recognize that practices evolve and need to be evaluated continuously for accuracy and relevance. Our intention is to bring awareness to these critical topics and form a foundation for important conversations surrounding equitable and inclusive research practices.

Receipt and duration of buprenorphine treatment during pregnancy and postpartum periods in a national privately-insured cohort

Background

Research gaps exist on the use of medications for opioid use disorder (OUD) among birthing people.

Methods

This retrospective cohort study included people who underwent childbirth deliveries during 2017-2020 and had a diagnosis of OUD identified from a national private insurance claims database. Buprenorphine prescriptions received during the year before childbirth and the year after childbirth were obtained from pharmacy claims. Logistic regressions were used to estimate associations between receipt of buprenorphine and individual and state-level factors.

Results

Among a sample of 1,523 birthing people diagnosed with OUD, 540 (35.5 %) received buprenorphine during the pregnancy or postpartum periods. About half (51.5 %) of new recipients of buprenorphine received treatment for at least six months and, of those, one-third experienced a treatment interruption. The buprenorphine receipt rate differed significantly by race and ethnicity: 28.8 % of non-Hispanic Black birthing people with OUD and 22.8 % of Hispanic birthing people with OUD received buprenorphine treatment in contrast to 37.7 % of non-Hispanic white birthing people (aOR 0.53 [95 % CI 0.35-0.81] and 0.59 [95 % CI 0.37-0.96], respectively). The buprenorphine use rate increased over time from 29.7 % in 2017 to 42.9 % in 2020. Birthing people living in states with punitive policies related to substance use in pregnancy had the lowest buprenorphine use rate of 22.7 % as compared to 43.0 % in states with least restrictive policies.

Conclusion

In this national sample of privately-insured individuals, by 2020, 42.9 % of birthing people with OUD received buprenorphine treatment. Treatment discontinuation and interruptions were common in the period surrounding childbirth.

Unexpected lucidity in dementia: application of qualitative methods to develop an informant-reported lucidity measure

OBJECTIVES

Unexpected lucidity is a phenomenon of scientific, clinical, and psychological relevance to health professionals, to those who experience it, and their relatives. This paper describes qualitative methods used to develop an informant-based measure of lucidity episodes.

METHODS

The approach was refinement of the operationalization of the construct; review of seminal items, modification, and purification; and confirmation of the feasibility of reporting methodology. Modified focus groups were conducted with 20 staff and 10 family members using a web-based survey. Themes included reaction when hearing the term; words that come to mind; description of and first reaction to referenced or observed 'lucidity' events. Semi-structured cognitive interviews were conducted with 10 health professionals working with older adults with cognitive impairment. Data were extracted from Qualtrics or Microsoft 365 Word® for analysis using NVivo.

RESULTS

Conceptual issues, as well as issues regarding comprehension, interpretation, clarity, semantics, and standardization of definitions derived from an external advisory board, focus groups and cognitive interviews informed items' modification, and resulted in the final lucidity measure.

CONCLUSIONS

An obstacle to understanding the mechanisms and estimating the prevalence of lucid events among individuals with dementia and other neurological conditions is the scarcity of reliable and valid measures. The substantive and varied data gathered from multiple methods including the collaborative work of an External Advisory Board, modified focus groups with staff and family caregivers, and structured cognitive interviews with health professionals were central in creating the revised version of the lucidity measure.

Beyond clinical outcomes: Case control study of the role of race in disruptive life events for people with serious mental illness

OBJECTIVE

To understand how race and serious mental illness (SMI) interact for disruptive life events defined as financial (bankruptcy and judgement filings), and non-financial (arrests).

METHODS

Patients were adults with schizophrenia (SCZ; N = 16,159) or bipolar I disorder (BPI; N = 30,008) matched 1:1 to patients without SMI (non-SMI) from health systems in Michigan and Southern California during 1/1/2007 through 12/31/2018. The main exposure was self-reported race, and the outcome was disruptive life events aggregated by Transunion. We hypothesized that Black patients with SCZ or BPI would be the most likely to experience a disruptive life event when compared to Black patients without SMI, and all White or Asian patients regardless of mental illness.

RESULTS

Black patients with SCZ had the least likelihood (37% lower) and Asian patients with BPI had the greatest likelihood (2.25 times higher) of experiencing a financial disruptive life event among all patients in the study. There was no interaction of race with either SCZ or BPI for experiencing an arrest. The findings did not support our hypotheses for patients with SCZ and partially supported them for patients with BPI.

CONCLUSIONS

Clinical initiatives to assess social determinants of health should consider a focus on Asian patients with BPI.

Psychometric Properties of Assessment Tools for Depression, Anxiety, Distress, and Psychological Problems in Breast Cancer Patients: A Systematic Review

OBJECTIVE

Various and accurate psychiatric assessments in patients with breast cancer who frequently suffer from psychological problems due to long-term survivors are warranted. This systematic review aimed to investigate the current evidence on psychometric properties of psychiatric assessment for evaluating psychological problems in breast cancer patients.

METHODS

This systematic review progressed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Four electronic databases such as Web of Science, PubMed, Embase, and Cumulative Index to Nursing and Allied Health Literature were searched. This study protocol was registered on Open Science Framework.

RESULTS

Of the 2,040 articles, 21 papers were finally included. Among them, only five studies showed the performance of psychiatric assessment tools. Among 13 assessment tools used in the selected articles, the Hospital Anxiety and Depression Scale (HADS), Distress Thermometer (DT), or Mini-Mental Adjustment to Cancer Scale was frequently used for the evaluation of psychological problems. The DT and Psychosocial Distress Questionnaire-Breast Cancer showed acceptable performances for the prediction of depression and anxiety assessed by the HADS.

CONCLUSION

This systematic review found psychiatric assessment tools with acceptable reliability and validity for breast cancer patients. However, comparative studies on reliability and validity of various scales are required to provide useful information for the selection of appropriate assessment tools based on the clinical settings and treatment stages of breast cancer. Joint research among the fields of psychiatry and breast surgery is needed for research to establish the convergent, concurrent, and predictive validity of psychiatric assessment tools in breast cancer patients.

Patient Experience with Their Health Care Provider Among Non-Pregnant Women of Childbearing Age with Diabetes Mellitus by Race and Ethnicity in the United States

Objectives

The study objective was to investigate differences in patient experiences with health care providers among non-pregnant women of childbearing age with diabetes mellitus (DM) by race/ethnicity.

Design

This study used cross-sectional data from the 2012-2018 Medical Expenditure Panel Survey. The sample was limited to women of childbearing age (18-45 years) who have ever been told they had diabetes (n = 763; weighted n = 903,670). The key independent variable was race/ethnicity. The variables of interest included patient experiences with health care in the past 12 months: patient-provider communication (PPC); patient-provider racial/ethnic concordance; patient-provider gender concordance; and satisfaction.

Results

After adjusting for age, marital status, education, poverty level, health insurance, and perceived health status, non-Hispanic (NH) Black women had lower odds (adjusted odds ratio [aOR] = 0.04; 95% confidence interval [CI] = 0.01-0.11) of receiving care from a health care provider of the same race compared with NH white women. Similar results were found among Hispanic and NH women of other or multiple races. Hispanic women had lower odds (aOR = 0.18; 95% CI = 0.06-0.50) of seeing a health care provider of the same race/ethnicity compared with NH white women in adjusted models. There were no statistically significant differences in PPC, patient-provider gender concordance, and satisfaction with their health care provider among Hispanic, NH Black, or NH women of other or multiple races in comparison to NH White women.

Conclusion

There is a need to improve PPC quality and satisfaction in this patient population. Patient-provider racial/ethnic discordance among women of color with DM is concerning given the existing diabetes-related disparities. More research on women with DM is needed to inform and improve patient experience and health outcomes.

Cognitive reserve attenuates the association between HIV serostatus and cognitive performance in adults living in the deep South

Cognitive reserve has shown evidence of mitigating HIV-related effects on cognition in people living with HIV (PWH). In a sample of adults residing in the Deep South, an underrepresented subgroup in the neuroAIDS literature, we assessed the association between HIV serostatus and age on processing speed, visual attention, executive function, and episodic memory and the attenuating effect of cognitive reserve. Adults (n = 138; 72 PWH; M age = 58.7 years, SD = 7.9 years; 75% nonwhite race) were recruited from a university clinic and the community. Verbal abilities served as a proxy for cognitive reserve. Regressions accounting for race, alcohol usage, and depressive symptoms were conducted for each cognitive outcome. Indirect effects were tested using the PROCESS macro. Being HIV seropositive was associated with worse executive function (b = -1.04, SE = 0.38, p = .007) and episodic memory (b = -39.94, SE = 12.54, p = .002) performance. Every year of age above the mean and nonwhite race was associated with worse cognitive performance (ps < .05). The addition of cognitive reserve to the model attenuated the HIV serostatus associations with executive function (BC 95% CI -0.770, -0.001) along with most associations between race and cognitive outcomes. Age associations remained for all cognitive outcomes (ps < .05). Findings highlight the importance of including verbal ability proxies of cognitive reserve when assessing cognition in PWH. Highlighting modifiable cognitive processes, such as cognitive reserve, will further the development of targeted cognitive interventions in this at-risk population.

Brief Adjustment Scale-6 for Measurement-Based Care: Psychometric Properties, Measurement Invariance, and Clinical Utility

The Brief Adjustment Scale-6 (BASE-6) was recently developed for measuring general psychological functioning within measurement-based care (MBC). The present study further evaluated psychometric properties, generalizability to race/ethnic populations, and clinical utility of the BASE-6. Three adult samples, Sample 1: online community participants (n = 394); Sample 2: college students (n = 249); Sample 3: outpatient clinic clients (n = 80), were included. The results demonstrated a high level of internal consistency, good test-retest reliability, and convergent validity in all samples. The unidimensional structure of BASE-6 was confirmed and factorial invariance was established across groups. Finally, the BASE-6 captured change over time by demonstrating a large effect size of pre-post treatment changes and significant linear change in multilevel growth modeling. These results support the BASE-6 as a reliable and valid measure regardless of race/ethnicity and can sensitively detect clinical change over the course of the treatment. Thus, the BASE-6 appears to accurately monitor overall psychological adjustment.

A general pattern of health erosion in the United States? An examination of self-reported health status from 1997 - 2018

Purpose

Recent research has found a general pattern of health erosion in self-assessed pain and allostatic load among adults in the United States (US). It remains to be determined if self-reported health status, hereafter SRH, also follows this pattern. The aim of this study was to examine whether a general pattern of health erosion is found in SRH among adults in the United States (US).

Methods

Data from the National Health Interview Survey 1997-2018 were used to study sex, educational attainment, and racial/ethnic patterns in SRH by age, period and cohort among adults in the US. The analytic sample consisted of respondents aged 18 years or older at the moment of interview with valid information in the age, sex, education, race/ethnicity and health status question (n = 669,501). Estimates for the percent population reporting poor/fair health were produced by age, period and cohort to study trends in health status by sex, educational attainment and race/ethnicity. All estimates were weighted to account for complex survey design.

Results

No discernible pattern of health erosion, or improvement, is observed in the age, period or cohort analyses of the percent of the population reporting poor/fair SRH by sex, educational attainment or race/ethnicity.

Conclusions

The analysis indicates that self-reported health does not follows the general pattern of health erosion found in self-assessed pain and allostatic load in the US. The percent of the population reporting poor/fair health status has remained relatively stable between 1997 and 2018. Further research is required to determine whether self-reported health is an appropriate metric to track population health in the US.

Validation and Revision of the Household Emergency Preparedness Instrument (HEPI) by a Pilot Study in the City University of New York

OBJECTIVE

The aim of this study was to pilot test the Household Emergency Preparedness Instrument (HEPI) with a diverse sample, allowing for assessment of reliability and validity of the instrument. The HEPI is an international, all-hazards questionnaire created to measure disaster preparedness of households, which results in data that can be used to enhance health promotion/disease prevention for individuals and promote resilience for communities.

METHODS

A cross-sectional study of faculty, staff, and students (N = 284) was completed to perform factor analysis to establish the HEPI's construct validity and compare preparedness across groups.

RESULTS

The factor analysis revealed 2 dimensions of general preparedness, explaining 35% of the sample variance (Cronbach's α = 0.89): preparedness actions and planning (α = 0.86) and disaster supplies and resources (α = 0.80). This factor analysis resulted in the revision of the subscaling of HEPI questions. Consistent with previous studies, faculty/staff, older age, higher income, and those with previous disaster experience were more prepared. The mean score was 15.28 out of 40 points.

CONCLUSIONS

The HEPI is easy to administer and explains an acceptable amount of variance. The reliability was strong in this assessment, particularly for a pilot test. Construct, criterion, face, and content validity support the adequacy of the HEPI to capture essentials of household emergency preparedness.

Cross-national harmonization of cognitive measures across HRS HCAP (USA) and LASI-DAD (India)

BACKGROUND

As global populations age, cross-national comparisons of cognitive health and dementia risk are increasingly valuable. It remains unclear, however, whether country-level differences in cognitive function are attributable to population differences or bias due to incommensurate measurement. To demonstrate an effective method for cross-national comparison studies, we aimed to statistically harmonize measures of episodic memory and language function across two population-based cohorts of older adults in the United States (HRS HCAP) and India (LASI-DAD).

METHODS

Data for 3,496 HRS HCAP (≥65 years) and 3,152 LASI-DAD (≥60 years) participants were statistically harmonized for episodic memory and language performance using confirmatory factor analysis (CFA) methods. Episodic memory and language factor variables were investigated for differential item functioning (DIF) and precision.

RESULTS

CFA models estimating episodic memory and language domains based on a priori adjudication of comparable items fit the data well. DIF analyses revealed that four out of ten episodic memory items and five out of twelve language items measured the underlying construct comparably across samples. DIF-modified episodic memory and language factor scores showed comparable patterns of precision across the range of the latent trait for each sample.

CONCLUSIONS

Harmonization of cognitive measures will facilitate future investigation of cross-national differences in cognitive performance and differential effects of risk factors, policies, and treatments, reducing study-level measurement and administrative influences. As international aging studies become more widely available, advanced statistical methods such as those described in this study will become increasingly central to making universal generalizations and drawing valid conclusions about cognitive aging of the global population.

The cultural equivalence of measurement in substance use research

Across a wide range of substance use outcomes, ethnic/racial minorities in the U.S. experience a disproportionately higher burden of negative health outcomes and/or lower levels of access to care (relative to non-Latinx White individuals). Various explanations for these substance use-related health disparities have been proposed. This narrative review will not focus on the theoretical content of these explanations but will instead focus on the underlying statistical frameworks that are used to test such theories. Here, we provide a narrative review of psychometric critiques of cross-cultural research, which collectively suggest that (a) research testing similarities and differences among ethnic/racial groups often miss or omit to test statistical assumptions of equal instrument functioning across the ethnic/racial groups being compared; (b) testing the assumptions of equal instrument functioning is feasible using established guidelines from modern measurement theories; and (c) substance use research may need to explicitly incorporate the tests of equal instrument functioning to prevent bias when making inferences across ethnic/racial groups. We provide recommendations for evaluating the cultural equivalence of measurement using structural equation modeling, and advocate that cross-cultural substance use research move toward statistical approaches that are better positioned to test for (and model) bias in measurement. Explicitly testing the cultural equivalence of measurement when making inferences across cultural groups (within a falsifiable psychometric framework) can advance our understanding of similarities and differences among ethnic/racial groups, and hence can provide a more socially just (and statistically robust) scientific base.

Health Literacy, Education, and Internal Consistency of Psychological Scales

Background:

Measurement error might lead to biased estimates, causing ineffective interventions and service delivery. Identifying measurement error of health-related instruments helps develop accurate assessment of health-related constructs.

Objective:

We compared the internal consistency of eight psychological scales used in health research in groups with adequate versus limited health literacy and in groups with higher versus lower education.

Methods:

Participants (N = 1,005) from a nationally representative internet panel completed eight self-report scales: (1) information avoidance, (2) cognitive causation, (3) unpredictability, (4) perceived severity, (5) time orientation, (6) internal health locus of control, (7) need for cognition, and (8) social desirability. The first four assess beliefs about diabetes and colon cancer. We used the Newest Vital Sign to categorize participants' health literacy (limited vs. adequate). We also categorized participants' education (high school or less vs. more than high school). We compared the Cronbach's alpha for each psychological scale between groups with different health literacy and education levels using the Feldt test.

Key Results:

Among all the 13 subscales, scale internal consistency was significantly lower among people with limited health literacy than those with adequate health literacy for five subscales: information avoidance for colon cancer (0.80 vs. 0.88), unpredictability of diabetes (0.84 vs. 0.88), perceived severity for diabetes (0.66 vs. 0.75), need for cognition (0.63 vs. 0.82), and social desirability (0.52 vs. 0.68). Internal consistency was significantly lower among people who had a high school education or less than among those with more than a high school education for four scales: perceived severity of diabetes (0.70 vs. 0.75), present orientation (0.60 vs. 0.66), need for cognition (0.73 vs. 0.80), and social desirability (0.61 vs. 0.70).

Conclusions:

Several psychological instruments demonstrated significantly lower internal consistency when used in a sample with limited health literacy or education. To advance health disparities research, we need to develop new scales with alternative conceptualizations of the constructs to produce a measure that is reliable among multiple populations. [HLRP: Health Literacy Research and Practice. 2021;5(3):e244–e255.]

Plain Language Summary:

We compared the internal consistency of several psychological scales in groups with adequate versus limited health literacy and higher versus lower education. For several scales, internal consistency was significantly lower among (1) people with limited health literacy compared those who have adequate health literacy and/or (2) people who had a high school education or less compared to those with more than a high school education.

Psychometric properties of the Fear of COVID-19 Scale amongst black South African university students

Coronavirus disease 2019 (COVID-19) has spread widely leading to a global public health crisis of a pandemic proportion. Whilst infection rates tend to fluctuate in South Africa, COVID-19 remains a life-threatening disease with the capacity to wreak fear and concern. The present study evaluated the psychometric qualities of the Fear of COVID-19 Scale (FCV-19S) amongst black South African university students (N = 433; Female: 58%; Mage = 23.51 [SD = 4.18]). The FCV-19S demonstrated a unidimensional factor structure and acceptable internal consistency (α = 0.87), Omega (ω = 0.88) and the greatest lower bound (GLB = 0.90) reliabilities. In addition, discriminant validity was demonstrated when FCV-19S items loaded separately from ordinary fear. The FCV-19S can be used as a measure of COVID-19-related fear amongst black South African university students.

Assessing the Predictive Validity of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) in Alaska Native and American Indian People

OBJECTIVES

The objective of this study was to examine the predictive validity of the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) among Alaska Native and American Indian (ANAI) people with an alcohol use disorder.

METHODS

The sample was 170 ANAI adults with an alcohol use disorder living in Anchorage, Alaska who were part of a larger alcohol intervention study. The primary outcome of this study was alcohol use as measured by mean urinary ethyl glucuronide (EtG). EtG urine tests were collected at baseline and then up to twice a week for four weeks. We conducted bivariate linear regression analyses to evaluate associations between mean EtG value and each of the three SOCRATES subscales (Recognition, Ambivalence, and Taking Steps) and other covariates such as demographic characteristics, alcohol use history, and chemical dependency service utilization. We then performed multivariable linear regression modeling to examine these associations after adjusting for covariates.

RESULTS

After adjusting for covariates, mean EtG values were negatively associated with the Taking Steps (P = 0.017) and Recognition (P = 0.005) subscales of the SOCRATES among ANAI people living in Alaska. We did not find an association between mean EtG values and the Ambivalence subscale (P = 0.129) of the SOCRATES after adjusting for covariates.

CONCLUSIONS

Higher scores on the Taking Steps and Recognition subscales of the SOCRATES at baseline among ANAI people predicted lower mean EtG values. This study has important implications for communities and clinicians who need tools to assist ANAI clients in initiating behavior changes related to alcohol use.

Communication About Medication by Providers-Adolescent and Young Adult Version: Confirmatory Factor Analyses

OBJECTIVE

To replicate the factor structure of a patient-report measure of provider communication about key medication prescription information, the Communication about Medication by Providers-Adolescent and Young Adult (CAMP-AYA) Version. We evaluated whether the 15-item, two-factor structure identified previously could be replicated via confirmatory factor analysis, and we also examined fit of unidimensional and bifactor models. Associations of CAMP-AYA Total and Factor Scores with provider satisfaction and select patient and medication characteristics were also examined.

METHODS

Participants were 739 AYA (ages 18-25) who completed the CAMP-AYA, a provider satisfaction rating, and provided demographic and medication information.

RESULTS

The bifactor model was best fitting (χ2 [75] = 689.60, p < .0001; root mean squared error of approximation = 0.11, 90% CI [0.10, 0.11]; Comparative Fit Index = 0.98; Tucker-Lewis Index = 0.98; Standardized Root Mean Square Residual Index = 0.02). Internal consistency reliabilities for Total and Factor Scores were high (αs > .89) and Total and Factor Scores were associated with provider satisfaction (ps < .001). CAMP-AYA scores varied as a function of type of prescription (short vs. long term; new vs. refill), with higher scores reported in the context of long term (>30-day course) or refilled prescriptions (ps < .007) in most cases.

CONCLUSIONS

This study provides additional support for the reliability of the CAMP-AYA as a tool to assess AYA perceptions of provider key information coverage about medication prescriptions.

Moving urologic disparities research from evidence synthesis to translational research: a dynamic, multidisciplinary approach to tackling inequalities in urology

Disparities in urology are well-documented but less is known about the role of translational research within existing interventional models to address inequalities. In this narrative review, we utilize an accepted framework of the process of translational research in mitigating disparities to investigate current translational and interventional urologic programs that bridge the gap. Three established, disparity-focused urologic interventional programs were identified and are highlighted in depth. Finally, we extrapolate from these findings to provide 10 policy relevant implications to help move urologic disparities research from evidence synthesis to translational research.

The Roles of Body Composition and Specific Strength in the Relationship Between Race and Physical Performance in Older Adults

BACKGROUND

Socioeconomics may explain black-white differences in physical performance; few studies examine racial differences among socioeconomically similar groups. Performance is also affected by body composition and specific strength, which differ by race. We assessed whether racial differences in physical performance exist among older adults with high education and similar income and whether body composition and specific strength attenuate observed differences.

METHODS

Cross-sectional analysis of 536 men (18% black) and 576 women (28% black) aged more than 60 years from the Baltimore Longitudinal Study of Aging. Body composition was evaluated using dual-energy x-ray absorptiometry. Specific strength was assessed by quadricep peak torque divided by height-normalized thigh cross-sectional area and grip strength divided by body mass index-normalized appendicular lean mass. Physical performance was assessed using usual gait speed and fast 400 m walk time. Sex-stratified linear regression models, adjusted for age, height, education, and recent income, determined whether body composition or specific strength attenuated associations between race and physical performance.

RESULTS

Blacks were younger, with higher weight and appendicular lean mass. Black women had higher percent fat and specific strength. In both sexes, blacks had poorer physical performance after adjustment for socioeconomic factors. In women, neither body composition nor specific strength altered the association with gait speed. In men, neither body composition nor specific strength attenuated racial differences in either performance measure.

CONCLUSIONS

Poorer physical performance among black compared to white older adults persists among persons with high education and similar income and cannot generally be attributed to differences in body composition or specific strength.

Measurement Invariance of Screening Measures of Anxiety, Depression, and Level of Functioning in a US Sample of Minority Older Adults Assessed in Four Languages

Population aging in the US and its increase in racial/ethnic diversity has resulted in a growing body of literature aimed at measuring health disparities among minority older adults. Disparities in health outcomes are often evaluated using self-reported measures and, to attend to linguistic diversity, these measures are increasingly being used in languages for which they were not originally developed and validated. However, observed differences in self-reported measures cannot be used to infer disparities in theoretical attributes, such as late-life depression, unless there is evidence that individuals from different groups responded similarly to the measures-a property known as measurement invariance. Using data from the Positive Minds-Strong Bodies randomized controlled trial, which delivered evidence-based mental health and disability prevention services to a racially/ethnically diverse sample of minority older adults, we applied invariance tests to two common measures of anxiety and depression (the GAD-7 and the HSCL-25) and two measures of level of functioning (the Late-Life FDI and the WHODAS 2.0) comparing four different languages: English, Spanish, Mandarin, and Cantonese. We found that these measures were conceptualized similarly across languages. However, at the item-level symptom burden, we identified a non-negligible number of symptoms with some degree of differential item functioning. Spanish speakers reported more worry symptoms and less somatic symptoms for reasons unrelated to their psychological distress. Mandarin speakers reported more feelings of restlessness, and both Mandarin and Cantonese speakers reported no interest in things more often for reasons unrelated to their psychological distress. Mandarin and Cantonese speakers were also found to consistently report more difficulties performing physical activities for reasons unrelated to their level of functioning. In general, invariance tests have been insufficiently applied within psychological research, but they are particularly relevant as a prerequisite to accurately measure health disparities. Our results highlight the importance of conducting invariance testing, as we singled out several items that may require careful examination before considering their use to compare symptoms of psychological distress and level of functioning among ethnically and linguistically diverse older adult populations.

Relationships between parent and adolescent/young adult mental health among Hispanic and non-Hispanic childhood cancer survivors

PURPOSE

To examine associations between parents and adolescent and young adult (AYA) childhood cancer survivors' (CCS) mental health, and differences by Hispanic ethnicity.

SAMPLE

Participants were 129 CCS (Mage = 19.5 yrs.; 49.9% female) and their parents (Mage = 49.0 yrs.; 87.6% female); 52.7% identified as Hispanic.

METHODS

CCS completed assessments of Depressive Symptoms (CES-D), Posttraumatic Growth (PTG) and Pediatric Quality of Life (PedsQL), while parents completed CES-D, Perceived Stress (PSS) and Posttraumatic Stress Disorder (PTSD) measures.

RESULTS

After controlling for covariates, all three negative parental mental health measures (Parent CES-D, PSS, and PTSD), were positively associated with CCS CES-D indicating that higher depressive symptoms and stress in parents was associated with higher depressive symptoms in CCS. Parent CES-D was negatively associated with CCS PedsQL and parent PSS was negatively associated with CCS PTG. Moderation analysis revealed parent PSS to be negatively associated with PedsQL and positively related to CES-D among Hispanic families only.

CONCLUSION

Higher parental negative mental health measures may adversely affect CCS levels of depression, while lower values for parental negative health measures were associated with positive CCS mental health outcomes in AYA. Hispanic parents experience more associations with stress than non-Hispanics.

IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS

Long-term survivorship follow-up care guidelines should address the mental health needs of both parents and CCS, paying particular attention to perceived stress in Hispanic families.

Tools to Measure Health Literacy among US African Americans and Hispanics/Latinos with Type 2 Diabetes: A Scoping Review of the Literature

OBJECTIVE

To provide an overview of the health literacy tools that have been validated in samples of African Americans and Hispanics/Latinos with type 2 diabetes, growing segments of the US population.

METHODS

Following PRISMA guidelines, three electronic databases were searched. The following inclusion criteria were used: peer-reviewed research; examined validity of a health literacy tool; and included US African American and/or Hispanic/Latino adults with type 2 diabetes.

RESULTS

Sixteen studies were selected; none exclusively included African Americans while 3 exclusively included Hispanics/Latinos in the sample. Seventeen health literacy tools were identified. Among African Americans, 2 health literacy screeners, 2 diabetes knowledge, and 3 numeracy tools have been validated. Among Hispanics/Latinos, 1 health literacy screener, 1 diabetes knowledge, and 1 numeracy tool have been validated. However, cross-cultural adaptation principles were rarely considered in the development and validation of these tools.

CONCLUSION

In those with type 2 diabetes, future studies should investigate the validity of health literacy screeners among English-speaking Hispanics/Latinos and general health literacy tools among African Americans and Hispanics/Latinos. Evidence on the validity of diabetes knowledge and numeracy tools was mixed across studies.

PRACTICE IMPLICATIONS

Findings can inform the selection of culturally-appropriate health literacy tools in clinical and research settings.

DIF in the Spanish Version of the Verbal Selective Reminding Test Using Samples From Hispanics in the United States, Mexicans, and Spaniards

Aim

Before a test can be used in the target population, it is necessary to demonstrate that there is measurement equivalence. One way to do this is by studying differential item functioning (DIF).

Objective

In this study, we used the Mantel-Haenszel procedure and logistic regression to analyze DIF in the Spanish version of the Verbal Selective Reminding Test between Spaniards, Mexicans, and Hispanics in the United States.

Method

Three balanced samples, matched by age, education, and sex, were studied: Spaniards, Mexicans, and Hispanics [616 healthy participants from Spain (n = 211), Mexico (n = 201), and the United States (n = 205)]. A six-trial version of the Spanish version of the Verbal Selective Reminding Test was administered and scored according to standard procedures.

Results

Statistical analysis showed some DIF between the samples of Spaniards, Mexicans, and Hispanics. A bootstrap validation of results confirmed that the item pollo showed DIF: the Mexicans and Hispanics outperformed the Spaniards, holding a total score constant. The item oído also showed DIF and was remembered in greater measure by the Spaniards.

Conclusion

The Spanish version of the Verbal Selective Reminding Test can be used with Hispanic populations.

Using the Trauma Symptom Checklist for Children-Short form (TSCC-SF) on abused children in South Africa: Confirmatory factor analysis and Rasch models

BACKGROUND

While assessment measures of trauma-related symptoms in children exist, few of them are at once brief, self-reports, normed, comprehensive (i.e., cover both general and trauma-specific symptoms), and thus suitable for poorly resourced clinical contexts.

OBJECTIVE

This study validated the short form of the Trauma Symptom Checklist for Children (TSCC-SF) in a sample of children and adolescents.

PARTICIPANTS AND SETTINGS

Participants were school-age children and adolescents (N = 270; M_age = 12.55 yrs., SD = 1.19; 67% = Female) exposed to different types of abuse (i.e., sexual, physical, emotional and neglect) receiving counselling at a non-governmental organisation.

METHODS

The TSCC-SF's factor structure and Differential Item Functioning (DIF) across sexes were examined using confirmatory factor analysis and Rasch analysis.

RESULTS

Results revealed a satisfactory construct validity of the scale, while internal consistency was also adequate. No DIF was found across the sexes.

CONCLUSIONS

The TSCC-SF appears to be a viable option for use with children exposed to different types of abuse, particularly in low resource clinical contexts.

Culturally Sensitive OCD Research: Lessons from the U.S.-Mexico Border

This paper explores culturally-related concerns that arose during a multi-year study of obsessive-compulsive disorder (OCD) along the U.S.-Mexico border and describes adaptations made to better connect the research process to study participants. The purpose of this exploration is two-fold: (1) to offer suggestions for culturally sensitive borderland mental health research; and (2) to enhance dialog focused on culture, mental health research and the U.S.-Mexico border. Systematic coding of the written record of weekly research team meetings identified six recurring cultural concerns: emotionally charged and poorly understood terminology; differing meanings of ethnicity and acculturation; quality of life-regional variation and uncertainty; overlap of research and care; hopeful but hesitant; and fatalism. We conclude that diligence in the initial planning phase of a study is only part of the challenge in doing culturally sensitive research. Equally important is an ongoing process of evaluation to make explicit cultural concerns that arise during research, as well as a readiness to implement culturally sensitive research adaptations.

Predictive validity of the SOCRATES in a clinical sample of Latina/o adolescents

The Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES) is a widely used measure of a client's motivation to change their substance use behavior. It is comprised of 3 subscales, recognition, ambivalence, and taking steps, which correspond to one's awareness, uncertainty, and behavior relative to their substance use. Typically the measure has been examined in adult treatment samples, whereas less attention has been paid to its use with adolescents, especially racial/ethnic minority youth. The purpose of the current study was to test the predictive validity of the SOCRATES subscales on posttreatment substance use levels with a clinical sample of Latina/o adolescents (N = 105) in substance use treatment. Hypotheses were tested via generalized linear models for each of the 3 subscales. Results indicated that higher scores on the Taking Steps subscale of the SOCRATES at pretreatment were predictive of lower days of substance use after treatment for adolescents in the sample. Implications of the results and suggestions for future research are discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Development and Spanish translation of the Weinberg Center Risk and Abuse Prevention Screen (WC-RAPS)

Barriers for enhanced detection, identification, and reporting of elder abuse include the paucity of appropriate, valid, easily administered screening tools. This article describes the qualitative methods used in the development of the Weinberg Center Risk and Abuse Prevention Screen (WC-RAPS), and of its Spanish version. Focus groups and cognitive interviews were instrumental in identifying problematic items, underscoring potential response errors, and informing about putative causes for divergent interpretations of item-intent. Seven of the 11 original items were modified, a double-barreled item was segregated into two, one item deleted, and three additional items included to create the final 13 WC-RAPS items. The multi-step approach implemented for the Spanish conversion evidenced deviation from the original intended meaning for one item. The readability for English and Spanish versions was also assessed. Screening for elder abuse, if implemented systematically can be instrumental in identifying unrecognized abuse and preventing reoccurrence.

Measurement equivalence: a glossary for comparative population health research

Comparative population health studies are becoming more common and are advancing solutions to crucial public health problems, but decades-old measurement equivalence issues remain without a common vocabulary to identify and address the biases that contribute to non-equivalence. This glossary defines sources of measurement non-equivalence. While drawing examples from both within-country and between-country studies, this glossary also defines methods of harmonisation and elucidates the unique opportunities in addition to the unique challenges of particular harmonisation methods. Its primary objective is to enable population health researchers to more clearly articulate their measurement assumptions and the implications of their findings for policy. It is also intended to provide scholars and policymakers across multiple areas of inquiry with tools to evaluate comparative research and thus contribute to urgent debates on how to ameliorate growing health disparities within and between countries.

Breaking down the monolith: Understanding flu vaccine uptake among African Americans

Black adults are significantly less likely to be immunized for seasonal influenza when compared to Whites. This persistent disparity contributes to increased influenza-related morbidity and mortality in the African American population. Most scholarship on vaccine disparities has compared Whites and Blacks. Employing Public Health Critical Race Praxis, this study seeks to shift the focus to explore differences within the Black population. Utilizing a nationally-representative 2015 survey of US Black adults (n = 806), we explore differences by gender, age, income, and education across vaccine-related measures (e.g., perceived risk, knowledge, attitudes) and racial factors (e.g. racial salience, racial fairness, perceived discrimination). We also explore differences by vaccine behavior in the past five years among those who vaccinate every year, most years but not all, once or twice, and never. Greater frequency of flu vaccine uptake was associated with better self-reported vaccine knowledge, more positive vaccine attitudes, more trust in the flu vaccine and the vaccine process, higher perceived disease risk, lower perceived risk of vaccine side effects, stronger subjective and moral norms, lower general vaccine hesitancy, higher confidence in the flu vaccine, and lower perceived barriers. Logistic regression results highlighted other significant differences among the groups, emphasizing areas to target for improved vaccination rates. We find great diversity within the Black community related to influenza immunization decisions, highlighting the need to “break down the monolith” in future research.

•

Empirically tested differences within the Black population for flu vaccine behavior.

•

Detected significant differences in past vaccine behavior by age, gender, income, and education.

•

Focus on past behavior to move adults along the continuum to increase vaccination.

•

Highlights diversity within the Black population, often missing from comparative studies.

Identifying Unbiased Items for Screening Preschoolers for Disruptive Behavior Problems

Objective

Efficient identification and referral to behavioral services are crucial in addressing early-onset disruptive behavior problems. Existing screening instruments for preschoolers are not ideal for pediatric primary care settings serving diverse populations. Eighteen candidate items for a new brief screening instrument were examined to identify those exhibiting measurement bias (i.e., differential item functioning, DIF) by child characteristics.

Method

Parents/guardians of preschool-aged children ( N = 900) from four primary care settings completed two full-length behavioral rating scales. Items measuring disruptive behavior problems were tested for DIF by child race, sex, and socioeconomic status using two approaches: item response theory-based likelihood ratio tests and ordinal logistic regression.

Results

Of 18 items, eight were identified with statistically significant DIF by at least one method.

Conclusions

The bias observed in 8 of 18 items made them undesirable for screening diverse populations of children. These items were excluded from the new brief screening tool.

Measurement properties of the Center for Epidemiologic Studies Depression Scale (CES-D 10): Findings from HCHS/SOL

The Center for Epidemiologic Studies Depression Scale (CES-D) is a widely used self-report measure of depression symptomatology. This study evaluated the reliability, validity, and measurement invariance of the CES-D 10 in a diverse cohort of Hispanics/Latinos from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). The sample consisted of 16,415 Hispanic/Latino adults recruited from 4 field centers (Miami, FL; San Diego, CA; Bronx, NY; Chicago, IL). Participants completed interview administered measures in English or Spanish. The CES-D 10 was examined for internal consistency, test-retest reliability, convergent validity, and measurement invariance. The total score for the CES-D 10 displayed acceptable internal consistencies (Cronbach's alpha's = .80-.86) and test-retest reliability (r values = .41-.70) across the total sample, language group and ethnic background group. The total CES-D 10 scores correlated in a theoretically consistent manner with the Spielberger State-Trait Anxiety Inventory, r = .72, p < .001, the Patient Health Questionnaire-9 depression measure, r = .80, p < .001, the Short Form-12's Mental Component Summary, r = -.65, p < .001, and Physical Component Summary score, r = -.25, p < .001. A confirmatory factor analysis showed that a 1-factor model fit the CES-D 10 data well (CFI = .986, RMSEA = .047) after correlating 1 pair of item residual variances. Multiple group analyses showed the 1-factor structure to be invariant across English and Spanish speaking responders and partially invariant across Hispanic/Latino background groups. The total score of the CES-D 10 can be recommended for use with Hispanics/Latinos in English and Spanish. (PsycINFO Database Record

Using Qualitative Methods to Assess the Conceptual Equivalence of the Spanish and English Stroke Action Test (STAT)

Members of racial/ethnic minorities, in contrast to majority groups, experience disparities in stroke risk factors, recognition, evaluation, and treatment. This article describes the use of qualitative methods to examine the cultural and lifestyle appropriateness, clarity of item-wording, comprehension of item intent, and conceptual equivalence of the developed Spanish and the revised English Stroke Action Test (which includes three additional atypical stroke symptoms more common in women). Thirty in-depth cognitive interviews were conducted (10 in Spanish) using concurrent structured probes. The desired ultimate outcome was to obtain conceptually equivalent measures in both languages. Four sources of variability in comprehension were identified: unfamiliar and/or idiosyncratic Spanish words used in translation; phrases in the original (English) and in the literal (Spanish) translation that were not understood; and unclear intended meaning of the original (English) items. Cognitive interviews helped identify problematic items, highlighted potential response errors, and provided insight regarding putative causes for inconsistent interpretation.

Systematic review of dementia prevalence and incidence in United States race/ethnic populations

OBJECTIVE

To identify incidence and prevalence of dementia in racial and ethnic populations in the United States.

METHODS

A systematic review of literature.

RESULTS

A total of 1215 studies were reviewed; 114 were included. Dementia prevalence rates reported for age 65+ years from a low of 6.3% in Japanese Americans, 12.9% in Caribbean Hispanic Americans, 12.2% in Guamanian Chamorro and ranged widely in African Americans from 7.2% to 20.9%. Dementia annual incidence for African American (mean = 2.6%; SD = 1%; range, 1.4%-5.5%) and Caribbean Hispanic populations were significantly higher (mean, 3.6%; SD, 1.2%; range, 2.3%-5.3%) than Mexican American and Japanese Americans and non-Latino white populations (0.8%-2.7%), P < .001.

CONCLUSIONS

Data are needed for American Indian, most Asian, and Pacific Islander populations. Disaggregation of large race/ethnic classifications is warranted due to within-population heterogeneity in incidence and prevalence. African American and Caribbean Hispanic studies showed higher incidence of dementia. A nationwide approach is needed to identify communities at high risk and to tailor culturally appropriate services accordingly.

Development and psychometric evaluation of a condom use self-efficacy measure in Spanish and English

BACKGROUND

Condom self-efficacy is an important construct for HIV/STI prevention and intervention. A psychometrically sound measure of the self-efficacy for using condoms that has been designed for Hispanic women to respond in Spanish or English is needed.

OBJECTIVES

The goal of this study was to develop and evaluate a brief self-report measure of condom use self-efficacy.

METHODS

We developed a 15-item measure of condom use self-efficacy based on expert knowledge of measurement and HIV/STI prevention with Hispanic women using a translation-back translation approach. Participants were 320 Hispanic women from the Southeastern US.

RESULTS

Internal consistency of the full measure was 92. A short form of the instrument with a subset of five items also had acceptable internal consistency, alpha = .80, and was significantly correlated with the full scale, rs = .93, p < .001. A single latent factor explained 9-48% of the variation in these items. Evidence of construct validity of the short form was provided by correlations of the scale with two self-report measures of condom use: rs = .34** with condom use, rs = .37** with condom use during vaginal sex.

CONCLUSIONS

Either the full measure or the five-item measure could be used in studies where condom use is an important behavioral outcome, such as evaluating prevention interventions, with Hispanic women. Future studies should examine the performance of this measure with other groups, including Hispanic men and members of other ethnic and language groups.

Bringing Community and Academic Scholars Together to Facilitate and Conduct Authentic Community Based Participatory Research: Project UNITED

Cultural competency, trust, and research literacy can affect the planning and implementation of sustainable community-based participatory research (CBPR). The purpose of this manuscript is to highlight: (1) the development of a CBPR pilot grant request for application; and (2) a comprehensive program supporting CBPR obesity-related grant proposals facilitated by activities designed to promote scholarly collaborations between academic researchers and the community. After a competitive application process, academic researchers and non-academic community leaders were selected to participate in activities where the final culminating project was the submission of a collaborative obesity-related CBPR grant application. Teams were comprised of a mix of academic researchers and non-academic community leaders, and each team submitted an application addressing obesity-disparities among rural predominantly African American communities in the US Deep South. Among four collaborative teams, three (75%) successfully submitted a grant application to fund an intervention addressing rural and minority obesity disparities. Among the three submitted grant applications, one was successfully funded by an internal CBPR grant, and another was funded by an institutional seed funding grant. Preliminary findings suggest that the collaborative activities were successful in developing productive scholarly relationships between researchers and community leaders. Future research will seek to understand the full-context of our findings.

Psychobiobehavioral Model for Preterm Birth in Pregnant Women in Low- and Middle-Income Countries

Preterm birth (PTB) is a final common outcome resulting from many interrelated etiological pathways; of particular interest is antenatal psychosocial distress (i.e., stress, anxiety, and depression). In LMI countries, both exposure to severe life stressors and rate of PTB are on average greater when compared with high-income countries. In LMI countries women are exposed to some of the most extreme psychosocial stress worldwide (e.g., absolute poverty, limited social resources). High prevalence of antenatal stress and depression have been observed in some studies from LMI countries. We propose a psychosocial, biological, and behavioral model for investigating the complex multisystem interactions in stress responses leading to PTB and explain the basis of this approach. We discuss ethical considerations for a psychosocial, biological, and behavioral screening tool to predict PTB from a LMI country perspective.

Evaluating the reliability of the Attitudes to Randomized Trial Questionnaire (ARTQ) in a predominantly African American sample

Purpose

To evaluate the reliability of the Attitudes to Randomized Trial Questionnaire (ARTQ) in measuring perceptions of cancer clinical trials in a predominantly African American (AA) sample in South Carolina (SC).

Methods

Principal Component Analysis (PCA) and Cronbach’s alpha estimates were used to assess the reliability of the ARTQ in a convenience sample of 315 participants (81.4 % AA) who were recruited from 2008 to 2013, and who live in eleven different counties in South Carolina with high rates of racial disparities in cancer mortality rates.

Results

Slightly more than half of the 315 participants had at least a college education (77.9 %), 84.8 % were female, and 53.1 % had an annual income of $40,000 or more. In this study, PCA confirmed that the ARTQ is unidimensional. Cronbach’s alpha for the ARTQ was 0.86.

Conclusion

The ARTQ displayed strong evidence of high statistical reliability. This analysis has great implications for future research because it represents the first test of reliability of the ARTQ in a predominantly African American sample and lays the groundwork for use of the ARTQ in future studies in diverse populations.

Measurement Invariance of the Short Inventory of Problems-Revised Across African American and Non-Latino White Substance Users

This study investigated measurement invariance properties of the Short Inventory of Problems - Revised (SIP-R) across racial groups. The sample included 195 African American and 194 non-Latino White adult participants in a clinical trial investigating the effectiveness of motivational enhancement therapy in the National Institute on Drug Abuse Clinical Trials Network. The SIP-R demonstrated configural invariance and weak metric invariance, suggesting conceptualizations of adverse consequences of substance use are equivalent across racial groups. The SIP-R also indicated partial strong/scalar and strict metric invariance, suggesting a need for continued research of SIP-R items to ensure valid measurement and outcomes across racial groups.

Psychometric properties and confirmatory factor analysis of the CASP-19, a measure of quality of life in early old age: the HAPIEE study

OBJECTIVES

The aim was to assess the reliability and validity of the quality of life (QoL) instrument CASP-19, and three shorter versions of CASP-12 in large population sample of older adults from the HAPIEE (Health, Alcohol, and Psychosocial factors In Eastern Europe) study.

METHODS

From the Czech Republic, Russia, and Poland, 13,210 HAPIEE participants aged 50 or older completed the retirement questionnaire including CASP-19 at baseline. Three shorter 12-item versions were also derived from original 19-item instrument. Psychometric validation used confirmatory factor analysis, Cronbach's alpha, Pearson's correlation, and construct validity.

RESULTS

The second-order four-factor model of CASP-19 did not provide a good fit to the data. Two-factor CASP-12v.3 including residual covariances for negative items to account for the method effect of negative items had the best fit to the data in all countries (CFI = 0.98, TLI = 0.97, RMSEA = 0.05, and WRMR = 1.65 in the Czech Republic; 0.96, 0.94, 0.07, and 2.70 in Poland; and 0.93, 0.90, 0.08, and 3.04 in Russia). Goodness-of-fit indices for the two-factor structure were substantially better than second-order models.

CONCLUSIONS

This large population-based study is the first validation study of CASP scale in Central and Eastern Europe (CEE), which includes a general population sample in Russia, Poland, and the Czech Republic. The results of this study have demonstrated that the CASP-12v.3 is a valid and reliable tool for assessing QoL among adults aged 50 years or older. This version of CASP is recommended for use in future studies investigating QoL in the CEE populations.

Race Differences: Use of Walking Speed to Identify Community-Dwelling Women at Risk for Poor Health Outcomes--Osteoarthritis Initiative Study

BACKGROUND

Onset of disability, risk for future falls, frailty, functional decline, and mortality are strongly associated with a walking speed of less than 1.0 m/s.

OBJECTIVE

The study objective was to determine whether there were differences in slow walking speed (<1.0 m/s) between community-dwelling African American and white American adult women with osteoarthritis symptoms. An additional aim was to examine whether racial differences in walking speed can be attributed to age, obesity, socioeconomic factors, disease severity, or comorbidities.

DESIGN

A cross-sectional design was used.

METHODS

Community-dwelling adults were recruited from Baltimore, Maryland; Columbus, Ohio; Pittsburgh, Pennsylvania; and Pawtucket, Rhode Island. Participants were 2,648 women (23% African American) who were 45 to 79 years of age and had a self-selected baseline walking speed of 20 m/s in the Osteoarthritis Initiative Study. Mixed-effects logistic regression models were used to examine racial differences in walking speed (<1.0 m/s versus ≥1.0 m/s), with adjustments for demographic factors, socioeconomic factors, disease severity, and comorbidities.

RESULTS

Walking speed was significantly slower for African American women than for white American women (mean walking speed=1.19 and 1.33 m/s, respectively). The prevalence of a walking speed of less than 1.0 m/s in this cohort of middle-aged women was 9%; about 50% of the women with a walking speed of less than 1.0 m/s were younger than 65 years. Women with a walking speed of less than 1.0 m/s had lower values for socioeconomic factors, higher values for disease severity, and higher prevalences of obesity and comorbidities than those with a walking speed of ≥1.0 m/s. After controlling for these covariates, it was found that African American women were 3 times (odds ratio=2.9; 95% confidence interval=2.0, 4.1) more likely to have a walking speed of less than 1.0 m/s than white American women.

LIMITATIONS

The study design made it impossible to know whether a walking speed of less than 1.0 m/s in women who were 45 years of age or older was a predictor of future poor health outcomes.

CONCLUSIONS

In this study, race was independently associated with a walking speed of less than 1.0 m/s in community-dwelling women who had or were at risk for osteoarthritis, with African American women having 3 times the risk for slow walking as white American women. This finding suggests that middle-aged African American women have an increased risk for poor health outcomes. Further longitudinal evaluations are needed to confirm the long-term health outcomes in a middle-aged population and to establish walking speed as a useful tool for identifying middle-aged women at high risk for poor health outcomes.

Confronting inequities: A scoping review of the literature on pharmacist practice and health-related disparities

BACKGROUND

An expanding body of literature is exploring the presence and impact of health and health care disparities among marginalized populations. This research challenges policy makers, health professionals, and scholars to examine how unjust and avoidable inequities are created at the societal, institutional, and individual level, and explore strategies for mitigating challenges.

OBJECTIVES

Recognizing the significance of this broader conversation, this scoping review provides an overview of pharmacy-specific research attentive to health-related disparities.

METHODS

Following Arksey and O'Malley's framework, a rigorous screening process yielded 93 peer-reviewed and 23 grey literature articles, each analyzed for core themes.

RESULTS

Lending critical insight to how pharmacy practice researchers are conceptualizing and measuring health inequities, this review highlights three paths of inquiry evident across this literature, including research focused on what pharmacists know about marginalized groups, how pharmacists perceive these groups, and how they provide services. Striving to drive research and practice forward, this review details research gaps and opportunities, including a need to expand the scope of research and integrate knowledge.

CONCLUSIONS

As pharmacists endeavor to provide equitable and impactful patient care, it is essential to understand challenges, and build strong evidence for meaningful action.

Advancing research on racial-ethnic health disparities: improving measurement equivalence in studies with diverse samples

To conduct meaningful, epidemiologic research on racial-ethnic health disparities, racial-ethnic samples must be rendered equivalent on other social status and contextual variables via statistical controls of those extraneous factors. The racial-ethnic groups must also be equally familiar with and have similar responses to the methods and measures used to collect health data, must have equal opportunity to participate in the research, and must be equally representative of their respective populations. In the absence of such measurement equivalence, studies of racial-ethnic health disparities are confounded by a plethora of unmeasured, uncontrolled correlates of race-ethnicity. Those correlates render the samples, methods, and measures incomparable across racial-ethnic groups, and diminish the ability to attribute health differences discovered to race-ethnicity vs. to its correlates. This paper reviews the non-equivalent yet normative samples, methodologies and measures used in epidemiologic studies of racial-ethnic health disparities, and provides concrete suggestions for improving sample, method, and scalar measurement equivalence.

Contextually appropriate measurement as the basis for culturally appropriate interventions: a case study in Managua, Nicaragua

Despite recent advances in U.S. health care, racial and ethnic minorities experience significantly worse health and mental health outcomes. Policy responses to this problem are based on available research, which is often premised on a misinterpretation of the cultural concepts that underlie people's health and mental health. Health researchers often rely upon measurements with questionable cultural validity. This contributes to a lack of understanding of health disparities that nondominant populations experience and creates obstacles to the development of effective policies to alleviate them. Even statistically valid or literally translated measurements often fail to account for different social and cultural contexts and/or neglect to consider vital information about the population studied or its history. This article reports on the content validity of measures used in a study that investigated predictors of mental health in Managua, Nicaragua. Results reveal a polarized response structure and lack of cultural relevance in underlying concepts measured.
