Abstract
Lynch syndrome (LS) is an autosomal dominant condition that increases an individual's risk of a constellation of cancers. LS is defined when an individual has inherited pathogenic variants in the mismatch repair genes. Currently, most people with LS are undiagnosed. Early detection of LS is vital as those with LS can be enrolled in cancer reduction strategies through chemoprophylaxis, risk reducing surgery and cancer surveillance. However, these interventions are often invasive and require refinement. Furthermore, not all LS associated cancers are currently amenable to surveillance. Historically only those with a strong family history suggestive of LS were offered testing; this has proved far too restrictive. New criteria for testing have recently been introduced including the universal screening for LS in associated cancers. This has increased the number of people being diagnosed with LS but has also brought about unique challenges such as when to consent for germline testing and questions over how and who should carry out the consent. The results of germline testing for LS can be complicated and the diagnostic pathway is not always clear. Furthermore, by testing only those with cancer for LS we fail to identify these individuals before they develop potentially fatal pathology. This review will outline these challenges and explore solutions. Furthermore, we consider the potential future of LS care and the related treatments and interventions which are the current focus of research.

Abstract
The field of genetics and the process of testing for genetic disorders have advanced considerably over the past half century, ushering in significant improvements in certain areas of medical diagnosis and disease prediction. However, genetic discoveries are accompanied by many social, emotional, and psychological implications, and counseling psychologists may be uniquely equipped to help clients deal with these issues. The present overview is intended to raise awareness of the multidimensional issues inherent in situations where clients seek genetic testing to diagnose or predict various medical conditions. Initially, the author presents a framework to help counseling psychologists identify and organize information within a genetic-testing context, followed by suggestions for addressing the various psychological, social, and multicultural issues potentially affecting client decision making, mental health, and behavior. Finally, the author raises considerations for training, continuing education, and professional practice to foster continued discussion among counseling psychologists preparing for, or presently working in, research and applied settings involving clients with genetic concerns.

Abstract
Schizophrenia is associated with high mortality and morbidity. The etiology of schizophrenia remains unclear, studies implicate a multifactorial origin with genetic and environmental factors. The adenomatous polyposis coli (APC) gene has been associated with FAP (familial adenomatous polyposis), and studies have linked it to schizophrenia. However, there are few studies which examine the association between FAP and schizophrenia. Limited data exist regarding recommendations for genetic counseling of adolescents with comorbid psychiatric illness. A case of an adolescent with FAP who developed psychotic symptoms is presented. This case hopes to add to the literature about mental illness in those with FAP. A review of literature about the role of APC in schizophrenia as well as implications of genetic counseling on those who suffer with mental illness will be discussed.

Abstract
Huntington's disease (HD) is a neurodegenerative genetic condition for which a predictive genetic test by mutation analysis has been available since 1993. However, whilst revealing the future presence of the disease, testing may have an adverse psychological impact given that the disease is progressive, incurable and ultimately fatal. This review seeks to systematically explore the psychological impact of genetic testing for individuals undergoing pre-symptomatic mutation analysis. Three databases (Medline, PsycInfo and Scopus) were interrogated for studies utilising standardised measures to assess psychological impact following predictive genetic testing for HD. From 100 papers initially identified, eight articles were eligible for inclusion. Psychological impact of predictive genetic testing was not found to be associated with test result. No detrimental effect of predictive genetic testing on non-carriers was found, although the process was not found to be psychologically neutral. Fluctuation in levels of distress was found over time for carriers and non-carriers alike. Methodological weaknesses of published literature were identified, notably the needs of individuals not requesting genetic testing, as well as inadequate support for individuals registering elevated distress and declining post-test follow-up. Further assessment of these vulnerable individuals is warranted to establish the extent and type of future psychological support.

Abstract
INTRODUCTION Research is underway to develop an early medical test for Alzheimer's disease (AD). METHODS To evaluate potential demand for such a test, we conducted a cross-sectional telephone survey of 2,678 randomly selected adults across the United States and four European countries. RESULTS Most surveyed adults (67%) reported that they are "somewhat" or "very likely" to get an early medical test if one becomes available in the future. Interest was higher among those worried about developing AD, those with an immediate blood relative with AD, and those who have served as caregivers for AD patients. Older respondents and those living in Spain and Poland also exhibited greater interest in testing. Knowing AD is a fatal condition did not influence demand for testing, except among those with an immediate blood relative with the disease. CONCLUSIONS Potential demand for early medical testing for AD could be high. A predictive test could not only advance medical research, it could transform political and legal landscapes by creating a large constituency of asymptomatic, diagnosed adults.

Abstract
This study identified levels of distress, and predictors of levels of distress, in women undergoing assessment for genetic risk of breast/ovarian cancer based on their family history. It comprised a cohort study following 154 women who completed questionnaires at entry into a cancer genetic assessment programme and following risk provision. Independent significant associates of anxiety following risk provision were age, neuroticism, feeling hopeless about developing cancer, a perceived lack of control over developing cancer, lack of a social confidant, and a coping response involving acceptance/resignation. Depression was associated with age, neuroticism, feeling hopeless about developing cancer, lack of social confidant, and a coping response involving acceptance/resignation. To avoid high levels of psychological morbidity in future cohorts undergoing cancer genetic risk assessment, information should be given that emphasises that some degree of control over health outcomes through behaviour change or increased surveillance is possible.

Abstract
PURPOSE The aim of the current research was to characterize psychological adjustment among partners of women at high risk of developing breast/ovarian cancer and to explore the relationship between women's and partners' adjustment. METHODS A study of 95 unaffected at-risk women and 95 partners was carried out using mailed, self-administered questionnaires with validated measures of psychological outcome. RESULTS Elevated levels of distress were noted in up to 10% of partners. High monitoring coping style and greater perceived breast cancer risk for their wife were associated with higher distress levels for partners. However, communicating openly with their wife and the occurrence of a recent cancer-related event in the woman's family were related to lower distress for partners. Partners' cancer-specific distress was positively related to their wives' distress. CONCLUSION Among partners with elevated levels of distress, the ability to provide effective support to the at-risk women and participate appropriately in their decision making may be compromised. These partners are likely to benefit from targeted clinical interventions designed to reduce their distress levels. The findings emphasize the importance of considering partners of at-risk women in service provision and highlight the need for partners to obtain information and support specifically tailored to their needs.

Abstract
UNLABELLED Introduction. The development of a DNA based diagnostic test has allowed for the genetic screening of many hereditary diseases. In addition to the identification of the deleterious gene, this screening process has led to the recognition of developing illnesses at high risk. In recent years, a number of genes predisposing to an inherited cancer syndrome have been identified. AIM OF THE STUDY Our purpose in this study was to determine whether subjects at risk who test for inherited colorectal cancer, are likely to develop a higher level of psychological distress than the norm, taking into consideration the particular history of this familial disease. METHODS The demographic and psychosocial aspects of our population was described using: 1) the State Trait Anxiety Inventory (STAI), 2) the Center for Epidemiologic Studies Depression (CES-D), 3) a perceived risk for the gene carrier, 4) subjective perception of personal vulnerability and 5) the role of the medical status (affected or not), which places the subject in either predisposition or predictive testing. RESULTS Results show that our population had a higher predisposition for depressive disorders (chi2=9,3. p=0.002) and a significantly higher state of anxiety (chi2=9,3. p=0.002), prior to genetic counselling, compared with other populations. We found no evidence in the medical status, nor the perceived risk. However, the assessment of one's own personal vulnerability is related to psychological distress. DISCUSSION These results highlight the particular vulnerability of subjects undergoing genetic testing as well as showing the pertinence of proposing psychological help throughout the process of these new specific diagnoses.

Abstract
OBJECTIVE To study differences between individuals opting for genetic cancer susceptibility testing of a known familial BRCA1/2 and HNPCC related germline mutation. METHODS Coping, illness perceptions, experiences with cancer in relatives and family system characteristics were assessed in 271 applicants for genetic testing before test result disclosure. Hereditary cancer distress, worry and cancer risk perception were assessed before, 1 week after, and 6 months after disclosure. RESULTS Individuals from BRCA1/2 and HNPCC mutation families did not differ with regard to the number of experiences with cancer in relatives, grief symptoms, the course of cancer distress, worry and risk perception through time and most illness perceptions, coping responses and family characteristics. Individuals from BRCA1/2 families perceived hereditary cancer as more serious. They reported more frequently a passive coping style, cancer worry and a less open communication with their partner and children. CONCLUSION Besides subtle differences, psychological mechanisms may be mainly identical in individuals opting for BRCA1/2 and HNPCC susceptibility testing. PRACTICE IMPLICATIONS Based on our findings, using a similar counseling approach for individuals opting for BRCA1/2 or HNPCC genetic susceptibility testing is justified. In this approach, attention should be directed more to individual aspects than to the type of disorder.

Abstract
This prospective study investigates the influence of two coping styles (monitoring and blunting) and perceived control (health locus of control and mastery) on emotional distress in persons at risk of a hereditary cardiac disease. Emotional distress in people at risk for a hereditary cardiac disease does not differ from the normal population, neither before nor after disclosure of the DNA-or clinical test results. Less monitoring reflects less emotional distress before the results of the DNA-test or clinical investigations are known, while a stronger feeling of mastery reflects less emotional distress both before and after the results of the tests are known. These results indicate that the negative effect of monitoring is temporary. Mastery is a more powerful predictor than health locus of control in this situation.

Abstract
This exploratory study investigates the experience of partners of women at high risk of developing breast/ovarian cancer and reports on the partners' views concerning their relationship, communication, future planning, children and childbearing, involvement in decision-making regarding screening and prophylactic measures, and information and support needs. In-depth interviews were conducted with 15 partners. Of these, seven were partners of women who were BRCA1/2 mutation carriers, five were partners of women with unknown mutation status, and three were partners of women who were non-carriers. None of the women had a previous diagnosis of breast or ovarian cancer. Partners of carriers and women with unknown mutation status were found to be more distressed than partners of non-carriers, with partners of mutation carriers reporting the most difficulties. Factors associated with better adjustment and coping for partners included dealing with this situation as a team with their wife, greater involvement in decision-making, satisfaction with their supportive roles and being optimistic. Decision-making difficulties in relation to prophylactic measures, concerns about their children possibly being at increased cancer risk, as well as the need to receive information directly from health professionals and the wish to meet other partners were also discussed.

Abstract
As a sequel to an earlier paper (Sarangi et al., 2004. J Genet Couns, 13(2), 135-155) examining genetic counselors' initiation of reflective frames, in this paper we analyze the variable ways in which clients respond to such reflective frames in the clinical setting. Of the six types of reflective questions identified, we focus on two types, which recur throughout the counseling protocol: (i) questions about clients' decisions to have genetic testing and (ii) questions exploring the potential impact of a positive or negative test result. The analytic focus here is on the mismatches surrounding clients' apparent readiness to discuss coping with the onset of disease (risk of disease) when they have been asked to discuss coping with genetic test results (risk of knowing). Our theoretical discussion is centered around the notion of alignment as a framework for locating the convergence and divergence of counselors' and clients' agendas in interaction. Drawing on detailed transcripts of 24 Huntington's Disease counseling consultations in South Wales, we analyze 119 counselor-client question-response sequences using the methodology of discourse analysis. Preliminary coding of clients' responses led us to identify three recurrent themes: (a) gaining knowledge as a basis for future action; (b) needing to know as a subjective necessity; and (c) downplaying what can be known. In a further analysis of extended data extracts, we draw attention to how clients display varying degrees of engagement with regard to the testing process and outcomes along the temporal and social axes. At one extreme, clients may take up the opportunity to engage in self-reflection, and thus endorse the legitimacy of the reflective frame. At the other extreme, clients may implicitly or explicitly challenge the relevance of self-reflection, and hence the usefulness of this counselor-initiated routine. We suggest that clients' varied response behaviors result from the perceived need of some clients to display their 'readiness' for predictive testing-an overarching 'meta-question' posed by the very existence of the counseling protocol.

Abstract
OBJECTIVE This exploratory study serves to illustrate the psychological impact on an extended family in the process of genetic counselling and testing for a potentially life-threatening arrhythmia, the long-QT syndrome (LQTS). METHOD All members of the third generation and their partners (n=11) were interviewed, the mutation carriers with partners twice. In addition they completed measures for anxiety and depression three times in 18 months. RESULTS During the interviews these family members emphasised the damaged solidarity when the family is divided into carriers and noncarriers of a mutation in a LQTS predisposing gene. This demonstrates one way in which a family can react to the reality of being at risk of a potentially severe disease. Rewriting family history and mourning early death seem other ways to deal with this. The distress scores, especially of the women, were moderate to clinically high, not because of their own chance of having an arrhythmia but more due to their children's risk. CONCLUSION Mothers need educational even more than emotional support, because the lifestyle of their carrier children is in need of radical change. The setting of a combined outpatient cardiogenetic clinic with a medical and psychosocial staff meets such needs efficiently.

Abstract
Most UK genetics centres offering predictive testing for hereditary non-polyposis colorectal cancer (HNPCC) use an extended counselling protocol originally developed for Huntington's disease. Shortened counselling may be more appropriate in the context of treatable genetic conditions such as HNPCC. Twenty-six high-risk individuals were randomized to extended genetic counselling (two sessions of education and reflection held 1 month apart) or shortened genetic counselling (a single educational session) prior to HNPCC testing. Prospective questionnaires, interviews and transcripts of counselling sessions were analysed. Participants were unsure what to expect prior to genetic counselling and had already decided to undergo genetic testing. There was no evidence of psychological harm caused by shortened genetic counselling, with a high level of satisfaction with the counselling received in both groups. Reflective counselling occurred in both groups but was framed in terms of practical action and information. Participants expressed differing preferences for the level of information received. This exploratory study indicates that shortened genetic counselling may be an appropriate means of supporting decisions already made by individuals about HNPCC testing. However, participants would benefit from preparatory information to help them reflect on issues not previously considered, which can then be explored more fully as part of a tailored counselling approach.

Abstract
The objective of this study was to conduct a broad-based systematic review of social, ethical, and legal considerations associated with genetic cancer risk assessment technologies (CaRATs). This paper focuses on psychosocial and ethical issues. Search results were limited to papers published in English, French, or German from January, 1990, to May, 2003. A quality assessment tool was developed and applied to retrieved papers. Application of the quality assessment tool resulted in 77 of 247 qualitative and quantitative primary research papers being reviewed and synthesized. A broad range of issues were addressed and grouped into content areas. Despite a large literature addressing psychosocial and ethical issues associated with CaRATs, many existing studies are not adequate to inform decision-makers and stakeholders. Careful policy analysis, as in some of the economic analyses reviewed here, is important to bridge this gap.

Abstract
PURPOSE Being at hereditary risk of breast cancer (BC) may lead to elevated levels of distress because of the impact of the BC-process in relatives. OBJECTIVE Determine the association between psychological distress and BC in relatives. We studied: kind of kinship with the affected relative(s), degree of involvement with the relative's BC, time elapsed since the BC diagnosis of the relative, and loss of a relative as a consequence of BC. METHODS The study cohort consisted of women at increased risk of developing BC, adhering to regular surveillance and participating in the Dutch MRISC-study. Two months prior to the surveillance appointment, demographics, general and BC specific distress and experience with BC in the family were assessed. RESULTS 347 out of 351 participants (mean age 40 1/2) had at least one relative affected with BC. The following variables were significantly, positively related to BC specific distress: having at least one affected sister (n = 105; p < 0.04); close involvement in a sister's BC process (n = 94; p < 0.03); and a recent (less than three years ago) BC diagnosis in a sister (n = 30; p < 0.03). General distress did not show any significant associations with the experience of BC in the family. CONCLUSION These findings show the impact of a BC diagnosis in a sister, particularly a recent diagnosis, on psychological distress. Women who have experienced BC in their sister may be in need of additional counselling or of more attention during the surveillance process.

Abstract
OBJECTIVES To assess the psychological effect of predictive testing in parents of children at risk for long QT syndrome (LQTS) in a prospective study. METHODS After their child was clinically screened by electrocardiography and blood was taken for DNA analysis, and shortly after delivery of the DNA test result, 36 parents completed measures of psychological distress. RESULTS 24 parents were informed that at least one of their children is a mutation carrier. Up to 50% of the parents of carrier children showed clinically relevant high levels of distress. Parents who were familiar with the disease for a longer time, who had more experiences with the disease in their family and who received positive test results for all their children were most distressed. CONCLUSIONS Predictive ECG testing together with DNA testing has a profound impact on parents whose minors undergo predictive testing for LQTS.

Abstract
In the last two decades predictive testing programs have become available for various hereditary diseases, often accompanied by follow-up studies on the psychological effects of test outcomes. The aim of this systematic literature review is to describe and evaluate the statistical methods that were used in these follow-up studies. A literature search revealed 40 longitudinal quantitative studies that met the selection criteria for the review. Fifteen studies (38%) applied adequate statistical methods. The majority, 25 studies, applied less suitable statistical techniques. Nine studies (23%) did not report on dropout rate, and 18 studies provided no characteristics of the dropouts. Thirteen out of 22 studies that should have provided data on missing values, actually reported on the missing values. It is concluded that many studies could have yielded more and better results if more appropriate methodology had been used.

Abstract
A qualitative study, based on family systems theory, was undertaken in order to gain a better understanding of the impact of predictive testing and of living with the risk or reality of Huntington disease (HD), on couple relationships. Semi-structured interviews were conducted with 14 couples; in 9 couples the at-risk partner had undergone testing, and of these, 4 were already affected with HD. At-risk partners in the remaining five couples had not been tested. Interview transcripts were analyzed to obtain a range of themes, which reflect the salient experiences of these couples in relation to HD. Most couples reported that receiving a predictive test result had little or no adverse effect on their relationship. However for two couples who separated after the at-risk partner received a non-carrier result, emotional factors associated with years of living with the HD risk, rather than the result itself, were regarded as having caused irreparable damage to the relationship. For two couples who have remained together since the diagnosis of one partner, loyalty was identified as the main factor contributing to the continuance of the relationship. The separations of the other two couples in which one partner was diagnosed were attributed to emotional distancing, and to the obsessive behavior of the affected partner. The findings of this study highlight both the individuality and the complexity of psychological effects on the intimate relationships of couples who live with the risk or reality of HD, and provide important insights for professionals offering support to these couples.

Abstract
The aim of the study was to evaluate the impact of a decision aid (DA) and its timing in women being tested for a BRCA1/2 mutation. Women with and without a previous history of cancer were included after blood sampling for genetic testing. The DA consisted of a brochure and video providing information on screening and prophylactic surgery. To evaluate the impact of the DA, women were randomised to the DA group (n=184), receiving the DA 2 weeks after blood sampling, or to the control group (n=184). To evaluate the impact of timing, mutation carriers who had received the DA before the test result (n=47) were compared to mutation carriers who received the DA after the test result (n=42). Data were collected on well-being, treatment choice, decision and information related outcomes. The impact of the DA was measured 4 weeks after blood sampling. The impact of timing was measured 2 weeks after a positive test result. The DA had no impact on well-being. Regarding decision related outcomes, the DA group more frequently considered prophylactic surgery (P=0.02) corroborated with higher valuations (P=0.04). No differences were found for the other decision related outcomes. Regarding information related outcomes, the DA group felt better informed (P=0.00), was more satisfied with the information (P=0.00), and showed more accurate risk perceptions. Timing of the DA had no effect on any of the outcomes. No interactions were found between the DA and history of cancer. In conclusion, women being tested for a BRCA1/2 mutation benefit from the DA on information related outcomes. Because timing had no effect, the DA is considered useful either before or after the test result.

Abstract
The identification of the BRCA1/2 genes, and their possible etiologic relationship with various forms of inherited cancer, has been recognized universally as a cornerstone in the search for cancer's genetic link and has made it possible to identify specific individuals and families who harbor a mutation in one of these predisposition genes. Genetic testing for breast and ovarian cancer susceptibility may pose unanticipated psychological and social problems. Because of the recent availability of predisposition genetic testing, research efforts have begun to investigate factors that may influence an individual's intention to undergo testing and the psychosocial sequelae associated with testing. The purpose of this article is to provide an integrative review of the literature that will delineate what is currently known about the psychosocial issues associated with genetic testing for breast and ovarian cancer risk. Important generalizations from the literature include: (a) a positive test for breast cancer susceptibility may ignite a psychological response similar to the diagnosis of breast cancer itself; (b) there is likely a subset of individuals at increased risk for hereditary breast and ovarian cancer who are also at risk for sustained psychosocial problems; (c) available literature challenges a common notion that only individuals with a positive test result will need psychosocial services; and (d) at-risk individuals are basing health care decisions on genetic testing information, thus they are making important decisions under conditions of uncertainty. Clinical issues and directions for future research were highlighted.

Abstract
OBJECTIVE Approximately 5-10% of prostate cancer cases are caused by dominantly inherited susceptibility to the disease. Although advances have been made in research concerning the genetic mechanisms of hereditary prostate cancer, little is known about the psychological consequences. The aim of this study was to assess possible negative psychological effects of screening for prostate cancer in a high-risk population. MATERIAL AND METHODS This study was based on a previous study of risk perception, screening practice and interest in genetic testing among unaffected men in families with hereditary prostate cancer. The present study included 87 men from the previous study who were screened regularly for prostate cancer. Of these, 74 men agreed to receive two further questionnaires, both of which included the Hospital Anxiety and Depression Scale (HAD) and the Impact of Event Scale (IES), one of which was filled in on the day of the next screening visit and the other 4-6 weeks later. RESULTS The response rate was 77% (57/74). There were no statistically significant differences in total or subscale HAD or IES scores between the two points of measurement. There was a trend towards slightly higher HAD scores on the day of the screening visit, but the difference was so small that we did not consider it clinically relevant. In an attempt to identify risk factors for a negative impact of screening several subgroup analyses were performed, but none of these subgroups had significantly higher scores on the day of the visit than afterwards. CONCLUSION Most men with a high hereditary risk of developing prostate cancer do not experience severe psychological adverse effects resulting from attendance for screening.

Abstract
The purpose of this study was to determine the current psychosocial functioning of women who had previously had a bilateral prophylactic mastectomy. Women in the province of Ontario who had undergone prophylactic mastectomy between 1991 and 2000 were asked to complete questionnaires that assessed psychological distress, sexual activity, overall satisfaction with decision to have a prophylactic mastectomy, and body image. Ninety-seven percent of the women were satisfied with their decision to have a prophylactic mastectomy, but young women (<50 years) were less likely to report satisfaction than older women (p=0.001). Women with a strong family history of breast cancer or a BRCA1 or BRCA2 mutation experienced more cancer-related distress than those with a limited family history. Women who had reconstruction following mastectomy reported higher levels of satisfaction with general body shape and appearance than those without reconstruction. In conclusion, the majority of women were satisfied with their decision to undergo prophylactic mastectomy and were not experiencing abnormal levels of psychological distress, low levels of sexual activity, or difficulties with body image.

Abstract
Although tailored print materials (TPMs) have been assessed for a variety of behavioral targets, their effectiveness as decision aids for genetic testing had not been evaluated at the time this study began. We compared TPMs and non-tailored print material (NPMs) that included similar content about genetic testing for breast and ovarian cancer susceptibility. TPMs were prepared especially for an individual based on information from and about her. We mailed baseline surveys to 461 women referred by physicians or identified through a tumor registry. All had personal and family histories of breast and/or ovarian cancer and, on the basis of these histories, an estimated > or =10% probability of carrying a mutation in the breast/ovarian cancer genes BRCA1 or BRCA2. The 325 (70%) who responded were randomly assigned to receive TPM or NPM. Followup surveys, mailed 2 weeks following receipt of print materials, were returned by 262 women (81% of baseline responders). Participants were predominately white (94%) and well-educated (50% college graduates). The mean age was 49 years. At follow-up, TPM recipients exhibited significantly greater improvement in percent of correct responses for the 13-item true/false measure of knowledge (24% increase for TPM vs. 16% for NPM; p < 0.0001) and significantly less over-estimation of risk of being a mutation carrier (40% TPM group overestimated vs. 70% NPM; p < 0.0001). Anxiety did not differ significantly between groups. Reactions to materials differed on two items: "seemed to be prepared just for me" (76% TPM vs. 52% NPM; p < 0.001) and "told me what I wanted to know about BRCA1 and 2 testing" (98% TPM vs. 91% NPM; p < 0.05). TPMs showed an advantage in increasing knowledge and enhancing accuracy of perceived risk. Both are critical components of informed decision making.

Abstract
Predictive testing for hereditary non-polyposis colorectal cancer (HNPCC) is typically offered within an extended genetic counselling protocol, originally developed in the context of Huntington's Disease. We conducted a questionnaire survey of 20 UK regional genetics centres to obtain evidence regarding current approaches to HNPCC pre-test counselling. Centres were asked to describe the structure and content of pre-test counselling and their views on shortening the protocol. Sixteen centres responded to the survey. Four centres were considering shortening the protocol or had already done so. The remaining centres followed an extended protocol of two sessions separated by a 1-month period for reflection, although two centres conceded that the protocol had been reduced in certain cases. Different centres used different terminology to describe the content of pre-test counselling. Although content areas relating to education or impact of test results were covered more frequently than those relating to reflection, there was a marked tendency to consider all three areas as essential and to use both educational and reflective counselling, even in those centres that favoured a shortened protocol. This apparent dilemma highlights both the practical difficulty of how to shorten HNPCC pre-test counselling protocols and the need for controlled trials of different approaches.

Abstract
PURPOSE Many women who have had breast or ovarian cancer who are undergoing tests for the presence of germline mutations in the genes will receive a result that is inconclusive. As this continuing uncertainty may have a detrimental effect on their psychological well-being and it is possible that such results will be misinterpreted as indicating that no mutation is present, studying their effect is important. METHODS Sixty-one women undergoing such tests completed questionnaires 2 weeks after their blood was taken and at 1 week and 6 months after receiving a preliminary "inconclusive" result, i.e., indicating that two thirds of the gene had been tested and no mutation had been found so far. RESULTS Perceived likelihood of having a mutation and perceptions of cancer risk significantly decreased after receipt of the interim result. There were no changes in levels of psychological distress and worry about cancer, in intentions to have mammograms, to carry out breast self-examination, or to have prophylactic surgery. CONCLUSIONS The continuing uncertainty does not seem to have increased distress; however, it is possible that the inconclusive result is being interpreted as a "good news" result, in view of the fact that perceptions of risk decrease after receipt of the result.

Abstract
Genetic testing enables women at risk for hereditary breast and/or ovarian cancer to find out whether they have inherited the gene mutation (BRCA1/BRCA2), and if so, to opt for frequent surveillance and/or prophylactic surgery (bilateral mastectomy and/or oophorectomy). Here, a follow-up is described for 63 healthy women at 50% risk of being a BRCA1/BRCA2 mutation carrier who underwent genetic testing. The course of distress and problems regarding body image and sexuality up to 1 year after disclosure of the test-outcome were described separately for mutation carriers undergoing mastectomy (n = 14), for mutation carriers opting for surveillance (n = 12) and for non-mutation carriers (n = 37). Furthermore, we analyzed whether women opting for prophylactic mastectomy differed from those opting for close surveillance with respect to biographical characteristics, experiences with cancer in relatives and personality. Women opting for prophylactic mastectomy had significantly higher distress levels than mutation carriers who opted for surveillance, and the non-mutation carriers. This difference in levels of distress was highest at pre- and post-test and had almost disappeared at 1-year follow-up. Besides, mutation carriers opting for prophylactic mastectomy were more often in their thirties, more often had young children and had a longer awareness of the genetic nature of cancer in the family than those opting for regular surveillance. Adverse effects were observed in women who underwent prophylactic mastectomy (mostly in combination with immediate breast reconstruction) regarding the perception of how their breast region looked like and felt, the intimate relationship and physical wellbeing whereas women opting for prophylactic mastectomy reported more distress than the other women in the study, their distress levels had significantly decreased 6 months or longer after surgery, possibly due to the significant risk reduction of developing breast cancer. This might explain, why most women who underwent prophylactic mastectomy were satisfied with this decision, despite a perceived negative impact on body image, the intimate relationship and physical wellbeing.

Abstract
This study sought to examine changes in psychological distress following cancer genetic counselling. Women attending a family cancer clinic completed questionnaires before their appointment and at 2 weeks, 6 months and 12 months after their appointment. Twenty-six women were at low risk of developing breast or ovarian cancer, 76 were at moderate risk, 46 were at high risk and 46 women had previously had breast or ovarian cancer. All groups were compared with regard to measures of anxiety, depression, general psychological distress, worry about developing breast and ovarian cancer, and perceived risk of developing breast/ovarian cancer and perceived likelihood of carrying a genetic mutation. General psychological distress did not change over the course of the study and the groups did not differ on these measures. Worry about developing breast cancer and perceptions of the likelihood of carrying a genetic mutation significantly reduced following genetic counselling. On the whole women who had already had breast/ovarian cancer showed more concerns about ovarian cancer and raised perceptions of risk in comparison with the other groups, indicating the need for sensitive counselling of such women.

Abstract
The implications of predictive DNA-testing for Huntington's Disease (HD) for the transitions in the family life cycle are described. HD is a hereditary disorder leading to personality changes, uncontrollable movements, cognitive impairment, and ultimately death in mostly adults. People at risk have the possibility to detect whether or not they carry the disease provoking-gene, but no treatment is available. In this article, we will highlight the complex implications of pre-symptomatic testing by describing six different cases, interpreted by following the theoretical framework of Carter and McGoldrick (see pp. 684). HD interferes strongly with the "normal" transitions in the life cycle. It is not so much the test result itself that may be disrupting, but the changed expectations and possibilities for the future. As a family disease, HD forces its members to cope, one way or another, with disturbing events and untimely deaths. Some families are able to make some transitions, while becoming blocked at other transition points; this may differ between families. Being able to cope with HD in the family for a certain time does not necessarily imply that problems will never occur. Because any family member may eventually need help, it is important to then help the family discover what hinders them from making the transition to the next life stage, and to resolve these issues so that they can move on.

Abstract
The specific mutation on the tau gene responsible for a neurodegenerative disease known as pallido-ponto-nigral degeneration (PPND) was recently located. PPND family members are at risk for an autosomal dominant form of frontotemporal dementia with Parkinsonism linked to chromosome 17 (FTDP-17). This study investigated whether individuals in this family would consider presymptomatic genetic testing. Surveys were sent to 66 at-risk individuals in the family; replies were received from 20 (30%). Family members were asked if they would consider having testing now or in the future, and to indicate their reasons for and against proceeding with testing. Fifty per cent (n=10) of those who were at risk and who responded indicated they would consider testing now, and 55% (n=11) would think about it in the future. The most frequently cited reasons to proceed with testing were to 'collaborate with research' (70%) and to 'know if my children are at risk' (45%). The most frequently cited reason not to pursue testing was 'I can enjoy my life more fully by not knowing' (50%). Results suggest that interest in determining whether they will manifest PPND is generally low among at-risk members of this family, despite wide support and participation in other research studies.

Abstract
Between 1994 and 1998, the 23 UK genetics departments, which form the UK Huntington's Disease Consortium, have undertaken 161 direct mutation adult predictive tests on individuals whose at-risk parent was alive or had died without showing signs of Huntington's disease (HD) (5.7% of total UK tests). This study describes the number of requests for 25% risk predictive testing for HD in 1994 (the first year in which direct testing was available in the UK), and also a descriptive survey of the first 85 tests. In total, 85 tests were performed in the first 2 years of direct mutation testing, ten (11.8%) tests were mutation positive, 73 (85.91%) were negative and two (2.3%) were equivocal. The at-risk parent was alive in 54 (63.5%) cases. Four of the ten mutation positive candidates had parents who were alive and therefore received a prediction through their child. All centres included a discussion about the effect of testing on the 50% at-risk parent and all offered to see the parent for counselling. Of the 87 applicants for testing during 1994, 31 (35.6%) withdrew, this is higher than the 25% withdrawal rate for the 50% risk candidates. The candidates who withdrew were significantly younger and had more parents who were alive than those who continued with testing. Seven of the 31 candidates who withdrew from testing had at-risk parents who decided to be tested in the first instance. During the counselling process, issues were raised relating to pre-test agreements and family secrecy. This study indicates the importance of pre-test counselling and the involvement of the parent in the counselling process. 25% risk testing for HD is now being offered in the majority of UK centres. As more genes are identified for late-onset conditions, it is important that the complexities of 25% risk testing for late-onset conditions are not underestimated. This limited survey does not investigate how individual families cope with the psychological and social issues raised by this study and further research in this area is needed.

Abstract
Although a support person is required by many centers during the predictive testing protocol for Huntington disease (HD), little is known about the psychosocial impact of predictive testing on persons serving in this role. Eighteen adults who were support persons during predictive HD testing in one HD testing center completed a semi-structured interview to describe their experiences. Participants also completed the Impact of Events Scale (IES) to assess perceptions of emotional distress regarding predictive testing and the State Anxiety Scale of the State Trait Anxiety Inventory (STAI) to assess anxiety regarding the interview. State anxiety scores were similar to normative values for working adults. Although support persons for individuals with a positive gene test scored higher on all measures of the IES than those who were support persons for persons with negative gene mutation results, these differences were not statistically significant. Support persons identified aspects of the protocol that did not fit their needs, perceived the testing process as extending into subsequent caregiving responsibilities when the test was positive, and were uninformed regarding specific caregiving issues for family members with the gene mutation. The impact of the testing experience appeared to be most intense for those support persons who were at-risk offspring of probands. Findings suggest that individual assessment of support person needs may allow more focused counseling of support persons during predictive genetic HD testing. Collaboration with health care providers may facilitate symptom management following testing.

Abstract
Multiple endocrine neoplasia type 2 (MEN 2) is an autosomal dominant early-onset cancer disorder. In the Netherlands presymptomatic genetic testing for MEN 2 is offered to testees from the age of five years. We report on adults requesting testing for themselves (n=90) and on parents who want an at-risk child to be tested (n=26). Sociodemographic, personality, and attitude characteristics, and levels of psychological distress, were determined for applicants and their partners in the predisclosure phase of testing. These participants showed only mildly increased levels of psychological distress, defined as heightened scores on measures of general and test-related anxiety, and of psychological complaints. Compared with a normal population, high levels of anxiety and health complaints were found in applicants who were younger than 25 years and single, and in persons who generally tended to react to distressful situations with anxiety or depression. These characteristics were particularly evident in young applicants (<25 years). Our study shows that people who feel ambivalent towards DNA testing and who are more vulnerable to psychological distress are more likely to agree to participate in the test as part of a collective application by members of a hereditary cancer family.

Abstract
Along with the detection of several genetic mutations that are associated with increased susceptibility for hereditary cancer syndromes, e. g. hereditary breast/ovarian and colorectal cancer, genetic tests are available for members of families at risk. Until now, the benefit in terms of prevention still needs to be confirmed. Furthermore, a variety of legal, ethical and psychosocial risks has to be considered, unless predictive genetic testing results in additional härm for individuals and families. Guidelines including Standards for genetic analyses and comprehensive counseling have been established worldwide aiming at the prevention of negative consequences for persons at risk. The knowledge collected in Psychooncology is applicable to the field of genetic counseling. During the pre-test-phase counseling aims at supporting the process of decision-making, both in individuals and in families. After disclosure of test results psychosocial support aims to enhance adjustment and communication within families. A small subgroup at risk for increased psychosocial distress warrants additional support. Efforts in research are needed to evaluate psychosocial issues during the process of decision-making and outcome, with adequate length of follow-up. Risk factors indicating poor psychosocial outcome need to be identified in order to develop appropriate ways of support.

Abstract
OBJECTIVES To evaluate the feasibility of a reduced counselling programme for predictive genetic testing for hereditary non-polyposis colorectal cancer (HNPCC) in terms of counsellees' opinions on the extent and significance of genetic counselling and need for psychological support at different phases of the testing procedure. DESIGN Prospective follow up study with pre-test questionnaire assessment of background sociodemographic variables. The protocol comprised a pre-test counselling session, a period for reflection, and a test disclosure session. The outcome variables were studied by post-test questionnaires at one month and one year follow up. SUBJECTS Two hundred and seventy one high risk members of 36 families with HNPCC who attended both counselling sessions and completed the questionnaires. RESULTS The pre-test counselling was considered fairly or very useful by 89% of respondents and one post-test session was considered sufficient by over 80% of respondents at follow up. Fifty three percent would have used extra psychological support had it been offered with the counselling. On enquiry one year after receiving the test result, only 2% stated that the need for support was at its greatest at that time, while the majority (46%) reported that the need for support had been greatest at the moment of test disclosure. CONCLUSIONS A protocol that includes one comprehensive pre-test counselling session and a test disclosure session, supplemented with the option of professional psychological support, seems to be sufficient for both the educational and supportive needs of counsellees. Only a minority expressed a need for post-test follow up sessions, which suggests that, in this disorder, resources can be directed to the beneficial surveillance programmes rather than to extensive psychological support.

Abstract
BACKGROUND Psychometric testing of participants in predictive DNA testing for Huntington's disease (HD) has shown that 15% of the subjects at risk for HD had at least mild depression or a high score for general anxiety or both in the pre-test period. The main aim of the study was the delineation of variables associated with pre-test distress of applicants for predictive testing for HD. Based on theoretical considerations, four specific hypotheses were tested regarding the role of (1) the test participant's age at the (perceived) parental onset of HD, (2) the affected parent's sex, (3) the perception of the risk for HD, and (4) the subjective proximity of the disease. Secondly, these four variables were used in multiple regression analyses to select the best predictors of pre- and post-test psychological functioning (one year after the test). Increasing the understanding of pre- and post-test distress is important for developing better counselling and support strategies for test applicants. METHODS Data were collected by means of clinical interviews and psychometric questionnaires during the pre- and post-test (one year after the test) counselling sessions for predictive testing for HD. RESULTS We found significant associations of the participant's age at the parental onset, the subjective proximity of the disease onset, and the perceived risk with pre-test psychometric measures of psychological functioning. Multiple regression analyses showed that the best predictors of pre-test functioning were the perceived proximity of the disease onset and its interaction with risk perception. Regarding post-test functioning, none of the proposed variables had a unique contribution beyond that accounted for by pre-test psychological functioning. CONCLUSIONS Test participants who are close to the perceived age of onset of HD and who have a pessimistic risk perception should be given special attention during pre-test counselling because of their possible negative affective condition at that time. Pre-test psychological measures were the best predictors of post-test distress, irrespective of the test result. Suggestions for future longitudinal research are formulated. This kind of research should enable clinical geneticists and mental health professionals to refine the pre- and post-test counselling strategies for predictive DNA testing, not only for HD, but also for other incurable late onset disorders.

Abstract
Presymptomatic DNA testing for autosomal dominant hereditary breast/ovarian cancer (HBOC) became an option after the identification of the BRCA1 and BRCA2 genes in 1994-1995. Healthy female mutation carriers have a high lifetime risk for breast cancer (56-87%) or ovarian cancer (10-60%) and may opt for intensive breast and ovary surveillance or prophylactic surgery (mastectomy/oophorectomy). We studied general and cancer related distress in 85 healthy women with a 25% or 50% risk of being carrier of a BRCA1/BRCA2 gene mutation and 66 partners in the six to eight week period between genetic counselling/blood sampling and disclosure of the test result. Questionnaire and interview data are analysed. Associations are explored between levels of distress and (1) expected consequences of being identified as a mutation carrier, (2) personality traits, (3) sociodemographic variables, and (4) experiences related to HBOC. Mean pre-test anxiety and depression levels in women at risk of being a carrier and partners were similar to those of a normal Dutch population. In about 25% of those at risk of being a carrier and 10% of the partners, increased to high levels of general and cancer related distress were found. Increased levels of distress were reported by women who (1) anticipated an increase in problems after an unfavourable test outcome, (2) considered prophylactic mastectomy if found to be mutation carrier, (3) had an unoptimistic personality, (4) tended to suppress their emotions, (5) were younger than 40 years, and (6) were more familiar with the serious consequences of HBOC. Recently obtained awareness of the genetic nature of cancer in the family was not predictive of distress.The majority of the women and their partners experienced a relatively calm period before the disclosure of the test result and seemed to postpone distressing thoughts until the week of disclosure of the result. The low distress levels may partly be explained by the use of strategies to minimise the emotional impact of a possibly unfavourable test outcome. However, a minority reported feeling very distressed. Several factors were found to be predictive for increased distress levels.
