Community events as viable sites for recruiting minority volunteers who agree to be contacted for future research

Factors affecting the recruitment of Hispanic/Latinx American older adults in clinical trials in the United States: A scoping review

OBJECTIVE

Participation of Hispanic/Latinx American older adults (HLAOA) in clinical trials is fundamental to health equity in aging research. However, information on strategies for the successful recruitment of this population in clinical trials is limited.

DESIGN

This scoping review aims to identify hindering and facilitating factors that impact the recruitment of HLAOA in clinical trials in the United States.

METHODS

Two databases (PubMed, EMBASE) were searched for original research articles from inception until March 2022 reporting on factors that engaged HLAoa (≥65) in clinical trials. One thousand and thirteen studies were scrutinized to identify 31 eligible articles.

RESULTS

Most articles were from cancer clinical trials (14 studies). Hindering factors that impacted the recruitment of HLAoa in clinical trials were related to (i) study design and logistics challenges, (ii) challenges imposed by social determinants of health, (iii) communication barriers, and (iv) patients' mistrust, and (v) family issues. Facilitating factors include (i) effective modes of outreach, (ii) strategic clinical trial design, (iii) incorporating culturally-respectful approaches that are tailored to the participants' sociocultural background, and (iv) bridging language barriers.

CONCLUSIONS

Successful recruitment of HLAOA into clinical trials requires identifying the study question, co-designing the trial design, implementation, and evaluation in respectful collaboration with the Hispanic/Latinx community with careful attention to their needs and minimizing the study burden on this vulnerable population. Factors identified here may guide researchers to better understand the needs of HLAOA and successfully recruit them into clinical trials, leading to more equitable research that increases their representation in clinical research.

Setting and motivation in the decision to participate: An approach to the engagement of diverse samples in mobile research

Internet and mobile based research are powerful tools in the creation of large, cohort studies (eCohort). However, recent analysis indicates that an underrepresentation of minority and low income groups in these studies might exceed that found in traditional research [1-5]. In this report, we present findings from an experiment in research engagement using the Eureka Research Platform developed to enroll diverse populations in support of biomedical clinical research. This experiment involved the recruitment of African American and Latino participants in a smartphone based survey at a temporary, charitable, dental event sponsored, in part, by the research team, in order to explore the impact of setting and approach on recruitment outcomes. 211 participants enrolled including a significant representation of African Americans (51%) and Latinos (31%) and those with education levels at high school or less (37%). Interviews conducted after the study confirmed that our recruitment efforts within the context of a service event affected the decision to participate. While further research is necessary, this experiment holds promise for the engagement of underrepresented groups in research.

Bridging the Gap: Racial concordance as a strategy to increase African American participation in breast cancer research

Lack of African American females in breast cancer research has been receiving substantial attention. This study seeks to identify research perceptions and motivating factors needed to increase racial/ethnic minority participation in breast cancer research. A total of 57 African American women (Σ = 47.8 years), from Rhode Island and Texas, completed a questionnaire and focus group. While many participants were not breast cancer survivors, they reported knowledge of their racial group’s risk for breast cancer. One major finding that could be seen as both a facilitator and barrier is racial concordance between participant and researcher. Cultural sensitivity and trust building is recommended to increase minority participation.

Association of Race, Ethnicity and Language with Participation in Mental Health Research Among Adult Patients in Primary Care

Racial and ethnic minorities remain underrepresented in clinical psychiatric research, but the reasons are not fully understood and may vary widely between minority groups. We used the Z-test of independent proportions and binary logistic regression to examine the relationship between race, ethnicity or primary language and participation in screening as well as interest in further research participation among primary care patients being screened for a depression study. Minorities were less likely than non-Hispanic Whites to complete the initial screening survey. Latinos and Blacks were more likely to agree to be contacted for research than non-Hispanic Whites. Among Latinos, primary language was associated with willingness to be contacted for research. Associations between research participation and race, ethnicity and language are complex and vary across different enrollment steps. Future research should consider stages of the research enrollment process separately to better understand barriers and identify targets for intervention.

Promoting Retention: African American Older Adults in a Research Volunteer Registry

Objectives: The objectives of this study were to evaluate the capability of a research volunteer registry to retain community-dwelling African American older adults, and to explore demographic and health factors associated with retention. Method: A logistic regression model was used to determine the influence of demographics, health factors, and registry logic model activities on retention in a sample of 1,730 older African American adults. Results: Almost 80% of participants active in the volunteer research registry between January 2012 and June 2015 were retained. Employment, being referred to research studies, a higher number of medical conditions, and more follow-up contacts were associated with an increased likelihood of retention. Older age, more months in the registry, and more mobility problems decreased the likelihood of retention. Discussion: These results suggest the Michigan Center for Urban African American Aging Research logic model promotes retention through involving older African American adults in research through study referrals and intensive follow-up. The loss of participants due to age- and mobility-related issues indicate the registry may be losing its most vulnerable participants.

Validity of Single-Item Screening for Limited Health Literacy in English and Spanish Speakers

OBJECTIVES

To evaluate 3 single-item screening measures for limited health literacy in a community-based population of English and Spanish speakers.

METHODS

We recruited 324 English and 314 Spanish speakers from a community research registry in Dallas, Texas, enrolled between 2009 and 2012. We used 3 screening measures: (1) How would you rate your ability to read?; (2) How confident are you filling out medical forms by yourself?; and (3) How often do you have someone help you read hospital materials? In analyses stratified by language, we used area under the receiver operating characteristic (AUROC) curves to compare each item with the validated 40-item Short Test of Functional Health Literacy in Adults.

RESULTS

For English speakers, no difference was seen among the items. For Spanish speakers, "ability to read" identified inadequate literacy better than "help reading hospital materials" (AUROC curve = 0.76 vs 0.65; P = .019).

CONCLUSIONS

The "ability to read" item performed the best, supporting use as a screening tool in safety-net systems caring for diverse populations. Future studies should investigate how to implement brief measures in safety-net settings and whether highlighting health literacy level influences providers' communication practices and patient outcomes.

Prevalent Health Concerns Among African American Women Belonging to a National Volunteer Service Organization (The Links, Incorporated)

OBJECTIVE

African American women bear a disproportionate burden of cardiovascular disease (CVD) and cancer. The purpose of this study was to identify prevalent health concerns among African American women who are members of The Links, Incorporated (Links), a large national service organization with health programming for communities of color.

METHODS

Survey data (n = 391) were collected during the 2012 Links National Assembly. Twenty-six health issues were presented within five groups: cancer, CVD, pulmonary disease, chronic conditions, and behavioral health. For each issue, women indicated if it was a concern for "you/your family" or "the African American community" via check-boxes. Differences in the proportions for "you/your family" and "the African American community" were evaluated using the McNemar test.

RESULTS

Hypertension was the most frequently endorsed concern for you/your family (79 %); 73 % indicated this was a concern for the African American community. Sickle cell anemia was the most frequently endorsed concern for the African American community (77 %). Melanoma was the least endorsed health issue overall (15 % you/your family, 55 % community). Breast was the most frequently endorsed cancer concern, while lung was among the least. For 23 out of 26 health issues, the proportion concerned was greater for the "African American community" than for "you/your family" (all p < 0.05).

CONCLUSION

CVD and breast cancer were salient concerns; both are topics for which national awareness campaigns and Links health programming exist. Comparatively lower concern was observed for melanoma, a cancer with known survival disparities, and for lung cancer, a leading cause of death in women.

Multiple Comorbidities and Interest in Research Participation Among Clients of a Nonprofit Food Distribution Site

BACKGROUND

Persons accessing food from nonprofit distribution sites face numerous challenges and typically have significant unmet health needs. However, given limited and intermittent healthcare system engagement, this vulnerable population is underrepresented in clinical research. We sought to better understand the health needs of a nonclinical population to inform future research and interventions.

METHODS

Focus groups were conducted in English (n = 4) and Spanish (n = 4) with clients of Crossroads Community Services (CCS), the largest distributor of North Texas Food Bank. Discussions probed participants' health status, healthcare utilization, understanding and utilization of mammography, and attitudes toward participation in research.

RESULTS

Participants included 42 CCS clients, primarily Hispanic or African American women. Participants reported multiple comorbid conditions among household members, yet utilization of health services was often limited by cost. The majority expressed interest in participating in research to communicate their health concerns and obtain emotional support.

CONCLUSION

CCS clients represent a high-need, under-reached population willing to engage in health-related research that affords them opportunity to connect with peers in group settings and obtain information to improve management of daily life challenges. The Community Assistance Research (CARe) Initiative, a community-academic collaboration, establishes a much-needed opportunity for ongoing clinical research and intervention among this underserved population.

Effectiveness of a community research registry to recruit minority and underserved adults for health research

BACKGROUND

Recruiting minorities and underserved populations into population-based studies is a long standing challenge. This study examined the feasibility of recruiting adults from a community research registry.

METHODS

Ethnically diverse, bilingual staff attended health fairs, inviting adults to join a registry. We examined rates of successful contact, scheduling, and participation for studies that used the registry.

RESULTS

Five studies queried 6,886 research registry members (48% Hispanic and 38% black) and attempted to contact 2,301 potentially eligible participants; eligibility criteria varied across studies. We successfully contacted 1,130 members, 51.9% were scheduled to participate and of those, 60.8% completed their study appointment. Non-Hispanic whites were less likely than Hispanics to be interested, but among those scheduling an appointment, participation did not differ by race/ethnicity.

CONCLUSION

Community research registries are a feasible and efficient method for recruiting minority and underserved adults and may address disparities in access to and participation in health research.

Connecting communities to health research: development of the Project CONNECT minority research registry

INTRODUCTION

Prevention and treatment standards are based on evidence obtained in behavioral and clinical research. However, racial and ethnic minorities remain relatively absent from the science that develops these standards. While investigators have successfully recruited participants for individual studies using tailored recruitment methods, these strategies require considerable time and resources. Research registries, typically developed around a disease or condition, serve as a promising model for a targeted recruitment method to increase minority participation in health research. This study assessed the tailored recruitment methods used to populate a health research registry targeting African-American community members.

METHODS

We describe six recruitment methods applied between September 2004 and October 2008 to recruit members into a health research registry. Recruitment included direct (existing studies, public databases, community outreach) and indirect methods (radio, internet, and email) targeting the general population, local universities, and African American communities. We conducted retrospective analysis of the recruitment by method using descriptive statistics, frequencies, and chi-square statistics.

RESULTS

During the recruitment period, 608 individuals enrolled in the research registry. The majority of enrollees were African American, female, and in good health. Direct and indirect methods were identified as successful strategies for subgroups. Findings suggest significant associations between recruitment methods and age, presence of existing health condition, prior research participation, and motivation to join the registry.

CONCLUSIONS

A health research registry can be a successful tool to increase minority awareness of research opportunities. Multi-pronged recruitment approaches are needed to reach diverse subpopulations.
