Incidental findings of therapeutic misconception in biobank-based research.

ABSTRACT

PURPOSE: This article explores expressions of therapeutic misconception (TM) in a deliberative-engagement project focused on the return of aggregate and individual genetic results from biobank-based research. METHODS: We enrolled 45 self-described African Americans in a deliberative-engagement project to explore their attitudes regarding the return of results from biobank-based research. Four groups of individuals participated in four sessions over 2 days that included both educational and focus-group components. RESULTS: TM was expressed by individuals from both clinics on each day that they met. Three main typological categories of TM were noted (i) the reasons for consenting to participate in a biobank, (ii) the conflation of research with clinical care, and (iii) mistrust about the meaning of biomedical research findings. CONCLUSION: Although trust may explain why some research participants express TM, it was also fueled by mistrust (e.g., a disbelief that a condition described as untreatable was truly untreatable). We also found that TM is not due solely to research participants' misunderstandings but is a bidirectional phenomenon that can be exacerbated by researchers. This finding raises questions about how to engage prospective research participants in the long-term goals of biobank-based research without unintentionally overstating possible short-term clinical benefits.
