What is a meaningful result? Disclosing the results of genomic research in autism to research participants.

ABSTRACT: Developments in genomics research have been accompanied by a controversial ethical injunction: that researchers disclose individually relevant research results to research participants. With the explosion of genomic research on complex psychiatric conditions such as autism, researchers must increasingly contend with whether--and which results--to report. We conducted a qualitative study with researchers and participants involved in autism genomics research, including 4 focus groups and 23 interviews with parents of autistic children, and 23 interviews with researchers. Respondents considered genomic research results 'reportable' when results were perceived to explain cause, and answer the question 'why;' that is, respondents set a standard for reporting individually relevant genetic research results to individual participants that is specific to autism, reflecting the metaphysical value that genetic information is seen to offer in this context. In addition to this standard of meaning, respondents required that results be deemed 'true.' Here, respondents referenced standards of validity that were context nonspecific. Yet in practice, what qualified as 'true' depended on evidentiary standards within specific research disciplines as well as fundamental, and contested, theories about how autism is 'genetic.' For research ethics, these finding suggest that uniform and context-free obligations regarding result disclosure cannot readily be specified. For researchers, they suggest that result disclosure to individuals should be justified not only by perceived meaning but also by clarity regarding appropriate evidentiary standards, and attention to the status of epistemological debates regarding the nature and cause of disorders.

Project description:The public health impact of genomic screening can be enhanced by cascade testing. However, cascade testing depends on communication of results to family members. While the barriers and facilitators of family communication have been researched following clinical genetic testing, the factors impacting the dissemination of genomic screening results are unknown. Using the pragmatic Electronic Medical Records and Genomics Network-3 (eMERGE-3) study, we explored the reported sharing practices of participants who underwent genomic screening across the United States. Six eMERGE-3 sites returned genomic screening results for mostly dominant medically actionable disorders and surveyed adult participants regarding communication of results with first-degree relatives. Across the sites, 279 participants completed a 1-month and/or 6-month post-results survey. By 6 months, only 34% of the 156 respondents shared their results with all first-degree relatives and 4% did not share with any. Over a third (39%) first-degree relatives were not notified of the results. Half (53%) of participants who received their results from a genetics provider shared them with all first-degree relatives compared with 11% of participants who received their results from a non-genetics provider. The most frequent reasons for sharing were a feeling of obligation (72%) and that the information could help family members make medical decisions (72%). The most common reasons indicated for not sharing were that the family members were too young (38%), or they were not in contact (25%) or not close to them (25%). These data indicate that the professional returning the results may impact sharing patterns, suggesting that there is a need to continue to educate healthcare providers regarding approaches to facilitate sharing of genetic results within families. Finally, these data suggest that interventions to increase sharing may be universally effective regardless of the origin of the genetic result.

Project description:ImportanceThe goal of preclinical Alzheimer disease (AD) clinical trials is to move diagnosis and treatment to presymptomatic stages, which will require biomarker testing and disclosure.ObjectiveTo assess the short-term psychological outcomes of disclosing amyloid positron emission tomography results to older adults who did not have cognitive impairment.Design, setting, and participantsThis observational study included participants who were screening for a multisite randomized clinical trial that began on February 28, 2014, and is anticipated to be completed in 2022. Participants aged 65 to 85 years who had no known cognitive impairments underwent an amyloid positron emission tomography scan and learned their result from an investigator who used a protocol-specified process that included prescan education and psychological assessments. This report compares participants with elevated amyloid levels with at least 1 available outcome measure with participants who did not have elevated amyloid levels who enrolled in an observational cohort study and received further evaluations. Data were collected from April 2014 to December 2017 and analyzed from March 2019 to October 2019.ExposuresA personal biomarker result described as either an elevated or not elevated amyloid level.Main outcomes and measuresTo assess the immediate and short-term psychological outcome of disclosure, the following validated measures were used: the Geriatric Depression Scale, the state items from the State-Trait Anxiety Inventory, and the Columbia Suicide Severity Rating Scale, as well as the Concerns About AD Scale and the Future Time Perspective Scale to assess changes in participants' perceived risk for AD and perceived remaining life span, respectively.ResultsA total of 1167 participants with elevated amyloid levels and 538 participants with not elevated amyloid levels were included. Participants had a mean (SD) age of 71.5 (4.7) years, 1025 (60.1%) were women, and most were white (1611 [94.5%]) and non-Latino (1638 [96.1%]). Compared with participants who learned that they had a not elevated amyloid result, individuals who learned of an elevated amyloid result were no more likely to experience short-term increases in depression (mean [SD] change in the Geriatric Depression Scale score, 0.02 [1.3] vs 0.04 [1.3]; P = .90), anxiety (mean [SD] change in State-Trait Anxiety Inventory score, -0.02 [3.2] vs -0.15 [3.0]; P = .65), or suicidality (mean [SD] change in the Columbia Suicide Severity Rating Scale score, 0.0 [0.4] vs -0.01 [0.5]; P = .67). Participants with elevated amyloid levels had increased Concern About AD scores (raw change in scores: elevated amyloid group, 0.8 [3.9]; not elevated amyloid group, -0.4 [3.8]; P < .001). Participants with not elevated amyloid levels experienced a slight increase in Future Time Perspective score(mean [SD] score, 1.15 [7.4] points; P < .001); there was no change in time perspective among those receiving an elevated amyloid result (mean [SD] score, 0.33 [7.8] points).Conclusions and relevanceIn this observational preclinical AD study, participants who learned they had elevated amyloid levels did not experience short-term negative psychological sequelae compared with persons who learned they did not have elevated amyloid levels.

Project description:Newer data platforms offer increased opportunity to share multidimensional health data with research participants, but the preferences of participants for which data to receive and how is evolving. Our objective is to describe the preferences and expectations of participants for the return of individual research results within Project Baseline Health Study (PBHS). The PBHS is an ongoing, multicenter, longitudinal cohort study with data from four initial enrollment sites. PBHS participants are recruited from the general population along with groups enriched for heart disease and cancer disease risk. Cross-sectional data on return of results were collected in 2017-2018 from an (1) in-person enrollment survey (n = 1,890), (2) benchmark online survey (n = 1,059), and (3) participant interviews (n = 21). The main outcomes included (1) preferences for type of information to be added next to returned results, (2) participant plans for sharing returned results with a non-study clinician, and (3) choice to opt-out of receiving genetic results. Results were compared by sociodemographic characteristics. Enrollment and benchmark survey respondents were 57.1% and 53.5% female, and 60.0% and 66.2% white, respectively. Participants preferred the following data types be added to returned results in the future: genetics (29.9%), heart imaging, (16.4%), study watch (15.8%), and microbiome (13.3%). Older adults (OR 0.60, 95% CI: 0.41-0.87) were less likely to want their genetic results returned next. Forty percent of participants reported that they would not share all returned results with their non-study clinicians. Black (OR 0.64, 95% CI 0.43-0.95) and Asian (OR 0.47, 95% CI 0.30-0.73) participants were less likely, and older participants more likely (OR 1.45-1.61), to plan to share all results with their clinician than their counterparts. At enrollment, 5.8% of participants opted out of receiving their genetics results. The study showed that substantial heterogeneity existed in participant's preferences and expectations for return of results, and variations were related to sociodemographic characteristics.
