Enhancing Biospecimen Knowledge Among Health Care Providers and Representatives From Community Organizations

Community Stakeholders' Perspectives on Introducing Human Papillomavirus Vaccination and Biobanking Evidence-Based Programs Within Medically Underserved Communities: A Community-Engaged Approach

PURPOSE

We explored the perspectives of program coordinators and community leaders from Community-based-organizations (CBOs) and Faith-based-organizations (FBOs) to determine how information on human papillomavirus (HPV) vaccination and biobanking is understood and supported within medically underserved communities, and identified strategies for introducing evidence-based programs (EBP) on HPV vaccination and biobanking within underserved communities.

METHODS

The EPIS framework guided discussions in four focus groups with program coordinators (n = 27) and one-on-one interviews with community leaders (n = 15) from CBOs and FBOs.

RESULTS

Participants reported that community members were aware of HPV vaccination but did not know of the link between HPV infection and cancers. Awareness for biobanking was low. HPV vaccination and biobanking were not priority health concerns among community members due to other health issues. However, HPV vaccination and biobanking were considered sensitive health topics. For HPV vaccination, sensitivity was due to concerns that HPV vaccination promoted sex among adolescents, while for biobanking, sensitivity was due to historical abuses of people of color by the medical community. Participants reported that program coordinators' awareness of HPV vaccination and biobanking depended on their organizations' mission. Neither were considered a priority health concern due to lack of funding. Few EBP were available on HPV vaccination and biobanking. Recommendations on culturally-appropriate strategies for engaging community members on HPV vaccination and biobanking EBP are discussed.

CONCLUSION

Given the promise of HPV vaccination and the Precision Medicine Initiative to reduce cancer disparities, findings elucidate factors to be considered when implementing EBP on HPV vaccination and biobanking into medically underserved communities.

Enrollment and biospecimen collection in a multiethnic family cohort: the Northern California site of the Breast Cancer Family Registry

PURPOSE

Racial/ethnic minorities are often assumed to be less willing to participate in and provide biospecimens for biomedical research. We examined racial/ethnic differences in enrollment of women with breast cancer (probands) and their first-degree relatives in the Northern California site of the Breast Cancer Family Registry from 1996 to 2011.

METHODS

We evaluated participation in several study components, including biospecimen collection, for probands and relatives by race/ethnicity, cancer history, and other factors.

RESULTS

Of 4,780 eligible probands, 76% enrolled in the family registry by completing the family history and risk factor questionnaires and 68% also provided a blood or mouthwash sample. Enrollment was highest (81%) for non-Hispanic whites (NHWs) and intermediate (73-76%) for Hispanics, African Americans, and all Asian American subgroups, except Filipina women (66%). Of 4,279 eligible relatives, 77% enrolled in the family registry, and 65% also provided a biospecimen sample. Enrollment was highest for NHWs (87%) and lowest for Chinese (68%) and Filipinas (67%). Among those enrolled, biospecimen collection rates were similar for NHW, Hispanic, and African American women, both for probands (92-95%) and relatives (82-87%), but lower for some Asian-American subgroups (probands: 72-88%; relatives: 71-88%), foreign-born Asian Americans, and probands those who were more recent immigrants or had low English language proficiency.

CONCLUSIONS

These results show that racial/ethnic minority populations are willing to provide biospecimen samples for research, although some Asian American subgroups in particular may need more directed recruitment methods. To address long-standing and well-documented cancer health disparities, minority populations need equal opportunities to contribute to biomedical research.

Development and validation of the biobanking attitudes and knowledge survey-Spanish (BANKS-SP)

Few research studies with non-English-speaking audiences have been conducted to explore community members' views on biospecimen donation and banking, and no validated Spanish-language multi-scale instruments exist to measure community perspectives on biobanking. This study describes the development and psychometric properties of the Biobanking Attitudes aNd Knowledge Survey-Spanish (BANKS-SP). The BANKS was translated into Spanish using the Brislin method of translation. Draft BANKS-SP items were refined through cognitive interviews, and psychometric properties were assessed in a sample of 85 Spanish-speaking individuals recruited at various community events in a three county area in central west Florida, USA. The final BANKS-SP includes three scales: attitudes, knowledge, and self-efficacy; as well as three single items, which evaluated receptivity and intention to donate a biospecimen for research. The final Cronbach's alpha coefficients for the two scales that use a Likert response format indicated adequate internal consistency (attitudes, α = .79; self-efficacy, α = .91). Intention to donate blood and intention to donate urine were positively correlated with attitudes, self-efficacy, and receptivity to learning more about biobanking (all p's < .001). BANKS-SP-Knowledge was not statistically significantly correlated with other BANKS-SP scales or single items measuring intention to donate a biospecimen for research and receptivity for learning more about biospecimen research. The BANKS-SP attitudes and self-efficacy scales show evidence of satisfactory reliability and validity. Additional research should be conducted with larger samples to assess the BANKS-SP instrument's reliability and validity. A valid and reliable Spanish-language instrument measuring Spanish-speaking community members' views about biobanking may help researchers evaluate relevant communication interventions to enhance understanding, intention, and actual biospecimen donation among this population.
