Enablers and barriers to engaging under-served groups in research: Survey of the United Kingdom research professional's views.

Abstract

Background: There is a known lack of diversity in research participant populations. This impacts on the generalisability of findings and affects clinician prescribing. In the United Kingdom the research community defines those who are underrepresented as under-served. They are commonly those affected by health inequality and disparity. The notion of under-served is complex, with numerous papers identifying multiple factors that contribute to being under-served and in turn suggesting many strategies to improve engagement.

Methods: Research professionals in the UK were invited to complete an online survey. The broad aim was to explore their views on under-served groups. The findings were analysed using statistical and qualitative methods to identify enablers and barriers to engaging the under-served. Descriptive statistics were utilised with associations compared univariately by chi-square test and logistic regression for multivariable analysis.

Results: A total of 945 completed responses were received. Those identified as under-served in this study reflected the previous body of works with a broader descriptor of ethnic and cultural minorities and the addition of adolescents and young adults. Language and literacy skills had the most impact on being under-served. Only 13% of respondents said they felt equipped to meet the needs of the under-served. The main strategy to increase diversity was community engagement and movement of research delivery into the community. The barriers were funding and time. Training needs identified were linked to community engagement, cultural competence and consent processes.

Conclusions: The UK findings from research professionals reflected the previous literature. Adolescents and young people were added to those identified as under-served. Enablers included community outreach and improvement to communication. Barriers were time, funding, organisational processes and lack of focus. Issues were identified with translation and interpretation services. Training requirements focus on methodologies and methods to engage and the consent processes of those from under-served groups.
