Abstract
This manuscript describes the ways in which genetic counseling has evolved since John Pearson and Sheldon Reed first promoted "a genetic education" in the 1950s as a voluntary, non-directive clinical tool for permitting individual decision making. It reviews how the emergence of Huntington's disease (HD) registries and patient support organizations, genetic testing, and the discovery of a disease-causing CAG repeat expansion changed the contours of genetic counseling for families with HD. It also reviews the guidelines, outcomes, ethical and laboratory challenges, and uptake of predictive, prenatal, and preimplantation testing, and it casts a vision for how clinicians can better make use of genetic counseling to reach a broader pool of families that may be affected by HD and to ensure that genetic counseling is associated with the best levels of care. © 2016 Wiley Periodicals, Inc.

Abstract
OBJECTIVES The purpose of this study was to explore the effect of information framing on parental decisions about resuscitation of extremely premature infants. Secondary outcomes focused on elucidating the impact of other variables on treatment choices and determining whether those effects would take precedence over any framing effects. METHODS This confidential survey study was administered to adult volunteers via the Internet. The surveys depicted a hypothetical vignette of a threatened delivery at gestational age of 23 weeks, with prognostic outcome information framed as either survival with lack of disability (positive frame) or chance of dying and likelihood of disability among survivors (negative frame). Participants were randomly assigned to receive either the positively or negatively framed vignette. They were then asked to choose whether they would prefer resuscitation or comfort care. After completing the survey vignette, participants were directed to a questionnaire designed to test the secondary hypothesis and to explore possible factors associated with treatment decisions. RESULTS A total of 146 subjects received prognostic information framed as survival data and 146 subjects received prognostic information framed as mortality data. Overall, 24% of the sample population chose comfort care and 76% chose resuscitation. A strong trend was detected toward a framing effect on treatment preference; respondents for whom prognosis was framed as survival data were more likely to elect resuscitation. This framing effect was significant in a multivariate analysis controlling for religiousness, parental status, and beliefs regarding the sanctity of life. Of these covariates, only religiousness modified susceptibility to framing; participants who were not highly religious were significantly more likely to be influenced to opt for resuscitation by the positive frame than were participants who were highly religious. CONCLUSIONS Framing bias may compromise efforts to approach prenatal counseling in a nondirective manner. This is especially true for subsets of participants who are not highly religious.

Abstract
Genetic testing is becoming a much more common practice in medicine today. This presents a unique set of challenges for medical professionals in virtually all specialties. The practical aspects of determining which test to order, and in interpreting the result accurately in the context of the family history, can be difficult. Additionally, the ethical conundrums that frequently present themselves when genetic risk assessment and/or genetic testing is being considered can be daunting. These challenges present real concerns for medical professionals and patients alike. Included in this article is a review of some of the practical and ethical complexities associated with genetic testing. Pretest and posttest genetic counseling is also emphasized as an important and essential process in today's medical practice.

Abstract
Disclosure of the results of a positive genetic mutation to offspring can be challenging. The purpose of this study was to investigate the content and process of disclosure from BRCA1/2 carriers to their offspring. A semi-structured questionnaire focused on the disclosure processes between parent and offspring. Thirty-one/40 mothers with BRCA1/2 mutations completed the cross-sectional survey. Sixteen carriers (51.6%) chose to disclose their results to all of their children, thirteen carriers (41.9%) chose not to disclose their results, and two carriers (6.5%) chose to disclose to some of their children. The age of a child appeared to be the most significant contributing factor in the decision to disclose. The mean age of the offspring who learned of the positive test result was 24.3 years with most carriers advocating the ideal age range for disclosure from 19 to 25 years. There was a discrepancy between actual and potential disclosure topics between those who had disclosed and those who had not disclosed at the time of the survey. Women who disclosed their result tended to do so alone, within a week of learning their own results, equally to male and female offspring and expressed that the relationships between themselves and their children had strengthened since revealing the presence of a genetic mutation in the family. Women who had not disclosed the results of their genetic test to offspring were significantly more interested in receiving additional individual counseling, educational videos, and email newsletters that focus on disclosure of this complex and life altering information compared to those who had already disclosed. Disclosure of BRCA1/2 results is determined primarily by age of offspring, is usually done by women alone, relatively soon after receiving results and appears to enhance the relationships between mothers and offspring. Both disclosed and non-disclosed carriers demonstrated significant interest in a variety of interventions to support the disclosure process.

Abstract
As genetic testing becomes more commonplace, medicine will likely face both family and individual demands for access to, and control of, test result information. Past research has emphasized confidentiality concerns of the individual and contrasted these claims with the "need to know" by others to avoid harm. These confidentiality concerns, based on individual self-interest, are challenged by a singularly important aspect of genetic testing-familial responsibility. As patients are often motivated to obtain genetic testing by an array of "other-directed" considerations toward their own family (such as love, fiduciary responsibility, gratitude, etc.), an accounting of these concerns is warranted. Understanding the relevance of family relationships and obligations facilitates a fuller informed consent for genetic testing. Genetic counselors and geneticists engaging in genetic counseling can account for the concerns of both individuals and their families using the family covenant-a helpful, innovative model to address proactively boundaries of privacy and information sharing within the family. This model focuses on two areas of discussion: (1) the demarcation of the boundaries of confidentiality; and (2) the definition of "family." The family covenant helps genetics providers consider what information "should" be confidential, and with respect to whom.

Abstract
Phase I trials in cancer patients, although essential, are a difficult field of clinical research. A particularly challenging area for all members of the clinical research team is that concerned with information-giving and informed consent leading to patient participation in the trial. An information booklet for patients was written in an attempt to address some of those issues, with the overall aim of improving the informed consent process and influencing patient decision-making. Questions covered in the booklet include: What is a phase I trial? Who can take part? Are there any side-effects or risks involved? What if I say no? The booklet was given to patients prior to consent. On the first day of receiving treatment they were given a questionnaire to evaluate the usefulness and acceptability of the booklet. The results showed the booklet to be generally well accepted by patients and the majority of them perceived the content and volume of information to be appropriate. The booklet did support patient decision-making and the evaluation showed that the optimal time for patients to receive it was prior to the signing of a consent form. Minor amendments have been made to the booklet, which is now given routinely to all patients at the cancer centre who are considering participation in a phase I trial, and is a valuable addition to the informed consent process.

Abstract
The widespread use of a predictive genetic test for Huntington's disease (HD) since 1993 has brought to the forefront issues regarding genetic privacy. Although the possibility of anonymous genetic testing has been discussed, its use in the United States has not been described previously. We review the experiences of 11 genetics specialists with anonymous predictive testing for HD. We found that more men than women requested anonymous testing, for reasons that more often related to personal privacy than to insurance or discrimination concerns. A number of approaches to anonymity were used, and genetics specialists varied in the degree to which they were comfortable with the process. A number of legal, medical, and practical questions are raised, which will require resolution if anonymous testing is to be performed with a greater frequency in the future.

Abstract
Recent advances in molecular genetics have highlighted the potential use of genetic testing to screen for adult-onset chronic diseases. Several issues must be addressed, however, before such tests can be recommended for population-based prevention programs. These issues include the adequacy of the scientific evidence, the balance of risks and benefits, the need for counseling and informed consent, and the costs and resources required. Ongoing assessment of the screening program and quality assurance of laboratory testing are also needed. This paper considers the application of general principles for mass screening to genetic testing for susceptibility to adult-onset chronic diseases. Evaluation of proposals for genetic screening in context of these principles reveals that needed evidence is often absent, particularly with respect to the predictive value of tests, efficacy of interventions, and social consequences of testing. The principles of population screening are developed into a framework for public health policy on genetic screening that has three stages: assessment of the screening test and interventions for those who test positive, including assessment of risks and costs, policy development, and program evaluation. Essential elements are identified, including evaluation of evidence and processes for consensus development and program evaluation. The proposed framework for public health policymaking outlined in this commentary, when combined with future efforts that involve an authoritative consensus process, may be useful for the evaluation and planning of genetic screening programs aimed at reducing morbidity and mortality from adult-onset chronic diseases.

Abstract
Genetic counseling is important in any genetic testing situation in order to address the various issues related to obtaining a genetic diagnosis. Presymptomatic testing for adult-onset neurodegenerative disease, in particular, presents a complex counseling scenario. It is imperative to discuss the potential impact of test results on patients' family dynamics, insurability and employability, family planning, and future health in addition to ascertaining a complete understanding of recurrence, inheritance, and testing parameters. The Huntington disease presymptomatic testing protocol is well-defined and has been used for more than 10 years. These guidelines, which protect both patient and provider, can now be applied to other diseases as further presymptomatic testing capabilities are realized.

Abstract
Like other medical conditions, some psychiatric disorders are inherited, whereas others are not. Human genetics research is moving at a rapid pace. Genes for over 450 genetic disorders have been cloned and many disease-causing mutations have also been identified. The explosion of this new knowledge has created many new exciting opportunities in the diagnosis of these heritable disorders. The rapid pace of gene discovery will aid the identification of susceptibility genes for psychiatric disorders. Indeed, we can look forward to answers to many clinical and research questions. These are some of the gifts that the expanding field of human genetics research will continue to bring to medical science. However, as genetic tests for the detection of psychiatric disorders become available, many ethical, legal, and social implications will need to be considered. In this article, we review the principles of genetic counseling for psychiatric disorders, as well as the social and ethical dilemmas that genetic testing may bring. Although medical and scientific advances may bring many gifts, we should approach this new knowledge with caution, as one of the gifts may be a Pandora's box.

Abstract
Risk communication is an integral part of genetic counseling and testing for cancer susceptibility. This paper reviews the emerging literature on this topic. Three relevant aspects of risk communication are addressed: communication of individual risk, communication of the risks inherent in genetic testing, and family communications related to risk. These studies suggest that (a) most individuals with some family history of cancer, including those at low to moderate risk, overestimate their personal cancer risk; (b) awareness of the risks of genetic testing is limited; (c) decision making about genetic testing is influenced strongly by exaggerated perceptions of personal cancer risk and less so by perceptions of the risks of genetic testing; (d) perceptions of personal risk of cancer are resistant to standard education and counseling approaches; (e) psychologic distress and coping processes influence the processing of risk information and subsequent decision making in genetic testing; and (f) family influences play an important role in risk awareness, genetic testing decisions, and outcomes. To study these issues further, new theoretical models and measures of risk perceptions need to be developed. Both observational and experimental methods should be used to examine both the content and process of risk communication in cancer genetic counseling and testing. Emotional, familial, and sociocultural influences on the risk communication process require special attention.

Abstract
Nurses are increasingly working in new and novel situations which may be outside the realms of traditional nursing practice. Therefore when evaluating theories and models that may be utilized in these situations it may be necessary to look beyond established nursing theories and concepts. This paper therefore attempts to evaluate Prochaska & DiClemente's (1983) stages of change model for its goodness of fit when counselling people as part of the predictive testing programme for Huntington's disease. The model demonstrates that in order to provide effective communication it is important to recognize the particular stage a client is at in his/her decision-making process concerning predictive testing. The relevance of the model to generic genetic counselling in nursing practice is discussed and the importance of stage-matched nursing interventions is emphasized. The model's non-reliance on the medical model or the concept of illness means that it may also be a useful model when applied to other nursing situations.

Abstract
OBJECTIVE To describe and illustrate elements of a group counselling approach designed to enhance the communication of risk information on breast cancer (BC) to women with a family history of this disease. Breast cancer is a leading cause of female cancer death. The most important risk factor for BC is a positive family history in at least 1 first-degree relative, and approximately one-third of women with BC have a family history of the disease. Recent evidence suggests that there is a significant psychological impact associated with having a family history of BC, and this may influence the psychological adjustment and response to being counselled for personal risk. New counselling approaches are required. METHOD This paper describes a group therapy approach that incorporates principles of supportive-expressive therapy designed to address the emotional impact of being at risk for BC and to promote accuracy of perceived risk. The key elements of the intervention are described along with clinical illustrations from groups that are part of an ongoing study to develop and standardize the group therapy. CONCLUSION Qualitative data from the groups suggest that this model of therapy is both feasible and effective.

Abstract
BACKGROUND In response to the isolation of the BRCA1 gene, a breast-ovarian cancer-susceptibility gene, biotechnology companies are already marketing genetic tests to health care providers and to the public. Initial studies indicate interest in BRCA1 testing in the general public and in populations at high risk. However, the optimal strategies for educating and counseling individuals have yet to be determined. PURPOSE Our goal was to evaluate the impact of alternate strategies for pretest education and counseling on decision-making regarding BRCA1 testing among women at low to moderate risk who have a family history of breast and/or ovarian cancer. METHODS A randomized trial design was used to evaluate the effects of education only (educational approach) and education plus counseling (counseling approach), as compared with a waiting-list (control) condition (n = 400 for all groups combined). The educational approach reviewed information about personal risk factors, inheritance of cancer susceptibility, the benefits, limitations, and risks of BRCA1 testing, and cancer screening and prevention options. The counseling approach included this information, as well as a personalized discussion of experiences with cancer in the family and the potential psychological and social impact of testing. Data on knowledge of inherited cancer and BRCA1 test characteristics, perceived risk, perceived benefits, limitations and risks of BRCA1 testing, and testing intentions were collected by use of structured telephone interviews at baseline and at 1-month follow-up. Provision of a blood sample for future testing served as a proxy measure of intention to be tested (in the education and counseling arms of the study). The effects of intervention group on study outcomes were evaluated by use of hierarchical linear regression modeling and logistic regression modeling (for the blood sample outcome). All P values are for two-sided tests. RESULTS The educational and counseling approaches both led to significant increases in knowledge, relative to the control condition (P < .001 for both). The counseling approach, but not the educational approach, was superior to the control condition in producing significant increases in perceived limitations and risks of BRCA1 testing (P < .01) and decreases in perceived benefits (P < .05). However, neither approach produced changes in intentions to have BRCA1 testing. Prior to and following both education only and education plus counseling, approximately one half of the participants stated that they intended to be tested; after the session, 52% provided a blood sample. CONCLUSIONS Standard educational approaches may be equally effective as expanded counseling approaches in enhancing knowledge. Since knowledge is a key aspect of medical decision-making, standard education may be adequate in situations where genetic testing must be streamlined. On the other hand, it has been argued that optimal decision-making requires not only knowledge, but also a reasoned evaluation of the positive and negative consequences of alternate decisions. Although the counseling approach is more likely to achieve this goal, it may not diminish interest in testing, even among women at low to moderate risk. Future research should focus on the merits of these alternate approaches for subgroups of individuals with different backgrounds who are being counseled in the variety of settings where BRCA1 testing is likely to be offered.

Abstract
Adolescents who are actively requesting Huntington's predictive testing of their own accord pose a dilemma to those providing testing. In the absence of empirical evidence as regards the impact of genetic testing on minors, current policy and guidelines, based on the ethical principles of non-maleficence and respect for individual autonomy and confidentiality, generally exclude the testing of minors. It is argued that adherence to an age based exclusion criterion in Huntington's disease predictive testing protocols is out of step with trends in UK case law concerning minors' consent to medical treatment. Furthermore, contributions from developmental psychology and research into adolescents' decision making competence suggest that adolescents can make informed choices about their health and personal lives. Criteria for developing an assessment approach to such requests are put forward and the implications of a case by case evaluation of competence to consent in terms of clinicians' tolerance for uncertainty are discussed.

Abstract
The results of genetic research have a remarkable role in medicine progress. At the same time the issues of prevention, individual attitudes and behaviour have acquired more importance, not only in relation to the illness but also regarding one's health. For these reasons is important to consider this field of study and intervention as an area to face, not only from the medical point of view but also from ethical and psychological ones. If we agree on the importance of a global approach to this problem, psychosocial support, which is often considered a parallel intervention, becomes a component of genetic counselling: the focal point of the intervention becomes the person, and not only the problem. The literature of the last years is rich of studies that have deepened these themes. Some studies have been analysed and reported but it is not easy to individualise a common patrimony of knowledge. Some aspects as information, communication, risk perception and psychological consequences are presented and discussed in this paper.
