Abstract
PURPOSE Research has shown that cancer genetic risk is often not well understood by patients undergoing genetic testing and counseling. We describe the barriers to understanding genetic risk and the needs of high-risk persons and cancer survivors who have undergone genetic testing. METHODS Using data from an internet survey of adults living in the USA who responded 'yes' to having ever had a genetic test to determine cancer risk (N = 696), we conducted bivariate analyses and multivariable logistic regression models to evaluate associations between demographic, clinical, and communication-related variables by our key outcome of having vs. not having enough information about genetics and cancer to speak with family. Percentages for yes and no responses to queries about unmet informational needs were calculated. Patient satisfaction with counseling and percentage disclosure of genetic risk status to family were also calculated. RESULTS We found that a lack of resources provided by provider to inform family members and a lack of materials provided along with genetic test results were strongly associated with not having enough information about genetics and cancer (OR 4.54 95% CI 2.40-8.59 and OR 2.19 95% CI 1.16-4.14 respectively). Among participants undergoing genetic counseling, almost half reported needing more information on what genetic risk means for them and their family and how genetic testing results might impact future screening. CONCLUSION High levels of satisfaction with genetic counseling may not give a full picture of the patient-provider interaction and may miss potential unmet needs of the patient. Accessible resources and ongoing opportunities for updating family history information could reinforce knowledge about genetic risk.

Abstract
Younger-onset dementia (YOD) refers to onset before 65 years of age and may be associated with a genetic cause. Family communication surrounding any genetic risk is complex, and this process may be further complicated in a YOD context due to its effects on cognition, behaviour, and associated psychosocial consequences. This study aimed to investigate how individuals experience family communication about potential genetic risk and testing for YOD. Thematic analysis was performed on verbatim transcripts of nine semi-structured interviews undertaken with family members who attended a neurogenetics clinic due to a relative diagnosed with YOD. The interviews explored the participants’ experiences of learning that YOD might be inherited and the ensuing family communication about genetic testing. Four key themes emerged: (1) a clinical diagnostic odyssey was common and could be a motivator for genomic testing, (2) pre-existing family tension and/or disconnection was a common barrier, (3) family members’ autonomy was considered, and (4) avoidant coping strategies influenced communication. Communication regarding potential YOD genetic risk is a complicated process and may be influenced by pre-existing family dynamics, individual coping mechanisms, and a desire to promote autonomy in relatives. To promote effective risk communication, genetic counsellors should pre-emptively address family tensions that may be exacerbated in the context of genetic testing for YOD, with awareness that family strain during a preceding period of diagnostic odyssey is common. Genetic counsellors can offer psychosocial support to facilitate coping with this tension in an adaptive way. The findings also indicated the importance of extending genetic counselling support to relatives.

Abstract
Introduction The burden of non-alcoholic fatty liver disease (NAFLD) continues to disproportionately impact under-resourced communities in the U.S., particularly Mexican-origin populations. Genetic polymorphisms such as the rs738409 C/G variant in patatin-like phospholipase domain-containing 3 (PNPLA3) have been associated with higher prevalence of and progression along the NAFLD spectrum. This qualitative study conducted in the U.S. Southwest aimed to assess Mexican-origin men's experience receiving genetic testing for PNPLA3 risk carrier status. Methods Semi-structured interviews were conducted with 17 Mexican-origin men whose NAFLD status and genetic predisposition were determined as part of a previous cross-sectional study. The interview guide included questions exploring participants' insights on how genetic risk status was delivered, how the information influenced their motivation for lifestyle modification to reduce NAFLD risk, and any knowledge sharing that occurred with family members after learning of their PNPLA3 risk status. Interviews were conducted and audio recorded in English (n = 6) and Spanish (n = 11) and uploaded into NVivo software for data analysis and interpretation. Guided by the Health Belief Model, a thematic analysis approach was used to identify primary themes. Results Results highlighted men's preference for receiving this type of genetic risk information through a letter sent to their homes. General comprehension of PNPLA3 risk status was deemed high and most men stated sharing their genetic predisposition to NAFLD with their immediate family members. Participants also indicated that family and awareness of this genetic risk acted as primary motivators for implementing behavior changes (e.g., diet, physical activity) toward the prevention of more severe liver conditions. Discussion Findings from this qualitative study suggest the feasibility of communicating genetic risk for NAFLD among Mexican-origin men. Future strategies for the dissemination of genetic risk results among Mexican-origin individuals should consider familial and cultural appropriate strategies.

Abstract
BACKGROUND When a woman is diagnosed with hereditary breast or ovarian cancer, family members may be at high risk of cancers associated with BRCA1/2 gene mutation and benefit from disclosure of the genetic test result. This duty of informing relatives may be distressing, or relatives may not be properly informed. OBJECTIVE To qualitatively describe breast cancer patients' experiences communicating genetic risk of cancer to their relatives. METHODS Probands with BRCA1/2 gene mutations were recruited from an oncology institute in Istanbul, Turkey, and interviewed by telephone. Qualitative content analysis was conducted to derive central elements of the 30 women's experiences communicating genetic risk to their relatives. RESULTS Six themes were identified: response to genetic test results, reason for communication, feelings about communication, reflection after communication, results of communication, and needs. CONCLUSION Women with cancer found to have BRCA1/2 gene mutations tended to share their genetic test results within the family. The main motives for sharing test results were the desire to encourage relatives to get tested and moral and ethical convictions. Women needed explicit information regarding cancer risk and risk-reducing strategies to act upon. IMPLICATIONS FOR PRACTICE The women's feelings and reflections about the communication process were varied and suggest that personalized genetic risk communication interventions may better support women with BRCA1/2 gene mutations during and after communication with relatives. Long-term follow-up of those women is essential because of the need for informed decision on risk-reducing strategies.

Abstract
Background In hereditary breast and ovarian cancer (HBOC), family communication of genetic test results is essential for cascade genetic screening, that is, identifying and testing blood relatives of known mutation carriers to determine whether they also carry the pathogenic variant, and to propose preventive and clinical management options. However, up to 50% of blood relatives are unaware of relevant genetic information, suggesting that potential benefits of genetic testing are not communicated effectively within family networks. Technology can facilitate communication and genetic education within HBOC families. Objective The aims of this study are to develop the K-CASCADE (Korean–Cancer Predisposition Cascade Genetic Testing) cohort in Korea by expanding an infrastructure developed by the CASCADE (Cancer Predisposition Cascade Genetic Testing) Consortium in Switzerland; develop a digital health intervention to support the communication of cancer predisposition for Swiss and Korean HBOC families, based on linguistic and cultural adaptation of the Family Gene Toolkit; evaluate its efficacy on primary (family communication of genetic results and cascade testing) and secondary (psychological distress, genetic literacy, active coping, and decision making) outcomes; and explore its translatability using the reach, effectiveness, adoption, implementation, and maintenance framework. Methods The digital health intervention will be available in French, German, Italian, Korean, and English and can be accessed via the web, mobile phone, or tablet (ie, device-agnostic). K-CASCADE cohort of Korean HBOC mutation carriers and relatives will be based on the CASCADE infrastructure. Narrative data collected through individual interviews or mini focus groups from 20 to 24 HBOC family members per linguistic region and 6-10 health care providers involved in genetic services will identify the local cultures and context, and inform the content of the tailored messages. The efficacy of the digital health intervention against a comparison website will be assessed in a randomized trial with 104 HBOC mutation carriers (52 in each study arm). The translatability of the digital health intervention will be assessed using survey data collected from HBOC families and health care providers. Results Funding was received in October 2019. It is projected that data collection will be completed by January 2023 and results will be published in fall 2023. Conclusions This study addresses the continuum of translational research, from developing an international research infrastructure and adapting an existing digital health intervention to testing its efficacy in a randomized controlled trial and exploring its translatability using an established framework. Adapting existing interventions, rather than developing new ones, takes advantage of previous valid experiences without duplicating efforts. Culturally sensitive web-based interventions that enhance family communication and understanding of genetic cancer risk are timely. This collaboration creates a research infrastructure between Switzerland and Korea that can be scaled up to cover other hereditary cancer syndromes.

Abstract
BACKGROUND The genetic risk communication from proband to relatives varies from family to family, and patients often need support with the communication of genetic test results and making decisions to manage hereditary cancer risks. OBJECTIVE The aim of this study was to characterize the communication of BRCA1 or BRCA2 (BRCA1/2) genetic risk from proband to first-degree relatives (FDRs) using a social network framework. METHODS We characterized network and nonnetwork factors to explore their association with which FDRs were told about the genetic risk and whether or not relatives underwent genetic testing. Ninety-two female probands with hereditary breast and ovarian cancer who have confirmed BRCA1/2 mutations participated in the study. Communication of hereditary breast and ovarian cancer risk was assessed between 92 probands and their 417 FDRs. RESULTS Of 92 probands, 94.5% (n = 87) communicated their genetic test result to at least one of their FDRs. Of FDRs older than 18 years, 19.9% (n = 72) have genetic testing. Emotional closeness, educational level of the proband, and relative's age were significantly associated with communicating test results with FDRs. CONCLUSION Communication of genetic risk with the FDRs after having a BRCA1/2 gene-mutation-positive test result was high in this group of cancer patients. However, the rate of genetic testing among FDRs was low. IMPLICATIONS FOR PRACTICE Probands' educational level and age of relatives for cascade genetic screening should be considered during counseling. Interventions to support women with BRCA1/2 mutations during the communication process and their family members' engagement in testing and risk-reducing strategies are needed.

Abstract
Pathogenic germline variants in Breast Cancer 1/2 (BRCA) genes confer increased cancer risk. Understanding BRCA status/risk can enable family cascade screening and improve cancer outcomes. However, more than half of the families do not communicate family cancer history/BRCA status, and cancer outcomes differ according to parent of origin (i.e., maternally vs. paternally inherited pathogenic variant). We aimed to explore communication patterns around family cancer history/BRCA risk according to parent of origin. We analyzed qualitative interviews (n = 97) using template analysis and employed the Theory of Planned Behavior (TPB) to identify interventions to improve communication. Interviews revealed sub-codes of ‘male stoicism and ‘paternal guilt’ that impede family communication (template code: gender scripting). Conversely, ‘fatherly protection’ and ‘female camaraderie’ promote communication of risk. The template code ‘dysfunctional family communication’ was contextualized by several sub-codes (‘harmful negligence’, ‘intra-family ignorance’ and ‘active withdrawal of support’) emerging from interview data. Sub-codes ‘medical misconceptions’ and ‘medical minimizing’ deepened our understanding of the template code ‘medical biases’. Importantly, sub-codes of ‘informed physicians’ and ‘trust in healthcare’ mitigated bias. Mapping findings to the TPB identified variables to tailor interventions aimed at enhancing family communication of risk and promoting cascade screening. In conclusion, these data provide empirical evidence of the human factors impeding communication of family BRCA risk. Tailored, theory-informed interventions merit consideration for overcoming blocked communication and improving cascade screening uptake.

Abstract
Screening programmes for BRCA1/2 Jewish Founder mutations (JFM) in the Jewish community have been advocated internationally. Implementation of these programmes could decrease morbidity and mortality of BRCA1/2 JFM carriers through the uptake of cancer screening strategies and risk-reducing surgery. An online programme offered to the Sydney Jewish community that delivers pre-test information and collects consent for BRCA1/2 JFM testing via a website is currently being evaluated (JeneScreen). Forty-three participants from JeneScreen were invited to participate in a sub-study, of semi-structured pre- and post-result telephone interviews. Eleven participants consented to the sub-study. The interviews explored their experiences regarding the online model of obtaining pre-test genetic information, giving consent and receiving results. Inductive thematic analysis was carried out on the interviews. Overarching themes identified include (1) embracing online testing, (2) the online pre-test experience, (3) the result notification experience, (4) concerns associated with online testing and (5) testing as a responsibility. Overall, participants were highly satisfied with online BRCA1/2 JFM testing, an indication that the a website for pre-test information provision is an acceptable alternative to in-person genetic counselling for BRCA1/2 JFM screening and represents a feasible model for future community screening efforts.

Attitudes of 1379 Dutch patients, relatives, and members of the general population. J Genet Couns 2019; 29:786-799.

Abstract
The uptake of predictive DNA testing in families with a hereditary disease is <50%. Current practice often relies on the proband to inform relatives about the possibility of predictive DNA testing, but not all relatives are informed adequately. To enable informed decision-making concerning predictive DNA testing, the approach used to inform at-risk relatives needs to be optimized. This study investigated the preferences of patients, relatives, and the general population from the Netherlands on how to inform relatives at risk of autosomal dominant diseases. Online surveys were sent to people with autosomal dominant neuro-, onco-, or cardiogenetic diseases and their relatives via patient organizations (n = 379), and to members of the general population via a commercial panel (n = 1,000). Attitudes of the patient and population samples generally corresponded. A majority believed that initially only first-degree relatives should be informed, following the principles of a cascade screening approach. Most participants also thought that probands and healthcare professionals (HCPs) should be involved in informing relatives, and a large proportion believed that HCPs should contact relatives directly in cases where patients are unwilling to inform, both for untreatable and treatable conditions. Participants from the patient sample were of the opinion that HCPs should actively offer support. Our findings show that both patients and HCPs should be involved in informing at-risk relatives of autosomal dominant diseases and suggest that relatives' 'right to know' was considered a dominant issue by the majority of participants. Further research is needed on how to increase proactive support in informing of at-risk relatives.

Informing relatives at risk of inherited cardiac conditions: experiences and attitudes of healthcare professionals and counselees. Eur J Hum Genet 2019; 27:1341-1350.

Abstract
Inherited cardiac conditions (ICCs) can lead to sudden cardiac death at young age, even without previous symptoms, yet often remain undetected. To prevent sudden cardiac death, cardiac monitoring and/or predictive DNA testing is advised for at-risk relatives. Probands in whom a causal variant is detected are asked to inform their relatives about the possibility of testing, often supported by a family letter. This qualitative study investigates experiences with and attitudes toward this family-mediated approach in ICCs and explores whether and how improvements can be made. Two online focus groups were conducted with 28 healthcare professionals (HCPs) from various disciplines, as were 25 face-to-face semi-structured interviews with counselees (10 probands; 15 relatives). Data were analysed by two researchers independently using a thematic approach. Participants, both HCPs and counselees, preferred that probands inform relatives about genetic risks in ICCs, but both groups struggled with the dependency on and burden on probands to inform their relatives. To overcome this, HCPs do see a more active role for themselves in informing relatives, but prefer uniformity in procedures in order to maintain their workload. Counselees, on the other hand, prefer a tailored information provision strategy adjusted to family dynamics and the personality characteristics of relatives. In conclusion, although it is generally preferred that probands inform relatives themselves, a more active role of HCPs could be considered to overcome the dependency and burden on probands. Further research is needed to study how HCPs can engage more actively in informing at-risk relatives in current clinical genetic practise.

Abstract
Following the identification in a proband of a germline BRCA1/BRCA2 mutation in hereditary breast-ovarian cancer (HBOC) or a DNA mismatch repair gene mutation in Lynch syndrome (LS) he or she will be asked to inform at-risk family members about the option for presymptomatic DNA testing. However, in clinical practice multiple factors may complicate the process of information sharing. We critically evaluated studies on the uptake of presymptomatic genetic testing in both syndromes. A search of relevant MeSH terms and key words in PubMed, Embase and PsycINFO yielded 795 articles published between 2001 and 2017. Thirty of these publications included outcome measures relevant for the current study. Based on information provided by the proband (15 studies) the uptake of presymptomatic genetic testing ranged from 15 to 57% in HBOC, while one study in LS kindreds reported an uptake of 70%. Based on information provided by genetics centres (the remaining 15 studies) the uptake ranged from 21 to 44% in HBOC and from 41 to 94% in LS. However, when genetics centres contacted relatives directly a substantial number of additional family members could be tested. Proband-mediated provision of information to at-risk relatives is a standard procedure in hereditary breast-ovarian cancer and Lynch syndrome. However, the resulting uptake of presymptomatic testing is disappointing-an issue that is now urgent due to the increased use of genetic testing in clinical oncology. We propose that additional strategies should be introduced including the geneticist directly contacting relatives. The outcomes of these strategies should be carefully monitored and evaluated.

Abstract
OBJECTIVE In hereditary and familial cancer, counselees are requested to inform their at-risk relatives. We developed an intervention to support counselees in this task. METHODS A randomized controlled trial was conducted aimed at improving cancer genetic counselees' i) knowledge, ii) motivation to disclose information, and ii) self-efficacy in this regard. Eligible participants were randomized to telephonic counseling (n = 148), or standard care (n = 157) and assessed at baseline, 1 week post-intervention, and 4 months after study enrolment. RESULTS No between-group differences were found in participants' knowledge, motivation, and self-efficacy. Knowledge concerning which second-degree relatives to inform was lower compared to first-degree relatives. About 60% of the participants was of the opinion that they needed to inform more relatives than stated in their summary letter and only about 50% were correctly aware of which information to disclose. Of note, at baseline, almost 80% of the participants had already correctly informed their at-risk relatives. CONCLUSIONS Since, unexpectedly, counselees already informed most of their relatives before the intervention was offered, efficacy of the intervention could not convincingly be determined. Counselees' knowledge about whom to inform about what is suboptimal. PRACTICE IMPLICATIONS Future interventions should target a more homogeneous sample and address counselees' understanding and recall.

Abstract
INTRODUCTION Women facing complex and uncertain situations such as cancer in their families may seek information from a variety of sources to gain knowledge about cancer risk and reduce uncertainty. We describe and assess the relative importance of information sources about familial breast cancer at the individual, family, and healthcare provider levels influencing women's reporting they had enough information to speak with daughters about breast cancer. This outcome we refer to as being informed about breast cancer. MATERIALS AND METHODS Sister Study participants, a cohort of women with a family history of breast cancer, were surveyed on family cancer history, family communication, social support, and interactions with healthcare providers (n = 11,766). Adjusted percentages and 95% confidence intervals for being informed about breast cancer versus not being informed were computed for individual-, family-, and provider-level characteristics in three steps using multivariate logistic regression models. RESULTS We found 65% of women reported being informed about breast cancer while 35% did not. Having a trusted person with whom to discuss cancer concerns, having a lower versus higher perceived risk of breast cancer, having undergone genetic counseling, and being satisfied with physician discussions about breast cancer in their families were predictors of being informed about breast cancer. CONCLUSIONS Although acquiring objective risk information, such as through genetic counseling, may contribute to a basic level of understanding, communication with providers and within other trusted relationships appears to be an essential component in women's reporting they had all the information they need to talk with their daughters about breast cancer.

Abstract
PURPOSE/OBJECTIVES To gain insight into parental decision making regarding the disclosure or nondisclosure of a mutation-positive BRCA1/2 test result to minors.
. RESEARCH APPROACH A qualitative study based on Heidegger hermeneutic phenomenology was undertaken to explore the lived experience of parental decision making regarding high-risk BRCA1/2 disclosure.
. SETTING The study's recruitment site was a western Canadian hereditary breast and ovarian cancer clinic.
. PARTICIPANTS Fifteen female mutation-positive BRCA1/2 carriers who had at least one child aged 6-18 years.
. METHODOLOGIC APPROACH The use of a demographic questionnaire, semistructured interviews, and conversation summaries were employed to gain an understanding of participants' lived experience. van Manen's selective approach was used to conduct a thematic analysis.
. FINDINGS Collectively, parents wanted clinicians to discuss implications of disclosing and not disclosing a mutation-positive BRCA1/2 test result to minors in greater detail. The findings were categorized under the following emergent themes. CONCLUSIONS Participants' stories identified the need for auxiliary support pertaining to the decision-making process and suggested ways in which parental support may be coordinated.
. INTERPRETATION Oncology nurses with advanced genetics training should assist mutation-positive BRCA1/2 carriers in meeting their genetic risk information needs; this requires nurses to stay informed about a multitude of issues that affect this population of patients.

Abstract
Cancer genetic counselees receive individualized information regarding heightened risks and medical recommendations which is also relevant for their at-risk relatives. Unfortunately, counselees often insufficiently inform these relatives. We designed an intervention aimed at improving counselees’ knowledge regarding which at-risk relatives to inform and what information to disclose, their motivation to disclose, and their self-efficacy. The intervention, offered by telephone by trained psychosocial workers, is based on the principles of Motivational Interviewing. Phase 1 of the intervention covers agenda setting, exploration, and evaluation, and phase 2 includes information provision, enhancing motivation and self-efficacy, and brainstorming for solutions to disseminate information within the family. Fidelity and acceptability of the intervention were assessed using recordings of intervention sessions and by counselee self-report. A total of 144 counselees participated. Psychosocial workers (n = 5) delivered the intervention largely as intended. Counselees highly appreciated the content of the intervention and the psychosocial workers who delivered the intervention. In the sessions, psychosocial workers provided additional and/or corrective information, and brainstorming for solutions was performed in 70 %. These results indicate that this intervention is feasible and warrants testing in clinical practice. For this, a randomized controlled trial is currently in progress to test the intervention’s efficacy.

Abstract
BACKGROUND There exist no recommendations as to how aggregate research results should best be disclosed to long-term cohort participants. OBJECTIVE To study the impact of cohort results disclosure documents of various kinds on participants' satisfaction. DESIGN Randomized study with a 2x2 factorial design. SETTING AND PARTICIPANTS The GENEPSO-PS cohort is used to study the psychosocial characteristics and preventive behaviour of both BRCA1/2 carriers and non-carriers; 235 participants wishing to receive 'information about the survey results' answered a self-administered questionnaire. INTERVENTIONS The impact of providing the following items in addition to a leaflet about aggregate psychosocial research results was investigated (i) an up-to-date medical information sheet about BRCA1/2 genetic topics, (ii) a photograph with the names of the researchers. MAIN OUTCOME MEASURES Satisfaction profiles drawn up using cluster analysis methods. RESULTS Providing additional medical and/or research team information had no significant effect on satisfaction. The patients attributed to the 'poorly satisfied' group (n = 60, 25.5%) differed significantly from those in the 'highly satisfied' group (n = 51, 21.7%): they were younger [odds ratio (OR) = 0.96, 95% confidence interval (0.92-0.99), P = 0.028], less often had a daughter [OR = 4.87 (1.80-13.20), P = 0.002], had reached a higher educational level [OR = 2.94 (1.24-6.95), P = 0.014] and more frequently carried a BRCA1/2 mutation [OR = 2.73 (1.20-6.23), P = 0.017]. CONCLUSIONS This original approach to disclosing research results to cohort participants was welcomed by most of the participants, but less by the more educated and by BRCA1/2 carriers. Although an easily understandable document is necessary, it might also be worth providing some participants with more in-depth information.

Abstract
Encouraging family communication is an integral component of genetic counseling; therefore, we sought to identify factors impacting communication to family members at risk for Hypertrophic Cardiomyopathy (HCM). Participants (N = 383) completed an online survey assessing: 1) demographics (gender, genetic test results, HCM family history, and disease severity); 2) illness representations; 3) family functioning and cohesiveness; 4) coping styles; 5) comprehension of HCM autosomal dominant inheritance; and 6) communication of HCM risk information to at-risk relatives. Participants were a national sample of individuals with HCM, recruited through the Hypertrophic Cardiomyopathy Association. Data from 183 participants were analyzed using a logistic regression analysis, with family communication as a dichotomous dependent variable. We found that female gender and higher comprehension of autosomal dominant inheritance were significant predictors of participants' communication of HCM risk information to all their siblings and children. Our results suggest that utilizing interventions that promote patient comprehension (e.g., a teaching-focused model of genetic counseling) are important and may positively impact family communication within families with HCM.

Abstract
BACKGROUND Genetic counseling for hereditary breast or colon cancer has implications for both counselees and their relatives. Although counselees are encouraged by genetic counselors to disclose genetic cancer risk information, they do not always share this information with their at-risk relatives. Reasons for not informing relatives may be generally categorized as a lack of knowledge, motivation and/or self-efficacy. Presented here is the protocol of a randomized controlled trial that aims to establish the effectiveness of an intervention focused on supporting counselees in their disclosure of genetic cancer information to their relatives. METHODS/DESIGN A multicenter randomized controlled trial with parallel group design will be used to compare the effects of an additional telephone counseling session performed by psychosocial workers to enhance the disclosure of genetic cancer information to at-risk relatives (intervention group) with a control group of standard care. Consecutive index patients with relatives at risk for hereditary or familial breast and/or ovarian cancer or colon cancer, are randomly assigned (block size: 8; 1:1 allocation ratio) to the intervention (n = 132) or control group (n = 132, standard care). Primary outcomes are counselees' knowledge, motivation and self-efficacy regarding informing their relatives. DISCUSSION This intervention may prove important in supporting counselees to disclose hereditary and/or familial cancer risk information to at-risk relatives and may enable more at-risk relatives to make a well-informed decision regarding genetic services and/or screening. TRIAL REGISTRATION This trial is registered in the Netherlands National Trial Register (NTR) with trial ID number NTR3745.

Abstract
This review describes the characteristics of available educational tools used for BRCA1/2 genetic testing. To identify the tools, we conducted a systematic search in electronic databases, and contacted over 1000 cancer genetics professionals. This review is based on 68 tools from the USA, Canada, Australia, the UK, France and Ireland. The tools vary in format and scope depending on the genetic testing phase for which they are intended. We found that a wide diversity of educational materials are available and used for BRCA1/2 genetic testing around the world. However, a substantial number of tools fail to address important aspects of genetic testing.

Abstract
PURPOSE The Kathleen Cuningham Foundation Consortium for Research into Familial Aspects of Breast Cancer (kConFab) is a large-scale research study that notifies participants when new, personally relevant, information is discovered. In 2009, the (kConFab) instituted an intensive notification process to ensure at-risk individuals were effectively notified. This study (i) evaluated the impact of intensive notification on genetic testing uptake; (ii) identified those most likely to undergo testing postnotification; and (iii) identified those most likely to acknowledge that they had been notified. METHODS Clinical/demographic data were retrieved from the (kConFab) database. Logistic regression analyses were conducted to identify potential predictors of testing uptake and notification acknowledgment using IBM SPSS. RESULTS A total of 155 of 1,812 individuals underwent testing after standard notification (8.6%). In comparison, 23/291 individuals (7.9%) notified using the "intensive" approach underwent testing (χ(2) = 0.14; P = 0.71). After controlling for notification process, females and participants with a previous cancer were most likely to have undergone testing (P < 0.006). Older individuals (50+ years) were most likely to acknowledge they had been notified (P = 0.038). CONCLUSION Increasing the intensity of participant follow-up did not increase genetic testing uptake. The challenge to effectively notify participants, and increase the proportion whose risk is managed clinically, remains, particularly for males and individuals unaffected by cancer.Genet Med 2013:15(3):187-194.

Abstract
This research examined the lay public's beliefs about genes and health that might be labeled deterministic. The goals of this research were to sort through the divergent and contested meanings of genetic determinism in an effort to suggest directions for public health genomic communication. A survey conducted in community-based settings of 717 participants included 267 who self-reported race as African American and 450 who self-reported race as Caucasian American. The survey results revealed that the structure of genetic determinism included 2 belief sets. One set aligned with perceived threat, encompassing susceptibility and severity beliefs linked to genes and health. The other set represents beliefs about biological essentialism linked to the role of genes for health. These concepts were found to be modestly positively related. Threat beliefs predicted perceived control over genes. Public health efforts to communicate about genes and health should consider effects of these messages for (a) perceived threat relating to susceptibility and severity and (b) perceptions of disease essentialism. Perceived threat may enhance motivation to act in health protective ways, whereas disease essentialist beliefs may contribute to a loss of motivation associated with control over health.
