Leerschool AR, Wesselius A, Kokole D, Zeegers MP. Changes in acceptability, consideration, intention, and uptake of direct-to-consumer genetic tests in the Netherlands from 2017 to 2022. J Genet Couns 2024. [PMID: 38828901 DOI: 10.1002/jgc4.1919] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 05/01/2024] [Accepted: 05/07/2024] [Indexed: 06/05/2024]
Abstract
Although the popularity of direct-to-consumer genetic tests (DTC-GT) for disease-related purposes increased, concerns persist whether consumers make well-informed decisions about their purchase. To better target pre- and post-test information materials, this study aims to determine the characteristics of people interested in undergoing DTC-GT. In addition, it aims to determine changes in acceptability, consideration, intention, and uptake of DTC-GT since 2017. An online cross-sectional survey was conducted in April 2022 with a representative sample of the Dutch adult population. Ordinal regression models and chi-squared tests were used to determine factors associated with DTC-GT acceptability, consideration and intention, and changes in outcomes since 2017, respectively. Of the 907 included respondents, 19.3% found DTC-GT acceptable, 29.4% considered taking a DTC-GT in the future, 6.2% intended to take a test within the coming year, and 0.9% had already tested. High education was associated with lower acceptability, consideration, intention, and higher awareness. Respondents with a chronic disease were less likely to find DTC-GT acceptable. Higher consideration was associated with having a partner, adopted/stepchildren, and lower age. Compared to 2017, in 2022 more respondents found DTC-GT totally unacceptable, while more considered testing, and fewer ruled out taking a test both in the next year and the future. Education status may play an important role in people's acceptability, consideration, intention, and awareness of disease-related DTC-GT in the Netherlands. Easy-to-understand public information materials should be promoted and guidance is needed to help with decision-making and result interpretation. Future research should focus on the best way to provide responsible guidance.

Cancer patient knowledge about and behavioral intentions after germline genome sequencing. PATIENT EDUCATION AND COUNSELING 2022; 105:707-718.

Abstract
OBJECTIVES Germline genome sequencing (GS) is becoming mainstream in cancer diagnosis and risk management. Identifying knowledge gaps and determinants of health behavior change intentions will enable effective targeting of educational and management strategies to translate genomic findings into improved cancer outcomes. METHODS Probands diagnosed with cancer of likely genetic origin that consented to but not yet undergone GS, and their biological relatives, completed a cross-sectional questionnaire assessing GS knowledge and hypothetical intention to change behaviors. RESULTS Probands (n = 348; 57% university educated) and relatives (n = 213; 38% university educated) had moderate GS knowledge levels, with greater knowledge associated with higher education. Both populations reported high behavioral change intentions, significantly associated with being female (p = 0.01) and greater perceived importance of GS (p < 0.001), and for probands: being from English-speaking households (p = 0.003), higher socio-economic status (p = 0.01) and greater self-efficacy (p = 0.02). CONCLUSIONS Increasing GS knowledge will enable realistic participant expectations surrounding germline GS. Actual behavior change should be monitored to determine whether increased cancer risk knowledge results in altered cancer-related behavior and ultimately, cancer outcomes. PRACTICE IMPLICATIONS Educational resources should target specific populations to ensure informed decision-making and expectation management. Support tools facilitating and maintaining behavioral change may be needed to achieve improved cancer patient outcomes.

"Being proactive, not reactive": exploring perceptions of genetic testing among White, Latinx, and Pacific Islander Populations. J Community Genet 2021; 12:617-630. [PMID: 34415555 DOI: 10.1007/s12687-021-00542-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Accepted: 07/25/2021] [Indexed: 12/20/2022] Open
Abstract
Genetic testing is becoming an integral part of healthcare, but evidence suggests that both race and ethnicity influence access to and utilization of genetic testing. Given this barrier, data are needed on the perceptions of genetic testing in racial and ethnic minority groups. The purpose of this study was to explore the perceptions of three types of genetic testing (genetic testing for adult-onset conditions, prenatal screening, and newborn screening) in a sample of US participants who identified as White, Pacific Islander, and Latinx (10 dyads from each group for 60 participants total). Data were collected through semi-structured dyadic interviews and assessed using thematic analysis. The major themes were knowledge as empowering, knowledge as stressful, and predictive nature of prenatal testing and newborn screening. Some differences were seen in themes by race and ethnicity. A sense of collective and familial health appeared to be a more important theme for Pacific Islander and Latinx participants compared to White participants. Adult-onset genetic testing was viewed variously across all groups with some noting how it may increase anxiety, particularly if the disease screened for was unable to be prevented with action. All three groups reported on the positives of prenatal testing and newborn screening yet often were confused on the differences between them. This study presents novel perceptions of genetic testing in participants from diverse communities across three types of genetic testing. Genetic healthcare providers should incorporate participants' perceptions, values, and beliefs into their counseling delivery as a way to engage with diverse communities.

Behavioral and Psychological Outcomes Associated with Skin Cancer Genetic Testing in Albuquerque Primary Care. Cancers (Basel) 2021; 13:cancers13164053. [PMID: 34439206 PMCID: PMC8394482 DOI: 10.3390/cancers13164053] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Revised: 07/28/2021] [Accepted: 08/03/2021] [Indexed: 11/16/2022] Open
Abstract
Simple Summary Genetic information is publicly available but research examining the best use of such information has not engaged diverse members of the public. We examined public reactions to melanoma genetic testing (using the melanocortin-1 receptor [MC1R] gene) in a study randomizing (like the flip of a coin) 600 diverse primary care patients to a MC1R test offer or usual care. We found that testing did not improve sun protection and skin cancer screening, nor did it lead worry to increase. However, groups less aware of their skin cancer risk, including those who thought their risk was “unlikely” at the start of the study, showed significant improvements in sun protection at three months. In conclusion, testing might be very helpful for certain people who have the most to learn about their risk, who may become motivated to protect themselves from the damaging effects of the sun as a result of skin cancer genetic testing. Abstract Public availability of genetic information is increasing; thus, efforts to improve diversity in basic and translational research in genomics is a top priority. Given the increasing U.S. incidence and mortality of melanoma, and the prevalence of common melanocortin-1 receptor (MC1R) gene melanoma risk variants in the general population, we examined genomic testing of MC1R for skin cancer risk in a randomized controlled trial in Albuquerque, New Mexico primary care. Participants were 48% Hispanic and were randomized 5:1 to a MC1R test invitation or usual care. We assessed 3 month sun protection, skin cancer screening, and skin cancer worry outcomes associated with testing, and key effect moderators (e.g., cancer risk perceptions, and skin cancer risk factors). Our findings indicate that the primary outcomes were unchanged by the MC1R test offer, test acceptance, and level of risk feedback. Moderator analyses showed that those with lower risk perception, and those with skin that readily tans, significantly increased their sun protection in response to higher than average risk feedback. Risk feedback did not prompt cancer worry, and average risk feedback did not erode existing sun protection. This study paves the way for the development of tailored strategies to address low skin cancer risk awareness in this understudied context of public health genomics.

Abstract
Because most research about laypeople and genetic testing (GT) has been conducted in other nations than China, we conducted a study in urban China (a) to determine the perceived knowledge of, attitude toward, and use of GT there; (b) to identify influencing factors associated with the public's perceived knowledge, attitudes, and use of GT; and (c) to explore the relationship among public knowledge of, attitude toward, and use of GT. Our data came from a community-based survey in urban Dalian of 868 individuals. We used generalized ordered logit and logit models to examine factors associated with perceived knowledge of, attitude toward, and use of GT. We found that 67% of community members knew about GT, that 45% had a positive opinion of GT, and that only 4% accessed GT. Older people were more likely to have less perceived knowledge of GT and less likely to have a negative attitude toward it; these relationships were especially stronger among those aged ≥60 years. We also found that socially disadvantaged people were more likely to have less perceived knowledge of GT and more likely to have a negative opinion of it. Having a greater level of perceived knowledge was significantly correlated with increased odds of having a more positive or neutral attitude toward GT and of being more likely to access GT. Our findings may help policy makers design effective action plans and regulations regarding GT and genetic counseling services for laypersons in China.

Abstract
Direct-to-consumer genetic testing (DTCGT) is gaining popularity in Hong Kong (HK). As DTCGT forgoes specialist medical involvement, healthcare professionals have raised concerns regarding its validity, utility, and the public's ability to interpret DTCGT results. Thus, genetic counseling (GC) is recommended to facilitate understanding of DTCGT. This study aimed to investigate HK public's perception toward DTCGT and the importance of GC in DTCGT. A total of 304 HK adults were invited to complete a 37-item survey online. Participants' genomic literacy, understanding and attitude toward DTCGT and GC, and responses to a mock DTCGT scenario were assessed. 48% of participants were aware of DTCGT while 82% indicated an interest. 30% of participants were aware of GC services in HK; 49% were interested in GC services for understanding DTCGT results. Participants scored on average 7.6/11 in the genomic sequencing knowledge scale and were weak in limitations of genomic testing. In the mock DTCGT scenario, 73% of participants expressed concern with the positive results initially. After being explained limitations of DTCGT, 40% of participants reported decreased concern. Reduced perceived helpfulness in medical management and lifestyle modification were also reported by 35% and 27%, respectively. This HK population demonstrated a high level of awareness and interest in DTCGT. As potential DTCGT users, they might experience excess concern and overestimate the usefulness of positive DTCGT results, particularly in medical management. The importance of GC to educate and guide interpretation of DTCGT results is supported; yet the awareness and access of GC services is inadequate in HK.

Abstract
BACKGROUND Direct-to-consumer genetic testing (DTCGT) offers individuals access to information on their probable risks of suffering from a wide range of chronic diseases. General practitioners (GPs) will probably play a major role in supporting its use, but patients' perception of DTCGT remain unclear. This study aimed to describe those attitudes and expectations and how they might affect GPs' daily practices. METHODS In 2018-2019, a study related to the use of DTCGT for preventive care in general medicine was conducted among patients in Switzerland's French-speaking areas. Data were collected in the waiting room using a self-administrated questionnaire about patients' interest in DTCGT and what their attitudes might be if testing revealed an elevated risk of diabetes, colorectal cancer, or Alzheimer's disease. RESULTS About 40% of the 929 participating (participation rate about 80%) patients had heard about DTCGT and, once the test had been explained, 43% reported that they would be interested in being tested. If that testing suggested an elevated risk of disease, the majority of patients reported that they would change their lifestyle (65%-81%, depending on the disease), request more examinations (63%-77%), and expect changes in their GP's follow-up (48%-59%). Personal characteristics such as sex, age, urbanity, marital status, and perceived health were factors predictive of patients' attitudes. CONCLUSION Findings indicated that the generalization of DTCGT might affect GPs' daily practices in terms of workload and knowledge about this approach. However, this result must be qualified by the fact that it is based on hypothetical situations.

Impacts of personal DNA ancestry testing. J Community Genet 2020; 12:37-52.

Abstract
Consumer uptake of direct-to-consumer (DTC) DNA ancestry testing is accelerating, yet few empirical studies have examined test impacts on recipients despite the DTC ancestry industry being two decades old. Participants in a longitudinal cohort study of response to health-related DTC genomic testing also received personal DNA ancestry testing at no additional cost. Baseline survey data from the primary study were analyzed together with responses to an additional follow-up survey focused on the response to ancestry results. Ancestry results were generated for 3466 individuals. Of those, 1317 accessed their results, and 322 individuals completed an ancestry response survey, in other words, approximately one in ten who received ancestry testing responded to the survey. Self-reported race/ethnicity was predictive of those most likely to view their results. While 46% of survey responders (N = 147) reported their ancestry results as surprising or unexpected, less than 1% (N = 3) were distressed by them. Importantly, however, 21% (N = 67) reported that their results reshaped their personal identity. Most (81%; N = 260) planned to share results with family, and 12% (N = 39) intended to share results with a healthcare provider. Many (61%; N = 196) reported test benefits (e.g., health insights), while 12% (N = 38) reported negative aspects (e.g., lack of utility). Over half (N = 162) reported being more likely to have other genetic tests in the future. DNA ancestry testing affected individuals with respect to personal identity, intentions to share genetic information with family and healthcare providers, and the likelihood to engage with other genetic tests in the future. These findings have implications for medical care and research, specifically, provider readiness to engage with genetic ancestry information.

Abstract
Background Genomic risk information, based on common genomic susceptibility variants associated with risk of complex diseases such as cancer, may be incorporated into personalised prevention and screening strategies. We aimed to engage with members of the public, who are important stakeholders in this process, to further inform program development and other implementation outcomes such as acceptability and appropriateness. Methods Semi-structured interviews were undertaken with 30 participants (aged 24–69 years, 50% female) recruited from a pilot trial in which they received personalised genomic risk information for melanoma. We explored participants’ views and attitudes towards offering general personal genomic risk information to the broader population. The data were analysed thematically. Results Two overarching themes relevant to implementation considerations were identified. Firstly, participants’ preferences for accepting an offer of genomic risk information were based on family history, disease incidence and the possibility of prevention. Secondly, participants felt that the processes for offering risk information should be based on individual preferences, triaged according to risk and be supported by a health professional trained in genomics. Conclusions Participants felt that offering personal genomic risk information to the general population to inform prevention and early detection recommendations is acceptable, particularly for common, complex conditions such as cancer. Understanding participants’ preferences for receiving genomic risk information will assist with communication strategies and health workforce planning. We anticipate that these findings will contribute to the development of implementation strategies for incorporating genomic risk information into routine clinical practice.

Abstract
Importance Germline variants in the MC1R gene are common and confer moderate melanoma risk in those with varied skin types. Approaches to precision skin cancer prevention that include genetic information may promote risk awareness and risk reduction in the general population, including Hispanics. Objective To examine prevalence of interest in and uptake of MC1R testing in the general population and examine patterns across demographic and skin cancer risk factors. Design, Setting, and Participants A randomized clinical trial examined interest in and uptake of MC1R testing among patients at University of New Mexico General Internal Medicine clinics. Study participants were randomized to either a usual-care condition (National Cancer Institute skin cancer pamphlet for diverse skin types) or an MC1R test offer. Participants were registered clinic patients (≥6 months) and English or Spanish fluent. Of the 600 participants recruited to the overall trial, the present study included those 499 participants randomized to the MC1R test offer. Interventions Participants were presented with the option to log onto the study website to read 3 educational modules presenting the rationale, benefits, and drawbacks of MC1R testing. Main Outcomes and Measures Main outcomes include website log on (yes vs no), saliva test kit request (yes vs no), and saliva test kit return for MC1R testing (yes vs no). Demographic and skin cancer risk factors were examined as potential predictors of test interest and uptake. Results Of the 499 participants (220 [44%] non-Hispanic white, 242 [48%] Hispanic, 396 [79%] female; mean [SD] age, 54 [14.3] years), 232 (46%) elected to learn about MC1R testing by logging onto the website; 204 (88%) of those who logged on decided to request testing; and 167 (82%) of those who requested testing returned the kit. The strongest predictors of website log on were race/ethnicity and education (non-Hispanic whites were more likely to log on [odds ratio for Hispanics vs non-Hispanic whites, 0.5; 95% CI, 0.3-0.7], as were more highly educated individuals [odds ratio for more than high school vs high school or less, 2.7; 95% CI, 1.7-4.3]). The strongest predictor of ordering the test was sunburn history (odds ratio, 5.4; 95% CI, 2.3-12.9 vs no sunburn history). Conclusions and Relevance There were moderately high levels of MC1R test interest and uptake in this diverse sample. Addressing potential barriers to testing may be warranted as genomic information becomes integrated into general population approaches to the precision prevention of skin cancer. Trial Registration ClinicalTrials.gov identifier: NCT03130569.

Psychosocial and Cultural Determinants of Interest and Uptake of Skin Cancer Genetic Testing in Diverse Primary Care. Public Health Genomics 2019; 22:58-68. [PMID: 31437847 DOI: 10.1159/000501985] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2018] [Accepted: 07/07/2019] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Translational research in genomics has limited reach and requires efforts to broaden access and utility in diverse populations. Skin cancer is common and rates are rising, including among Hispanics. Germline variants in the melanocortin-1 receptor (MC1R) gene are common in the population and confer moderate risk for melanoma and basal cell cancers across skin types. Feedback about MC1R risk status may promote skin cancer risk awareness and risk reduction. AIMS We examined the level of interest in pursuing MC1R testing, and patterns of interest across skin cancer perceived threat and control attitudes, cultural beliefs (family influence on health, health system distrust, cancer fatalism, skin cancer misconceptions), and health literacy. METHODS We used a study website to inform primary care patients in Albuquerque, NM about the benefits and drawbacks of MC1R testing. Website logon, request of a saliva test kit, and return of the test kit (yes vs. no) were primary assessments of study interest and uptake. RESULTS Of 499 participants provided with a test offer, 33% requested and returned the test. Lower family influence on participants' health was an important factor both overall and within ethnicity subgroups, and may indicate that primary care patients interested in skin cancer genetic testing see themselves as proactive health seekers, independent from family encouragement. Lower self-efficacy for skin cancer prevention was also an important characteristic of those who tested. CONCLUSION As evidence for common genetic markers for skin cancer accumulates, these findings suggest characteristics of those most likely to pursue genetic testing for skin cancer risk.

A Scientific Perspective of Personalised Gene-Based Dietary Recommendations for Weight Management. Nutrients 2019; 11:nu11030617. [PMID: 30875721 PMCID: PMC6471589 DOI: 10.3390/nu11030617] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 03/06/2019] [Accepted: 03/09/2019] [Indexed: 01/06/2023] Open
Abstract
Various studies showed that a "one size fits all" dietary recommendation for weight management is questionable. For this reason, the focus increasingly falls on personalised nutrition. Although there is no precise and uniform definition of personalised nutrition, the inclusion of genetic variants for personalised dietary recommendations is more and more favoured, whereas scientific evidence for gene-based dietary recommendations is rather limited. The purpose of this article is to provide a science-based viewpoint on gene-based personalised nutrition and weight management. Most of the studies showed no clinical evidence for gene-based personalised nutrition. The Food4Me study, e.g., investigated four different groups of personalised dietary recommendations based on dietary guidelines, and physiological, clinical, or genetic parameters, and resulted in no difference in weight loss between the levels of personalisation. Furthermore, genetic direct-to-consumer (DTC) tests are widely spread by companies. Scientific organisations clearly point out that, to date, genetic DTC tests are without scientific evidence. To date, gene-based personalised nutrition is not yet applicable for the treatment of obesity. Nevertheless, personalised dietary recommendations on the genetic landscape of a person are an innovative and promising approach for the prevention and treatment of obesity. In the future, human intervention studies are necessary to prove the clinical evidence of gene-based dietary recommendations.

Predispositional genome sequencing in healthy adults: design, participant characteristics, and early outcomes of the PeopleSeq Consortium. Genome Med 2019; 11:10. [PMID: 30808425 PMCID: PMC6391825 DOI: 10.1186/s13073-019-0619-9] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2018] [Accepted: 02/05/2019] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Increasing numbers of healthy individuals are undergoing predispositional personal genome sequencing. Here we describe the design and early outcomes of the PeopleSeq Consortium, a multi-cohort collaboration of predispositional genome sequencing projects, which is examining the medical, behavioral, and economic outcomes of returning genomic sequencing information to healthy individuals. METHODS Apparently healthy adults who participated in four of the sequencing projects in the Consortium were included. Web-based surveys were administered before and after genomic results disclosure, or in some cases only after results disclosure. Surveys inquired about sociodemographic characteristics, motivations and concerns, behavioral and medical responses to sequencing results, and perceived utility. RESULTS Among 1395 eligible individuals, 658 enrolled in the Consortium when contacted and 543 have completed a survey after receiving their genomic results thus far (mean age 53.0 years, 61.4% male, 91.7% white, 95.5% college graduates). Most participants (98.1%) were motivated to undergo sequencing because of curiosity about their genetic make-up. The most commonly reported concerns prior to pursuing sequencing included how well the results would predict future risk (59.2%) and the complexity of genetic variant interpretation (56.8%), while 47.8% of participants were concerned about the privacy of their genetic information. Half of participants reported discussing their genomic results with a healthcare provider during a median of 8.0 months after receiving the results; 13.5% reported making an additional appointment with a healthcare provider specifically because of their results. Few participants (< 10%) reported making changes to their diet, exercise habits, or insurance coverage because of their results. Many participants (39.5%) reported learning something new to improve their health that they did not know before. Reporting regret or harm from the decision to undergo sequencing was rare (< 3.0%). CONCLUSIONS Healthy individuals who underwent predispositional sequencing expressed some concern around privacy prior to pursuing sequencing, but were enthusiastic about their experience and not distressed by their results. While reporting value in their health-related results, few participants reported making medical or lifestyle changes.

Abstract
Precision medicine has grown over the past 20 years with the availability of genetic tests and has changed the one-size-fits-all paradigm in medicine. Precision medicine innovations, such as newly available genetic tests, could potentially widen racial and ethnic disparities if access to them is unequal and if interest to use them differs across groups. The objective of this systematic review was to synthesize existing evidence on racial and ethnic differences in knowledge of and attitudes toward genetic testing among adult patients and the general public in the US, focusing on research about the use of genetic testing in general, not disease-specific tests. Twelve articles published in 1997-2017 met inclusion and exclusion criteria, with 10 including knowledge variables and seven including attitude variables. Studies found consistent patterns of lower awareness of genetic testing in general among non-Whites compared to Whites, lower factual knowledge scores among Blacks and Hispanics/Latinos, and mixed findings of differences in awareness of direct-to-consumer (DTC) genetic testing or the term precision medicine. Blacks, Hispanics/Latinos, and non-Whites generally had more concerns about genetic testing than Whites. The findings suggest that patients and the general public need access to culturally appropriate educational material about the use of genetic testing in precision medicine.

Abstract
Consumer access to third-party services to interpret raw DNA has raised concerns about downstream healthcare implications. This mixed-methods study set out to examine the extent to which genetic counselors have been contacted by consumers of third-party services and describe counselors' experiences with these "consumer" patients. Counselor views on the quality of information provided to consumers were also examined. Eighty-five genetic counselors completed an online survey, of which 22 completed in-depth telephone interviews. Survey and interview data were analyzed and combined using triangulation techniques. Over half (53%) of the survey respondents indicated they had been contacted by a patient following the use of a third-party raw DNA interpretation service. Among counselors contacted, 72% saw at least one patient. Counselors reported challenges unique to this patient population including overemphasis by patients on the validity of the data and patient resistance to information provided by the counselor. Preparation time burden and counselor inexperience and discomfort counseling these patients were additional challenges. Counselors expressed concern about the quality of the raw data and the clarity and usefulness of interpretation reports. Genetic counselors' experiences with consumer's use of third-party DNA interpretation services provide insight on the opportunities and challenges with the availability of raw DNA directly to consumers. Efforts to better support both consumers and genetic service providers are needed to maximize the effective translation of genome-based knowledge for population health.

Abstract
Existing research in consumer behavior suggests that perceptions and usage of a product post-purchase depends, in part, on how the product was marketed, including price paid. In the current study, we examine the effect of providing an out-of-pocket co-payment for consumer genomic testing (CGT) on consumer post-purchase behavior using both correlational field evidence and a hypothetical online experiment. Participants were enrolled in a longitudinal cohort study of the impact of CGT and completed behavioral assessments before and after receipt of CGT results. Most participants provided a co-payment for the test (N = 1668), while others (N = 369) received fully subsidized testing. The two groups were compared regarding changes in health behaviors and post-test use of health care resources. Participants who paid were more likely to share results with their physician (p = .012) and obtain follow-up health screenings (p = .005) relative to those who received fully subsidized testing. A follow-up online experiment in which participants (N = 303) were randomized to a "fully-subsidized" versus "co-payment" condition found that simulating provision of a co-payment significantly increased intentions to seek follow-up screening tests (p = .050) and perceptions of the test results as more trustworthy (p = .02). Provision of an out-of-pocket co-payment for CGT may influence consumer's post-purchase behavior consistent with a price placebo effect. Cognitive dissonance or sunk cost may help explain the increase in screening propensity among paying consumers. Such individuals may obtain follow-up screenings to validate their initial decision to expend personal resources to obtain CGT.

Abstract
In an increasingly data-driven age of medicine, do companies that offer genetic testing directly to patients represent an important part of personalising care, or a dangerous threat to privacy? Should we celebrate this new mechanism of patient involvement, or fear its implications?The Universities of Oxford and Cambridge addressed these issues in the 10th annual Medical Ethics Varsity Debate, through the motion: "This House Regrets the Rise of Direct-to-Consumer Genetic Testing". This article summarises and extends key arguments made in the debate, exploring the impacts of such genetic testing on both the individual patient and broader society, with special consideration as to whether companies can ever truly guarantee anonymity of genetic data.

Abstract
Background The incidence and prevalence of chronic diseases have reached epidemic proportions during the last decades and are not expected to diminish. Chronic diseases increasingly affect younger individuals too, with over 40% of all deaths due to non-communicable diseases occurring before the age of 70. This has led to the development of information services aimed at preventive health care, such as Health Potential®. This counselling service estimates a personal disease risk of a carefully selected list of preventable common chronic diseases that have both a genetic and a lifestyle component of development. The results are delivered face-to-face by a lifestyle counsellor, simultaneously stimulating initial steps towards behaviour change. This information can assist in lifestyle decision-making. Methods/design The primary aim is to study the effect of the Health Potential® service on change in lifestyle behaviour in distinguishable customer populations. The secondary aims are (1) to study the effect of the Health Potential® service on determinants of behaviour change, (2) to study the effect of additional lifestyle counselling on behaviour change and determinants thereof, and (3) to describe the characteristics of the Health Potential® customer. The study consists of two integrated designs: (A) a two-armed non-randomised controlled pre-test/post-test trial (1.5:1 ratio), followed by (B) a two-armed randomised controlled pre-test/post-test trial (1:1 ratio), resulting in three study arms. Participants are clients of local prevention clinics, purchasing a personalised health check (PHC; intervention condition), consisting of Health Potential® and a general health check, or the general health check alone (GHC; control condition) (part A). PHC participants will be randomised to receive four additional lifestyle counselling sessions over a period of 3 months (part B). Discussion This research can provide valuable insights into the effectiveness of and possible ways forward in the field of personalised prevention making use of lifestyle interventions enriched with modern genetic advancements.

Abstract
Objective Next-generation sequencing is increasingly utilized worldwide as a research and diagnostic tool and is anticipated to be implemented into everyday clinical practice. Since Central-Eastern European attitude toward genetic testing, especially broad genetic testing, is not well known, we performed a survey on this issue among Hungarian participants. Methods A self-administered questionnaire was distributed among patients and patient relatives at our neurogenetic outpatient clinic. Members of the general population were also recruited via public media. We used chi-square testing and binary logistic regression to examine factors influencing attitude. Results We identified a mixed attitude toward genetic testing. Access to physician consultation positively influenced attitude. A higher self-determined genetic familiarity score associated with higher perceived genetic influence score, which in turn associated with greater willingness to participate in genetic testing. Medical professionals constituted a skeptical group. Conclusions We think that given the controversies and complexities of the next-generation sequencing field, the optimal clinical translation of NGS data should be performed in institutions which have the unique capability to provide interprofessional health education, transformative biomedical research, and crucial patient care. With optimization of the clinical translational process, improvement of genetic literacy may increase patient engagement and empowerment. Relevance of the article for predictive preventive and personalized medicine The paper highlights that in countries with relatively low-genetic literacy, a special strategy is needed to enhance the implementation of personalized medicine.

Abstract
This study aimed to identify predictors of adverse psychological experiences among direct-to-consumer (DTC) genomic test consumers. We performed a secondary analysis on data from the Scripps Genomic Health Initiative (SGHI), which studied 2037 individuals tested with commercially available tests yielding personalized risk estimates for 23 common, genetically complex diseases. As part of the original study, the participants completed baseline and follow-up survey measures assessing demographics, personal and family health history, attitudes toward genetic testing, anxiety (State-Trait Anxiety Inventory (STAI)), test-related distress (Impact of Event Scale-Revised (IES-R)), and reactions to receipt of results. To further describe the participants who had an adverse psychological outcome, this secondary analysis defined two different variables ("distress response" and "psychologically sensitive participants") and examined their relationship to various demographic variables and other survey responses. One hundred thirty participants (6.4%) were defined as having a "distress response" to receipt of results based on changes in STAI and/or IES. Four hundred thirty-one participants (21.2%) were defined as being "psychologically sensitive" based on high STAI scores both pre- and post-receipt of results. For psychologically sensitive subjects, younger age emerged as a predictor (p < 0.0005). Family history and personal history were only significant predictors for Alzheimer's disease in the psychologically sensitive participants (p = .03) and restless leg syndrome in those with a distress response (p = .03). Psychologically sensitive participants were more likely to indicate a number of pre-test concerns than were controls, but neither group of participants were any more likely to follow up with their physician or a free genetic counseling service after the return of results.

Racial minority group interest in direct-to-consumer genetic testing: findings from the PGen study. J Community Genet 2017; 8:293-301. [PMID: 28868574 DOI: 10.1007/s12687-017-0325-5] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2017] [Accepted: 08/21/2017] [Indexed: 10/18/2022] Open
Abstract
There is little information regarding direct-to-consumer (DTC) personal genetic testing (PGT) in non-White racial minorities. Using a web-based survey, we compared the pretest interests and attitudes toward DTC-PGT of racial minority and White DTC-PGT customers of 23andMe and Pathway Genomics using chi-square tests and multinomial regression. Data were available for 1487 participants (1389 White, 44 Black, and 54 Asian). Survey responses were similar across racial groups, although a greater proportion of Blacks compared to Whites reported being "very interested" in genetic information related to traits (91.9 vs. 70.8%, p = 0.009). A greater proportion of Asians compared to Whites reported that a "very important" consideration for pursuing DTC-PGT was limited information about their family health history (58.0 vs. 37.5%, p = 0.002). While a number of significant differences between groups were observed in unadjusted analyses, they did not remain significant after adjustment. This study provides a preliminary view of the interests for purchasing DTC-PGT among customers with racial minority backgrounds.

Abstract
The development of massively parallel sequencing (or next-generation sequencing) has facilitated a rapid implementation of genomic sequencing in clinical medicine. Genomic sequencing (GS) is now an essential tool for evaluating rare disorders, identifying therapeutic targets in neoplasms, and screening for prenatal aneuploidy. Emerging applications, such as GS for preconception carrier screening and predisposition screening in healthy individuals, are being explored in research settings and utilized by members of the public eager to incorporate genomic information into their health management. The rapid pace of adoption has created challenges for all stakeholders in clinical GS, from standardizing variant interpretation approaches in clinical molecular laboratories to ensuring that nongeneticist clinicians are prepared for new types of clinical information. Clinical GS faces a pivotal moment, as the vast potential of new quantities and types of data enable further clinical innovation and complicated implementation questions continue to be resolved.

Implementing an Internet-Delivered Skin Cancer Genetic Testing Intervention to Improve Sun Protection Behavior in a Diverse Population: Protocol for a Randomized Controlled Trial. JMIR Res Protoc 2017; 6:e52. [PMID: 28442450 PMCID: PMC5424125 DOI: 10.2196/resprot.7158] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2016] [Revised: 02/08/2017] [Accepted: 02/08/2017] [Indexed: 11/13/2022] Open
Abstract
Background Limited translational genomic research currently exists to guide the availability, comprehension, and appropriate use of personalized genomics in diverse general population subgroups. Melanoma skin cancers are preventable, curable, common in the general population, and disproportionately increasing in Hispanics. Objective Variants in the melanocortin-1 receptor (MC1R) gene are present in approximately 50% of the population, are major factors in determining sun sensitivity, and confer a 2-to-3-fold increase in melanoma risk in the general population, even in populations with darker skin. Therefore, feedback regarding MC1R risk status may raise risk awareness and protective behavior in the general population. Methods We are conducting a randomized controlled trial examining Internet presentation of the risks and benefits of personalized genomic testing for MC1R gene variants that are associated with increased melanoma risk. We will enroll a total of 885 participants (462 participants are currently enrolled), who will be randomized 6:1 to personalized genomic testing for melanoma risk versus waiting list control. Control participants will be offered testing after outcome assessments. Participants will be balanced across self-reported Hispanic versus non-Hispanic ethnicity (n=750 in personalized genomic testing for melanoma risk arm; n=135 in control arm), and will be recruited from a general population cohort in Albuquerque, New Mexico, which is subject to year-round sun exposure. Baseline surveys will be completed in-person with study staff and follow-up measures will be completed via telephone. Results Aim 1 of the trial will examine the personal utility of personalized genomic testing for melanoma risk in terms of short-term (3-month) sun protection and skin screening behaviors, family and physician communication, and melanoma threat and control beliefs (ie, putative mediators of behavior change). We will also examine potential unintended consequences of testing among those who receive average-risk personalized genomic testing for melanoma risk findings, and examine predictors of sun protection at 3 months as the outcome. These findings will be used to develop messages for groups that receive average-risk feedback. Aim 2 will compare rates of test consideration in Hispanics versus non-Hispanics, including consideration of testing pros and cons and registration of a decision to either accept or decline testing. Aim 3 will examine personalized genomic testing for melanoma risk feedback comprehension, recall, satisfaction, and cancer-related distress in those who undergo testing, and whether these outcomes differ by ethnicity (Hispanic vs non-Hispanic), or sociocultural or demographic factors. Final outcome data collection is anticipated to be complete by October 2017, at which point data analysis will commence. Conclusions This study has important implications for personalized genomics in the context of melanoma risk, and may be broadly applicable as a model for delivery of personalized genomic feedback for other health conditions.

Abstract
Genomic medicine has revolutionized disease risk identification and subsequent risk reduction interventions. Skin cancer risk genomic feedback is a promising vehicle to raise awareness and protective behaviors in the general population, including Hispanics who are largely unaware of their risks. Yet, personalized genomics currently has limited reach. This study is the initial phase of a randomized controlled trial investigating the personal utility and reach of genomic testing and feedback for melanoma. Semi-structured cognitive interviews (N = 28), stratified across education level, were conducted to assess the comprehension and acceptability of translated skin cancer genomic risk education materials with Spanish-speaking Hispanic primary care patients. Overall, materials were comprehensible and acceptable with 33 of 246 terms/concepts identified as difficult. Common problems included translation challenges (e.g., peeling from sunburn), ambiguous concepts (e.g., healthcare system), and problematic terms (e.g., risk version). Aiming to expand the reach of genomic medicine across subpopulations that may benefit from it, necessary modifications were made to education materials to improve comprehensibility, acceptability, and cultural relevance.

Abstract
OBJECTIVES To explore attitudes of Swiss older adults towards personal genomics (PG). METHODS Using an anonymized voluntary paper-and-pencil survey, data were collected from 151 men and women aged 60-89 years attending the Seniorenuniversität Zurich, Switzerland (Seniors' University). Analyses were conducted using descriptive and inferential statistics. RESULTS One third of the respondents were aware of PG, and more than half indicated interest in undergoing PG testing. The primary motivation provided was respondents' interest in finding out about their own disease risk, followed by willingness to contribute to scientific research. Forty-four percent were not interested in undergoing testing because results might be worrisome, or due to concerns about the validity of the results. Only a minority of respondents mentioned privacy-related concerns. Further, 66% were interested in undergoing clinic-based PG motivated by the opportunity to contribute to scientific research (78%) and 75% of all study participants indicated strong preferences to donate genomic data to public research institutions. CONCLUSION This study indicates a relatively positive overall attitude towards personal genomic testing among older Swiss adults, a group not typically represented in surveys about personal genomics. Genomic data of older adults can be highly relevant to late life health and maintenance of quality of life. In addition they can be an invaluable source for better understanding of longevity, health and disease. Understanding the attitudes of this population towards genomic analyses, although important, remains under-examined.

Abstract
Personal genome sequencing is increasingly utilized by healthy individuals for predispositional screening and other applications. However, little is known about the impact of 'genomic counseling' on informed decision-making in this context. Our primary aim was to compare measures of participants' informed decision-making before and after genomic counseling in the HealthSeq project, a longitudinal cohort study of individuals receiving personal results from whole genome sequencing (WGS). Our secondary aims were to assess the impact of the counseling on WGS knowledge and concerns, and to explore participants' satisfaction with the counseling. Questionnaires were administered to participants (n = 35) before and after their pre-test genomic counseling appointment. Informed decision-making was measured using the Decisional Conflict Scale (DCS) and the Satisfaction with Decision Scale (SDS). DCS scores decreased after genomic counseling (mean: 11.34 before vs. 5.94 after; z = -4.34, p < 0.001, r = 0.52), and SDS scores increased (mean: 27.91 vs. 29.06 respectively; z = 2.91, p = 0.004, r = 0.35). Satisfaction with counseling was high (mean (SD) = 26.91 (2.68), on a scale where 6 = low and 30 = high satisfaction). HealthSeq participants felt that their decision regarding receiving personal results from WGS was more informed after genomic counseling. Further research comparing the impact of different genomic counseling models is needed.

Abstract
One point of consensus in the otherwise very controversial discussion about the benefits and dangers of DTC genetics in the health domain is the lack of substantial clinical utility. At the same time, both the empirical and conceptual literature indicate that health-related DTC tests can have value and utility outside of the clinic. We argue that a broader and multi-faceted conceptualization of utility and value would enrich the ethical and social discussion of DTC testing in several ways: First, looking at ways in which DTC testing can have personal and social value for users – in the form of entertainment, learning, or a way to relate to others – can help to explain why people still take DTC tests, and will, further down the line, foster a more nuanced understanding of secondary and tertiary uses of DTC test results (which could very well unearth new ethical and regulatory challenges). Second, considering the economic value and broader utility of DTC testing foregrounds wider social and political aspects than have been dominant in the ethical and regulatory debates surrounding DTC genetics so far. These wider political aspects include the profound power asymmetries that characterize the collection and use of personal genetic data in many contexts.

Abstract
We propose 'trans-omic' analysis for reconstructing global biochemical networks across multiple omic layers by use of both multi-omic measurements and computational data integration. We introduce technologies for connecting multi-omic data based on prior knowledge of biochemical interactions and characterize a biochemical trans-omic network by concepts of a static and dynamic nature. We introduce case studies of metabolism-centric trans-omic studies to show how to reconstruct a biochemical trans-omic network by connecting multi-omic data and how to analyze it in terms of the static and dynamic nature. We propose a trans-ome-wide association study (trans-OWAS) connecting phenotypes with trans-omic networks that reflect both genetic and environmental factors, which can characterize several complex lifestyle diseases as breakdowns in the trans-omic system.

Abstract
Background Direct-to-consumer genetic tests (DTC-GT) are easily purchased through the Internet, independent of a physician referral or approval for testing, allowing the retrieval of genetic information outside the clinical context. There is a broad debate about the testing validity, their impact on individuals, and what people know and perceive about them. Objective The aim of this review was to collect evidence on DTC-GT from a comprehensive perspective that unravels the complexity of the phenomenon. Methods A systematic search was carried out through PubMed, Web of Knowledge, and Embase, in addition to Google Scholar according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist with the key term “Direct-to-consumer genetic test.” Results In the final sample, 118 articles were identified. Articles were summarized in five categories according to their focus on (1) knowledge of, attitude toward use of, and perception of DTC-GT (n=37), (2) the impact of genetic risk information on users (n=37), (3) the opinion of health professionals (n=20), (4) the content of websites selling DTC-GT (n=16), and (5) the scientific evidence and clinical utility of the tests (n=14). Most of the articles analyzed the attitude, knowledge, and perception of DTC-GT, highlighting an interest in using DTC-GT, along with the need for a health care professional to help interpret the results. The articles investigating the content analysis of the websites selling these tests are in agreement that the information provided by the companies about genetic testing is not completely comprehensive for the consumer. Given that risk information can modify consumers’ health behavior, there are surprisingly few studies carried out on actual consumers and they do not confirm the overall concerns on the possible impact of DTC-GT. Data from studies that investigate the quality of the tests offered confirm that they are not informative, have little predictive power, and do not measure genetic risk appropriately. Conclusions The impact of DTC-GT on consumers’ health perceptions and behaviors is an emerging concern. However, negative effects on consumers or health benefits have yet to be observed. Nevertheless, since the online market of DTC-GT is expected to grow, it is important to remain aware of a possible impact.

Abstract
BACKGROUND Personalized healthcare is expected to yield promising results, with a paradigm shift toward more personalization in the practice of medicine. This emerging field has wide-ranging implications for all the stakeholders. Commercial tests in the form of multiplex genetic profiles are currently being provided to consumers, without the physicians' consultation, through the Internet, referred to as direct-to-consumer genetic tests (DTC GT). OBJECTIVES The objective was to review all the existing European guidelines on DTC GT, and its associated interventions, to list all the supposed benefits and harms, issues and concerns, and recommendations. METHODS We conducted a systematic review of position statements, policies, guidelines, and recommendations, produced by professional organizations or other relevant bodies for use of DTC GT in Europe. RESULTS Seventeen documents met the inclusion criteria, which were subjected to thematic analysis, and the texts were coded for statements related to use of DTC GT. DISCUSSION AND CONCLUSIONS Professional societies and associations are currently more suggestive of potential disadvantages of DTC GT, recommending improved genetic literacy of both populations and health professionals, and implementation research on the genetic tests to integrate public health genomics into healthcare systems.

Abstract
Direct-to-consumer (DTC) advertising of predictive genetic tests (PGTs) has added a new dimension to health advertising. This study used an online survey based on the health belief model framework to examine and more fully understand consumers' responses and behavioral intentions in response to a PGT DTC advertisement. Overall, consumers reported moderate intentions to talk with their doctor and seek more information about PGTs after advertisement exposure, though consumers did not seem ready to take the advertised test or engage in active information search. Those who perceived greater threat from the disease, however, had significantly greater behavioral intentions and information search behavior.

Abstract
BACKGROUND The past 20 years have witnessed successive and exponential advances in genomic discovery and technology, with a broad scientific imperative pushing for continual advancements. The most consistent critique of these advances is that they have vastly outpaced translation of new knowledge into improvements in public health and medicine. METHODS We employ a historical and epistemological analysis to characterize how prevailing scientific meta-narratives have shaped the pace and priorities of research applying genomics to health promotion. We use four 'pivotal events' - the genetic characterization of Down syndrome, the launch of the Human Genome Research Project, the discovery of BRCA1, and the emergence of direct-to- consumer genetic testing - to illustrate how these scientific meta-narratives have inhibited genomic translation research. RESULTS The notion that discovery should precede translation research has over-focused translation research on the latest genetic testing platform. The idea that genetic-related research has an exceptional potential for public harm has encouraged research on worst case scenarios. The perceived competition between genetics and social determinants of health has discouraged a unified research agenda to move genomic translation forward. CONCLUSION We make a case for creating new scientific meta-narratives in which discovery and translation research agendas are envisioned as an interdependent enterprise.

[PMID: 26186621 PMCID: PMC4506048 DOI: 10.1371/journal.pone.0132690] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2014] [Accepted: 06/03/2015] [Indexed: 11/19/2022] Open
Abstract
Genome sequencing is a novel clinical tool that has the potential to identify genetic origins of disease. However, the complexities of this new technology are significant and little is known about its integration into clinical care, and its potential adoption by patients. Expectations of its promise for personalized medicine are high and it is important to properly match expectations to the realities of the test. The NIH ClinSeq cohort study pilots the integration of genome sequencing into clinical research and care to assess the technical, medical and socio-behavioral aspects of implementing this technology. Over 950 adults ages 45-65 have been enrolled and clinically phenotyped. As an initial study, we describe the personality traits of ClinSeq participants, and explore how these traits compare to those that characterize early adopters of other new technologies. Our analysis was conducted on responses from 630 members of the cohort who completed a baseline survey on health cognitions, affect, health-related behaviors and personality traits, prior to receipt of any genome sequencing results. The majority of participants were white (90.5%), had at least a college degree (86.5%), and had at least one biological child (74.6%). Members of this ClinSeq sample were found to be high in dispositional optimism and resilience. Their high SES paralleled that of other early adopters of new technology. These attributes may contribute to participants’ expectations for favorable outcomes and willingness to take higher risks when compared to the general population. These characteristics may distinguish those who are most likely to pursue genome sequencing and be indicative of their psychological resources to manage returned results.

J Med Internet Res 2015; 17:e146.

Abstract
Background In recent years, people who sought direct-to-consumer genetic testing services have been increasingly confronted with an unprecedented amount of personal genomic information, which influences their decisions, emotional state, and well-being. However, these users of direct-to-consumer genetic services, who vary in their education and interests, frequently have little relevant experience or tools for understanding, reasoning about, and interacting with their personal genomic data. Online interactive techniques can play a central role in making personal genomic data useful for these users. Objective We sought to (1) identify the needs of diverse users as they make sense of their personal genomic data, (2) consequently develop effective interactive visualizations of genomic trait data to address these users’ needs, and (3) evaluate the effectiveness of the developed visualizations in facilitating comprehension. Methods The first two user studies, conducted with 63 volunteers in the Personal Genome Project and with 36 personal genomic users who participated in a design workshop, respectively, employed surveys and interviews to identify the needs and expectations of diverse users. Building on the two initial studies, the third study was conducted with 730 Amazon Mechanical Turk users and employed a controlled experimental design to examine the effectiveness of different design interventions on user comprehension. Results The first two studies identified searching, comparing, sharing, and organizing data as fundamental to users’ understanding of personal genomic data. The third study demonstrated that interactive and visual design interventions could improve the understandability of personal genomic reports for consumers. In particular, results showed that a new interactive bubble chart visualization designed for the study resulted in the highest comprehension scores, as well as the highest perceived comprehension scores. These scores were significantly higher than scores received using the industry standard tabular reports currently used for communicating personal genomic information. Conclusions Drawing on multiple research methods and populations, the findings of the studies reported in this paper offer deep understanding of users’ needs and practices, and demonstrate that interactive online design interventions can improve the understandability of personal genomic reports for consumers. We discuss implications for designers and researchers.

Abstract
Whole exome/genome sequencing (WES/WGS) is increasingly offered to ostensibly healthy individuals. Understanding the motivations and concerns of research participants seeking out personal WGS and their preferences regarding return-of-results and data sharing will help optimize protocols for WES/WGS. Baseline interviews including both qualitative and quantitative components were conducted with research participants (n=35) in the HealthSeq project, a longitudinal cohort study of individuals receiving personal WGS results. Data sharing preferences were recorded during informed consent. In the qualitative interview component, the dominant motivations that emerged were obtaining personal disease risk information, satisfying curiosity, contributing to research, self-exploration and interest in ancestry, and the dominant concern was the potential psychological impact of the results. In the quantitative component, 57% endorsed concerns about privacy. Most wanted to receive all personal WGS results (94%) and their raw data (89%); a third (37%) consented to having their data shared to the Database of Genotypes and Phenotypes (dbGaP). Early adopters of personal WGS in the HealthSeq project express a variety of health- and non-health-related motivations. Almost all want all available findings, while also expressing concerns about the psychological impact and privacy of their results.

Abstract
Direct to consumer genetic testing offered via the Internet has been available for over a decade. Initially most tests of this type were offered without the input of the consumer's own health professional. Ethical and practical concerns have been a raised over the use of such tests: these include fulfilling the requirement for informed consent, utility of results for health care management and the potential burden placed upon health services by people who have taken tests.These tests now have an application in reproductive healthcare. The advent of non-invasive prenatal testing has facilitated the genetic testing of the fetus using only a maternal blood sample. However, companies offering such tests, for example for aneuploidy, appear to be doing so based on a referral from the mother's health professional. Preconception or prenatal carrier testing for a range of autosomal recessive conditions can be purchased without the input of a health professional who knows the prospective parents. However, unless the appropriate mutations for the specific population are included in the test, results may create false reassurance. Paternity testing without the consent of the putative father is also available via the Internet, as are tests to ascertain the sex of the fetus, which may be used to select children of a specific gender.Direct-to-consumer tests may support prospective parents to identify genetic risk to their future children, however, it is important that they are aware of the possible limitations, as well as advantages, of these tests. National regulation may not prove effective in ensuring the safety of all individuals involved, therefore international pressure to ensure companies conform to Codes of Practice may be needed, especially in relation to tests that could influence reproductive decisions. However, health professionals have a duty to ensure they are sufficiently knowledgeable to enable them to guide patients appropriately.

Abstract
BACKGROUND As direct-to-consumer personal genome testing (DTC-PGT) is increasingly available in Australia, knowledge of Australians' perceptions and attitudes towards this technology is needed in order to assess the (potential) impact it might have on the Australian public and healthcare system. AIMS To explore the knowledge and perceptions of DTC-PGT in an Australian sample. METHODS An online survey asking about knowledge and perceptions of DTC-PGT, undertaken between October 2011 and April 2012, of 270 Australian residents. Results were analysed using SAS. RESULTS Our study found limited consumer knowledge of, and interest in, pursuing DTC-PGT in Australia. Ninety-three per cent of respondents correctly identified DTC-PGT as available to consumers directly, but only 40% correctly identified its availability in Australia. When asked about the content and value of the information DTC-PGT provides, the majority of respondents indentified that DTC-PGT could provide information about one's health and/or ancestry (82% and 74%). Additionally, respondents indicated they believed this information to be equally important as non-genetic information about one's ancestry and health. CONCLUSION While a minority of respondents expressed an intention to pursue DTC-PGT (27%), the majority of respondents, irrespective of whether they wished to pursue it or not, believed that genetic information was as important as non-genetic information in regards to their health and their ancestry. The value ascribed to genetic information suggests that genetics plays a role in people's lives, and that further qualitative research could explore the ways in which people might use and understand the genetic information provided by DTC-PGT.

Abstract
Home care is on the rise, and its delivery is increasingly reliant on an expanding variety of health technologies ranging from computers to telephone "health apps" to social robots. These technologies are most often predicated on expectations that people in their homes (1) can actively interact with these technologies and (2) are willing to submit to the action of the technology in their home. Our purpose is to use an "ability expectations" lens to bring together, and provide some synthesis of, the types of utility and disadvantages that can arise for people with disabilities in relation to home care technology development and use. We searched the academic databases Scopus, Web of Science, EBSCO ALL, IEEE Xplore, and Compendex to collect articles that had the term "home care technology" in the abstract or as a topic (in the case of Web of Science). We also used our background knowledge and related academic literature pertaining to self-diagnosis, health monitoring, companionship, health information gathering, and care. We examined background articles and articles collected through our home care technology search in terms of ability expectations assumed in the presentation of home care technologies, or discussed in relation to home care technologies. While advances in health care support are made possible through emerging technologies, we urge critical examination of such technologies in terms of implications for the rights and dignity of people with diverse abilities. Specifically, we see potential for technologies to result in new forms of exclusion and powerlessness. Ableism influences choices made by funders, policy makers, and the public in the development and use of home health technologies and impacts how people with disabilities are served and how useful health support technologies will be for them. We urge continued critical examination of technology development and use according to ability expectations, and we recommend increasing incorporation of participatory design processes to counteract potential for health support technology to render people with disabilities technologically excluded and powerless.

Abstract
Individuals who undergo multiplex direct-to-consumer (DTC) genomic testing receive genetic risk results for multiple conditions. To date, research has not investigated the influence of individual differences in disease perceptions among consumers on testing outcomes. A total of 2037 participants received DTC genomic testing and completed baseline and follow-up surveys assessing disease perceptions and health behaviors. Participants were asked to indicate their most feared disease of those tested. Perceived seriousness and controllability of the disease via lifestyle or medical intervention were assessed. Participants most frequently reported heart attack (19.1%) and Alzheimer's disease (18.6%) as their most feared disease. Perceived seriousness and control over the feared disease both influenced response to DTC genomic testing. Greater perceived seriousness and diminished perceived control were associated with higher, but not clinically significant levels of anxiety and distress. In some cases these associations were modified by genetic risk. No significant associations were observed for diet, exercise and screening behaviors. Individual differences in disease perceptions influence psychological outcomes following DTC genomic testing. Higher perceived seriousness may make a consumer more psychologically sensitive to test results and greater perceived control may protect against adverse psychological outcomes. Findings may inform development of educational and counseling services.

Abstract
AIMS This study examined the attitudes of 1,146 Swiss University students to direct-to-consumer (DTC) genomic testing and to genomic research participation. METHODS Data were collected through a self-completion online questionnaire by students from 2 higher education institutions in Zurich, Switzerland. The survey aimed to capture motivation for undergoing or refraining from genomic testing, reactions to mock genetic risk results, and views about contributing data to scientific research. Descriptive and inferential statistics were used for the analysis. RESULTS A total of 1.5% of the students had undergone testing. Most respondents were studying natural sciences and were interested in undergoing DTC genomic testing. The main motive was to contribute their data to scientific research, followed closely by their interest to find out disease risks and personal traits. Overall, 41% of the respondents were not interested in DTC tests. The primary reasons were concerns about receiving potentially worrying results. There was a significant correlation between studying natural sciences, as opposed to the humanities, and interest in undergoing testing. Male respondents were more interested in testing compared to females. There was a strong interest in genetic research participation and notably limited privacy concerns. CONCLUSION Although 59% of the respondents were interested in DTC genomic testing, they were not likely to be affected by them or act upon them. This raises questions about concerns relating to potential risks of DTC genomics users and users' understanding of genetic information including their awareness of privacy risks. Furthermore, the strong interest in genetic research participation signals an underexplored personal utility of genomic testing which needs to be both better understood and better harnessed.

Abstract
BACKGROUND Personalised nutrition (PN) may provide major health benefits to consumers. A potential barrier to the uptake of PN is consumers' reluctance to disclose sensitive information upon which PN is based. This study adopts the privacy calculus to explore how PN service attributes contribute to consumers' privacy risk and personalisation benefit perceptions. METHODS Sixteen focus groups (n = 124) were held in 8 EU countries and discussed 9 PN services that differed in terms of personal information, communication channel, service provider, advice justification, scope, frequency, and customer lock-in. Transcripts were content analysed. RESULTS The personal information that underpinned PN contributed to both privacy risk perception and personalisation benefit perception. Disclosing information face-to-face mitigated the perception of privacy risk and amplified the perception of personalisation benefit. PN provided by a qualified expert and justified by scientific evidence increased participants' value perception. Enhancing convenience, offering regular face-to face support, and employing customer lock-in strategies were perceived as beneficial. CONCLUSION This study suggests that to encourage consumer adoption, PN has to account for face-to-face communication, expert advice providers, support, a lifestyle-change focus, and customised offers. The results provide an initial insight into service attributes that influence consumer adoption of PN.

Abstract
Over recent years, significant debate has centered on whether and how communication of personalized genomic risk information can positively influence health behavior change. Several thoughtful commentaries have cautioned that efforts to incorporate genomic risk feedback to motivate health behavior change have had little success. As a field, we should consider the reasons for this limited success and be strategic in the next steps for this line of research. In this article, we consider several reasons that prior research that integrates personalized genomic information has had relative degrees of success in changing or maintaining health behaviors. We suggest ways forward and outline the possibilities presented by emerging technologies and novel approaches in translational genomic research.

Abstract
Whole exome sequencing (WES) uses next generation sequencing technology to provide information on nearly all functional, protein-coding regions in an individual's genome. Due to the vast amount of information and incidental findings that can be generated from this technology, patient preferences must be investigated to help clinicians consent and return results to patients. Patients (n = 19) who were previously clinically diagnosed with Lynch syndrome, but received uninformative negative Lynch syndrome genetic results through traditional molecular testing methods participated in semi-structured interviews after WES testing but before return of results to explore their views of WES and preferences for return of results. Analyses of interview results found that nearly all participants believed that the benefits of receiving all possible results generated from WES outweighed the undesirable effects. The majority of participants conveyed that relative to coping with a cancer diagnosis, information generated from WES would be manageable. Importantly, participants' experience with Lynch syndrome influenced their notions of genetic determinism, tolerance for uncertain results, and family communication plans. Participants would prefer to receive WES results in person from a genetic counselor or medical geneticist so that an expert could help explain the meaning and implications of the potentially large quantity and range of complicated results. These results underscore the need to study various populations with regard to the clinical use of WES in order to effectively and empathetically communicate the possible implications of this new technology and return results.

BACKGROUND Direct-to-consumer (DTC) genomic testing has generated controversy, however the actual impact of testing on consumer behaviour has been understudied, particularly for pharmacogenomic (PGx) testing. METHODS We recruited a sample of adults who purchased a DTC genomic test and had previously received their genomic test results for complex disease risk. All participants additionally underwent PGx testing. At follow-up, to assess the impact of PGx testing on consumer behaviour, healthcare utilisation and psychological status were compared between approximately a third of participants who had received their PGx results and the remaining two-thirds of participants who were still awaiting results. The PGx test included genetic testing for drug effectiveness or risk of side effects for 12 medications. RESULTS At follow-up, there were 481 PGx test recipients and 844 non-recipients still awaiting results. PGx test recipients had more physician visits (p=0.04) and were more likely to share their results with their physician (p=0.001). Both groups showed a decrease in anxiety symptoms from baseline to follow-up, with a trend for PGx recipients to show less of a decrease compared with non-recipients (p=0.10). PGx recipients were more likely to report that their physician ordered additional tests (p=0.01) based on their genomic test. There were no group differences in follow-up test-related distress (p=0.67). CONCLUSIONS DTC PGx risk profiling among a selected sample of individuals was associated with increased physician utilisation and did not result in any adverse changes in psychological health or follow-up test-related distress.

Attitudes towards Social Networking and Sharing Behaviors among Consumers of Direct-to-Consumer Personal Genomics. J Pers Med 2013; 3:275-87. [PMID: 25562728 PMCID: PMC4251386 DOI: 10.3390/jpm3040275] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2013] [Revised: 08/26/2013] [Accepted: 09/22/2013] [Indexed: 11/17/2022] Open
Abstract
UNLABELLED Little is known about how consumers of direct-to-consumer personal genetic services share personal genetic risk information. In an age of ubiquitous online networking and rapid development of social networking tools, understanding how consumers share personal genetic risk assessments is critical in the development of appropriate and effective policies. This exploratory study investigates how consumers share personal genetic information and attitudes towards social networking behaviors. METHODS Adult participants aged 23 to 72 years old who purchased direct-to-consumer genetic testing from a personal genomics company were administered a web-based survey regarding their sharing activities and social networking behaviors related to their personal genetic test results. RESULTS 80 participants completed the survey; of those, 45% shared results on Facebook and 50.9% reported meeting or reconnecting with more than 10 other individuals through the sharing of their personal genetic information. For help interpreting test results, 70.4% turned to Internet websites and online sources, compared to 22.7% who consulted their healthcare providers. Amongst participants, 51.8% reported that they believe the privacy of their personal genetic information would be breached in the future. CONCLUSION Consumers actively utilize online social networking tools to help them share and interpret their personal genetic information. These findings suggest a need for careful consideration of policy recommendations in light of the current ambiguity of regulation and oversight of consumer initiated sharing activities.
