The ethical recruitment of participants with neurological disorders in clinical research requires obtaining initial and ongoing informed consent. The purpose of this study is to characterize barriers faced by research personnel in obtaining informed consent from research participants with neurological disorders and to identify strategies applied by researchers to overcome those barriers. This study was designed as a web-based survey of US researchers with an optional follow-up interview. A subset of participants who completed the survey were selected using a stratified (...) purposeful sampling strategy and invited to participate in an in-depth qualitative interview by phone or video conference. Data were analyzed using a mixed methods approach, including content analysis of survey responses and thematic analysis of interview responses. Over 1 year, 113 survey responses were received from US research personnel directly involved in obtaining informed consent from participants in neurological research. Frequently identified barriers to informed consent included: cognitive and communication impairments (e.g. aphasia), unrealistic expectations of research participants, mistrust of medical research, time constraints, literacy barriers, lack of available social support, and practical or resource-related constraints. Strategies to enhance informed consent included: involving close others to support participant understanding of study-related information, collaborating with more experienced research personnel to facilitate training in obtaining informed consent, encouraging participants to review consent forms in advance of consent discussions, and using printed materials and visual references. Beyond conveying study-related information, researchers included in this study endorsed ethical responsibilities to support deliberation necessary to informed consent in the context of misconceptions about research, unrealistic expectations, limited understanding, mistrust, and/or pressure from close others. Findings highlight the importance of training researchers involved in obtaining informed consent in neurological research to address disease-specific challenges and to support the decision-making processes of potential research participants and their close others.

The ethical principle of ‘respect for persons’ in clinical research has traditionally focused on protecting individuals’ autonomy rights, but respect for participants also includes broader, although less well understood, ethical obligations to regard individuals’ rights, needs, interests and feelings. However, there is little empirical evidence about how to effectively convey respect to potential and current participants. To fill this gap, we conducted exploratory, qualitative interviews with participants in a clinical genomics implementation study. We interviewed 40 participants in English or Spanish (...) about their experiences with respect in the study and perceptions of how researchers in a hypothetical observational study could convey respect or a lack thereof. Most interviewees were female, identified as Hispanic/Latino or non-Hispanic white, reported annual household income under US$60 000 and did not have a Bachelor’s degree ; 30% had limited health literacy. We identified four key domains for demonstrating respect: personal study team interactions, with an emphasis on empathy, appreciation and non-judgment; study communication processes, including following up and sharing results with participants; inclusion, particularly ensuring materials are understandable and procedures are accessible; and consent and authorisation, including providing a neutral informed consent and keeping promises regarding privacy protections. While the experience of respect is inherently subjective, these findings highlight four key domains that may meaningfully demonstrate respect to potential and current research participants. Further empirical and normative work is needed to substantiate these domains and evaluate how best to incorporate them into the practice of research. (shrink)
