Abstract: In this article we determined the course of psychological distress during a breast cancer surveillance program in women at increased risk of developing hereditary breast cancer (BC). The sample comprised of 357 unaffected women (mean age 40.5 years) adhering to a surveillance programme (MRISC-study). Before and after two successive biannual surveillance appointments, the Impact of Event Scale (BC-specific distress) and the Hospital Anxiety and Depression Scale (general distress) were administered, totalling four measurement moments. In general, psychological distress remained within normal limits and decreased significantly after a surveillance appointment, except for breast cancer specific distress after the second appointment. Scheduled imaging examinations were not significantly related to distress. The course of BC specific distress differed significantly for risk over-estimators and for young (<40 years) excessive breast self examiners. The course of general distress differed significantly for women closely involved in a sister’s BC-process. These more vulnerable subgroups may be in need of extra counselling and care.

The magnetic resonance imaging screening (MRISC) study evaluates a surveillance programme for women with a hereditary risk for breast cancer. The psychological burden of surveillance in these women may depend on inaccurate risk perceptions. To examine differences in risk perceptions between three predefined risk categories and associations with psychological distress. BC-specific distress, general distress, and RP (cognitive and affective) were assessed, two months before a surveillance appointment. Cumulative lifetime risk (CLTR) of developing breast cancer was trichotomised into: (1) CLTR of 60–85% (mutation carriers), (2) CLTR of 30–50%, and (3) CLTR of 15–30%. In a total group of 351 women (mean age 40.5 years, range 21–63 years) the three risk categories significantly differed in their accuracy of assessing cognitive risk perceptions. In category 1, 60% had an accurate risk perceptions, in category 2, 43.7% and in category 3, 33.3%. Overestimators reported significantly more breast cancer-specific distress. After adding affective risk perception to the model, this effect disappeared. Affective risk perceptions showed significant associations with breast cancer-specific and general distress. Affective risk perception is a more important determinant for psychological distress than cognitive risk perception. This knowledge should be used during surveillance appointments in order to improve and individualise support for these women. [Copyright &y& Elsevier]

Background: Counseling for whole-exome sequencing (WES) could benefit from aligning parents' pre- and post-disclosure attitudes. A few studies have qualitatively compared parents' pre- and post-disclosure attitudes toward receiving WES results for their child in a diagnostic setting. This study explored these attitudes in the context of children with a developmental delay., Methods: Semi-structured interviews were conducted with parents (n = 27) of 16 children undergoing diagnostic WES in trio-analysis, both before and after receiving results., Results: Three key insights emerged. First, the distinction between hoping and expecting was relevant for shaping parents' experiences with receiving results related to the primary indication. Second, parents of young children whose development of autonomous capacities was uncertain sometimes found themselves in a situation resembling a Catch-22 when confronted with decisions about unsolicited findings (UFs): an important reason for consenting to WES was to gain a better picture of how the child might develop, but in order to make responsible choices about UFs, some ideas of their child's development is needed. Third, default opt-ins and opt-outs helped parents fathom new kinds of considerations for accepting or declining UFs in different categories, thereby aiding decision-making., Conclusion: Results from this study are relevant for counseling and policy development., (© 2023 The Authors.

Pre-symptomatic frontotemporal dementia (FTD) mutation carriers and first-degree family members that are 50% at-risk for FTD may experience symptoms of anxiety and depression as a result of the ambiguity of when or if symptoms of the disease will manifest. We conducted a pilot study to investigate the use of an online mindfulness-based stress reduction (MBSR) course to reduce symptoms of anxiety and depression in presymptomatic frontotemporal dementia (FTD) mutation carriers and individuals 50% at-risk. Seven known mutation carriers and six individuals 50% at-risk completed a standardized 8-week MBSR course, and filled out pre- and post and two-month follow-up questionnaires. The primary outcome measure was the Hospital Anxiety and Depression Scale (HADS). Measures of psychological distress (SCL-90-R), coping style (UCL), quality of life (SF-36) and mindfulness skills (FFMQ) were administered as secondary outcome. Group effects were analyzed with repeated measures ANOVA or Friedman's test, and the individual reliability change index (RCI) was calculated per participant for each outcome measure. Semi-quantitative data included an evaluation and process measure post-intervention. Significant decline was found on the HADS-A post-intervention and after 2 months ( p = 0.01), with 54% and 62% of participants demonstrating a clinically significant RCI, respectively. On the HADS-D, significant decline was found 2 months post-intervention ( p = 0.04), which was driven by 23% of participants whom had a clinically significant RCI. Additional changes were found between baseline and post-intervention on the seeking distraction and reassuring thoughts subscales of the UCL, the depression and interpersonal sensitivity subscales of the SCL, the observe subscale of the FFMQ, and on physical role limitations of the SF-36 (all p < 0.05). The process evaluation form indicated that the course was found beneficial by participants, and that they applied it in a wide range of everyday situations. This exploratory pilot study indicates the feasibility of MBSR in reducing anxiety and depression in presymptomatic FTD mutation carriers and 50% at-risk individuals. A randomized controlled trial is necessary to replicate these results., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Poos, van den Berg, Papma, van der Tholen, Seelaar, Donker Kaat, Kievit, Tibben, van Swieten and Jiskoot.)

Prior research has found that many genetic counselors (GCs) experience burnout. Studies of other clinicians have demonstrated that burnout can have significant detrimental consequences for clinicians, patients, and the healthcare system. We sought to explore the prevalence of, contributors to, and consequences of burnout among GCs. We performed a secondary data analysis of baseline data from Me-GC, a randomized controlled trial of meditation for GCs. We applied a systems model of burnout proposed by the National Academy of Medicine (NAM), which depicts burnout arising from a combination of contributors that include both work system and individual mediating factors, and then leading to consequences. Validated self-report scales were used to measure burnout and most contributors and consequences. Female and white GCs were over-represented in our sample. Over half (57.2%) of the 397 participants had Professional Fulfillment Index scores indicative of burnout. Multiple potential contributors were associated with burnout, consistent with its known multifactorial nature. Among work system factors, higher levels of burnout were associated with insufficient administrative support, lack of autonomy, and not feeling valued by non-GC colleagues. Individual mediating factors associated with greater burnout included higher levels of anxiety, depression, and stress. Participants with lower levels of burnout reported greater mindfulness, resilience, and use of professional self-care behaviors. Among variables categorized as consequences, higher levels of burnout were associated with lower levels of empathy, counseling alliance, and positive unconditional regard, as well as higher reactive distress, and a greater desire to reduce the amount of time spent on clinical care. Given the prevalence and potential consequences of burnout observed here, it is imperative that the field take steps to mitigate burnout risk., (© 2021 The Authors.

Background: The goal of postmastectomy breast reconstruction (BR) is to improve the quality of life of patients. However, complications following autologous BR (A-BR) and implant-based BR (I-BR) occur frequently and may even lead to BR-failure, which can be a distressing event for both patients and surgeons. The current study, therefore, examines the experiences of both patients and surgeons after a BR-failure., Methods: Patients with a failed BR from a large multicenter cohort study and participating plastic surgeons were invited to participate in semi-structured interviews focusing on their experiences. The interviews were analyzed according to the principles of grounded theory., Results: Fourteen patients with a failed I-BR, four patients with a failed A-BR, and four plastic surgeons were participated. Three main categories emerged from the data: personal experiences with BR-failure, the motives for a redo of a failed BR, and patient-surgeon communication. Patients would like to be treated with more attention to their personal feelings and lives, instead of being approached from a purely medical-technical perspective. Surgeons may experience feelings of guilt leading to the strong urge to fix the failed BR, whereas patients may be less inclined to undergo additional operations. Patients want to know what the choice for a particular type of BR would mean to their personal lives. The impact of I-BR-failure may be underestimated and requires the same degree of intensive aftercare and attention., Conclusions: Implementing the recommendations of this study in clinical practice may facilitate improvements in how both patients and surgeons cope with a BR-failure., Competing Interests: Declaration of Competing Interest None., (Crown Copyright © 2020.

In a previous study we found that parents of children with developmental delay (DD) favoured acceptance of unsolicited findings (UFs) for medically actionable conditions in childhood, but that preferences diverged for UFs with no medical actionability, or only in adulthood, and regarding carrier status. Sometimes the child's future autonomy formed a reason for withholding UFs for the present, despite an unfavourable prognosis concerning the child's cognitive capabilities. This might be different for children undergoing whole exome sequencing (WES) for reasons other than DD and who are expected to exert future autonomy. This is the focus of the current study. We conducted nine qualitative, semi-structured interviews with parents of children, ages <1-15, after consenting to WES, but prior to feedback of results, and with three adolescent children. Several parents wished to receive any information that might in whatever way be relevant to the health and well-being of their child, and to a lesser extent wished the inclusion of information about non-actionable disorders and information concerning carrier status of autosomal recessive disorders. Although parents understood the rationale behind the centre's UFs disclosure policy, they also felt that they needed this information in order to be able to exert their parental responsibility and take good care of a child still dependent on them. Parents reason from their notion of parental responsibility but are also inclined to take adolescent children's preferences seriously and acknowledge the child's incipient autonomy as a ground for granting an increasing degree of self-determination on the road to adulthood.

The noninvasive prenatal test (NIPT) as the first trimester prenatal screening (FTS) for trisomies 21, 18, and 13 is offered to all pregnant women in the Netherlands. NIPT using genome sequencing allows for an expansion of the scope of FTS and the introduction of NIPT gives rise to ethical and societal concerns about deliberated decision-making, pressure to engage in screening, and possible lack of equal access due to the financial contribution (€175) to NIPT. We explored the opinions and experiences of pregnant women, who were offered FTS, about these concerns, and the possibility of a broadened scope. Nineteen pregnant women representing a diversity of backgrounds were interviewed using a semi-structured interview guide. Eight women did not opt for prenatal screening while 11 did (NIPT = 4, combined test = 7). Women experienced a free choice to accept or decline prenatal screening, despite sometimes receiving advice from others. Prior to pretest counseling, some women had already deliberated about what an abnormal test result would mean to them. Others accepted or declined FTS without deliberation. The current Dutch policy of requiring a co-payment was acceptable to some, who believed that it functioned as a threshold to think carefully about FTS. Others were concerned that a financial threshold would lead to unequal access to screening. Finally, pregnant women found it difficult to formulate opinions on the scope of FTS, because of lack of knowledge. Life expectancy, severity, and treatability were considered important criteria for the inclusion of a condition in NIPT., (© 2019 The Authors.

Testing options for pregnant women at increased risk of common aneuploidies are non-invasive prenatal testing (NIPT) and invasive prenatal diagnosis (PND). Clinicians are challenged to comprehensively discuss the complex information in a patient-centered and non-directive manner, to allow for patients' informed decision-making. This study explored the information-centeredness, patient-centeredness, and level of non-directivity of different clinicians and examined group differences between their patients. First, semi-structured interviews with four senior obstetricians and one senior nurse were held regarding their information provision, their adaptation of a patient-centered attitude, and their practice of non-directivity. Interviews were transcribed verbatim and rated by four independent researchers. Secondly, 181 pregnant women were included in the study, of whom 82% opted for NIPT and 18% chose PND. Between clinicians, we assessed the distribution of choice ratios, patients' impression of clinicians' test preferences, and patients' knowledge scores. The results indicate that clinicians do not differ in their information-centeredness, but do differ in their patient-centeredness and their level of non-directivity. Significant differences in patients' NIPT/PND ratios were observed between clinicians, with the largest difference being 35 vs. 4% opting for invasive PND. Between 9 and 22% of the patients had an impression of their clinician's preference and chose in accordance with this preference. Patients' overall knowledge scores did not differ across clinicians. In conclusion, the differences in NIPT/PND ratios between clinicians indicate that clinicians' differing counseling approaches affect the choices their patients make. The interviews indicate a possible framing effect which may unintentionally steer the decision-making process.

Amongst the main reasons people at risk for Huntington's disease (HD) have for undergoing predictive genetic testing are planning a family and prevention of passing on an expanded CAG-repeat to future offspring. After having received an unfavourable test result, a couple may consider prenatal testing in the foetus or preimplantation genetic diagnostic testing (PGD) in embryos. Testing of the foetus or embryos is possible by means of direct testing of the expanded repeat. Optimal reliability in testing the foetus or embryos requires the establishment of the origin of the repeats of both parents in the foetus. For PGD the analysis is combined with or sometimes solely based on identification of the at-risk haplotype in the embryo. This policy implies that in the context of direct testing, the healthy partner's CAG repeat lengths in the HD gene are also tested, but with the expectation that the repeat lengths of the partner are within the normal range, with the proviso that the partner's pedigree is free of clinically confirmed HD. However, recent studies have shown that the expanded repeat has been observed more often in the general population than previously estimated. Moreover, we have unexpectedly observed an expanded repeat in the non-HD partner in four cases which had far-reaching consequences. Hence, we propose that in the context of reproductive genetic counselling, prior to a planned pregnancy, and irrespective of the outcome of the predictive test in the HD-partner, the non-HD partner should also be given the option of being tested on the expanded allele. International recommendations for predictive testing for HD should be adjusted.

Follow-up studies on predictive testing for hereditary neurodegenerative diseases mainly focussed on psychological outcomes. We investigated whether the social and personal life of mutation carriers differ negatively from non-carriers and untested at-risk individuals. Asymptomatic individuals (≥ 35 years) who received a genetic test result for Huntington's disease, frontotemporal dementia or Alzheimer's disease more than 2 years before the onset of the study and untested subjects at 50% risk were invited to complete a questionnaire and an additional questionnaire with extra or adjusted items. Of the 283 selected individuals, 115 returned a positive informed consent (response rate 39.6%). Of these, 17 carriers, 30 non-carriers and 27 untested persons (n = 74) fulfilled the criteria and completed both questionnaires. We found no significant differences in employment, financial situation and lifestyle or anxiety and depression between carriers and non-carriers or untested individuals at risk. Carriers were more often single and childless, though these differences were not significant. The findings of this study suggest that the result of predictive testing on adult-onset neurodegenerative diseases does not have a large negative effect on social and personal life, although these observations should be interpreted with caution because of the small number of participants and low response rate.

Background/aims: Pediatric rare disease presents a challenging situation of high unmet need and a limited pool of potential clinical trial participants. Understanding perspectives of parents of children who have not participated in trials may facilitate approaches to optimize participation rates. The objective of this study was to explore factors associated with parental interest in enrolling children with pediatric neuromuscular disorders in clinical trials., Methods: Parents of individuals with Duchenne or Becker muscular dystrophy and spinal muscular atrophy were recruited through advocacy organizations, a registry, and clinics. These parents ( N = 203) completed a questionnaire including assessments of barriers and facilitators to clinical trial participation, parents' interest in trial participation, and their perceptions of others' views about participation in a clinical trial., Results: Trial interest in participating parents was high (64% combined group). The most highly endorsed barrier to participation was the possibility of receiving placebo, followed by not having enough information on risks and trial procedures. Compared to parents of children with Duchenne or Becker muscular dystrophy, parents of children with spinal muscular atrophy endorsed significantly more information and knowledge barriers. The greatest facilitators of participation were (1) confidence in improving disease understanding and (2) guarantee to receive the treatment after a successful trial. A logistic regression model, χ 2 (4, n = 188) = 80.64, p < .001, indicated that higher perceived barriers and more frequent trial communication by the provider were associated with lower interest, while positive trial perceptions by the child's providers and concordance in trial perceptions among those close to the decision-maker were associated with higher interest., Conclusion: We found high parental interest in pediatric neuromuscular trials that was tempered by concerns about the potential for randomization to a placebo arm. Participants perceived that their trial participation would be facilitated by additional education and guidance from their clinicians. Yet, intentions were negatively associated with frequency of provider communication, perhaps reflecting waning parental interest with a greater understanding of limitations in trial access, increased sophistication in their understanding of trial design, and appreciation of potential burden. To support parents' informed decisions, it is important to educate them to evaluate the quality of research, as well as providing lay information explaining the use of placebo, trial processes, and potential barriers to long-term drug access. Our findings should inform the development of targeted educational content, clinician training, and decision support tools.

Parents' preferences for unsolicited findings (UFs) from diagnostic whole-exome sequencing (WES) for their children remain largely unexplored. Our aim was to gain insight into parental considerations favoring acceptance/decline of UFs pertaining to their child. We conducted 20 qualitative, semistructured interviews with parents (n=34) of children with a developmental delay, aged <1 to 17 years, after consenting to WES, but before feedback of results. Key findings from our study were that all parents favored acceptance of UFs for medically actionable conditions in childhood, but that preferences and considerations diverged for UFs with no medical actionability, or only in adulthood, and regarding carrier-status. Sometimes non-medical utility considerations (considerations of usefulness of knowing UFs, not rooted in (preventive) medical treatment or controls) were given in favor of disclosure of UFs. Sometimes the child's future autonomy formed a reason to withhold UFs at present, despite an unfavorable prognosis concerning the child's cognitive capabilities. Some parents only preferred receiving UFs if these findings were directly related to their reasons for seeking a diagnosis. These findings are essential for developing morally responsible policy and for counseling. Further research should focus on whether considerations of non-medical utility alone can justify disclosure of UFs and whether reasons for seeking a diagnosis place further constraints on what UFs may be returned/withheld. How parents can be aided in contemplating different scenarios regarding their child's future development also deserves further inquiry.

Predictive genetic testing for a neurogenetic disorder evokes strong emotions, and may lead to distress. The aim of this study is to investigate whether attachment style and emotion regulation strategies are associated with distress in persons who present for predictive testing for a neurogenetic disorder, and whether these psychological traits predict distress after receiving test results. Self-report scales were used to assess attachment insecurity (anxiety and avoidance) and maladaptive emotion regulation strategies (self-blame, rumination, catastrophizing) in adults at 50 % risk for Huntington's Disease (HD), Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL), and Hereditary Cerebral Hemorrhage With Amyloidosis - Dutch type (HCHWA-D), when they presented for predictive testing. Distress was measured before testing and twice (within 2 months and between 6 and 8 months) after receiving test results. Pearson correlations and linear regression were used to analyze whether attachment style and emotion regulation strategies indicated distress. In 98 persons at risk for HD, CADASIL, or HCHWA-D, attachment anxiety and catastrophizing were associated with distress before predictive testing. Attachment anxiety predicted distress up to 2 months after testing. Clinicians may consider looking for signs of attachment anxiety and catastrophizing in persons who present for predictive testing, to see who may be vulnerable for distress during and after testing.

Objective: To investigate childhood experiences and psychological characteristics in offspring of a parent with genetic disease., Method: Self-report scales were used to assess adverse childhood experiences (ACEs), adult attachment style, mental health, and psychological symptomatology in offspring of a parent with a neurogenetic disorder (i.e. Huntington's Disease, HD; Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy, CADASIL; and Hereditary Cerebral Hemorrhage With Amyloidosis-Dutch type, HCHWA-D), and in offspring of a parent affected with Hereditary Breast/Ovarian Cancer (HBOC). These groups were compared to persons who did not have a parent with one of these genetic diseases. Associations between childhood experiences and adult psychological characteristics were investigated., Results: Compared with the reference group (n = 127), offspring of a parent with a neurogenetic disorder (n = 96) reported more parental dysfunction in childhood, and showed more adult attachment anxiety and poorer mental health. Offspring of a parent with HBOC (n = 70) reported more parental loss in childhood and showed poorer mental health. Offspring who experienced parental genetic disease in childhood had more attachment anxiety than offspring who experienced parental disease later in life. In the group of offspring, a higher number of ACEs was associated with poorer mental health and more psychological symptomatology., Conclusions: This cross-sectional study indicates that adult offspring of a parent with genetic disease may differ in attachment style and mental health from persons without one of these genetic diseases in their family, and that this may be related to adverse childhood experiences.

The aim of this study was to investigate the presence of thoughts or wishes for the end of life in patients with Huntington's disease (HD) or identified gene carriers (further mentioned together as patients). A custom-made questionnaire, based on previous qualitative research, was sent out to 242 patients with HD and identified gene carriers. Presence of wishes was investigated and correlated to demographic and clinical characteristics. A total of 134 patients (55 %) returned the questionnaire. 101 respondents (75 %) reported to have some kind of thoughts or wishes for the end of life. For 15 respondents (11 %) these thoughts concerned care; 86 respondents (64 %) reported to have also thoughts about euthanasia or physician-assisted suicide (PAS). The presence of any thoughts about the end of life was significantly related to being familiar with HD in the family, but not related to any other demographic or clinical variable. Participants with thoughts specifically about euthanasia or PAS were of higher education and in earlier stages of the disease than participants without such thoughts. Thoughts or wishes for the end of life are present amongst patients with HD. These thoughts include euthanasia or PAS in a majority of the respondents. It is suggested that prudential addressing of these issues may enhance the doctor-patient relationship.

Objective: Dystrophia myotonica is characterized by progressive muscular weakness, myotonia, mental slowness and lack of initiative, which causes problems in daily life both for patients and for their spouses. Some couples seem to deal with these problems satisfactorily, while for others they are quite burdensome. The aim of this study was to describe the relationship of severity of dystrophia myotonica and psychological wellbeing in patients and partners., Methods: Sixty-nine couples, in whom one partner had dystrophia myotonica, completed questionnaires on severity of dystrophia myotonica, marital satisfaction, anxiety and depression (Hospital Anxiety and Depression Scale), hopelessness (Beck Hopelessness Scale) and general psychological health (General Health Questionnaire-12)., Results: For patients, a worse view of the future, worse general wellbeing, more anxiety and more depression was associated with a greater need for help. For partners, worse general wellbeing and more anxiety was associated with a lack of initiative of the patient and less marital satisfaction. It is noteworthy that 40% of patients and particularly female partners had Beck Hopelessness Scale scores suggestive of clinically relevant depression., Conclusion: Dystrophia myotonica places a heavy burden on patients, and especially on female partners. The need for help and dependency has more influence on the wellbeing of patients than the symptoms of dystrophia myotonica themselves. Marital satisfaction is a strong predictor of better wellbeing, both for patients and, even more so, for partners.

The majority of individuals at risk for Huntington disease (HD) is afraid to learn more precisely about their genetic status, as is suggested by the low uptake of the predictive test for HD. Subsequently, the future expectancies of individuals at risk are often based on rough risk estimates such as 50% (child of an affected individual) or 25% (grandchild). Individuals at risk can be offered a better risk estimate based on their current age, length of the disease causing CAG-repeat in the HD gene in close relatives, information on the age at onset, or test results of children. Regression modelling and Cox regression determined relations between ages at onset and CAG repeat length in a sample of 755 tested individuals. A model for calculating the adjusted residual risk status was constructed and implemented in a spreadsheet that can be used in genetic counselling. This model and accompanying spreadsheet broadens the information repertoire for genetic counsellors by providing an optimal estimation of the residual risk status.

Purpose: DNA mutation testing for breast cancer usually yields an uninformative result, which is a negative result in the absence of a known BRCA mutation within the family. However, few data are available on the psychological impact of this result. Moreover, the clinical heterogeneity within this group has not yet been considered. This study provides prospective data about the course of cancer-specific worry and distress for different groups of test applicants., Patients and Methods: All DNA test applicants (n = 238) completed three questionnaires: before and 1 and 7 months after disclosure of a DNA mutation test. With repeated-measures analysis of variance, differences were assessed between BRCA1/2-positive women (n = 42), BRCA1/2-true-negative women (n = 43), and women with an uninformative test result (n = 153)., Results: On the group level, women with an uninformative result seemed to be reassured after disclosure (P < .001), but to a lesser extent than those women who received a true-negative result. However, not all women with an uninformative result reacted similarly: higher levels of worry and distress could be explained by relatively straightforward clinical variables, namely a personal history of cancer (P < or = .001) and a higher pedigree-based risk (P < or = .005). Furthermore, these clinical variables determined whether these women were either comparable to women who received a true-negative result or to BRCA mutation carriers., Conclusion: Women with an uninformative result form a heterogeneous group of test applicants. The subpopulation of those with both a personal history of cancer and a relatively high pedigree-based risk expressed the highest levels of worry 7 months after DNA testing.

Familial cancer services have been developed in many countries in response to a rapidly evolving demand for genetic counseling and testing for breast cancer risk. This article presents a synthesis of the literature on international aspects of genetic counseling and testing and discusses similarities and differences in the provision of genetic counseling and testing, taking seven countries with well established familial cancer services as a case study (Australia, Canada, France, Germany, Netherlands, UK and US). Potential international differences are discussed in terms of: provider and patient attitudes to genetic counseling and genetic testing; utilization rates of genetic testing and prophylactic surgery; and the psychological impact of genetic testing for breast cancer risk. The comparative analyses of utilization rates and the psychological impact of testing indicate a wide range of variability in uptake rates and psychological outcomes, most likely reflecting sample variability and methodological differences in measurement. International comparison studies using controlled designs would be required to ascertain whether international differences exist, and to disentangle the differential role of clinical, individual and family context factors, on the one hand, and the cultural and health system-related factors unique to particular countries, on the other.

Objectives: To assess whether healthcare professionals correctly incorporate the relevance of a favourable test outcome in a close relative when determining the level of risk for individuals at risk for Huntington's disease., Design and Setting: Survey of clinical geneticists and genetic counsellors from 12 centres of clinical genetics (United Kingdom, 6; The Netherlands, 4; Italy, 1; Australia, 1) in May-June 2002. Participants were asked to assess risk of specific individuals in 10 pedigrees, three of which required use of Bayes' theorem., Participants: 71 clinical geneticists and 41 other healthcare professionals involved in genetic counselling., Main Outcome Measures: Proportion of respondents correctly assessing risk in the three target pedigrees; proportion of respondents who were confident of their estimate., Results: 50%-64% of respondents (for the three targets separately) did not include the favourable test information and incorrectly estimated the risks as being about equal to the prior risks; 77%-91% of these respondents were "sure" or "completely sure" that their estimations were correct. Twenty of the 112 respondents correctly estimated the risks for all three target pedigrees., Conclusions: Clinical geneticists and genetic counsellors frequently use prior risks in situations where Bayes' theorem should be applied, leading to overestimations of the risk for an individual.

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.

When BRCA1/2 genetic susceptibility testing was introduced in the clinic in the mid-nineties, the "Huntington protocol" was used in the counselling of individuals applying for genetic testing. This protocol includes at least three sessions with a certain reflection period before blood sampling. Evidence on the psychological impact of BRCA1/2 genetic susceptibility testing has been accumulating in the last years. We will give a short overview of these psychological studies in order to reflect the need of using the extensive Huntington protocol in the counselling of individuals applying for BRCA1/2 genetic susceptibility testing. A shortened and more flexible BRCA1/2 counselling protocol is delineated, in which the attention is focused on the needs and strengths of the individual.

Purpose: To explore long-term psychosocial consequences of carrying a BRCA1/2 mutation and to identify possible risk factors for long-term psychological distress., Patients and Methods: Five years after genetic test disclosure, 65 female participants (23 carriers, 42 noncarriers) of our psychological follow-up study completed a questionnaire and 51 participants were interviewed. We assessed general and hereditary cancer-related distress, risk perception, openness to discuss the test result with relatives, body image and sexual functioning., Results: Carriers did not differ from noncarriers on several distress measures and both groups showed a significant increase in anxiety and depression from 1 to 5 years follow-up. Carriers having undergone prophylactic surgery (21 of 23 carriers) had a less favorable body image than noncarriers and 70% reported changes in the sexual relationship. A major psychological benefit of prophylactic surgery was a reduction in the fear of developing cancer. Predictors of long-term distress were hereditary cancer-related distress at blood sampling, having young children, and having lost a relative to breast/ovarian cancer. Long-term distress was also associated with less open communication about the test result within the family, changes in relationships with relatives, doubting about the validity of the test result, and higher risk perception., Conclusion: Our findings support the emerging consensus that genetic predisposition testing for BRCA1/2 does not pose major mental health risks, but our findings also show that the impact of prophylactic surgery on aspects such as body image and sexuality should not be underestimated, and that some women are at risk for high distress, and as a result, need more attentive care.

In 1993, the gene mutation for Huntington disease (HD) was identified and testing became possible with a reliability of >99%, without the need for co-operation of relatives. In 1997, a systematic information program offered the mutation retest to individuals who had earlier received a linkage test result for HD, which has a residual uncertainty of 1-9%. The characteristics of 129 individuals tested by linkage analysis for HD are reported on, as well as the reasons for their reassessment by mutation testing. Three groups were compared: (1) people who were retested between 1993 and 1997, before this study had started, (2) people who were retested after we provided information, and (3) persons who refrained from retesting. Nearly half of the linkage-tested individuals were retested, with the exception of noncarriers with a residual risk of 1 or 2%. Of them, less than one out of five were retested. Carriers with a hopeful view on the future (BHS) and a better sense of well-being (GHQ) were more likely to have the retest. Female carriers were also more likely to have the retest before we contacted them. Noncarriers who were retested were more anxious (HADS) than noncarriers who refrained from the retest. Retestees were younger at the time of testing. No risk reversals were revealed by this study., (Copyright 2003 Wiley-Liss, Inc.)
