BRCA1/2 testing in hereditary breast and ovarian cancer families III: risk perception and screening.

This study aimed to ascertain whether cancer risk perception changed following the offer and subsequent receipt of BRCA1/2 results and to evaluate breast and ovarian screening practices in testers and non-testers. Members of thirteen HBOC families were offered BRCA1/2 testing for a known family mutation. Perceived risk for developing breast cancer, ovarian cancer or for carrying the familial BRCA1/2 mutation, was assessed at baseline and again at 6-9 months following the receipt of test results. Breast and ovarian cancer screening data were obtained at both time-points. A total of 138 women participated and 120 (87%) chose to be tested for a known familial mutation. Twenty-eight women (24%) were identified as carriers and their perceived ovarian cancer risk and their perception of being a mutation carrier increased (P = 0.01 for both). Those testing negatives had a significant decrease in all dimensions of risk perception (P < 0.01). Regression analysis showed test results to be strong predictors of follow-up risk perception (P = 0.001), however, they were not predictors of screening practices at follow-up. Testers were more likely to have completed a clinical breast exam following testing than decliners. Mammography was positively associated with baseline adherence, age, and intrusive thoughts. Ovarian cancer worries only predicted pelvic ultrasound screening post-testing. Baseline practices and psychological factors appear to be stronger predictors of health behavior than test results.

The relationship of nondirectiveness to genetic counseling: report of a workshop at the 2003 NSGC Annual Education Conference.

Nondirectiveness has been a guiding principle for genetic counseling since the founding of the profession. However, its efficacy and appropriateness in this role have been frequently questioned. A workshop at the 2003 Annual Education Conference of the National Society of Genetic Counselors provided audience participation in a discussion of these issues. Participants presented arguments for and against nondirectiveness as a central ethos. They described complex personal transitions in adapting what they had learned about nondirectiveness during training to the realities of the workplace. There was support for flexible approaches to genetic counseling, with varying adherence to nondirectiveness, based on client and family needs and values, clinical circumstances, and desired counseling outcomes. The discussion supports the use of clinical experience, outcomes research, and the experience of other professions to move beyond nondirectiveness and more accurately identify the theoretical bases that underlie genetic counseling in the variety of circumstances in which it is currently practiced.

A new definition of Genetic Counseling: National Society of Genetic Counselors' Task Force report.

The Genetic Counseling Definition Task Force of the National Society of Genetic Counselors (NSGC) developed the following definition of genetic counseling that was approved by the NSGC Board of Directors: Genetic counseling is the process of helping people understand and adapt to the medical, psychological and familial implications of genetic contributions to disease. This process integrates the following: Interpretation of family and medical histories to assess the chance of disease occurrence or recurrence. Education about inheritance, testing, management, prevention, resources and research. Counseling to promote informed choices and adaptation to the risk or condition. The definition was approved after a peer review process with input from the NSGC membership, genetic professional organizations, the NSGC legal counsel, and leaders of several national genetic advocacy groups.

Genetic susceptibility testing from a stress and coping perspective.

Four theories of health behavior and of stress and coping are reviewed for their ability to illuminate interest in uptake and outcomes of genetic testing for adult-onset diseases. These theories are the Health Belief Model, the Theory of Planned Behavior (TPB), the Common Sense Model of Self-regulation (CSM), and the Transactional Model of Stress and Coping (TMSC). Basic concepts of each theory are discussed, followed by evidence from the literature supporting the relevance of these concepts to the understanding of genetic testing for four adult-onset diseases: Huntington's disease, Alzheimer's disease, hereditary breast/ovarian cancer, and hereditary colorectal cancer. Emphasis is placed on the finding that a decision to undergo genetic testing may be considered as a way to cope with both the cognitive and affective concerns that arise from living at increased risk of developing a disease in the future. The potential value of genetic testing for reducing uncertainty about and gaining a sense of control over one's risk of developing a chronic disease is highlighted. We argue that theories which focus on stress and coping provide a useful framework for future studies of genetic testing decisions for adult-onset disease risk.

BRCA1/2 testing in hereditary breast and ovarian cancer families II: impact on relationships.

Members of hereditary breast and ovarian cancer (HBOC) families often express concern during genetic counseling about the impact of BRCA1/2 testing on close relatives. Yet whether there are likely to be adverse effects of either the decision to undergo genetic testing or the results of testing on family relationships is unknown. One purpose of this study was to assess the impact on close family relationships. Within a randomized trial of breast cancer genetic counseling methods, members of 13 HBOC families were offered BRCA1/2 testing for a known family mutation. The Family Relationship Index (FRI) of the Family Environment Scale (FES) was used to measure perceived family cohesion, conflict, and expressiveness at baseline and again 6-9 months following the receipt of test results, or at the equivalent time for those who declined testing. Participants (n = 212) completed baseline and follow-up questionnaires. Comparisons were made between testers and non-testers as well as between those who tested positive and negative for the family mutation. One hundred eighty-one participants elected to undergo genetic testing (85%) and 47 (26%) were identified to have a mutation. After adjusting for baseline family relationship scores, counseling intervention, gender and marital status, non-testers reported a greater increase in expressiveness (P = 0.006) and cohesion (P = 0.04) than testers. Individuals who tested positive reported a decrease in expressiveness (P = 0.07), although as a trend. Regardless of test decision or test result, those who were randomized to a client-centered counseling intervention reported a decrease in conflict (P = 0.006). Overall, study results suggest that undergoing genetic testing and learning ones BRCA1/2 status may affect family relationships. Those individuals who declined testing reported feeling closer to family members and more encouraged to express emotions to other family members demonstrating potential benefit from the offer of testing. Since those who tested positive reported feeling less encouraged to express their emotions within the family, we recommend helping clients to identify others with whom they feel comfortable sharing their thoughts and feelings about their positive gene status and increased cancer risk.

BRCA1/2 testing in hereditary breast and ovarian cancer families: effectiveness of problem-solving training as a counseling intervention.

It remains uncertain whether members of hereditary breast and ovarian cancer (HBOC) families experience psychological distress with genetic testing and whether pre-test counseling can have a moderating effect on client well-being. One purpose of this study was to assess change in psychological well-being from baseline to 6-9 months follow-up and the effect of a problem-solving training (PST) intervention on psychological well-being. Two hundred and twelve members of 13 HBOC families were offered BRCA1/2 testing for a previously identified family mutation. Participants received education and were randomized to one of two counseling interventions; PST or client-centered counseling. Psychological well-being was assessed at baseline and again at 6-9 months following the receipt of test results, or at the equivalent time for those participants who chose not to undergo testing. Well-being was assessed using measures of depressive symptoms (CESD), intrusive thoughts (IES), cancer worries, and self-esteem. Comparisons were made between those who chose testing and those who did not as well as between those who received positive and negative test results. One hundred eighty one participants elected to undergo genetic testing (85%) and 47 of these (26%) were identified as BRCA1/2 mutation carriers. Breast and ovarian cancer worries decreased significantly (p = 0.007 and 0.008, respectively) in those who tested negative while there was no appreciable change in psychological well-being from baseline to follow-up in either those who tested positive or in non-testers. Among all participants, particularly testers, those randomized to PST had a greater reduction in depressive symptoms than those randomized to client-centered counseling (p < 0.05 and p = 0.02, respectively). Regardless of the decision to test, individuals with a personal history of cancer (n = 22) were more likely to have an increase in breast cancer worries compared to those who had never been diagnosed with cancer (p < 0.001). Results suggest that a problem-solving counseling intervention may help to enhance psychological well-being following testing and that a personal history of cancer may increase psychological distress associated with genetic testing.

Genetics and alcoholism among at-risk relatives II: interest and concerns about hypothetical genetic testing for alcoholism risk.

One purpose of this study was to examine hypothetical interest in genetic predisposition testing for alcoholism among at-risk relatives. Qualitative interviews and several quantitative tools were administered to 27 individuals who had at least one first-degree relative affected by alcoholism. Data analysis revealed that participants' interest in genetic testing for susceptibility to alcoholism was moderate. Lower educational level and a stronger belief in 'others' influencing health were related to participants' having a stronger interest in genetic testing. Participants' concerns about future use of genetic testing ranged from doubts about its usefulness in affecting behavior to apprehension regarding detrimental societal effects such as breaches in confidentiality and fear of being labeled an 'alcoholic.' Younger age and stronger interest in genetic testing were associated with deterministic or fatalistic beliefs, while drinking behaviors, gender, and other demographics were not. Participants questioned the utility of this type of testing. Their interest in testing and concerns about its hypothetical use may prove important for at-risk relatives who may face decisions about genetic testing in the future. Data from this study can provide direction for researchers and health care providers as genetic testing for this and other behavioral conditions emerges. Scientists and the public should address the social concerns expressed by participants, including the fear of labeling. Also, we can begin to anticipate characteristics common in those who may have fatalistic responses, and who may possibly make adverse behavior choices, to results from alcoholism susceptibility testing.

Genetics and alcoholism among at-risk relatives I: perceptions of cause, risk, and control.

Genetic factors influence a person's risk for developing alcoholism. In other common disorders with a genetic component, a belief in a genetic cause can lead to less perceived control or fatalism among those at risk that may adversely affect undertaking health-promoting behaviors. This study explores beliefs about the cause of alcoholism and risk perception among individuals with affected relatives. In-depth interviews including both open-ended questions and several quantitative measures were conducted with participants to explore the relationships between causal beliefs and perceptions of personal risk and control. Twenty-seven individuals with at least one first-degree relative affected with alcoholism participated. Transcript analysis of interviews revealed that all participants attribute multiple factors to the cause of alcoholism in their families, often as a combination of biological, genetic, environmental factors, and personal characteristics. Many perceived themselves as being 'at-risk,' and this concern often stemmed from a belief in a genetic or biological cause of alcoholism. However, participants also had a strong sense of personal control, rooted in beliefs about environmental causes or personal characteristics influencing alcoholism risk. A participant's strong belief in a genetic cause was associated with a significantly increased risk perception, but not a fatalistic outlook towards developing alcoholism.

Ethical issues in psychiatric genetics research: points to consider.

RATIONALE: Psychiatric genetics research warrants ethical consideration because of the complex nature of conducting research among affected families. When researchers identify compelling reasons to offer susceptibility data to participants, they face challenges to identify an infrastructure to convey information and means to ensure that undue research risks are not encountered. OBJECTIVES: To outline ethical issues in conducting research in psychiatric genetics with the aim of considering how the identification of susceptibility genes for psychiatric disorders may shape future research; to provide points to consider for conducting psychiatric genetics research with the anticipation of offering susceptibility data to participants. METHODS: Ethical issues that arise in psychiatric genetics research conducted with affected families are discussed along with reasons susceptibility data may be offered to participants in the future. RESULTS: We suggest that all researchers, even those who have no intention of offering susceptibility genetic results, consider how advances in knowledge might affect the provision of research findings. CONCLUSIONS: Existing ethical issues are likely to become even more pressing as susceptibility genes are identified for major psychiatric disorders. It behooves researchers, mental health professionals, and geneticists to consider how to use our growing scientific knowledge to best help participants in ways that anticipate and prevent, rather than respond to, ethical conflicts.

Issues surrounding prenatal genetic testing for achondroplasia.

OBJECTIVES: Mutations in the gene encoding fibroblast growth factor receptor 3 cause achondroplasia, the most prevalent form of dwarfism. Since the discovery of the mutations and gene in 1994, commercial testing has been available for use in prenatal diagnosis. This study sought to determine the awareness of, interest in and use of prenatal genetic testing for achondroplasia. METHODS: Surveys were collected from both individuals affected with achondroplasia (n = 189) and their average statured relatives (n = 136). RESULTS: The majority of participants were aware of the prenatal genetic testing at the time they were surveyed, but less than 10% had actually used the testing. Affected individuals were much more interested in using the testing if they became pregnant (62%) than were their relatives (28%). The groups were remarkably similar in their interest in using the testing to identify the lethal, homozygous form of achondroplasia and in their unwillingness to consider termination of pregnancies based on a diagnosis of either achondroplasia or average stature. Affected status and perception of the condition were correlated with the importance placed on knowing the prenatal diagnoses of achondroplasia and average stature. Views on abortion were highly correlated with all aspects of interest in prenatal diagnosis for achondroplasia. CONCLUSION: These results elucidate the role of selected attitudes and beliefs that contribute to reproductive decision making about achondroplasia. Furthermore, the findings provide insights into education and counseling issues for families and health care practitioners.

Genetic testing for cancer predisposition.

The onslaught of genetic innovations in the past decade has resulted in the ongoing identification of a spectrum of genes, some of which, when mutated, result in cancer susceptibility. The impact of these discoveries on healthcare provides an opportunity to enhance health promotion and long-term health outcomes by identifying at-risk individuals before cancer develops. This provides the healthcare provider with the potential to intervene much earlier to either reduce the risk or diagnose a cancer early when the chances for effective treatment are greatest. Even though genetic testing is increasingly being employed clinically, there remains a gap between the technology and effective interventions. Genetic tests also provide information that is distinct from other tests used routinely in health promotion, because of the personal and family nature of the information. This results in unique clinical, ethical, legal, and social issues that further affect the effective diffusion of this technology clinically. This article provides an overview of the distinguishing characteristics of genetic testing, outlines the essential components of informed consent, and discusses the potential implications of testing on individuals' lives and the nurse's role in offering genetic testing.

Future directions in genetic counseling: practical and ethical considerations.

The accelerated discovery of gene mutations that lead to increased risk of disease has led to the rapid development of predictive genetic tests. These tests improve the accuracy of assigning risk, but at a time when intervention or prevention strategies are largely unproved. In coming years, however, data will become increasingly available to guide treatment of genetic diseases. Eventually genetic testing will be performed for common diseases as well as for rare genetic conditions. This will challenge genetic counseling practice. The ethical principles that now guide this practice take into account the personal nature of test decision making, the need to respect individual self-determination, and the importance of client confidentiality. Certain of these principles may have to be modified as genetic testing becomes more widespread in order to meet the changing needs of clients and society. This paper offers recommendations to ensure that genetic counselors will take a leading role in the future delivery of ethical genetic services.

Unintended messages: the ethics of teaching genetic dilemmas.

Bioethicists teaching and writing about the uses of prenatal genetic testing sometimes use "difficult cases" in which people with a disability want to test and select for the presence of their disability. Such cases challenge our stereotypes but also play into them.
