Objective: To assess biobank participants' preferences for disclosure of genetic research results.
Patients and methods: We conducted a cross-sectional survey of participants in the OurGenes, OurHealth, OurCommunity biobank. Respondents were surveyed about preferences for disclosure, importance of disclosure, communication of results with practitioners, and sharing of results after respondents' death. Multivariate regression analysis was used to assess independent sociodemographic and clinical predictors of disclosure preferences. Data collection occurred from June 6, 2011, to June 25, 2012.
Results: Among 1154 biobank participants, 555 (48%) responded. Most thought that research result disclosure was important (90%). Preference for disclosure varied, depending on availability of disease treatment (90% vs 64%, P<.001), high vs low disease risk (79% vs 66%, P<.001), and serious vs mild disease (83% vs 68%, P<.001). More than half of respondents (57%) preferred disclosure even when there is uncertainty about the results' meaning, and 87% preferred disclosure if the disease is highly heritable. Older age was positively associated with interest in disclosure, whereas female sex, nonwhite race, diabetes mellitus, and depression and/or anxiety were negatively associated with disclosure. More than half of respondents (52%) would want their results returned to their nearest biological relative after death.
Conclusions: OurGenes biobank participants report strong preferences for disclosure of research results, and most would designate a relative to receive results after death. Participant preferences for serious vs mild disease, high vs low disease risk, and availability of disease treatment differed significantly. Future research should consider family members' preferences for receiving research results from enrolled research participants.
