RESUMEN

Males with a BRCA1/BRCA2 mutation are not at greatly increased risk for cancer, whereas their (grand)daughters, and other female relatives who carry the mutation, are. Males from BRCA1/BRCA2 families may opt for genetic testing to confirm whether or not they may have transmitted the mutation to their children and, if so, to inform them at an appropriate age about the genetic risk and its implications. The psychological implications of genetic testing for men at risk of being a BRCA1/BRCA2 mutation carrier have received little attention. We report on 28 men requesting BRCA1 or BRCA2 testing, and their partners. Men were at 25% (n =4) or 50% risk (n =24) of being a mutation carrier, the majority with daughters and half of them with daughters aged over 20 years. Levels of psychological distress were assessed several weeks before and after disclosure of the test result. In addition, we investigated the level of intrusive thoughts and feelings about breast and ovarian cancer and the tendency to avoid these. By means of interviews and questionnaires, participants could report on (expected) emotional implications of genetic testing for themselves and their children, on experiences with cancer in the family and on personality trait optimism. Distress levels prior to the result in tested men and their partners were low. Many men and partners expected the test result to affect their children's, but not their own level of problems. Men without daughters and those with an optimistic personality had especially low distress prior to disclosure. Most men reported that they did not actively avoid the issue. Only four of the 28 men were identified as mutation carriers. High distress after disclosure of the result was reported by one mutation carrier and by three non-mutation carriers. Verbatim transcripts from interviews showed a large variation of psychological reactions in male mutation carriers (eg regarding guilt feelings). Low pre-test distress in males does not necessarily indicate avoidance of the issue. Future studies may indicate which psychological reactions occur in male mutation carriers when the problem becomes more acute, eg when a daughter is found to carry the mutation and/or is diagnosed with breast or ovarian cancer.

RESUMEN

An in-depth, recorded interview of 30 couples 2-3 years after genetic counseling explored the characteristics of the postcounseling decision-making process, including the role of guilt feelings towards the proband. The study concerned couples with an affected child, sib, or spouse. Results were evaluated by 2 to 4 judges. In contrast to other studies, a generally unstructured decision-making process was found whereby guilt feelings played a significant role in more than half the couples. Guilt feelings were more predominant in couples with an affected sib than in those with an affected spouse. Lack of structure did not seem to complicate the decision-making process. Therefore, authors do not advocate promotion of structuring the decision-making process. Genetic counselors might focus on understanding counselees' feelings concerning the reproductive decision. Acceptance of apparently irrational considerations is particularly important, because these feelings indicate the influence of unconscious motives. Another important aspect of supporting counselees is to understand the role played by guilt feelings toward parents or an affected sib.

RESUMEN

To assess the identifiability of reproductive planning after genetic counseling, a model was designed to study 8 relevant factors influencing reproductive decisions after genetic counseling. Altogether, 164 couples were interviewed at home 2 to 3 years after genetic counseling. The factors were arranged in a flow chart distinguishing 3 groups: reproductive outcome prior to genetic counseling, desire to have children, and interpretation of information gained from genetic counseling. The model based upon these retrospective data showed that reproductive decisions were identified correctly in 91% of the cases. The model consisted of 8 factors and documented the urgency of the desire to have children and the interpretation of the genetic risk. In addition, linear discriminant analysis of the 8 relevant factors enabled identification of the reproductive decision in 96% of the cases. This model may prove helpful to counselors and counselees by showing what other couples have decided in comparable circumstances and for which reasons.

RESUMEN

Our experience with the first family in the Netherlands for whom predictive DNA-testing for Hereditary Breast and Ovarian Cancer (HBOC) became an option is described. This serves to illustrate the complex emotional impact on a family as a whole, and upon the members separately, of becoming aware that breast and ovarian cancer is hereditary, and the implications of undergoing predictive testing. All family members received genetic counseling and were offered pre- and post-test psychological follow-up. We observed two important roles within the family. One member became "the messenger of the news" informing the relatives of the hereditary character of cancer in the family. Another was "the first utilizer" of the new options; namely, the predictive DNA-test and preventive surgery. This first utilizer became the example to the rest of the family. Decisions made about preventive treatment (prophylactic ovariectomy and/or mastectomy) were based on the experiences within the family, whether one identified with an affected family member with breast or with ovarian cancer. The actions and reactions perceived were illustrative of what kind of support provisions should be provided in addition to the genetic and oncological counseling for HBOC. Moreover HBOC should be considered both as an individual and a family problem and be treated as such in genetic counseling.

RESUMEN

Here we report a follow-up study involving interviews with 164 couples 2-3 years after genetic counseling to assess the influence of various factors on their reproductive planning. The results show that the desire to have children and the absence of personal experience with the disorder (no close relative being affected) are important single factors for the decision to opt for having children after genetic counseling. The magnitude of the genetic risk is of relative importance in reproductive planning. Seventy percent of the couples with a high genetic risk (greater than 15%) opted for having children. When the disorder was perceived as severe and the risk was interpreted as high, 72% opted for having children. The availability of prenatal diagnosis became important only in combination with a high genetic risk (greater than 15%). Forty-seven percent of the couples with a high genetic risk refrained from having children when prenatal diagnosis was not available. In the absence of prenatal diagnosis, couples who had an affected child were more cautious about trying again than those who did not--50% versus 14% decided to abstain. This study has provided some insight into the complexity of reproductive decision-making after genetic counseling. The findings may help genetic counselors and clinical geneticists understand and support counselees in their decision-making process, which is "multi-factorial."

RESUMEN

UNLABELLED: In the Dutch presymptomatic DNA-testing program for Huntington disease (HD), 29 individuals with increased risk and 44 with decreased risk were followed-up 6 months after test results. A prognostic model was built aimed at identifying individuals at risk for psychological maladjustment, as measured by the Impact of Event Scale, the Beck Hopelessness Scale, the General Health Questionnaire, and the Social Support Questionnaire. RESULTS: 1) The more that applicants suffered from intrusive feelings about HD and tried to avoid HD-related situations, prior to the test, the greater the chance that they will experience this 6 months after the test if they proved to be at increased risk; 2) the more that both individuals with increased risk and those with decreased risk who suffered from the threat of having HD tried to avoid HD-related situations prior to the test and the less satisfied they were with available support, the greater the probability that they will show avoidance behavior after the test; 3) the more pessimistic that individuals with increased risk as well as those with decreased risk were about their future prior to the test, the more they avoided HD-related situations and the more dissatisfied they were about their available support (pretest), the greater the probability that they will become depressive and suicidal. Psychological adjustment was also studied as a function of a) intrusion/denial-avoidance pattern over time and b) healthy mental functioning/future expectancies. Most individuals with increased risk (86%) seem to cope well thus far, although this was based largely on strong psychological defenses and dependent on satisfactory relationships.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMEN

We have studied the 6-month follow-up attitudes of 63 individuals, after predictive testing for Huntington disease (HD). Reducing uncertainty (81%) and family planning (60%) were the major reasons for taking the test. Twenty-four individuals were diagnosed as having an increased risk (+/- 98%), and 39 a decreased risk (+/- 2%). Among those with an increased risk, denial or minimization of the ultimate impact of the increased risk result was observed. Most of them (84%) rated their current life situation, at the very least, as being good. Twenty-one percent of individuals with an increased risk who originally planned to have a family, decided to refrain from having children. Sixty percent of those with increased risk who still wished to have children, would choose to have prenatal testing. In most individuals with increased risk, the test result did not increase the previously expected control over their own future. Half of the partners of persons with increased risk acknowledged the burden of the future disease. Half had no one in whom they could confide. They showed loyalty to the denial and avoidance reactions of their spouses. Half of the individuals with decreased risk denied the impact of the result, as reflected by absence of relief, and emotional numbness. A third of persons with decreased risk experienced involvement with problems of affected relatives. We found that 20% of all participants were discontented with the support given by their general practitioner, who is normally regarded as being the most significant professional for aftercare. Our findings suggest that the perpetuation

RESUMEN

We studied the baseline attitudes, prior to testing, of 70 applicants at risk for Huntington disease (HD) and their partners in the Dutch presymptomatic DNA-testing program. Two thirds of the applicants were female; 36% already had children. The main reason (60%) for undertaking the test was for family planning. Other reasons were either to reduce uncertainty (43%) or to obtain certainty (38%). Partners of applicants stated that planning for the future was for them the most important reason (76%). Significantly more at-risk females (42%) than males (16%) anticipated an unfavorable test outcome. Quite remarkably, most applicants and partners denied that a positive result might have adverse effects on either personal mood, quality of life, or marriage. Only a few did not expect that a favorable result would induce relief. The eventual outcome of the test was expected to enable applicants to gain control over their future, whatever the results. Hence, we propose that the applicants form a self-selected group, based on their expectation that they will not be emotionally affected by either result.

RESUMEN

Presymptomatic DNA-testing for Huntington's disease has made it possible to predict whether or not at-risk individuals are gene-carriers with a reliability of about 98%. In our retrospective study of 18 tested individuals, most of the newly identified carriers function apparently well. They use avoidance and repression of affect as psychological defense strategies. However, 8 out of 9 non-carriers do not experience the expected relief about their test results. They experience survivor guilt and emotional numbness and find it difficult to cope with the effects of the test results on the family system. The partners of gene-carriers are at risk of becoming emotionally isolated by putting aside their own feelings for fear of seeming self-centered. Appreciation of these effects on tested individuals is important and professional support is needed to prevent post-traumatic stress disorders. Whatever the test result may be, the working through process may take years rather than months. These findings have important implications for patient care and necessitate an extended period of observation after presymptomatic testing.

RESUMEN

Mutation analysis for autosomal dominant hereditary breast/ovarian cancer genes (BRCA1/BRCA2) became an important technique for women at risk of carrying these mutations. Healthy female mutation carriers have a high lifetime risk for breast and/or ovarian cancer and may opt for frequent breast and ovary surveillance or prophylactic surgery (mastectomy and/or oophorectomy). Psychological distress was assessed in 78 healthy women at risk of having inherited a BRCA1/BRCA2 mutation opting for genetic testing and 56 partners several weeks prior to ("pre-test") and after ("post-test") learning about their DNA test result. Twenty-five women were found to be mutation carriers, and 53 were non-mutation carriers. One goal of the study was to identify individuals at risk for high distress in the weeks following disclosure of the test result. Interview transcripts were used to give a fuller picture of pre- and post-test distress. High post-test anxiety was reported by 20% of the mutation carrier women and by 35% of their partners. Eleven percent of women without the mutation and 13% of their partners reported high post-test anxiety levels. High post-test anxiety in women was significantly related to 1) a high level of pre-test anxiety and 2) being a mutation carrier. Women without a mutation who had a sister identified as a mutation carrier recently had higher post-test levels of depression than the other non-mutation carriers. It is suggested to consider seriously the need for psychological support in mutation carriers who had been anxious at pre-test already. For most non-mutation carriers, psychological follow-up might be of lesser importance, but those having a sister receiving an unfavorable test result should be informed about the possibility that they might not feel relief.

RESUMEN

In an exploratory study of 12 couples the emotional reactions to the birth of a child with extensive anatomical malformation were investigated retrospectively, using semistructured interviews (on average 18 months after the birth). The couples were selected from the group of parents of children admitted between January 1986 and August 1988 to the Paediatric Intensive Care Unit of the Sophia Hospital, Rotterdam. The couples were divided into three groups: those who had had no ultrasonography during the pregnancy (n = 4), those in whom ultrasonography during pregnancy had revealed a foetal abnormality (n = 4) and those in whose children no such diagnoses had been made at ultrasonography during pregnancy (n = 4). After the birth of a child with congenital abnormalities, most parental couples displayed a shock reaction, denial, anger and hurt. In general there was no difference in emotional reaction between the three groups. In all couples the mourning process appeared to have begun only after the birth. Parents of a child with clearly visible abnormalities appeared to have more problems. Two-thirds of the couples had accepted the child's anomaly after some time. Persistent anger, feelings of guilt and anxiety are probably due to uncertainty regarding complications in the child or another pregnancy. Teams treating a child with a congenital anomaly should be aware of the consequences for the parents and should regard support of the parents as an essential part of their task.

RESUMEN

Presymptomatic DNA diagnostics in Huntington's chorea make it possible to establish with approx. 98% certainty whether an at-risk person is a gene carrier. Sympathy and care are usually shown to those demonstrated to have the gene and so will become affected in the future. Persons shown not to be carriers sometimes do not experience the expected relief. The authors successively discuss the effects of a favourable finding on the family system, such as survivor's guilt and emotional numbing as aspects of a coping process. It is concluded that even a favourable finding needs to be worked through, a process that takes years rather than months.

RESUMEN

Studies from the last decade on factors influencing reproductive planning after genetic counselling were reviewed. Increased possibilities of DNA-analysis and prenatal diagnosis might have brought about a shift in the paramountcy of factors influencing reproductive planning after genetic counselling. In contrast to the literature in the seventies, the magnitude of the genetic risk was no longer found to be one of the decisive factors in postcounselling reproductive planning. Instead, the interpretation of the risk as high or low and the desire to have children appeared to be paramount. The impact of new developments in DNA-analysis in prenatal diagnosis and presymptomatic testing will be an important subject for future studies on factors influencing reproductive planning.

RESUMEN

To investigate the factors influencing whether or not couples seek genetic counselling, the parents of 37 children with a major congenital anomaly were interviewed at home. All the children had been admitted to the Intensive Care Unit (ICU) of the Department of Paediatric Surgery. After physical examination of the child, the consultant clinical geneticist stated that genetic counselling was indicated for the parents. Whether they sought genetic counselling was left to the parents to decide. Eighteen of the 37 parents had sought genetic counselling. Assessment of the joint influence of a number of factors revealed that two factors were separately paramount in distinguishing between couples who did seek genetic counselling and those who did not: whether parents considered genetic counselling useful in their case shortly after the birth of their affected child, and whether the couple was clearly and correctly informed about the indication for genetic counselling. The intention to have a subsequent pregnancy was not associated with whether or not couples sought genetic counselling. Loss of information was observed: 1/3 of the referrals for genetic counselling mentioned on the written consultation forms were not stated in the discharge letters. This loss of information could have been reduced by a) routinely including the indication for genetic counselling in the discharge letter and b) appointing a coordinating physician to ensure that the parents were informed clearly about the availability of genetic counselling. Resistance to genetic counselling needs to be respected by the physician. Exploring its background might help to reduce this resistance.

RESUMEN

The emotional reactions of parents and adult patients on disclosure of the clinical diagnosis of androgen insensitivity syndrome (AIS) and its later confirmation by gene mutation analysis were assessed. A semistructured interview and three questionnaires were used. Parents came from 18 different families with a total of 20 children (15 complete AIS, 5 partial AIS), 19 raised as girls, 1 as a boy. Ten adult women with complete AIS came from six families. The short-term reaction upon the clinical diagnosis was in the majority of both parents and adult patients associated with shock, grief, anger, and shame and in the mothers and adult patients with guilt. Emotional reactions were more long-lasting in mothers and adult patients than in fathers. The confirmation by DNA analysis did not alter the actual feelings of both parents. Adolescents with AIS should be informed completely - but in a step-by-step way - about their condition, since adult patients indicated that they had suffered from being not at all or misinformed about AIS in their adolescence.

RESUMEN

The psychometric qualities of the Perinatal Grief Scale (PGS) were evaluated in a sample of 46 Dutch women in late pregnancy (> or = 24 weeks), who had been informed of the diagnosis 'lethal or severe fetal malformation'. The validity was assessed by comparing it to the Impact of Event Scale and to a clinical diagnosis of psychological instability. The PGS appeared to be internally consistent and particularly strongly related to psychological instability. It can therefore be considered as a valid assessment instrument, also for women who experience late pregnancy loss.
