Abstract
Background: Genetic testing for cardiovascular diseases (CVD) is vital, but is underutilized in Japan due to limited insurance coverage, accessibility, and public disinterest. This study explores demographic factors influencing the decision to undergo CVD genetic testing. Methods and Results: We compared the CVD history and baseline demographics of Japanese adults who underwent genetic testing with those who did not, using an Internet survey. The regression model indicated that men, the young, married individuals, parents, and those with CVD, higher score for rationality, and lower quality of life were more inclined to undergo testing. Conclusions: Targeting strategies for CVD genetic testing could focus on these demographics.

Attitudes towards genetic testing: The role of genetic literacy, motivated cognition, and socio-demographic characteristics. PLoS One 2023; 18:e0293187.

Abstract
Understanding reasons for why people choose to have or not to have a genetic test is essential given the ever-increasing use of genetic technologies in everyday life. The present study explored the multiple drivers of people's attitudes towards genetic testing. Using the International Genetic Literacy and Attitudes Survey (iGLAS), we collected data on: (1) willingness to undergo testing; (2) genetic literacy; (3) motivated cognition; and (4) demographic and cultural characteristics. The 37 variables were explored in the largest to-date sample of 4311 participants from diverse demographic and cultural backgrounds. The results showed that 82% of participants were willing to undergo genetic testing for improved treatment; and over 73%-for research. The 35 predictor variables together explained only a small proportion of variance: 7%-in the willingness to test for Treatment; and 6%-for Research. The strongest predictors of willingness to undergo genetic testing were genetic knowledge and deterministic beliefs. Concerns about data misuse and about finding out unwanted health-related information were weakly negatively associated with willingness to undergo genetic testing. We also found some differences in factors linked to attitudes towards genetic testing across the countries included in this study. Our study demonstrates that decision-making regarding genetic testing is influenced by a large number of potentially interacting factors. Further research into these factors may help consumers to make decisions regarding genetic testing that are right for their specific circumstances.

[PMID: 36935717 PMCID: PMC10017738 DOI: 10.3389/fpubh.2023.920286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 02/02/2023] [Indexed: 03/06/2023] Open
Abstract
Background New health technologies and data offer tailored prevention and spot-on treatments, which can considerably reduce healthcare costs. In healthy individuals, insurers can participate in the creation of health capital through data and preventing the occurrence of a disease. In the onset of a disease, sequencing an individual's genome can provide information leading to the use of more efficient treatments. Both improvements are at the core of the "personalized health" paradigm. As a positive side effect, a reduction in healthcare costs is expected. However, the integration of personalized health in insurance schemes starts with a closer understanding of the demand drivers. Methods Using novel data from a survey carried out in Switzerland, we determine the factors influencing the uptake and sharing of data from genetic tests. In our regression analyses, we use five sets of socioeconomic, lifestyle, health insurance, sentiment, and political beliefs variables. Furthermore, two framings assess the willingness to undertake a test and the readiness to share results with an insurer when the costs of the test are borne by the insurer or the individual. Results We find that socioeconomic, lifestyle, or political belief variables have very little influence on the uptake of tests and the sharing of data. On the contrary, our results indicate that sentiment and insurance factors play a strong role. More precisely, if genetic tests are perceived as a mean to perform health prevention, this pushes individuals to take them. Furthermore, using the insurer's smartphone app leads to an increase of the likelihood to undergo a test and doubles the probability to share related data. Regarding insurance plans and deductible levels, there is no strong correlation neither with the willingness to take a test nor to share the data. Finally, individuals with complementary health insurance plans are less likely to share results. From the framings for the payment of genetic tests, our results indicate a positive effect of the insurer as a payer on the willingness to undertake tests as well as on data sharing. Conclusion Our results lay the ground for a deeper understanding of the role of payers on health decisions and sharing of health-related data. In particular, we find that it is relevant for health insurers to engage with their clients.

Abstract
Undergraduate genetics courses have historically focused on simple genetic models, rather than taking a more multifactorial approach where students explore how traits are influenced by a combination of genes, the environment, and gene-by-environment interactions. While a focus on simple genetic models can provide straightforward examples to promote student learning, they do not match the current scientific understanding and can result in deterministic thinking among students. In addition, undergraduates are often interested in complex human traits that are influenced by the environment, and national curriculum standards include learning objectives that focus on multifactorial concepts. This research aims to discover to what extent multifactorial genetics is currently being assessed in undergraduate genetics courses. To address this, we analyzed over 1,000 assessment questions from a commonly used undergraduate genetics textbook; published concept assessments; and open-source, peer-reviewed curriculum materials. Our findings show that current genetics assessment questions overwhelmingly emphasize the impact of genes on phenotypes and that the effect of the environment is rarely addressed. These results indicate a need for the inclusion of more multifactorial genetics concepts, and we suggest ways to introduce them into undergraduate courses.

Abstract
BACKGROUND Tests to predict the development of chronic diseases in those with a family history of the disease are becoming increasingly available and can identify those who may benefit most from preventive interventions. It is important to understand the acceptability of these predictive approaches to inform the development of tools to support decision making. Whilst data are lacking for many diseases, data are available for ischemic heart disease (IHD). Therefore, this study investigates the willingness of those with a family history of IHD to take a predictive test, and the effect of the test results on risk-related behaviours. METHOD Medline, EMBASE, PsycINFO, LILACS and grey literature were searched. Primary research, including adult participants with a family history of IHD, and assessing a predictive test were included. Qualitative and quantitative outcomes measuring willingness to take a predictive test and the effect of test results on risk-related behaviours were also included. Data concerning study aims, participants, design, predictive test, intervention and findings were extracted. Study quality was assessed using the Standard Quality Assessment Criteria for Evaluating Research Papers from a Variety of Fields and a narrative synthesis undertaken. RESULTS Five quantitative and two qualitative studies were included. These were conducted in the Netherlands (n = 1), Australia (n = 1), USA (n = 1) and the UK (n = 4). Methodological quality ranged from moderate to good. Three studies found that most relatives were willing to take a predictive test, reporting family history (n = 2) and general practitioner (GP) recommendation (n = 1) as determinants of interest. Studies assessing the effect of test results on behavioural intentions (n = 2) found increased intentions to engage in physical activity and smoking cessation, but not healthy eating in those at increased risk of developing IHD. In studies examining actual behaviour change (n = 2) most participants reported engaging in at least one preventive behaviour, particularly medication adherence. CONCLUSION The results suggests that predictive approaches are acceptable to those with a family history of IHD and have a positive impact on health behaviours. Further studies are needed to provide a comprehensive understanding of predictive approaches in IHD and other chronic conditions.

Abstract
OBJECTIVES There is increasing interest in prediction and prevention of RA. It is important to understand the views of those at risk to inform the development of effective approaches. First-degree relatives (FDRs) of RA patients are at increased risk of RA. This study assessed predictors of their interest in predictive testing for RA. METHODS Questionnaires were completed by RA patients (provided with their questionnaire by a healthcare professional) and their FDRs (provided with their questionnaire by their RA proband). FDR surveys assessed interest in taking a predictive test, demographic variables, perceived RA risk, attitudes about predictive testing, autonomy preferences, illness perceptions, avoidance coping and health anxiety. Patient surveys included demographic variables, disease impact, RA duration and treatment. Ordinal logistic regression examined the association between FDRs' characteristics and their interest in predictive testing. Generalized estimating equations assessed associations between patient characteristics and FDRs' interest in predictive testing. RESULTS Three hundred and ninety-six FDRs responded. Paired data from the RA proband were available for 292. The proportion of FDRs interested in predictive testing was 91.3%. Information-seeking preferences, beliefs that predictive testing can increase empowerment over health and positive attitudes about risk knowledge were associated with increased interest. Beliefs that predictive testing could cause psychological harm predicted lower interest. Patient characteristics of the proband were not associated with FDRs' interest. CONCLUSIONS FDRs' interest in predictive testing for RA was high, and factors associated with interest were identified. These findings will inform the development of predictive strategies and informational resources for those at risk.

Abstract
An emerging role for DNA sequencing is to identify people at risk for an inherited cancer syndrome in order to prevent or ameliorate the manifestation of symptoms. Two cancer syndromes, Hereditary Breast and Ovarian Cancer and Lynch Syndrome meet the “Tier 1” evidence threshold established by the Centers for Disease Control and Prevention (CDC) for routine testing of patients with a personal or family history of cancer. Advancements in genomic medicine have accelerated public health pilot programs for these highly medically actionable conditions. In this brief report, we provide descriptive statistics from a survey of 746 US respondents from a Qualtrics panel about the public’s awareness of genetic testing, interest in learning about their cancer risk, and likelihood of participating in a population genetic screening (PGS) test. Approximately of half the respondents were aware of genetic testing for inherited cancer risk (n = 377/745, 50.6%) and would choose to learn about their cancer risk (n-309/635, 48.7%). Characteristics of those interested in learning about their cancer risk differed by educational attainment, age, income, insurance status, having a primary care doctor, being aware of genetic testing, and likelihood of sharing information with family (p < 0.05). A sizeable majority of the respondents who were interested in about learning their cancer risk also said that they were likely to participate in a PGS test that involved a clinical appointment and blood draw, but no out-of-pocket cost (n = 255/309, 82.5%). Reasons for not wanting to participate included not finding test results interesting or important, concerns about costs, and feeling afraid to know the results. Overall, our results suggest that engaging and educating the general population about the benefits of learning about an inherited cancer predisposition may be an important strategy to address recruitment barriers to PGS.

Abstract
Studies suggest that 1-3% of the general population in the United States unknowingly carry a genetic risk factor for a common hereditary disease. Population genetic screening is the process of offering otherwise healthy patients in the general population testing for genomic variants that predispose them to diseases that are clinically actionable, meaning that they can be prevented or mitigated if they are detected early. Population genetic screening may significantly reduce morbidity and mortality from these diseases by informing risk-specific prevention or treatment strategies and facilitating appropriate participation in early detection. To better understand current barriers, facilitators, perceptions, and outcomes related to the implementation of population genetic screening, we conducted a systematic review and searched PubMed, Embase, and Scopus for articles published from date of database inception to May 2020. We included articles that 1) detailed the perspectives of participants in population genetic screening programs and 2) described the barriers, facilitators, perceptions, and outcomes related to population genetic screening programs among patients, healthcare providers, and the public. We excluded articles that 1) focused on direct-to-consumer or risk-based genetic testing and 2) were published before January 2000. Thirty articles met these criteria. Barriers and facilitators to population genetic screening were organized by the Social Ecological Model and further categorized by themes. We found that research in population genetic screening has focused on stakeholder attitudes with all included studies designed to elucidate individuals' perceptions. Additionally, inadequate knowledge and perceived limited clinical utility presented a barrier for healthcare provider uptake. There were very few studies that conducted long-term follow-up and evaluation of population genetic screening. Our findings suggest that these and other factors, such as prescreen counseling and education, may play a role in the adoption and implementation of population genetic screening. Future studies to investigate macro-level determinants, strategies to increase provider buy-in and knowledge, delivery models for prescreen counseling, and long-term outcomes of population genetic screening are needed for the effective design and implementation of such programs.

Abstract
OBJECTIVE To evaluate the association of Jewish cultural and religious identity and denominational affiliation with interest in, intention to undertake and uptake of population-based BRCA (Breast Cancer Gene)-testing. DESIGN Cohort-study set within recruitment to GCaPPS-trial (ISRCTN73338115). SETTING London Ashkenazi-Jewish (AJ) population. POPULATION OR SAMPLE AJ men and women, >18 years. METHODS Participants were self-referred, and attended recruitment clinics (clusters) for pre-test counselling. Subsequently consenting individuals underwent BRCA testing. Participants self-identified to one Jewish denomination: Conservative/Liberal/Reform/Traditional/Orthodox/Unaffiliated. Validated scales measured Jewish Cultural-Identity (JI) and Jewish Religious-identity (JR). Four-item Likert-scales analysed initial 'interest' and 'intention to test' pre-counselling. Item-Response-Theory and graded-response models, modelled responses to JI and JR scales. Ordered/multinomial logistic regression modelling evaluated association of JI-scale, JR-scale and Jewish Denominational affiliation on interest, intention and uptake of BRCA testing. MAIN OUTCOME MEASURES Interest, intention, uptake of BRCA testing. RESULTS In all, 935 AJ women/men of mean age = 53.8 (S.D = 15.02) years, received pre-test education and counselling through 256 recruitment clinic clusters (median cluster size = 3). Denominational affiliations included Conservative/Masorti = 91 (10.2%); Liberal = 82 (9.2%), Reform = 135 (15.1%), Traditional = 212 (23.7%), Orthodox = 239 (26.7%); and Unaffiliated/Non-practising = 135 (15.1%). Overall BRCA testing uptake was 88%. Pre-counselling, 96% expressed interest and 60% intention to test. JI and JR scores were highest for Orthodox, followed by Conservative/Masorti, Traditional, Reform, Liberal and Unaffiliated Jewish denominations. Regression modelling showed no significant association between overall Jewish Cultural or Religious Identity with either interest, intention or uptake of BRCA testing. Interest, intention and uptake of BRCA testing was not significantly associated with denominational affiliation. CONCLUSIONS Jewish religious/cultural identity and denominational affiliation do not appear to influence interest, intention or uptake of population-based BRCA testing. BRCA testing was robust across all Jewish denominations. TWEETABLE ABSTRACT Jewish cultural/religious factors do not affect BRCA testing, with robust uptake seen across all denominational affiliations.

Abstract
Background: Breast cancer is the most common cancer in adult women in Saudi Arabia; however, awareness about molecular testing for breast cancer is insufficient. The authors aimed to assess knowledge and attitudes to determine sociodemographic factors that correlate with perceptions of genetic testing among Saudi women. Materials & methods: This cross-sectional community-based study used a questionnaire to investigate the relationships between various social and economic factors. Results: There was a significant difference in interest in undergoing molecular testing between women in consanguineous and non-consanguineous marriages. Conclusion: The data show that consanguinity adds an extra layer of complexity to other sociodemographic barriers that hinder the efficacy of early breast cancer detection and prevention programs in Saudi Arabia.

[PMID: 33648454 PMCID: PMC7923598 DOI: 10.1186/s12263-021-00683-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 02/06/2021] [Indexed: 01/28/2023]
Abstract
BACKGROUND Despite the increasing number of personalized nutrition services available on the market, nutrigenomics-based level of personalization is still the exception rather than a mainstream activity. This can be partly explained by various factors of consumer acceptance of the new technology. While consumer attitudes toward genetic tests aiming to reveal the risks of a predisposition to various illnesses have already been examined by several research studies worldwide; consumer acceptance of nutrigenomics-based personalized nutrition has only been examined by a significantly lower number of papers, especially in the Central and Eastern European region. OBJECTIVE The purpose of this paper is to examine consumer acceptance of genetic-based personalized nutrition in Hungary. Therefore a national representative survey was conducted involving 1000 individuals. The starting point of the model used is the assumption that the consumer acceptance of personalized nutrition is influenced by its consumer perceptions, which are affected by psychological processes that, in a more general sense, determine acceptance of food innovations. RESULTS The results show that 23.5% of respondents accept genetic test-based personalized nutrition. Women were found to reject the new technology in a significantly smaller proportion than men. The relationship between other demographic variables (i.e. age groups, education and subjective income level) and the perception of genetic-based personalized nutrition is also significant. Our results indicate that it is perceived cost/benefit that is most strongly related to genetically based personalized dietary preferences, followed by perceived risk and subjective norms. Perceived uncertainty and perceived behavioural control, however, have only a weak relationship with genetic-based personalized dietary preferences. CONCLUSIONS Compared with the magnitude of the effect of socio-demographic criteria, it can be concluded that, on the whole, psychological processes in the individual have a greater influence on the development of preferences for genetic-based personalized nutrition than any socio-demographic factor. This also confirms the trend that there are more and more value-added products or value propositions (where a significant part of the value added is to be found in product innovation), for which psychological characteristics are/should be given more emphasis among the segmentation criteria.

Abstract
OBJECTIVE To evaluate factors affecting unselected population-based BRCA testing in Ashkenazi Jews (AJ). DESIGN Cohort-study set within recruitment to the GCaPPS trial (ISRCTN73338115). SETTING North London AJ population. POPULATION OR SAMPLE Ashkenazi Jews women/men >18 years, recruited through self-referral. METHODS Ashkenazi Jews women/men underwent pre-test counselling for BRCA testing through recruitment clinics (clusters). Consenting individuals provided blood samples for BRCA testing. Data were collected on socio-demographic/family history/knowledge/psychological well-being along with benefits/risks/cultural influences (18-item questionnaire measuring 'attitude'). Four-item Likert-scales analysed initial 'interest' and 'intention-to-test' pre-counselling. Uni- and multivariable logistic regression models evaluated factors affecting uptake/interest/intention to undergo BRCA testing. Statistical inference was based on cluster robust standard errors and joint Wald tests for significance. Item-Response Theory and graded-response models modelled responses to 18-item questionnaire. MAIN OUTCOME MEASURES Interest, intention, uptake, attitude towards BRCA testing. RESULTS A total of 935 individuals (women = 67%/men = 33%; mean age = 53.8 (SD = 15.02) years) underwent pre-test genetic-counselling. During the pre-counselling, 96% expressed interest in and 60% indicated a clear intention to undergo BRCA testing. Subsequently, 88% opted for BRCA testing. BRCA-related knowledge (P = 0.013) and degree-level education (P = 0.01) were positively and negatively (respectively) associated with intention-to-test. Being married/cohabiting had four-fold higher odds for BRCA testing uptake (P = 0.009). Perceived benefits were associated with higher pre-counselling odds for interest in and intention to undergo BRCA testing. Reduced uncertainty/reassurance were the most important factors contributing to decision-making. Increased importance/concern towards risks/limitations (confidentiality/insurance/emotional impact/inability to prevent cancer/marriage ability/ethnic focus/stigmatisation) were significantly associated with lower odds of uptake of BRCA testing, and discriminated between acceptors and decliners. Male gender/degree-level education (P = 0.001) had weaker correlations, whereas having children showed stronger (P = 0.005) associations with attitudes towards BRCA testing. CONCLUSIONS BRCA testing in the AJ population has high acceptability. Pre-test counselling increases awareness of disadvantages/limitations of BRCA testing, influencing final cost-benefit perception and decision-making on undergoing testing. TWEETABLE ABSTRACT BRCA testing in Ashkenazi Jews has high acceptability and uptake. Pre-test counselling facilitates informed decision-making.

Abstract
OBJECTIVE To evaluate perceptions toward pharmacogenetic testing of patients undergoing percutaneous coronary intervention (PCI) who are prescribed dual antiplatelet therapy (DAPT) and whether geographical differences in these perceptions exist. PARTICIPANTS AND METHODS TAILOR-PCI is the largest genotype-based cardiovascular clinical trial randomizing participants to conventional DAPT or prospective genotyping-guided DAPT. Enrolled patients completed surveys before and 6 months after randomization. RESULTS A total of 1327 patients completed baseline surveys of whom 28, 29, and 43% were from Korea, Canada and the USA, respectively. Most patients (77%) valued identifying pharmacogenetic variants; however, fewer Koreans (44%) as compared with Canadians (91%) and USA (89%) patients identified pharmacogenetics as being important (P<0.001). After adjusting for age, sex, and country, those who were confident in their ability to understand genetic information were significantly more likely to value identifying pharmacogenetic variants (odds ratio: 30.0; 95% confidence interval: 20.5-43.8). Only 21% of Koreans, as opposed to 86 and 77% of patients in Canada and USA, respectively, were confident in their ability to understand genetic information (P<0.001). CONCLUSION Although genetically mediated clopidogrel resistance is more prevalent amongst Asians, Koreans undergoing PCI identified pharmacogenetic variants as less important to their healthcare, likely related to their lack of confidence in their ability to understand genetic information. To enable successful implementation of pharmacogenetic testing on a global scale, the possibility of international population differences in perceptions should be considered.

Abstract
Objective The aim of this study was to identify the preferences for whole genome sequencing (WGS) tests without genetic counseling. Methods A discrete choice experiment was conducted where participants chose between two hypothetical alternatives consisting of the following attributes: test accuracy, test costs, identified diseases, probability of disease occurrence, and data access. People from the general German population aged ≥18 years were eligible to participate in the survey. We estimated generalized linear mixed effects models, latent class mixed-logit models, and the marginal willingness to pay. Results Three hundred and one participants were included in the final analysis. Overall, the most favored WGS testing attributes were 95% test accuracy, report of severe hereditary diseases and 40% probability of disease development, test costs of €1,000, and access to test results for researchers. Subgroup analysis, however, showed differences in these preferences between males and females. For example, males preferred reporting of results at a 10% probability of disease development and females preferred reporting of results at a 40% probability. The test cost, participant’s educational level, and access to data influenced the willingness to participate in WGS testing in reality. Conclusion The German general population was aware of the importance of genetic research and preferred to provide their own genetic data for researchers. However, among others, the reporting of results with a comparatively relatively low probability of disease development at a level of 40%, and the test accuracy of 95% had a high preference. This shows that the results and consequences of WGS testing without genetic counseling are hard to assess for individuals. Therefore, WGS testing should be supported by qualified genetic counseling, where the attributes and consequences are explained.

Abstract
BACKGROUND Genetic risk assessment for breast cancer and ovarian cancer (BCOC) is expected to make major inroads into mainstream clinical practice. It is important to evaluate the potential impact on women ahead of its implementation in order to maximise health benefits, as predictive genetic testing without adequate support could lead to adverse psychological and behavioural responses to risk disclosure. OBJECTIVE To examine anticipated health behaviour changes and perceived control to disclosure of genetic risk for BCOC and establish demographic and person-specific correlates of adverse anticipated responses in a population-based sample of women. DESIGN Cross-sectional quantitative survey study carried out by the UK Office for National Statistics in January and March 2014. SETTING Face-to-face computer-assisted interviews conducted by trained researchers in participants' homes. PARTICIPANTS 837 women randomly chosen from households across the UK identified from the Royal Mail's Postcode Address File. OUTCOME MEASURES Anticipated health behaviour change and perceived control to disclosure of BCOC risk. RESULTS In response to a genetic test result, most women (72%) indicated 'I would try harder to have a healthy lifestyle', and over half (55%) felt 'it would give me more control over my life'. These associations were independent of demographic factors or perceived risk of BCOC in Bonferroni-corrected multivariate analyses. However, a minority of women (14%) felt 'it isn't worth making lifestyle changes' and that 'I would feel less free to make choices in my life' (16%) in response to BCOC risk disclosure. The former belief was more likely to be held by women who were educated below university degree level (P<0.001) after adjusting for other demographic and person-specific correlates. CONCLUSION These findings indicate that women in the UK largely anticipate that they would engage in positive health behaviour changes in response to BCOC risk disclosure.

Abstract
Genetic testing services for breast cancer are well established in developed countries compared to African populations that bear a disproportionate burden of breast cancer (BC). The objective of this study is to examine the knowledge of professional Nigerian women about BC genetics and their intentions to utilize genetic testing services when it is made available in Nigeria. In this study, 165 lecturers and 189 bankers were recruited and studied using a validated self-administered questionnaire. The respondents' mean age was 34.9 years (SD = 10.9), 6.5% had family history of BC, and 84.7% had limited knowledge of breast cancer genetics. The proportion of women with genetic testing intentions for breast cancer was 87.3%. Health care access (OR = 2.35, 95% CI, 1.07-5.13), religion (OR = 3.51, 95% CI, 1.03-11.92), and perceived personal risk if a close relative had breast cancer (OR = 2.31, 95% CI, 1.05-5.08) independently predicted testing intentions. The genetic testing intentions for BC were high despite limited knowledge about breast cancer genetics. Promotion of BC genetics education as well as efforts to make BC genetic testing services available in Nigeria at reduced cost remains essential.

Abstract
OBJECTIVES It is unclear whether family medical history influences the willingness to undergo genetic testing. This study aimed to determine how family history affected the willingness to undergo genetic testing for salt-sensitive hypertension in patients with and without hypertension. DESIGN Cross-sectional study using a self-administered questionnaire. SETTING Six primary care clinics and hospitals in Japan. PARTICIPANTS Consecutive 1705 outpatients aged >20 years, 578 of whom had hypertension. PRIMARY AND SECONDARY OUTCOME MEASURES The primary outcome variable was the willingness to undergo genetic testing to determine the risk of salt-sensitive hypertension, and the secondary variables were age, sex, education level, family history and concerns about hypertension. Factors associated with a willingness to undergo genetic testing were evaluated in patients with and without hypertension using a logistic regression model. RESULTS In the hypertension and non-hypertension groups, 323 (55.9%) and 509 patients (45.2%), respectively, were willing to undergo genetic testing. This willingness was related with a high level of education (adjusted OR (ad-OR): 1.81, 95% CI 1.12 to 2.93), family history of stroke (1.55, 1.04 to 2.31) and concerns about hypertension (2.04, 1.27 to 3.28) in the hypertension group, whereas in the non-hypertension group, it was influenced by education level (ad-OR: 1.45, 95% CI 1.13 to 1.86), family history of hypertension (1.52, 1.17 to 1.98) and concerns about hypertension (2.03, 1.53 to 2.68). CONCLUSIONS The influence of family history on the willingness to undergo genetic testing for risk of salt-sensitivity hypertension differed between participants with and without hypertension. In particular, participants without hypertension wished to know their likelihood of developing hypertension, whereas those with hypertension were interested to know the risk of stroke (a complication of hypertension). Family history could help better counsel patients about genetic testing on the basis of their medical history.

Abstract
AIM To determine patient knowledge, interest and willingness-to-pay for pharmacogenomics testing in a community pharmacy. PATIENTS & METHODS The link to a cross-sectional, anonymous online survey was distributed to a convenience sample of patients. The contingent valuation method was used to assess willingness-to-pay. RESULTS Twenty seven surveys were completed. Eighty one percent of patients were interested in the service, but patients felt that they would be more likely to use the service if insurance covered the cost. CONCLUSION Patients indicated interest in a pharmacogenomics test, but varying levels of willingness-to-pay. Patients may not be able to connect the benefits of testing to their health, justifying further patient education in order to increase the viability of pharmacogenomics testing as a pharmacy service.

Abstract
The primary aim of this study was to test the feasibility of a public health screening program to identify individuals at high risk of familial hypercholesterolemia through a novel screening approach at a large public venue. A finger-prick, non-fasting lipid panel was obtained, and a survey which consisted of 44 open- and close-ended questions divided into four sections: medical and family history of FH, opinions of cascade genetic testing, patient activation, and demographics was completed. A total of 971 participants met criteria and completed a cholesterol screen. In total, five individuals met either the Simon Broome Register or the Dutch Lipid Clinic Network criteria for possible familial hypercholesterolemia. Participants were generally positive towards genetic testing, and the vast majority listed they had no barriers to communication of genetic testing information to family members. However, the most common barrier listed was lack of communication skills. Our results suggest that a public health screening program for FH is viable at a large public venue. We argue that further research is needed to expand this study to a fully operational screening program.

Abstract
The aim of this study was to improve understanding of smokers’ potential reactions to genetic testing for smoking-related diseases. One thousand twenty-four respondents completed a postal survey; 186were smokers. Questions addressed anticipated psychological and behavioral reactions to genetic test results using hypothetical scenarios. Of smokers, 65% anticipated being motivated to quit smoking upon receiving a positive genetic test result; 39% anticipated being demotivated by a negative result. More smokers anticipated being depressed in response to receiving a positive result for cancer than for heart disease (40% vs. 24%). Anticipated motivation was associated with higher desire to quit and lower nicotine addiction, anticipated depression with poorer understanding of genetic testing, and anticipated demotivation with lower education. Smokers who have a high desire to quit may use genetic testing as a motivational tool. Understanding of genetics may be important in determining how individuals respond to genetic tests for complex diseases.

[PMID: 26612611 PMCID: PMC4698294 DOI: 10.1007/s00439-015-1612-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2015] [Accepted: 11/06/2015] [Indexed: 01/19/2023]
Abstract
To investigate public attitudes towards receiving genetic information arising from a test on a relative, 955 University of Sheffield students and staff were surveyed using disease vignettes. Strength of attitude was measured on whether, in the event of relevant information being discovered, they, as an at-risk relative, would want to be informed, whether the at-risk relative's interest should override proband confidentiality, and, if they had been the proband, willingness to give up confidentiality to inform such relatives. Results indicated considerably more complexity to the decision-making than simple statistical risk. Desire for information only slightly increased with risk of disease manifestation [log odds 0.05 (0.04, 0.06) per percentage point increase in manifestation risk]. Condition preventability was the primary factor increasing desire [modifiable baseline, non-preventable log odds -1.74 (-2.04, -1.44); preventable 0.64 (0.34, 0.95)]. Disease seriousness also increased desire [serious baseline, non-serious log odds -0.89 (-1.19, -0.59); fatal 0.55 (0.25, 0.86)]. Individuals with lower education levels exhibited much greater desire to be informed [GCSE log odds 1.67 (0.64, 2.66)]. Age did not affect desire. Our findings suggest that attitudes were influenced more by disease characteristics than statistical risk. Respondents generally expressed strong attitudes demonstrating that this was not an issue which people felt ambivalent about. We provide estimates of the British population in favour/against disclosure for various disease scenarios.

The psychological impact of undergoing genetic-risk profiling in men with a family history of prostate cancer. Psychooncology 2015; 24:1492-9.

Abstract
BACKGROUND The ability to identify men at genetically high-risk of prostate cancer (PrCa) would enable screening to be targeted at those most in need. This study explored the psychological impact (in terms of general and PrCa-specific worry and risk perceptions) on men with a family history of PrCa, undergoing prostate screening and genetic-risk profiling, within a research study. METHODS A prospective exploratory approach was adopted, incorporating a sequential mixed-method design. Questionnaires were completed at two time points to measure the impact of undergoing screening and genetic-risk profiling. In-depth interviews were completed in a subgroup after all study procedures were completed and analysed using a framework approach. RESULTS Ninety-five men completed both questionnaires, and 26 were interviewed. No measurable psychological distress was detectable in the group as a whole. The interview findings fell into two categories: 'feeling at risk' and 'living with risk'. The feeling of being at risk of PrCa is a part of men's lives, shaped by assumptions and information gathered over many years. Men used this information to communicate about PrCa risk to their peers. Men overestimate their risk of PrCa and have an innate assumption that they will develop PrCa. The interviews revealed that men experienced acute anxiety when waiting for screening results. CONCLUSIONS Personalised genetic-risk assessments do not prevent men from overestimating their risk of PrCa. Screening anxiety is common, and timeframes for receiving results should be kept to a minimum. Methods of risk communication in men at risk of PrCa should be the subject of future research.

Abstract
Background There is a widespread assumption that risk prediction is the major driver of customer interest in personal genomic testing (PGT). However, some customers may also be motivated by finding out whether their existing diseases have a genetic etiology. We evaluated the impact of an existing medical diagnosis on customer interest in condition-specific results from PGT. Methods Using a prospective online survey of PGT customers, we measured customer interest prior to receiving PGT results for 11 health conditions, and examined the association between interest and personal medical history of these conditions using logistic regression. Results We analyzed data from 1,538 PGT customers, mean age 48.7 years, 61 % women, 90 % White, and 47 % college educated. The proportion of customers who were ‘very interested’ in condition-specific PGT varied considerably, from 28 % for ulcerative colitis to 68% for heart disease. After adjusting for demographic and personal characteristics including family history, having a diagnosis of the condition itself was significantly associated with interest in genetic testing for risk of that condition, with odds ratios ranging from 2.07 (95 % CI 1.28-3.37) for diabetes to 19.99 (95 % CI 4.57-87.35) for multiple sclerosis. Conclusions PGT customers are particularly interested in genetic markers for their existing medical conditions, suggesting that the value of genetic testing is not only predictive, but also explanatory.

Abstract
BACKGROUND . While choices about genetic testing are increasingly common for patients and families, and public opinion surveys suggest public interest in genomics, it is not known how adults from the general population value genetic testing for heritable conditions. We sought to understand in a US sample the relative value of the characteristics of genetic tests to identify risk of hereditary colorectal cancer, among the first genomic applications with evidence to support its translation to clinical settings. METHODS . A Web-enabled choice-format conjoint survey was conducted with adults age 50 years and older from a probability-based US panel. Participants were asked to make a series of choices between 2 hypothetical blood tests that differed in risk of false-negative test, privacy, and cost. Random parameters logit models were used to estimate preferences, the dollar value of genetic information, and intent to have genetic testing. RESULTS . A total of 355 individuals completed choice-format questions. Cost and privacy were more highly valued than reducing the chance of a false-negative result. Most (97% [95% confidence interval (CI)], 95%-99%) would have genetic testing to reduce the risk of dying of colorectal cancer in the best scenario (no false negatives, results disclosed to primary care physician). Only 41% (95% CI, 25%-57%) would have genetic testing in the worst case (20% false negatives, results disclosed to insurance company). CONCLUSIONS . Given the characteristics and levels included in the choice, if false-negative test results are unlikely and results are shared with a primary care physician, the majority would have genetic testing. As genomic services become widely available, primary care professionals will need to be increasingly knowledgeable about genetic testing decisions.

Abstract
BACKGROUND For risk-stratified screening to be implemented as a screening program for breast and prostate cancer it has to be accepted among the general population. Investigating public interest in stratified screening and its acceptability to the public is therefore essential since as yet little is known. METHOD Cross-sectional web survey sent to a sample of 10 000 individuals (20-74 years of age) representative of the Swedish population as registered in 2009. RESULTS Among the responders (28%), a vast majority (94%) expressed an interest in knowing their breast or prostate cancer risk and stated wanting to know to 'avoid worrying'. Men and women were equally interested in knowing their prostate and breast cancer risk, respectively. However, men showed more certainty. Trusting the healthcare workers with personal information (63%) as well as genetic information (70%), in order to calculate the risk, did not seem to be a major issue. Furthermore, 87% would agree to get screened more often if identified with a high risk, whereas, if identified with a low risk, only 27% would agree to get screened less often. Finally, although a consultation with a physician seemed to be the preferred way to communicate the risk, a majority would agree to receive it via a letter or a phone call. CONCLUSION Risk-stratified screening has the possibility to be accepted by the general public. Knowledge about interest and acceptability of the prospect of risk-stratified screening for breast and prostate cancer will help when implementing new screening strategies.

Abstract
Genetic testing has a potential in the prevention of genetic diseases, particularly in communities with high rates of consanguineous marriage. Therefore, knowledge, practice, and attitudes of the public in Jordan regarding genetic testing were investigated. Individuals (N = 3,196) were questioned about the concepts of genetic testing and genetic counselors, if they underwent any genetic tests, the type of test, the method of consenting to the test, as well as their level of satisfaction with the privacy of the genetic testing service. The likelihood of pursuing predictive genetic testing for cancer was also investigated. Although almost 70 % of respondents knew the term "genetic testing," only 18 % had undergone genetic testing, primarily the mandatory premarital test. In addition, there was a lack of general knowledge about genetic counselors. Many of those who had genetic testing (45 %) indicated they did not go through a consent process, and a lack of consent was significantly related to dissatisfaction with the privacy of the service. Approximately 55 % of respondents indicated they would potentially pursue predictive genetic testing for cancer. Going for routine health checkups was not significantly correlated with either actual or potential uptake of genetic testing, suggesting health care providers do not play an influential role in patients' testing decisions. Our results show a gap between the knowledge and uptake of genetic testing and may help to guide the design of effective strategies to initiate successful genetic counseling and testing services.

Abstract
BACKGROUND Advancements in genomic testing have led to the identification of single nucleotide polymorphisms (SNPs) associated with prostate cancer. The clinical utility of SNP tests to evaluate prostate cancer risk is unclear. Studies have not examined predictors of interest in novel genomic SNP tests for prostate cancer risk in a diverse population. METHODS Consecutive participants in the Fox Chase Prostate Cancer Risk Assessment Program (PRAP) (n = 40) and unselected men from surgical urology clinics (n = 40) completed a one-time survey. Items examined interest in genomic SNP testing for prostate cancer risk, knowledge, impact of unsolicited findings, and psychosocial factors including health literacy. RESULTS Knowledge of genomic SNP tests was low in both groups, but interest was higher among PRAP men (p < 0.001). The prospect of receiving unsolicited results about ancestral genomic markers increased interest in testing in both groups. Multivariable modeling identified several predictors of higher interest in a genomic SNP test including higher perceived risk (p = 0.025), indicating zero reasons for not wanting testing (vs ≥1 reason) (p = 0.013), and higher health literacy (p = 0.016). CONCLUSIONS Knowledge of genomic SNP testing was low in this sample, but higher among high-risk men. High-risk status may increase interest in novel genomic tests, while low literacy may lessen interest.

Abstract
Personalised nutrition (PN) has the potential to reduce disease risk and optimise health and performance. Although previous research has shown good acceptance of the concept of PN in the UK, preferences regarding the delivery of a PN service (e.g. online v. face-to-face) are not fully understood. It is anticipated that the presence of a free at point of delivery healthcare system, the National Health Service (NHS), in the UK may have an impact on end-user preferences for deliverances. To determine this, supplementary analysis of qualitative data obtained from focus group discussions on PN service delivery, collected as part of the Food4Me project in the UK and Ireland, was undertaken. Irish data provided comparative analysis of a healthcare system that is not provided free of charge at the point of delivery to the entire population. Analyses were conducted using the ‘framework approach’ described by Rabiee (Focus-group interview and data analysis. Proc Nutr Soc 63, 655-660). There was a preference for services to be led by the government and delivered face-to-face, which was perceived to increase trust and transparency, and add value. Both countries associated paying for nutritional advice with increased commitment and motivation to follow guidelines. Contrary to Ireland, however, and despite the perceived benefit of paying, UK discussants still expected PN services to be delivered free of charge by the NHS. Consideration of this unique challenge of free healthcare that is embedded in the NHS culture will be crucial when introducing PN to the UK.

Abstract
Smoking increases the risk of developing lung cancer. Genetic loci have been identified which could form the basis of a lung cancer susceptibility test; but little is known whether such a test would interest or motivate those trying to quit smoking. To address this, we investigated the attitudes of people trying to quit smoking towards genetic susceptibility testing for lung cancer. Participant's attitudes to topics associated with lung cancer susceptibility testing were assessed; were they interested in genetic testing? What impact would a hypothetical high- or low- risk result have on smoking cessation? 680 self-completion questionnaires were given to individuals attending National Health Service stop smoking clinics in three different areas of the United Kingdom between 2011 and 2012. 139 questionnaires were returned, giving a 20 % response rate. Participants expressed an interest in a genetic susceptibility test for lung cancer and almost all reported that a high-risk result would increase their motivation to stop smoking. However, many participants had a neutral attitude towards a low-risk result. Most participants agreed their smoking habit could lead to lung cancer. Lung cancer susceptibility testing may be a useful incentive to help people quit smoking. This study suggests the need for genetic services to work with smoking cessation teams if routine testing becomes available in the future.

Abstract
The notion of educating the public through generic healthy eating messages has pervaded dietary health promotion efforts over the years and continues to do so through various media, despite little evidence for any enduring impact upon eating behaviour. There is growing evidence, however, that tailored interventions such as those that could be delivered online can be effective in bringing about healthy dietary behaviour change. The present paper brings together evidence from qualitative and quantitative studies that have considered the public perspective of genomics, nutrigenomics and personalised nutrition, including those conducted as part of the EU-funded Food4Me project. Such studies have consistently indicated that although the public hold positive views about nutrigenomics and personalised nutrition, they have reservations about the service providers' ability to ensure the secure handling of health data. Technological innovation has driven the concept of personalised nutrition forward and now a further technological leap is required to ensure the privacy of online service delivery systems and to protect data gathered in the process of designing personalised nutrition therapies.

Abstract
BACKGROUND The search to identify genes for the susceptibility to alcohol dependence (AD) is generating interest for genetic risk assessment. The purpose of this study is to examine the level of interest and concerns for genetic testing for susceptibility to AD. METHODS Three hundred four African American adults were recruited through public advertisement. All participants were administered the Genetic Psycho-Social Implication (GPSI) questionnaire, which surveyed their interests in hypothetical genetic testing for AD, as well as their perception of ethical and legal concerns. RESULTS Over 85% of participants were interested in susceptibility genetic testing; however, persons with higher education (p=0.002) and income (p=0.008) were less willing to receive testing. Perception of AD as a deadly disease (48.60%) and wanting to know for their children (47.90%) were the strongest reasons for interest in testing. Among those not interested in testing, the belief that they were currently acting to lower their risk was the most prevalent. The most widely expressed concern in the entire sample was the accuracy of testing (35.50%). Other notable concerns, such as issues with the method of testing, side effects of venipuncture, falsely reassuring results, and lack of guidelines on "what to do next" following test results, were significantly associated with willingness to receive testing. CONCLUSION Although an overwhelming majority of participants expressed an interest in genetic testing for AD, there is an understandable high level of methodological and ethical concerns. Such information should form the basis of policies to guide future genetic testing of AD.

Abstract
It is not yet known whether healthy individuals and patients with a chronic disease have similar attitudes towards pharmacogenomics. Thus we conducted a survey of 175 healthy volunteers, 175 heart failure (HF) patients and 100 heart transplant recipients to compare their opinions on this subject. Most participants (>90%) stated that they would accept pharmacogenomic testing and expressed high hopes regarding its potential applications. Overall, interest for pharmacogenomics was shared equally among the three groups. In contrast, after adjusting for age, gender, education and income, healthy individuals were more likely to voice concerns about potential employment (P=0.008 vs HF, odds ratio (OR)=2.93, confidence interval (CI)=1.33-6.47; P=0.010 vs Transplant, OR=2.46, CI=1.24-4.90) and insurance discrimination (P=0.001 vs HF, OR=5.58, CI=2.01-15.48; P<0.001 vs Transplant, OR=4.98, CI=2.03-12.21) and were possibly more worried by confidentiality issues. These findings highlight the need for strict legislation and proper educational strategies directed at the general population to facilitate the clinical implementation of pharmacogenomics.

Abstract
BACKGROUND While primary care systematically offers conventional cardiovascular risk assessment, genetic tests for coronary heart disease (CHD) are increasingly commercially available to patients. It is unclear how individuals may respond to these new sources of risk information. AIM To explore how patients who have had a recent conventional cardiovascular risk assessment, perceive additional information from genetic testing for CHD. DESIGN AND SETTING Qualitative interview study in 12 practices in Nottinghamshire from both urban and rural settings. METHOD Interviews were conducted with 29 adults, who consented to genetic testing after having had a conventional cardiovascular risk assessment. RESULTS Individuals' principal motivation for genetic testing was their family history of CHD and a desire to convey the results to their children. After testing, however, there was limited recall of genetic test results and scepticism about the value of informing their children. Participants dealt with conflicting findings from the genetic test, family history, and conventional assessment by either focusing on genetic risk or environmental lifestyle factors. In some participants, genetic test results appeared to reinforce healthy behaviour but others were falsely reassured, despite having an 'above-average' conventional cardiovascular risk score. CONCLUSION Although genetic testing was acceptable, participants were unclear how to interpret genetic risk results. To facilitate healthy behaviour, health professionals should explore patients' understanding of genetic test results in light of their family history and conventional risk assessment.

Abstract
Background: Type 2 diabetes (T2D) and coronary heart disease (CHD) are prevalent chronic diseases from which military personnel are not exempt. While many genetic markers for these diseases have been identified, the clinical utility of genetic risk testing for multifactorial diseases such as these has not been established. The need for a behavioral intervention such as health coaching following a risk counseling intervention for T2D or CHD also has not been explored. Here we present the rationale, design, and protocol for evaluating the clinical utility of genetic risk testing and health coaching for active duty US Air Force (AF) retirees and beneficiaries. Primary Study Objectives: Determine the direct and interactive effects of health coaching and providing genetic risk information when added to standard risk counseling for CHD and T2D on health behaviors and clinical risk markers. Design: Four-group (2 X 2 factorial) randomized controlled trial. Setting: Two AF primary care clinical settings on the west coast of the United States. Participants: Adult AF primary care patients. Intervention: All participants will have a risk counseling visit with a clinic provider to discuss personal risk factors for T2D and CHD. Half of the participants (two groups) will also learn of their genetic risk testing results for T2D and CHD in this risk counseling session. Participants randomized to the two groups receiving health coaching will then receive telephonic health coaching over 6 months. Main Outcome Measures: Behavioral measures (self-reported dietary intake, physical activity, smoking cessation, medication adherence); clinical outcomes (AF composite fitness scores, weight, waist circumference, blood pressure, fasting glucose, lipids, T2D/CHD risk scores) and psychosocial measures (self-efficacy, worry, perceived risk) will be collected at baseline and 6 weeks, and 3, 6, and 12 months. Conclusion: This study tests novel strategies deployed within existing AF primary care to increase adherence to evidence-based diet, physical activity, smoking cessation, and medication recommendations for CHD and T2D risk reduction through methods of patient engagement and self-management support.

Informed decision-making among students analyzing their personal genomes on a whole genome sequencing course: a longitudinal cohort study. Genome Med 2013; 5:113.

Abstract
Background Multiple laboratories now offer clinical whole genome sequencing (WGS). We anticipate WGS becoming routinely used in research and clinical practice. Many institutions are exploring how best to educate geneticists and other professionals about WGS. Providing students in WGS courses with the option to analyze their own genome sequence is one strategy that might enhance students’ engagement and motivation to learn about personal genomics. However, if this option is presented to students, it is vital they make informed decisions, do not feel pressured into analyzing their own genomes by their course directors or peers, and feel free to analyze a third-party genome if they prefer. We therefore developed a 26-hour introductory genomics course in part to help students make informed decisions about whether to receive personal WGS data in a subsequent advanced genomics course. In the advanced course, they had the option to receive their own personal genome data, or an anonymous genome, at no financial cost to them. Our primary aims were to examine whether students made informed decisions regarding analyzing their personal genomes, and whether there was evidence that the introductory course enabled the students to make a more informed decision. Methods This was a longitudinal cohort study in which students (N = 19) completed questionnaires assessing their intentions, informed decision-making, attitudes and knowledge before (T1) and after (T2) the introductory course, and before the advanced course (T3). Informed decision-making was assessed using the Decisional Conflict Scale. Results At the start of the introductory course (T1), most (17/19) students intended to receive their personal WGS data in the subsequent course, but many expressed conflict around this decision. Decisional conflict decreased after the introductory course (T2) indicating there was an increase in informed decision-making, and did not change before the advanced course (T3). This suggests that it was the introductory course content rather than simply time passing that had the effect. In the advanced course, all (19/19) students opted to receive their personal WGS data. No changes in technical knowledge of genomics were observed. Overall attitudes towards WGS were broadly positive. Conclusions Providing students with intensive introductory education about WGS may help them make informed decisions about whether or not to work with their personal WGS data in an educational setting.

Abstract
BACKGROUND Genetic testing and family history assessment can be used as an aid in the prevention of common chronic diseases. The aim of this study was to determine public attitudes and interests towards offering genetic testing and family history-based risk assessment for common chronic disease prevention. METHODS Cross-sectional questionnaire survey of a consumer panel representative for the Dutch population. The questionnaire was sent to 1399 panel members, aged ≥ 18 years. RESULTS The response was 70% (978/1399). About half of the respondents expressed an interest in genetic testing to prevent specific diseases (cancer, cardiovascular disease, diabetes or dementia), with lower-educated respondents showing more interest than higher-educated respondents. Few respondents (24%) agreed that people should be preventively tested for all kinds of diseases. According to the respondents, genetic testing should be performed in the hospital (66%) and be directed to curable (57%) or preventable diseases (69%). Half of the respondents believed that family history assessment could help prevent disease, but only 21% thought it should be offered to everyone, as this could cause people to be worried. A minority (12%) reported that their family history had been assessed, whereas 59% did not have it assessed and did not think this would be necessary. Respondents have differentiated interests in preventive genomics, which varies depending on sex, age and level of education. CONCLUSIONS Members of the public are interested in genetic testing for preventable and curable diseases, but they are ambivalent about family history risk assessment to prevent disease.

Willingness to participate in genomics research and desire for personal results among underrepresented minority patients: a structured interview study. J Community Genet 2013; 4:469-82.

Abstract
Patients from traditionally underrepresented communities need to be involved in discussions around genomics research including attitudes towards participation and receiving personal results. Structured interviews, including open-ended and closed-ended questions, were conducted with 205 patients in an inner-city hospital outpatient clinic: 48 % of participants self-identified as Black or African American, 29 % Hispanic, 10 % White; 49 % had an annual household income of <$20,000. When the potential for personal results to be returned was not mentioned, 82 % of participants were willing to participate in genomics research. Reasons for willingness fell into four themes: altruism; benefit to family members; personal health benefit; personal curiosity and improving understanding. Reasons for being unwilling fell into five themes: negative perception of research; not personally relevant; negative feelings about procedures (e.g., blood draws); practical barriers; and fear of results. Participants were more likely to report that they would participate in genomics research if personal results were offered than if they were not offered (89 vs. 62 % respectively, p < 0.001). Participants were more interested in receiving personal genomic risk results for cancer, heart disease and type 2 diabetes than obesity (89, 89, 91, 80 % respectively, all p < 0.001). The only characteristic consistently associated with interest in receiving personal results was disease-specific worry. There was considerable willingness to participate in and desire for personal results from genomics research in this sample of predominantly low-income, Hispanic and African American patients. When returning results is not practical, or even when it is, alternatively or additionally providing generic information about genomics and health may also be a valuable commodity to underrepresented minority and other populations considering participating in genomics research.

Abstract
It is predicted that non-communicable diseases will account for over 73 % of global mortality in 2020. Given that the majority of these deaths occur in developed countries such as the UK, and that up to 80 % of chronic disease could be prevented through improvements in diet and lifestyle, it is imperative that dietary guidelines and disease prevention strategies are reviewed in order to improve their efficacy. Since the completion of the human genome project our understanding of complex interactions between environmental factors such as diet and genes has progressed considerably, as has the potential to individualise diets using dietary, phenotypic and genotypic data. Thus, there is an ambition for dietary interventions to move away from population-based guidance towards 'personalised nutrition'. The present paper reviews current evidence for the public acceptance of genetic testing and personalised nutrition in disease prevention. Health and clear consumer benefits have been identified as key motivators in the uptake of genetic testing, with individuals reporting personal experience of disease, such as those with specific symptoms, being more willing to undergo genetic testing for the purpose of personalised nutrition. This greater perceived susceptibility to disease may also improve motivation to change behaviour which is a key barrier in the success of any nutrition intervention. Several consumer concerns have been identified in the literature which should be addressed before the introduction of a nutrigenomic-based personalised nutrition service. Future research should focus on the efficacy and implementation of nutrigenomic-based personalised nutrition.

Abstract
Genetic testing for chronic disease susceptibility may motivate young adults for preventive behavior change. This nationally representative survey gave 521 young adults hypothetical scenarios of receiving genetic susceptibility results for heart disease, type 2 diabetes, and stroke and asked their (1) interest in such testing, (2) anticipated likelihood of improving diet and physical activity with high- and low-risk test results, and (3) readiness to make behavior change. Responses were analyzed by presence of established disease-risk factors. Respondents with high phenotypic diabetes risk reported increased likelihood of improving their diet and physical activity in response to high-risk results compared with those with low diabetes risk (odds ratio (OR), 1.82 (1.03, 3.21) for diet and OR, 2.64 (1.24, 5.64) for physical activity). In contrast, poor baseline diet (OR, 0.51 (0.27, 0.99)) and poor physical activity (OR, 0.53 (0.29, 0.99)) were associated with decreased likelihood of improving diet. Knowledge of genetic susceptibility may motivate young adults with higher personal diabetes risk for improvement in diet and exercise, but poor baseline behaviors are associated with decreased intention to make these changes. To be effective, genetic risk testing in young adults may need to be coupled with other strategies to enable behavior change.

Abstract
Ten years after the Human Genome Project, medicine is still waiting for many of the promised benefits, and experts have tempered their high expectations. Public opinion on genetic testing has generally been favourable but is this still the case? The aim of this study is to compare public experiences, beliefs and expectations concerning genetic testing over the years (2002 vs 2010). A cross-sectional questionnaire survey was conducted using the Dutch Health Care Consumer Panel in 2002 and 2010. Responses to questions in identical wording were compared. In 2002 and 2010, 817 (63%) and 978 (70%) members responded, respectively. Awareness and reported use of genetic tests remained stable over time. In 2010, more respondents expected genetic testing to become more widely applied, believed that knowledge about the genetic background of disease helps people live longer, and that testing should be promoted more intensively. In 2010, they were also more interested in their own genetic make-up. On the one hand, the concern that a dichotomy would emerge between people with 'good genes' and 'bad genes' was higher. On the other hand, respondents thought that insurance companies would be less likely to demand a genetic test in order to calculate health insurance premiums. In conclusion, the results suggest that in 8 years, expectations of benefits and potential use of genetic testing have been raised among the public, resulting in more positive opinions. Worries on inequity remain, although worries about premium differentiation by insurance companies have decreased.

Abstract
We compared three common user involvement methods in revealing barriers and facilitators from intended users that might influence their use of a new genetic test. The study was part of the development of a new genetic test on the susceptibility to hand eczema for nurses. Eighty student nurses participated in five focus groups (n = 33), 15 interviews (n = 15) or questionnaires (n = 32). For each method, data were collected until saturation. We compared the mean number of items and relevant remarks that could influence the use of the genetic test obtained per method, divided by the number of participants in that method. Thematic content analysis was performed using MAXQDA software. The focus groups revealed 30 unique items compared to 29 in the interviews and 21 in the questionnaires. The interviews produced more items and relevant remarks per participant (1.9 and 8.4 pp) than focus groups (0.9 and 4.8 pp) or questionnaires (0.7 and 2.3 pp). All three involvement methods revealed relevant barriers and facilitators to use a new genetic test. Focus groups and interviews revealed substantially more items than questionnaires. Furthermore, this study suggests a preference for the use of interviews because the number of items per participant was higher than for focus groups and questionnaires. This conclusion may be valid for other genetic tests as well.

Abstract
PURPOSE Dramatic advances in genomic technology stand to revolutionize cancer care; however, little is known about patients' understanding and acceptance of personalized medicine and widespread genetic testing (GT). PATIENTS AND METHODS We conducted a formative, semi-structured interview study with a random sample of patients with lung, colorectal, and breast cancers to assess awareness of personalized medicine and GT and attitudes about somatic GT. Willingness to undergo GT was elicited through hypothetic scenarios. RESULTS Sixty-nine patients participated; 71% were women; 42% were black; median age was 59 years; and 42% had an education level ≥ college. We found that a majority of patients either were not aware of the term "personalized medicine" or defined it in unexpected ways. Although many patients identified relevant benefits of somatic testing (eg, informs treatment), many patients also expressed significant concerns (ie, psychological harm and discrimination). A majority of patients expressed a willingness to undergo somatic (predictive, 96%, prognostic, 93%) and germline (cancer risk without incidental information, 87%; cancer risk with incidental information, 81%; pharmacogenetic, 91%) testing; however, far fewer patients expressed a willingness to undergo full genome sequencing (62%). Reluctance was attributed to concerns over incidental findings, information overload, and the lack of a clear benefit. CONCLUSION Many patients relayed misunderstandings about somatic testing and a reluctance to undergo full sequencing; oncologists must carefully consider how they present testing to patients so that concerns over discrimination and psychological harm do not hinder test uptake. More work is needed to identify effective ways to communicate complex genomic concepts to patients and research participants.

Abstract
Genetic testing for obesity risk is increasingly available to the public but few studies have examined motivational or affective reactions. Here we report findings from a "vignette" study investigating reactions to "higher-risk" and "average-risk" results for the obesity-related FTO gene in two groups: a panel sample of individuals with weight concerns, for whom testing may have treatment implications (n = 306, mean age = 45 years, mean BMI = 35) and a student sample (n = 395, mean age = 25 years, mean BMI = 23), for whom testing would have implications for obesity prevention. Participants were given FTO gene information that described higher-risk alleles as linked with modest weight gain and slightly higher risk of obesity. They responded to both higher- and average-risk vignettes, with order randomized. Interest in genetic testing was high overall, and higher in panel respondents than students (93% vs. 78% would "probably" or "definitely" have the test; P < 0.001). In students, a higher-risk result generated higher motivation to change (d = 0.15; P < 0.001), but also slightly higher negative affect (d = 0.03, P < 0.001) and fatalism (d = 0.05, P < 0.001) than an average-risk result. Panel respondents also had higher motivation to change (d = 0.17, P < 0.001) as well as relief about having an explanation for their body weight (d = 0.02, P = 0.013) in the higher-risk condition, but no increase in fatalism or depression. These results suggest that at the level of anticipated responses to FTO gene feedback, higher-risk results had positive motivational effects with minimal changes in negative affect or fatalism. Genetic testing has the potential to be a useful clinical or preventive tool when combined with appropriate information.

Abstract
The aim of this study was to establish key characteristics that patients, consumers, and health professionals value regarding genetic testing (GT) and personalized medicine using the example of GT for hereditary Lynch syndrome. We conducted a series of focus groups with individuals recruited from a clinic that follows those at high risk for hereditary cancer, individuals recruited from the community, physicians, and genetic counselors. Participants were presented with clinical scenarios about Lynch syndrome testing and asked to identify characteristics that they perceived as important in making decisions about GT. Forty-two participants (19 community members, 8 high-risk and cancer patients, 3 genetic counselors, and 8 physicians) participated. Among community members and patients, the most frequently discussed considerations were the personal impact of GT and family impact, respectively. Among physicians, the most frequently discussed topic was the characteristics of genomic services (e.g., test invasiveness); among genetic counselors, the most frequently discussed topic was evidence and recommendations. A variety of test characteristics were important in decision making about GT. High-risk patients, community members, and health care providers had different priorities. Health care professionals should be aware of differences between their own considerations about GT and those that are important to patients.

Abstract
PURPOSE Given the rapid pace of genetic and genomic research and technology development, public engagement on scientific issues may be mutually beneficial to the research community and the general public. The public may benefit from a greater understanding of concepts and new applications, and researchers can build awareness of public knowledge, perceptions, and potential concerns about genomic research and applications. METHODS We developed and piloted a public engagement program called Genome Diner to facilitate dialog between genetic/genomic researchers (n = 40) and middle school students (n = 76) and their parents (n = 83) from the local community. Program impact was assessed through pre- and post-Diner surveys for each group. RESULTS After participation in Genome Diner, researchers' views were positively affected regarding the (adult) public's level of understanding of genetic concepts, beliefs about relevance of research, and the importance of researcher-community interaction. CONCLUSION Through an interactive discussion with students and parents, researchers gained valuable insight into public perspectives about genome research. The engagement format of the Genome Diner program presents a novel method of fostering trust and relationships between the two groups and to inform both the public and the researchers, whose work may depend on public opinion and participation.

Abstract
BACKGROUND Despite international concern about unregulated predictive genetic testing, there are surprisingly few data on both the determinants of community interest in such testing and its psychosocial impact. METHOD A large population-based public survey with community-dwelling adults (n=1046) ascertained through random digit dialling. Attitudes were assessed by structured interviews. RESULTS The study found strong interest in predictive genetic testing for a reported susceptibility to depression. Once the benefits and disadvantages of such testing had been considered, there was significantly greater interest in seeking such a test through a doctor (63%) compared to direct-to-consumer (DTC; 40%) (p<0.001). Personal history of mental illness [odds ratio (OR) 2.58, p<0.001], self-estimation of being at higher than average risk for depression (OR 1.92, p<0.001), belief that a genetic component would increase rather than decrease stigma (OR 1.62, p<0.001), and endorsement of benefits of genetic testing (OR 3.47, p<0.001) significantly predicted interest in having such a test. CONCLUSIONS Despite finding attitudes that genetic links to mental illness would increase rather than decrease stigma, we found strong community acceptance of depression risk genotyping, even though a predisposition to depression may only manifest upon exposure to stressful life events. Our results suggest that there will be a strong demand for predictive genetic testing.

Wijdenes-Pijl M, Dondorp WJ, Timmermans DRM, Cornel MC, Henneman L. Lay perceptions of predictive testing for diabetes based on DNA test results versus family history assessment: a focus group study. BMC Public Health 2011; 11:535. [PMID: 21729316 PMCID: PMC3155914 DOI: 10.1186/1471-2458-11-535] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2011] [Accepted: 07/05/2011] [Indexed: 01/22/2023] Open
Abstract
BACKGROUND This study assessed lay perceptions of issues related to predictive genetic testing for multifactorial diseases. These perceived issues may differ from the "classic" issues, e.g. autonomy, discrimination, and psychological harm that are considered important in predictive testing for monogenic disorders. In this study, type 2 diabetes was used as an example, and perceptions with regard to predictive testing based on DNA test results and family history assessment were compared. METHODS Eight focus group interviews were held with 45 individuals aged 35-70 years with (n = 3) and without (n = 1) a family history of diabetes, mixed groups of these two (n = 2), and diabetes patients (n = 2). All interviews were transcribed and analysed using Atlas-ti. RESULTS Most participants believed in the ability of a predictive test to identify people at risk for diabetes and to motivate preventive behaviour. Different reasons underlying motivation were considered when comparing DNA test results and a family history risk assessment. A perceived drawback of DNA testing was that diabetes was considered not severe enough for this type of risk assessment. In addition, diabetes family history assessment was not considered useful by some participants, since there are also other risk factors involved, not everyone has a diabetes family history or knows their family history, and it might have a negative influence on family relations. Respect for autonomy of individuals was emphasized more with regard to DNA testing than family history assessment. Other issues such as psychological harm, discrimination, and privacy were only briefly mentioned for both tests. CONCLUSION The results suggest that most participants believe a predictive genetic test could be used in the prevention of multifactorial disorders, such as diabetes, but indicate points to consider before both these tests are applied. These considerations differ with regard to the method of assessment (DNA test or obtaining family history) and also differ from monogenic disorders.
